In the loading dock industry, this dangerous situation is called trailer creep (truck creep or trailer walk). Trailer creep occurs when a trailer separates from the loading dock during loading or unloading operations, typically due to the repetitive forward and backward motion of forklifts entering and exiting the trailer.
Trailer creep is considered one of the most serious hazards at loading docks. When trailer creep occurs, it creates a dangerous gap between the dock leveler and the trailer floor, which can result in forklifts falling through the gap, leading to serious injuries or fatalities. Data from 2002 to 2009 showed that out of 96 fatal truck-loading incidents, 11 casualties were directly attributed to trailer creep.
- Improper or missing wheel chocks or blocks
- Weight and speed of the forklift and its load
- Grade or slope of the driveway where the trailer is parked
- Softness of the trailer’s suspension system
- Lack of connection between the trailer and tractor
Prevention Requirements
OSHA regulations require the use of restraints when loading and unloading trucks and flatbed trailers to prevent this hazard. While wheel chocks have historically been used, modern loading docks often employ vehicle restraint systems (also called dock locks or truck restraints) that mechanically or hydraulically lock the trailer in position during loading operations.
