How to Clean, Lubricate and Inspect Your Wire Grips

Inspect Your Wire GripsTo keep your wire grips in good working condition, it’s important that you properly clean, lubricate and inspect your wire grips on a regular basis. This will help prevent issues and potential accidents out in the field.

Follow the procedures below to ensure your grips are properly cared for.

Cleaning and Lubrication

  • Step 1: Clean the surfaces of the grip jaws using a cloth or round wire brush.
  • Step 2: Spray all joints and moving parts, including the jaws, with degreaser. Then, use a round wire brush to remove any dirt from the jaws.
  • Step 3: Once clean, wipe the wire grips until they are dry. If grips are still dirty, repeat steps as needed.
  • Step 4: Lubricate all joints and any moving parts. The surfaces of the grip jaws should not be lubricated.

Inspection

To inspect the wire grip:

  • Step 1: Carefully examine the jaws for clogged, damaged, or missing teeth.
  • Step 2: Check that the jaws and other parts of the grip are aligned to ensure that there is no distortion.
  • Step 3: Open and close the grip to ensure it completely and smoothly opens and closes.
  • Step 4: Finally, check all other parts and joints for any distortion and/or wear.

During the inspection, if you find that the grip is bent or distorted, it should be thrown away and replaced. It should NOT be repaired.

How to Properly Inspect Your Lever Strap Hoist

How to Properly Inspect Your Lever Strap Hoist

lever strap hoistWhen it comes to lever hoists, utility professionals rely on a variety of different hoists to get the job done. One of the most popular hoists for utility applications is the lever strap hoist. When using a lever strap hoist, it’s important to inspect it regularly to prevent accidents or product failures. These inspections are broken down into frequent and periodic inspections.

Frequent Hoist Inspections for Your Lever Strap Hoist

Frequent inspections are what we refer to as pre-operational inspections. In addition to these inspections, visual observations should be conducted during regular service of these hoists to check for any damage. Any deficiencies should be carefully examined and a determination made as to whether they constitute a hazard. During the inspection, check:

  • All functional operating mechanisms for maladjustment interfering with proper operation
  • Hooks and latches for deformation, chemical damage, cracks and wear
  • Hook latches for proper attachment and operation
  • Levers for bends, cracks or other damage
  • Damage to the support of the hoist

Also, at the beginning of each shift, the web strap should be visually inspected to identify any major damage that could cause an immediate hazard, such as melting or charring, weld splatter, broken stitching, damaged eyes, etc.

Periodic Hoist Inspections for Your Lever Strap Hoist

Periodic inspections are thorough, detailed inspections that may require complete disassembly of the hoist. These should be performed by an appointed person. These inspections should include:

  • A designated person determining whether conditions found during the inspection constitute a hazard and if disassembly is required
  • Checking fasteners for evidence of loosening
  • Checking the web strap, suspension frame, levers, yokes, shafts, pins, rollers and locking/clamping devices for evidence of wear, corrosion, cracks and distortion

Special care should be taken when inspecting sections of the web strap for rapid deterioration, including sections:

  • In contact with saddles, equalizer sheaves or other sheaves where web strap travel is limited
  • At or near the ends where broken threads or cuts may be evident
  • Subject to reverse bends that are normally hidden during visual inspection, such as sections passing over sheaves
