The CM Man Guard: CSA Approved for the Canadian Market

The CM Man Guard: CSA Approved for the Canadian Market

CM Man Guard

Columbus McKinnon recently launched the CM Man Guard electric chain hoist with CSA approval for the Canadian market. To explain the importance of CSA approval and discuss the features of this great hoist, we interviewed our Canadian National Sales Manager, Chris Siabanis.

What is CSA approval?

The Canadian Standards Association (CSA) is an independent third-party testing and certification organization. CSA tests products and their components, as well as audits manufacturing processes to ensure products meet or exceed the necessary codes, specifications and accredited standards for sale into the Canadian marketplace. Products must be CSA approved to be sold in Canada.

Since its launch in September 2011, the CM Man Guard has been well-received in the U.S. So, we felt that it would be an excellent addition to our Canadian product portfolio as well. That’s why we pursued CSA approval.

What are the key features of the CM Man Guard?

CM Man GuardKnown for reliable performance and best-in-class safety features, the CM Man Guard is a competitively priced hoist option and is available in capacities ranging from 1/4 to 3 tons with standard lifts up to 20 feet. It also has a lifetime guarantee.
Some key features of this hoist that are most important to customers include:

  • H4 duty motors that allow the hoist to be used in high-duty-cycle environments. We are able to achieve H4 duty rating using higher quality components and do not require the aid of a fan to cool the motor, unlike competitors’ hoists.
  • Efficient low-cost operation that saves you money. The Man Guard’s specially engineered motor and precision-machined gearing reduce the electrical demand required to operate the hoist. Single-phase and three-phase amp draws are, on average, 50% less than the equivalent competitors’ models. Less electrical demand per hoist can add up to big operating cost savings.
  • Made in the USA and stocked in Canada ensuring availability. Manufactured in our Damascus, Virginia facility, these hoists and repair parts are readily available for delivery from our Canadian warehouses located in Cobourg, Ontario and Edmonton, Alberta.

What is ISG and what are the benefits to the customer?

Aside from all its great features, the CM Man Guard is part of our In-Stock Guarantee (ISG). Our In-Stock Guarantee (ISG) is our commitment to shipping our most popular chain, hoists and rigging products in 3 days or less. The CM Man Guard is our first electric chain hoist available through ISG, with more than 40 models in-stock and ready to ship, including 575V 2-speed units. This is a game changer for the industry.

Man Guard models available through the In-Stock Guarantee include:

  • Hook mount 1/4, 1/2, 1 and 2 ton units with 10, 15 and 20 foot lifts at 16 fpm
  • Hook mount 3 ton units with 10, 15 and 20 foot lifts at 5 and 10 fpm

Are there new features or changes coming soon for the CM Man Guard?

We are currently developing a lug mount for the CM Man Guard that can be used with the Universal Trolley. The UT Trolley allows you to use one trolley with a variety of CM air and electric chain hoists. It provides flexibility with inventory while reducing the need to stock trolleys for each model of CM chain and air chain hoist you use or carry, including the Man Guard.

The True Meaning of the Name “Lodestar”

The True Meaning of the Name “Lodestar”

Lodestar

Our entertainment trainer, Dave Carmack, travels the world to teach and share important information about entertainment rigging and hoisting safety. At the end of his classes, he likes to stump his students with this question: “Can you tell me why we spell our hoist, LODESTAR, instead of LOADSTAR?”

Dave was asked this question many years ago by a student, which prompted him to do some research. Reaching out to Columbus McKinnon engineers, Dave finally found the answer.

“Lodestar” is defined as a guiding star. In 1955, when the first industrial Lodestar was introduced, many of our hoists had galactic names like Meteor, Satellite, and Comet. It was the first of many unique products that Columbus McKinnon brought to the material handling industry, which also included aluminum hoist frames, the Weston-Type brake, and the first alloy chain.
In a recent CM-ET class, Jamie, a CMCO training course attendee from Canton, Michigan wrote this answer:

“A Lodestar is one that serves as an inspiration, model or guide. The Lodestar hoist was engineered and designed to be a leader and model in the entertainment industry.”

