External Trailer Landing Gear 75KG, American Semi-Trailer Mechanical Support Leg, Heavy Duty Trailer Lifting Jack

1. Structure & Lightweight Craft
The column is thick rectangular square tube with full welding to guarantee rigidity while optimizing material, only 75KG per unit for easy transport and installation. Side external gearbox enables convenient maintenance; large module gear resists abrasion and impact to avoid damage after long-term lifting.
2. Wide Anti-Slip Base
Integrated widened triangular base with double reinforcing ribs for even stress distribution. Pin hole reserved for anti-slip pad to adapt soft and uneven construction ground; rotatable base slightly adjusts to ground angle automatically.
3. Safe Self-Locking Lifting System
Multi-stage telescopic column provides ample stroke for various ground clearances. Gear self-locking mechanism locks automatically once cranking stops without extra pins for safe parking. Uniform lifting damping ensures smooth operation.
4. Anti-Corrosion Durable Treatment
Sandblasting removes rust and oxide layer; high-temperature electrostatic spray paint firmly adheres to resist rain, mud and saline alkali, no peeling or rust outdoors. High-temperature grease pre-filled on rotary bearings reduces friction and extends service life.
5. Matching Compatibility
