OSHA standards 1910.179 requires that overhead cranes and lifting devices are to be load tested. 

​

Load testing is a proof test of your overhead system. The capacity of your overhead system and lifting devices (including below the hook items such as spreader beams) is based off the engineering, design and the completed load test. The capacity rating is 80% of the 125% load your system(s) and lifting devices are tested at. 

Example: 5 ton (10,000lbs) system is to be tested at 125% (12,500lbs) 80% of that 12,500lbs is 10,000lbs (5 tons)

​

Requirements for load testing your overheads

​

1) Installation of a new system and/or structure

2) When modifications are made to an existing systems

3) Derate an existing system

4) If non-OEM parts are used to repair an overhead system

5) Less than 10 tons to be every 10 years

6) More than 10 tons to be every 5 years

​

Recommended reasons to load test outside of required testing

​

1) If your system(s) are used to their fullest capacity on a regular base

2) If excessive wear or abuse is conducted. Example: Flipping loads

3) If you are running multiple shifts with continues usage