We couldn’t have said it better ourselves!

How to Choose Hoists & Cranes for Offshore Applications

How to Choose Hoists & Cranes for Offshore Applications

Proper selection and specification of hoists, cranes and rigging hardware is always essential to safe overhead lifting, but in no environment is this more critical than on offshore oil and gas facilities.

In offshore oil and gas applications, there is a higher potential for flammable gases to be present. Therefore it is extremely important that proper safety precautions are taken to protect workers aboard these vessels and prevent equipment damage. It is important that the individuals responsible for specifying and purchasing material handling equipment for use in these environments can properly identify any hazardous locations or areas per the U.S. National Electric Code (NFPA 70), IEC Standard 60079, and other applicable local, national and international standards to ensure compliance with these regulations and safe operation. Additionally, the use of mechanically spark-resistant materials should be strongly considered, although these materials are not specifically addressed within many of the referenced standards.

In the absence of a definitive industry standard specifying what constitutes spark-resistant construction for hoists and cranes, it is frequently left to the knowledge and discretion of the seller to determine what materials will be used unless the purchaser designates specific requirements. If not clearly defined in the bid specification, the product and spark-resistant features provided often depend on the sourcing channels utilized by the end user.

Columbus McKinnon manufactures many products specifically designed for applications that require spark-resistant features. Our diverse, made in-America portfolio of hoists and trolleys are built to suit, rather than a mass produced “one size fits all” approach. Many of the products lend themselves to modification and substitution of materials that allows us to configure our hoists and trolleys to the specific application.

  • Chester Hoist products utilize solid spark-resistant materials such as bronze hooks, trolley wheels and brake ratchets as well as stainless steel load chain, hand chain and hook latches. In some cases it is necessary to use nickel-diffused chains or copper-plated hooks due to headroom constraints or to reduce costs for equipment that will be used infrequently or in temporary applications. In these cases, Chester also can provide plated components to reduce costs. For equipment that is relied on heavily and is required to maintain spark and corrosion-resistant qualities for the life of the equipment, we actively promote the lasting protection of solid spark and corrosion-resistant materials rather than plated components. 
Explosion Proof Cable King Hoist
Explosion Proof Global King Hoist

 

 

  • Yale Cable King wire rope hoists can be supplied in a wide range of capacities, lifting speeds and configurations with both spark and explosion resistance. The Cable King is  available in a spark-resistant pneumatic model and an explosion-proof electric model, for Class 1, Division 1 or 2, Group C & D; and Class 2, Division 1 or 2, Group E, F & G.

Special consideration should also be given to the environmental conditions at the work site, including temperature extremes, humidity, corrosive atmospheres and the potential for dynamic loading due to vessel motion. Special materials, testing, material certifications and design modifications may be required to ensure safe operation and minimal down time of lifting equipment. Additional factors such as headroom clearance, end approach, frequency of use and the availability of utilities (electricity, compressed air) must also be considered.

Reading and understanding applicable safety standards and consulting with experienced and reputable manufacturers are two important steps in ensuring operator and facility safety when selecting hoists, cranes and rigging hardware for offshore applications.

D8+ Hoists and Suspending Loads over People in the Entertainment Industry

D8+ Hoists and Suspending Loads over People in the Entertainment Industry

D8+ Hoists

Suspending loads above people is common practice in the entertainment world and requires great precautions. In Europe, one voluntary Code of Practice guides the product specifications and installation requirements surrounding these applications: SQP2 Chain hoists (2010).

U.S. interest in this European Code of Practice is growing as this code is being adopted in U.S. entertainment installations. Our distributor, Atlanta Rigging has recently completed installations at Bankers’s Life Fieldhouse, in Indianapolis, Indiana (shown above) and at the Barclays Center in New York which include D8+ hoists and meet this voluntary European code.

European Code of Practice and the D8+ Code

The SQP2 defines the D8+ as “The D8 Plus Electric chain hoist is constructed and dimensioned in such a way that the moving of overhead loads is possible provided that no persons are standing under the load and that it is not necessary to install safety backups when the hoist is switched off.”

