Core Safety-First Design
Mechanical Self-Locking: Utilizes a screw-driven trapezoidal thread structure to achieve self-locking; once raised, it maintains stable, long-term load-bearing without requiring additional locking components, preventing accidental load slippage.
Heavy-Duty Stability:The base is constructed from high-strength materials (such as Q235 steel) with an enlarged contact area, ensuring stable support even on uneven terrain like grass or gravel roads.
Overload-Resistant Design: Critical load-bearing components feature a built-in strength margin to meet maximum load requirements for fully loaded trailers, eliminating the risk of structural failure.
Lightweight and User-Friendly Design
Force Amplification Mechanism: Combines gear reduction with a screw mechanism, allowing a single user to easily lift loads weighing several tons with minimal manual cranking effort.
Compact, Integrated Layout: Features a streamlined structure free of unnecessary components; it occupies no extra space on the trailer after installation and is highly convenient to stow or carry.
No External Power Required: Operates entirely via a mechanical structure without the need for an external power source, ensuring functionality in off-grid locations-ideal for outdoor camping and long-distance towing.
