When choosing semi‑trailer landing gear, do not only focus on price. Keep these key points in mind.
First, check load capacity. Distinguish lifting load and static load. For heavy‑duty transport, pick 28‑ton grade to avoid bending and deformation under heavy load.
Second, choose single‑action or synchronized type. Single‑action legs allow separate height adjustment, ideal for construction sites and uneven ground. Synchronized legs work well in flat yards for fast drop‑and‑hook operations.
Third, look for two‑speed gear mechanism. High‑speed for fast extension & retraction; low‑speed for heavy lifting, saving your cranking effort.
Fourth, material and anti‑corrosion treatment. Q345 high‑strength steel plate with electrophoretic and powder‑coated finish, anti‑rust even in coastal humid areas.
Last but not least, confirm mounting hole pattern. Standard universal interface for direct replacement without frame modification.
Right landing gear ensures stable parking when uncoupling, cutting downtime and maintenance cost.