Once the load has been lifted, is in place and the hoist has been switched off, then it is acceptable to suspend the load above people without the secondary support. While the load is moving all personnel should be out from underneath the load.

How the D8+ Code can be attained

The D8+ “code” can be achieved by having a minimum of 10:1 design factor, double brakes and a clutch. The clutch can be used as protection against overloading when the hoists are used for statically determinate loads. A statically determinate load is defined in the SQP2 as a load on individual electric chain hoists (point load), distributed loads on two electric chain hoists, hinged, linked single span girders on more than two electric chain hoists, and distributed loads on three electric chain hoists.

Banker’s Life Fieldhouse Application

Banker’s Life Fieldhouse Application – Indianapolis, Indiana

The Banker’s Life Fieldhouse installation shown utilizes twelve (12) Columbus McKinnon D8+ Model RR Chain Hoists with 123’ of lift. There are two (2) hoists used per speaker line array and a total of six (6) arrays.

The control system, provided by Motion Laboratories, consists of the following: 16‐Channel Controller with Soft Limit System, Touchscreen Handheld Remote and Remote E‐stops.

CM ShopStar Brings Speed and Safety to Stewart-Haas Racing Team

CM ShopStar Brings Speed and Safety to Stewart-Haas Racing Team

If you follow NASCAR then there’s no doubt you are familiar with Stewart-Haas Racing – the title-winning NASCAR Spring Cup Series team made up of Tony Stewart, Ryan Newman and Danica Patrick.

But did you know that Stewart-Haas Racing relies on CM ShopStar electric chain hoists to build and repair their cars? To find out more about how they’re using the ShopStar, Ken Tilson, CMCO Product Manager – Powered Chain Hoists, and I took a trip to their headquarters in Kannapolis, North Carolina.

Stewart-Haas Racing utilizes an overhead crane system featuring six CM ShopStar electric chain hoists that are paired over three car-assembly areas to position NASCAR design templates onto cars under construction in their primary garage. An additional single CM ShopStar with 500 lb. capacity is used in their Research and Development Area.1-ShopStar

Why did they choose the CM ShopStar?
In the past, the Stewart-Haas crew used a common electric wire rope winch mounted to a mobile A-frame gantry to lift and position their car design templates. That system had slow lifting speeds and an unreliable brake that made this process both tedious and dangerous for the crew. The team converted to the CM ShopStar for its speed, dependability and dual braking system to make the process more efficient and safe.

To learn more about CM’s involvement with Stewart-Haas Racing, check out the full case study or view our video online.

Special thanks to the entire team at Stewart-Haas Racing for the opportunity to tour their facility and the time they took to show us how they are using our product.

JLC Chain Hoists – American Pride and Almost 40 Years Strong

JLC Chain Hoists – American Pride and Almost 40 Years Strong

Teamwork around the JLC

The favorite part of my job is working with so many great people at Columbus McKinnon who work in the different facilities and departments of our organization. One thing I’ve discovered is that all of of my fellow associates take great pride in the products we produce, and their enthusiasm overflows into everything that we do. I was witness to another demonstration of this excitement during a recent discussion about our JLC chain hoist series and its upcoming 40th year anniversary.

So I made a call to Joe Ombrello, General Manager of our Wadesboro, North Carolina Operations, to learn more about this special electric chain hoist series. Here is what he had to say in response to my questions:

“When was the first hoist in the JLC Series built?”

As you know, the current JLC has 3 predecessors. Its lineage dates back to 1974 with the first JF Model. Next the ELC series with a clutch and an oil filled gear case started around 1979. Our JL version (JL1.0) went into production in 2002. It was then upgraded to our current JLC model in 2010. In a nutshell, we have been making this product series for almost 40 years!

“Did we purchase this technology from someone or did we develop it on our own?”

The technology was developed internally by our Coffing Hoist engineering department in Wadesboro, North Carolina.

“Please share with me the most interesting customer application story ever told about the JLC.”

Over 40 Coffing JLC hoists were used in the 2008 Olympics in Beijing, China to suspend trusses in the swimming arena.

