HCHJ-12KWP is a double-action hydraulic trailer jack with an integrated power unit, 2-inch bore, 20-inch stroke, SAE6 port and 12T catalog load capacity.
Trailer jacks are easy to overlook until the trailer is loaded, the ground is uneven or the manual handle becomes a daily source of work. For those applications, a hydraulic jack can make front-end support and lifting easier to control.
The HCHJ-12KWP is listed in the HCIC-2026 catalog as a double-action hydraulic jack with power unit. The catalog table gives it a 2-inch bore, 1-inch rod, 20-inch stroke, 30-inch length, SAE6 port, 12T load capacity and 3,000 psi working pressure.
This is a different product from a standalone dump-trailer HPU. HCHJ-12KWP combines the jack function with a power-unit configuration, so the buyer should review the jack mounting, trailer structure, hydraulic connections and electrical arrangement together.

The load capacity and pressure shown above are catalog values. They do not replace a review of the trailer frame, foot support, mounting hardware, ground condition, center of gravity or the actual operating sequence.
A double-action jack is designed for hydraulic movement in both directions. That can be useful when the trailer needs powered extension and retraction rather than a powered lift followed by a separate return method.
The practical benefit depends on the complete installation. The jack must be mounted so that the trailer frame can carry the applied load, the rod remains within its intended path and the foot or support surface stays stable. A power unit cannot correct a weak bracket, a misaligned mount or an unstable base.
The HCHJ-12KWP should therefore be treated as a trailer-system component, not just a cylinder with a motor attached. The hydraulic circuit, power supply and structural support all need to match the job.
The catalog positions the hydraulic jack range for dump trailers and other trailer applications, including livestock, horse, car, cargo and flatbed gooseneck trailers. The best match depends on the trailer design and the required support or lifting movement.
Before choosing HCHJ-12KWP, confirm whether the project needs:
These checks help separate a genuine fit from a product that only appears similar in a search result.
Send the jack mounting drawing or clear photographs of the trailer bracket. The support structure must be reviewed for the expected load path, weld condition, fasteners and available clearance around the moving rod and foot.
A hydraulic jack can move the trailer, but it still needs a stable support surface. If the trailer operates on gravel, sloped ground or changing work sites, discuss the foot-pad arrangement and the way the load is transferred into the ground.
Confirm the hose route, port orientation, control switch or remote arrangement, battery supply and protection devices. Keep the cable and hose path away from sharp edges, heat and moving suspension or frame parts.
Leave enough room to inspect the power unit, hose fittings, rod surface and mounting hardware. A tight installation may look efficient during assembly and become inconvenient during routine service.
For a useful quotation, send:
- Trailer type and loaded operating condition
- Current jack model, if this is a replacement
- Mounting drawing or photos with key dimensions
- Required stroke and available length
- Hydraulic port and hose details
- Battery voltage and control preference
- Ground conditions and support-foot requirements
- Expected operating frequency
If the jack is being replaced, include photos of the mounting bracket, wiring, hoses and the surrounding trailer frame. Those details often reveal fit issues before the order is released.
Send the trailer type, mounting photos, required stroke, battery/control details and operating conditions when requesting a quotation. HCIC can then review whether the HCHJ-12KWP configuration fits the trailer structure and the intended powered movement.
