Model: SC-Series
The HENGHONG SC-Series Mechanical Scissor Jacks are engineered to deliver uncompromising stabilization, rapid chassis leveling, and rigid sway elimination for travel trailers, pop-up campers, fifth wheels, and commercial utility platforms. Built by an Intertek-Verified Supplier with 22+ years of manufacturing experience, this product line is designed to replace flimsy aftermarket stabilizing components.
Available in a scalable capacity range—from the high-volume standard 2500 lbs (1,134 kg) class (Model: SC-242500) up to the ultra-heavy-duty 7500 lbs (3,402 kg) fleet-grade configurations—these jacks feature an ultra-low 4-inch collapsed profile that maximizes chassis aerodynamics and ground clearance during transit.
In the coastal RV camping and winter logistics sectors, traditional chassis components degrade rapidly due to severe salt-spray exposure and road grime abrasion. HENGHONG solves this industrial vulnerability by subjecting the entire SC-Series production run to a multi-layer Automotive Black E-Coat (Electrophoretic Coating) finish. This chemical bonding process guarantees 100% surface coverage—including internal threads and scissor linkages—delivering elite rust prevention that far outlasts standard liquid spray paints.
The mechanical actuation relies on a precision-machined, high-tensile threaded drive screw. This design provides smooth extension and self-locking capabilities under peak static loads. Designed with an oversized, widened steel footprint base, the jack minimizes localized ground pressure, preventing sinking and tilting on unstable surfaces like mud, sand, gravel, or wet grass.
