Truck Stabilizing Jacks Help Improve Dock Area Safety
A common concern of any architectural specifier or building owner is loading dock safety. Loading docks which receive large amounts of traffic are especially prone to accidents and injuries. By supplying your loading dock with the correct safety equipment, you can greatly reduce the risk for accidents at the loading dock, as well as improving overall efficiency. One type of equipment is the trailer jack stand, which, when paired with other safety equipment, increases dock safety significantly.
Preventing Accidents Due to Trailer Creep
One common type of preventable accident-causing occurrence is trailer creep. Trailer creep is caused by fork trucks repeatedly entering and exiting the trailer, slowly causing the trailer to become separated from the dock leveler. If left unchecked, this could cause injuries and even deaths to the forklift operator or other workers. There are several variables that can affect trailer creep, including the weight of the fork truck with its load, suspension softness, type of loading dock crossing such as a dock leveler or dock board, as well as a lack of connection between the trailer and the tractor.
Though historically wheel chocks have been used to prevent this phenomenon, several things must be considered, such as wheel chocks slipping and the necessity of workers walking between trailers to set chocks. Wheel chocks and truck restraints can help reduce the chances of trucks accidentally rolling away during loading and unloading.
Preventing Trailer Upending with Trailer Jack Stands
A more reliable addition to wheel chocks at loading docks is a trailer jack stands stabilizer. They are useful for supporting a trailer’s front end when not connected to the truck at a dock. Truck stabilizing jacks help prevent trailer upending which occurs when a detached trailer tilting its front end down and rear end up, potentially harming any dock workers that are in, around, or crossing into the trailer. OSHA 1910.178(m)(7) requires the uses of chocks and sometimes trailer jacks when trailers are unattached to tractors.
Trailer upending can be caused by the trailer’s landing gear collapsing, often due to rust damage or metal fatigue. By securely supporting the trailer with a trailer jack stand in addition to wheel chocks and even manual or hydraulic truck restraints, the possibility of this type of loading dock accident is greatly reduced.
It is often recommended to use a trailer jack in the front two trailer corners. When a truck backs up to your dock, you have no idea how old it is, and subsequently how old the nose legs are. Over time, nose legs become weaker and weaker. When a forklift driver enters the trailer at full speed and drops the payload at the front of the trailer, there is a chance of the nose legs collapsing and injuring the fork truck operator and anyone else nearby.
Choosing the Correct Trailer Jack for Specific Applications
Several aspects must be considered when choosing a truck jack for your loading dock. Firstly, what kind of portability is required? Jacks with wheels reduce worker strain by eliminating the need to manually carry them. An extremely important consideration is the static and lifting capacity—how heavy is the trailer with the fork truck, payload, and dock workers inside?
Another considerable factor is what type of operating mechanism each trailer jack has. Common options include ratchet beam, hydraulic beam, hand crank, spin top, ratchet, and economy models. Finally, many different models with varying service ranges are available. How many inches must the trailer be raised in order to be level with the loading dock?
In conclusion, by combining various types of equipment, such as truck restraints, trailer jacks, wheel chocks, traffic signal dock lights, loading dock spotlights, and dock barricades, you can help reduce the risk of workplace accidents. Many different types of dock safety equipment is available in order to help you run the most safe and efficient loading dock possible.