08082602 08082605_

 “Is there anything else that you would like to share from your background and experience that you think others might find interesting?”

The Coffing JF hoists were used in the 1960’s by the United States military for nuclear warhead maintenance and handling. Our JF hoist was also the original concert hoist used by the Grateful Dead in the early 70’s. Today, our JLC hoist can be found in sporting and entertainment arenas all over the world and is used by touring concerts for Garth Brooks, Reba McIntyre and Toby Keith.

Best of all, the JLC product series – along with the CM Lodestar – are made in America. That is something everyone here in Wadesboro, North Carolina is very proud of. We share that feeling of pride with our fellow Associates at our Damascus, Virginia Operations who manufacture the CM Valustar, Man Guard and ShopStar electric chain hoists.

In what application do you use our JLC chain hoist?

Recent Sight and Sound Theatre Installation Incorporates the Latest of American Technology

Recent Sight and Sound Theatre Installation Incorporates the Latest of American Technology

 

PA-Theatre-Interior

Sight and Sound Theatre, the largest faith-based theatre in America, partnered with Mountain Productions to complete a full and permanent hoist/motor installation at their Lancaster County, PA theatre.  Using all American Made chain hoists provided by Columbus McKinnon, Mountain Productions prepared and coordinated the package for ease of installation, while Motion Labs provided the electrics, controllers and programming. Sight and Sound continues its tradition of using the most state-of-the-art equipment to maintain the highest quality productions for which the theatre is famous.

D8+ Chain Hoists are the hoist of choice in theatre applications.

IMG_7798
Sight and Sound selected our new model Lodestar D8 chain hoists, (1 ton -Model L – and 1/2 ton – Model F), featuring a double brake on each hoist.  The Lodestar D8 is legendary in the industry, and we have recently added several features to the hoist, further ensuring steady and reliable operation.

Along with the Lodestar D8 units, Prostar chain hoists were also installed. The Prostar is a lighter, quieter and more portable hoist that is designed for unique rigging applications in tight quarters. Combined, the Lodestar D8 and Prostar offer versatility, allowing for a variety of rigging configurations at the theatre.

The motor control and load monitoring systems were supplied by Motion Laboratories, a cutting edge company known for their high quality power distribution and motor control systems. The state-of-the-art PLC touchscreen system handles motor control and load monitoring at the theatre. The ability to program specific presets into the system makes the PLC an efficient motor control/load monitoring solution. Sight and Sound’s professional riggers will be able to lower and raise loads with ease, and rely on the system’s precision to always keep equipment on point.  Load Cells will be used for accurate load monitoring, supporting the safety of the system.

New rigging grid reduces maintenance time and show preparation.

One of the key benefits of this system is the amount of time the theatre will save on maintenance and preparation for shows. Glen Broderson from Sight and Sound led his team in making the decision to install the new rigging grid. He expressed how much easier it will be to pinpoint individual electrics for maintenance thanks to the soft limit system. This also makes prep time between productions quicker and more convenient. “With the new system, going from a 40 ft trim to a 30 ft trim is just a push of a few buttons,” Glen shared. The whole process has been valuable to Glen and his team.  Everyone is excited to see how the theatre will use the installation in future productions.

Sight and Sound Theatre

Always striving to push the envelope with new technology and productions, the Sight and Sound Theatre remains an innovator in the theatrical industry. If you happen to be in the neighborhood, consider checking out their latest production of Noah. 

Thank you to Mountain Productions, for sharing this application story and to the Sight & Sound Theatre  for use of their photography.  For more original photos of this installation, check out  Mountain Productions’ Blog.

Yale Global King Now Available with Explosion Proof Options

Yale Global King Now Available with Explosion Proof Options

Global Wire Rope Hoist Explosion Proof Columbus McKinnon has a long history of supplying equipment for use in hazardous environments. We just launched our newest entry into this market:  the Yale Global King Explosion-Proof Wire Rope Hoist designed to meet Division 2, Class I, Groups B, C & D requirements where flammable gases, vapors and liquids are present.

