The Model: HH-3500 Standard is a high-reliability, fleet-grade 12V DC electric tongue jack manufactured by HENGHONG. Engineered as a high-volume, cost-effective baseline for commercial trailer builders, RV fleet operators, and logistics parts distributors, this jack offers an uncompromising 3500 lbs (1,587 kg) dynamic lifting capacity.
Designed to fit all standard three-bolt A-frame trailer couplers, the HH-3500 Standard focuses on mechanical simplification, delivering low-maintenance and long-lasting durability. Equipped with an integrated manual override drive core, it ensures absolute fleet operational uptime even during complete onboard battery failure or zero-voltage conditions.
In commercial rental fleets and agricultural supply chains, complex electronics can often become points of failure when exposed to harsh outdoor elements. The HENGHONG HH-3500 Standard eliminates unnecessary complications by prioritizing robust electromechanical execution. The internal mechanism features a high-efficiency steel worm-gear reduction assembly that minimizes mechanical noise while drawing less than 25 Amps under peak structural loading.
The heavy-wall steel structural housing is finished with an anti-corrosion, marine-grade industrial Powder Coating (available in clean White or textured Black) to resist severe rust, salt-spray flaking, and prolonged UV breakdown. Shipped in high-density, stackable logistics cartons (Yellow Box), this product is optimized for rapid distributor warehousing, direct-to-dealership racking, and streamlined line-assembly operations.
