Semi trailer landing gear (also known as support leg) is an indispensable supporting component mounted on the front of semi trailers. It bears the full front load of the trailer when it is decoupled from the tractor, stabilizes the trailer body during loading, unloading or parking, and prevents tipping or tilting. It is widely fitted on skeleton, lowbed, curtain side, tank and dump semi trailers for port, yard and cross-border logistics.

Our landing gears are fabricated with thickened high-strength steel pipe and heavy-duty gearbox. The manual crank drives the telescopic inner tube to adjust height quickly. Two common speed modes are optional: single speed for heavy static load, and double speed for faster lifting and lowering operations to save labor time. We offer different load capacity grades to match light, medium and heavy haul trailers.

We provide two types of installation structure: single leg and paired double landing gear assembly. Weld-on mounting base is standard design. All gears and shafts are treated for wear resistance, ensuring smooth operation and long service life even under dusty, muddy or frigid working conditions. Anti-rust paint or galvanized surface treatment is available to resist corrosion.

Each landing gear will pass static load test before delivery. Simple operation, strong bearing capacity and easy maintenance make our landing gear a reliable trailer spare part for global customers. Customized color, logo and load rating can be supported as requested.