Explosion-Proof Classifications & Environments
To someone relatively unfamiliar with Explosion-Proof classifications & environments, their requirements can be a little confusing and are often misconstrued. The first thing to remember about explosion-proof hoists is they are not really explosion-proof at all, but rather designed with modifications to contain explosions or flames without igniting the surrounding environment.

In North America, almost all explosion-proof hoists are built per classifications outlined by the National Electric Code under the categories of Division, Class & Group. Please refer to our brochure for complete information on the features of the Yale Global King Explosion-Proof Wire Rope Hoist as well as a breakdown of the Division 2, Class I, Groups B, C & D environments.

Mechanical spark-resistant features are often misidentified as being part of the requirements for explosion-proof hoists. That’s not really the case at all. When defining its requirements for electrical equipment used in hazardous environments, the National Electric Code does not refer to mechanical spark-resistant features. These features would have to be specifically referenced, in addition to the explosion-proof modifications, if they are required. It is the responsibility of the user and the local governing authority to determine what type of hazardous location is present and if mechanical spark-resistant features are also required. In some cases, mechanical spark-resistance might be deemed necessary, but there are also many instances in which Division 2, Class I, Group B, C & D hazardous location hoists are provided and mechanical spark-resistance is not required.

X-proof industries
Features of our Explosion-Proof Hoist
The Yale Global King is one of the most rugged & easy to maintain hoists in the industry. It is equipped with a 2-speed hoist & trolley control as standard equipment and has an ultra low-headroom design.

We have built the explosion-proof models with the control enclosure pre-mounted in a manner so that there are minimal increases to the overall size of the unit. Combining the explosion-proof features with the popular Global King hoist was a natural fit and one that was requested of the industry. The Yale Global King Explosion-Proof Wire Rope Hoist offers a competitive price & delivery solution to meet Division 2, Class I, Group B, C & D requirements. We will continue to address other hazardous location environments as possible additions to the Global King Explosion-Proof hoist portfolio. If for some reason the Global King does not meet your requirements, you can be sure that Columbus McKinnon has an alternate solution that will suit your needs.

Explosion-proof modifications are available on 5, 7-1/2 and 10 metric ton capacity hoists in both underhung and top-running motorized trolley configurations. We also offer the explosion-proof features for hoists branded under the Shaw-Box World Series name. These modifications are available on hoists wired for a number of common power supplies including 208V-3PH-60HZ, 230V-3PH-60HZ, 380V-3PH-50HZ, 380V-3PH-60HZ, 460V-3PH-60HZ and 575V-3PH-60HZ.

Our Answer to this Week’s Post, “What’s wrong with this Entertainment Application?”

Our Answer to this Week’s Post, “What’s wrong with this Entertainment Application?”

Dave Carmack 8-28-12

Thank you, Tim & Harris, for your comments. We also received interesting insights on our Facebook page. You know your rigging!  Here is my take on this application:

This is a wire rope support grid. These 1 foot squares allow a rigger to quickly position light loads in specific spots by dropping in a rope through the appropriate square. The anchor point is fixed up above the structure. Notice the strap in the background.

Let’s now address the problems:

  • The thing that jumped out  most to me was the construction of the grid.  The wire ropes must be woven or knitted together.  These were not.  Each overlap should alternate over and under.  This installation has all the ropes in the same direction and on the same side.  The weaving should run in the x and y directions.
  • U-bolts are used to connect each overlap. Since the grid installation itself is wrong, U-bolts are not an acceptable option. U-bolts are typically used for light weight or minor connections such as conduit to a pole. I do not think that you could get the clamping force needed using U-bolts to keep the wire rope cables from slipping under a side force. Wire rope clamps are designed for use with cables.
  • A few of you observed the missing nut on one of the U-bolt assemblies. Nice catch.

When a wire rope support grid is assembled correctly, it transfers the stresses.  When the grid is assembled like in this application, the neighboring ropes are not supporting anything, which can lead to very unfavorable consequences.

We are passionate about education and training.  If you would like to tap into training opportunities in the entertainment field, click here to see our schedule.

Thank you again to everyone who submitted comments. We love to hear from you!  Do you have an application you would like us to review?
