Z-Deck Truck Leveler

Improve loading dock operations safely

Optimize your dock efficiency and safety by loading and unloading trailers above the building floor level. This minimizes interferences by the bumpers and building face. It reduces product damage and allows forklift drivers to have a better grade in and out of trailers. The revolutionary Z-Deck trailer lift raises trailer tires with a sloped deck that minimizes the angle of the lifting surface to keep the trailers from rolling away under their own weight. Designed to work with wall mounted vehicle restraints, the Z-Deck trailer lift matches the stroke of the lift cylinders to the vertical travel of a wall mounted restraint to increase the overall safety of the dock system.

•	Increase Productivity Eliminate floor interference by safety lifting trailer beds above dock level for full, unobstructed loading operations.	•	Low-Profile Design 2” Rear section slopes upwards to 8” at apex. No need for a costly in-ground pit.
•	Maximize Safety The unique Z-shaped deck profile keeps tires on the deck and minimizes the slope the tires are supported by. Profile keeps tires angled towards dock to level at maximum raise.	•	Simple Design Robust construction and dual lifting cylinders provide reliability and safety.
•	Full-width Trailer Access Elevate trailers above floor level to service wider trucks with full-width loads.	•	Improved Trailer Alignment Integral Wheel Guides center trailer on docks, minimizing product and door damage.

“Ski-Slope”- the hinging action of a typical truck leveler pivots the front of the ramp and raises the rear causing a negative angle in relation to the dock. The Z-Deck Truck Leveler by Leum Engineering, Inc. is the only truck leveler on the market that can solve this very basic, yet dangerous condition. The mid-level profile slopes back toward the dock when stored creating a much safer condition. Due to the shock loads caused by forklift operations, a vehicle restraint is always safe practice.

The Z-profile also increases the lift of axles that are further away from the dock face with a shorter lifting platform.

Unique “high-lift” hinges at the front of the deck arc towards the dock creating a net vertical lift, minimizing the push away from the dock and again making the dock interface safer.

The integral wheel guides center the trailer to optimize the door openings and minimize product damage. Using the lifting function to position the trailer bed above dock levels
gives the operator full width access to the load and minimize product damage and
increase productivity.
