The 20 K Lift Axle is a heavy-duty auxiliary axle assembly designed for integration into truck or trailer chassis as a lift‐axle (also known as a tag‐axle or supporting axle) that can be raised or lowered on-demand to optimize load distribution, reduce tyre wear, and meet regulatory axle‐load requirements.
Rated Load Capacity: Designed to support up to approximately 20,000 lbs (~9,000 kg) when fully deployed, aiding in improved weight distribution across the vehicle’s axles.
Lift Mechanism: Equipped with hydraulic or air suspension lift/lower controls allowing the axle to be raised when not needed (for lighter loads) and deployed when extra capacity is required.
Suspension & Structure: Built with robust suspension components (leaf springs, air bags or combination), heavy-duty axle beam, sealed hub bearings, and reinforced mounting brackets suitable for repeated heavy use.
Durability & Serviceability: Designed for commercial trucking/trailer operations—heavy gauge steel, corrosion protection (paint/finish), standard service points for hub and brake maintenance.
Regulatory & Efficiency Benefits: By deploying the lift axle when needed, operators can reduce gross axle loads on the drive or steering axles, potentially reduce fines for overload, improve fuel efficiency and tyre wear when the extra axle isn’t required.
Long‐haul or regional trucks/trailers where load varies and the operator wants to optimize axle loads depending on cargo weight and route.
Multi-axle heavy trailers used in transport of goods where additional axle load capacity is sometimes needed to meet bridge or highway load rules.
Recovery or heavy equipment transport vehicles where variable load weights make occasional axle deployment beneficial.
