Electric trailer landing leg is an intelligent electric drive support accessory designed for modern semi-trailers, favored by cross-border logistics companies and long-distance transport fleets for its fully automatic lifting function. This electric trailer outrigger leg replaces traditional manual cranking motors, equipped with high-torque low-speed electric motors to drive the internal transmission structure, realizing one-button lifting and lowering without physical labor. The matched built-in storage battery and wired remote control make operation convenient even when the tractor power supply is disconnected, and dual-speed mode is available: fast speed for empty trailer adjustment and slow stable speed for fully loaded heavy vehicles. The paired electric support leg reaches a rated load of 28 tons and static bearing capacity of 80 tons, with 480mm adjustable stroke to cope with uneven yard ground and different tractor heights, reducing chassis torsion risks during parking. The leg body is made of thick seamless hot-rolled steel tubes and ductile iron gears, with sandblasting anti-rust coating and multi-layer rubber waterproof rings to prevent corrosion in rainy and salt fog areas. The universal backboard fits most trailer frames, and both linkage and single-side control modes are optional according to customer demands. Most buyers ask about the durability of the motor; we adopt waterproof dustproof sealed motors with overload self-protection function, automatically cutting off power when stuck to avoid burnout, and worn motors and gears can be replaced independently to lower maintenance costs. OEM customization including customized stroke, zinc plating treatment and exclusive logos is supported, requiring at least 50 sets for personalized orders. During packaging, each electric trailer outrigger leg is wrapped with moisture-proof plastic film and fixed on solid wooden pallets to avoid extrusion damage during sea and land transportation, and goods can be delivered within 7 to 15 days after deposit confirmation with complete factory inspection certificates attached. Inferior electric legs on the market often use thin steel pipes and low-power motors that stall easily under heavy load, while our electric landing leg uses thickened raw materials and reinforced transmission components, capable of stable operation after thousands of lifting cycles, perfect for transport teams pursuing labor-saving and efficient operation.
