Overhead Crane and Hoist Inspections, Missouri, Illinois, Indiana, Kansas, Arkansas, Mississippi, Nebraska, Tennessee, Kentucky, Iowa, and Oklahoma
Why Inspect Overhead Cranes
There are several reasons why to inspect bridge cranes. The most important reason is wear and tear. Just as your car parts wear out with use, the lifting and transporting of heavy object wear trolley wheels, hoist wire ropes, crane flanges, motors and gearboxes. There are two different types of inspections you should consider:
- Monthly or Periodic Inspections - High duty cycle cranes might require inspections more frequently to ensure proper function.
- Annual Inspections - Required by OSHA for most overhead cranes to ensure safe operation of the crane.
Authorities on Overhead Crane and Hoist Inspections
While we at TSOC brush up on our regulatory standards on a regular basis, we encourage you to read the documents yourself. Below are the standard to which OSHA, ANSI, and CMAA specify the regulations and definitions of overhead cranes.
OSHA - 29 CFR 1910.179 - Overhead and Gantry Cranes
OSHA - 29 CFR 1926.550 - Cranes and Derricks
OSHA - 29 CFR 1903.1 (The General Duty Clause)
CMAA - Spec. No. 70 and 74
Crane Operator's Manual ANSI - ANSI/ASME

What Daily Inspections Should End Users Practice?
While monthly and annual inspections are a great way to have professionals ensure safe use of overhead cranes, crane function can change daily. Wire ropes could wear, limit switches could fail, and wear could eventually catch up with a crane depending on use.
Below are a few things your crane operator should run through every day at the beginning of his/her shift.
- Raise Hoist to Upper Limit
- Lower Hoist Completely while checking wire rope fraying.
- Run Hoist Trolley through complete motion
- Run Bridget through complete motion
- Trip Limit switches
- Test safety devices
- Check for air or hydraulic fluid leakage
- Check for load capacity stenciling on both sides of unit.
Monthly Crane and Hoist Inspections
Monthly inspections should be done by trained professionals. Depending on the use at your facility, qualified persons should make a determination whether monthly inspections are necessary. Below are a few items that we look for in our monthly inspections.
- Monthly - Check Crane hooks for deformation or cracks (written record with signature of inspector and date)
- Monthly - Inspect Hoist Wire Rope and Chains for Wear or Distortion (written record with signature of inspector and date)
- Monthly - Inspect Chain for lubrication and add lubrication if needed.
- Check operation mechanisms for excessive wear.
Annual Inspection Items
Annual inspections are a minimum for proper safe use of cranes and hoists. Below are few of the items TSOC looks at during an annual inspection.
- Check for deformed, cracked or corroded members
- Check for loose bolts or rivets typically using such tools as a torque wrench
- Check for worn sheaves and drums and your hoists
- Worn, cracked or distorted parts, such as pins, bearings, gears, rollers, etc.
- Look for excessive wear on disc and shoe brakes typical for crane motors
- Check for wear of chain drive sprockets and chain
- Look at electrical components, such as pushbuttons, limit switches or contactors and check for deterioration.
