Product Description
Our Mechanical Suspension Lifting Device revolutionizes trailer height adjustment with an ultra-reliable, maintenance-free design. Engineered for severe-duty applications, this robust system enables instant 6-inch (150mm) ground clearance adjustment without hydraulic or pneumatic components. The patented dual-cam lifting mechanism provides unmatched stability when raising/lowering loaded trailers (up to 36,000 lbs per axle), making it ideal for border crossings, weigh stations, and uneven loading docks.
