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
