Why are projected or cantilevered dock leveler pits required?

The majority of loading dock areas has a level approach as the truck backs into the loading dock bay and contacts the dock bumpers. In some applications the truck backs down a declined approach to get to the loading dock bay. Without making special pit considerations the top of the truck’s trailer could impact the building wall or the closed overhead door causing severe damage before the bottom of the trailer contacts the dock bumpers. In this application it is recommended to extend or project the pit and the dock bumpers forward to ensure the truck contacts the dock bumpers first. As a guideline project the pit 1” forward per every percent of declined approach.

When are dock leveler free standing frames used?

In some loading dock areas floor space is at a premium, in an application like this it is common to install the dock leveler just outside the overhead door in a free standing frame. If there is an existing facility that requires an additional loading dock it is common to research what services (gas, electricity, water, drain etc.) are below the existing poured concrete floor. If there are no services under the slab a pit is constructed, if there is services below the poured concrete floor it is common to use a dock leveler free standing frame as opposed to excavating and re-routing the services.

Can lift trucks be used on dock lifts?

Although manual pallet trucks or power driven pallet trucks are the most common pieces of material handling equipment used on a dock lift some applications call for the use of a lift truck. If using a lift truck on a dock lift there is one very important option to consider. With the dock lift in the lowered closed position the operator drives the lift truck onto the dock lift platform. As soon as the up button is operated an optional automatic hinged hydraulic roll off stop on the dock lift is activated, basically a hinged barrier rises behind the lift truck. When the dock lift is in the raised position the vertical hinged barrier prevents the lift truck from accidentally driving off the back of the dock lift. When the dock lift is lowered to the closed position the hinged barrier automatically lowers, the lift truck then drives off.

What are the most common loading dock product electrical interlocks?

Although there are many combinations available there are 2 very common interlocks specified. 1. Interlocking a vehicle restraint to a hydraulic or air powered dock leveler. This interlock is safety related, the dock leveler will not operate until the truck in position has been secured by the vehicle restraint. The truck secured signal from the vehicle restraint now renders the dock leveler controls operational. 2. Interlocking the overhead door to a hydraulic or air powered dock leveler. This interlock is used to reduce potential damage to the overhead door and improve building security. Before the dock leveler will operate the overhead door must be raised which activates a wall installed limit switch. The activated limit switch now renders the dock leveler controls operational. When the dock leveler is cycled it will not contact the overhead door causing damage to the door and the locking mechanism.
