Q & A: Are there Any Special Load Test Requirements for a 50 Ton Crane?

Q & A: Are there Any Special Load Test Requirements for a 50 Ton Crane?


Kyle asks the following question about load testing:

A  company I work with conducts a special lift twice a year where they lift 100,000 lbs. with a 50 Ton crane.  Are there any special requirements as far as load testing, inspections or OSHA requirements that need to be considered when doing this lift?  If so, could we get them in writing?

Tom answers:

Since 100,000 lbs. is 50 Tons, and the capacity of their crane is 50 tons, nothing special is required. They can legally do this all day long as many times as they want (within the CMAA Class of the crane).

On the other hand, if a crane owner wants to lift a load that exceeds the rated capacity of the crane, that owner may do so twice in a 12 month period.  ASME B30 standards refer to this as a “Planned Engineered Lift.”   The requirements can be found in the appropriate ASME B30 Standard, Section three (3). Please review and follow the standards as published.

To summarize, the following conditions must be met:

1.  Review the service/maintenance history of the crane.

2.  A Periodic Inspection must be conducted just prior to the lift and immediately following the lift.

3.  This type of lift is restricted to powered cranes and hoists rated at 5 tons or greater.

4.  The load shall not exceed 125% of the rated load of the crane or hoist.

5.  This event is limited to twice in a twelve-month period.

6.  A written report, documenting all aspects of the event, must be  placed on file. Documentation is very important and needs to be emphasized.

TomReardon_rev1 MCM Events welcomes another speaker at the jointly held Crane & Rigging Conference and Industrial Crane & Hoist Conference at the Hampton Inn Hotel & Suites New Orleans-Convention Center, New Orleans, La. The conferences will take place May 23-24, 2012. Tom Reardon, Training Manager, Hoists and Cranes, for Columbus McKinnon Corporation, will provide an overview of OSHA 1910.179, as well as explore crane configurations, regulations, and standards for the industry.
“Many of us have experienced the concern prompted by crane inspection reports listing discrepancies as OSHA violations. Not all of these reports are accurate,” says Reardon. “Some confusion exists among crane and hoist owners, users, and service providers regarding crane configurations and the application of OSHA 1910.179 regulations.”

Reardon is inviting industry stakeholders to submit questions regarding standards and regulations, to which he will source answers from ASME/ANSI, OSHA, CMAA, etc., and share them with delegates at the end of his presentation.

Highlights from the Spring ACRP Meeting

Highlights from the Spring ACRP Meeting








The Association of Crane and Rigging Professionals (ACRP) recently held its annual meeting in Milwaukee, Wisconsin.

The ACRP is a nonprofit association whose mission is dedicated to improving crane operations and rigging activities in all industries. This is accomplished through educational opportunities to its members and the public. Many ACRP members are heavily involved with other organizations such as ASME, NACM, CMMA to name a few. Columbus McKinnon has board representation and also participates in the educational opportunities.

This year’s meeting theme was Crane Operation Safety.  Topics of discussion included:

  • D/d Ratio of Alloy Sling Chain
  • Turning Pre Cast Loads Safely on the Job Site
  • Design and Safety Criteria for Pad Eyes and Eyebolts
  • ASME Update on P30: ASME P30 is the newest “in development” standard under the ASME umbrella. The intent of this document is to provide end-users with an exceptional guideline that focuses on personnel, equipment and procedures as they relate to repetitive lifts, standard lifts and critical lifts.
  • Boom Assembly / Disassembly
  • How to Find and Calculate the Center of Gravity
  • Responsibilities of Crane Operations
  • How an Overhead Hoist Works (presented by Columbus McKinnon)
  • Critical Lift with Overhead Cranes
  • Derrick Barge Lift
  • Industrial Rollers
  • Overhead Crane Standards and Regulation Update

Each of the topics provided case studies and applications. There was also a tour of the Manitowoc Crane Production Facility. All cranes and attachments manufactured at the Manitowoc facility are rigged and tested in the 20 acre test yard. The machines are tested to ensure the safety, quality and functionality of the delivered product. Currently being tested in the yard was a 2300 metric ton crane. It was the largest capacity crawler ever designed and built by Manitowoc.

ACRP is where Trainers get Trained. Information is openly shared and is provided to members of ACRP for use in their own training programs.

The Twenty Year Rule

The Twenty Year Rule

twenty year rule While conducting our overhead lifting safety training it never fails that we get a comment to the effect of,

We’ve been doing it this way for over twenty years. We never had an accident.  And, now you are telling me it’s wrong?”

Just because you have been lifting a certain way for the past twenty years and never had an accident only means that you have been lucky. When performing safety training we emphasize all the safety standards and regulations that are applicable. They all serve a purpose.

When performing safety training we emphasize all the safety standards and regulations that are applicable. They all serve a purpose.

ANSI/ASME B30 Safety Standards for overhead lifting began in 1916 as an eight page safety code – now 94 years old. Crane Manufacturers Association of America (CMAA) began as Electric Overhead Crane Institute (EOCI) in 1927 and published their first standard in 1948 –  62 years old. ANSI/NFPA 70, otherwise known as the National Electric Code began in 1897 – 113 years old. Article 610 of the NEC is specifically written for overhead cranes and hoists. For our friends north of the border, the CSA standard B167.08 began in 1964  – 46 years old. Finally, let us not forget OSHA, which began in 1970, making it 40 years old.  OSHA enforces two federal regulations for overhead lifting:  CFR 1910.179 for cranes and 1910.184 for slings. Between all these organizations and safety standards there is a total of 355 years of experience. 355 years trumps your 20 every time.

These organizations were not put together to make your life miserable.  You can’t take short cuts the way you have been doing the past twenty years.  These organizations include people that are involved in all facets of overhead lifting, including riggers and production and construction personnel that perform overhead lifting as part of their job.  They want you to be safe in your work habits and environment so that you can go home at the end of your shift or work day to your family.
