The Model: HH-3500-1 is a high-efficiency, commercial-grade 12V DC electric tongue jack manufactured by HENGHONG. Engineered specifically as a high-volume baseline for international parts distributors, RV rental fleets, and utility trailer manufacturers, this jack delivering an uncompromising 3500 lbs (1,587 kg) continuous vertical lifting capacity.
Built to seamlessly mount onto standard 3-bolt A-frame trailer couplers, the HH-3500-1 integrates a built-in high-visibility LED work light directly into the housing. This low-maintenance workhorse eliminates manual labor entirely while guaranteeing effortless, safe trailer hitching, leveling, and overnight setup under poor field visibility or severe weather conditions.
In high-frequency commercial deployment and rugged farm environments, trailer components must withstand rough treatment and unexpected voltage spikes. The HENGHONG HH-3500-1 addresses these field challenges by housing its high-torque motor inside a weather-sealed, impact-resistant composite shield. The internal powertrain utilizes a hardened steel worm-gear reduction assembly engineered to draw less than 25 Amps under maximum rated loading, protecting your trailer's electrical fuses and preserving onboard battery health.
The entire vertical column is fabricated from heavy-gauge structural carbon steel and treated with an anti-corrosion, marine-grade Industrial Powder Coating (available in premium White or classic Black finishes). Packaged in robust, stackable logistics cartons (Yellow Box), this SKU is optimized for direct container freight, distribution warehousing, and swift dealership racking.
