On busy work sites, workers often struggle with heavy steel tailgates, side compartments and service doors. Unexpected dropping of loaded side panels can cause driver injuries, cargo damage or bent expensive hardware. Properly configured gas springs for truck tailgates and side panels can turn these heavy panels into safe, easy one-hand operations - even for older truck fleets.
This guide, based on Land Gas Springs' OEM experience, explains how to design, size and select gas springs for tailgates and side panels on tipper, dump and box trucks, focusing on heavy-duty use, panel layout and safety.
1. Applications of Gas Springs on Work Trucks
Gas springs are widely used on commercial trucks:
- Tailgate gas springs for tipper and dump truck bodies
- Side panel support gas struts
- Rear and side door gas dampers for box trucks
- Gas springs for service bodies and truck covers
- Gas struts for toolbox lids and drawers
The engineering principle is similar to light pickup tailgate supports, but heavy-duty versions provide greater force and more robust hardware.
2. Safety and Ergonomics
- Prevent sudden dropping and injuries, reduce impact on hinges and latches
- Enable smooth, one-hand operation even with gloves
- Lower fatigue and risk of muscle or back injuries for drivers and loaders
3. Sizing: Length, Stroke and Force
- Measure installation distance between fully open and closed positions
- Ensure proper mounting angle and no interference with the chassis or fenders
- Select force based on panel weight, mounting position and quantity
- Use dual gas springs for heavy tailgates
- Test adjustable prototypes before finalizing specs for modifications
4. Damping and Speed Control
Heavy-duty tailgates often need controlled motion:
- Add hydraulic dampers or use integrated damped gas springs
- Avoid slamming or bouncing at the end of travel
- Extend component life and improve operating feel
5. Typical Installations
- Tipper & side panel trucks: Gas springs mounted between panels and pillars
- Dump tailgates: Compatible with bottom and top hinges, with reinforced brackets
- Box & service trucks: Used on side doors, hatches, toolboxes and vehicle covers
