Truckunder Liftgate

Our truckunder liftgate is concealed under the rear of the vehicle when folded. When deployed and locked, it provides full lifting/lowering function with complete load capacity.

Designed specifically for refrigerated trucks in cold chain logistics.

Installation position avoids interference with loading docks or cold storage platforms, saving operating space.

Advantages

1. Space-Saving Tuck-Under Design

● Folding & Tucking: The dual aluminum platform folds compactly and tucks neatly under the vehicle, preserving full rear access and eliminating the need for extra swing clearance—ideal for tight loading docks and urban delivery routes.
● No Overhang: Unlike cantilever models, it does not protrude when stowed, reducing the risk of damage and improving maneuverability in confined spaces.

2. Synchronized, Low-Effort Operation

● Torsion Spring Assist: The assist torsion spring reduces the force required for manual unfolding/folding, making one-person operation smoother and less strenuous.
● Guide Rail Precision: The round guide rail assembly ensures the platform moves in a controlled, linear path, eliminating wobble and jams common in cantilever designs.

3. High-Performance Hydraulic System (Shared Excellence)

● Consistent Power: The DC motor, gear pump, and manifold valve deliver reliable, leak-free hydraulic pressure for smooth lifting and lowering, just like our cantilever models.
● Durable Cylinders: The lift, door-closing, and push-pull cylinders are engineered for long service life, with multi-layered seals to resist fluid loss and corrosion.

4. Enhanced Safety & Visibility

● Integrated Safety Lights: Built-in safety lights improve visibility during operation, a critical feature for low-light or busy work environments.
● Foot Switch Control: The platform-mounted foot switch allows hands-free operation, reducing the risk of slips and falls compared to cantilever models that rely solely on remote or hand controls.
