RAM® Premium™ 15K Self-Contained Hydraulic Trailer Jack, Square Tube Bolt-On, 12,000 lb Lift / 15,000 lb Support, 24.2″ Travel, 12V DC, (HJ-15009)

Product Description

Still hand-cranking on heavy loads? Tired of the time it takes and the shoulder pain you feel afterward?

Imagine backing the truck up, thumbing the button, hooking up, and going. Hitching turns into a thirty-second job instead of the part of the day you put off.

Everything is self-contained, so there’s no wet kit to install, no diverter valve, no lines to run — it bolts on and runs off a battery. The foot pad pivots, which matters on gravel or soft ground, where a fixed pad digs in a corner and lets the trailer shift. The motor drives both directions, so retracting is as fast as lifting. The remote locks out so it can’t be bumped while you’re working around the tongue.

Lose power, no problem—you’re not stranded — a hex bit in a standard drill will run the jack up or down. See the maintenance notes below.

Built for horse and livestock trailers, commercial and construction trailers.

Before You Order
This jack needs a power source you’ll have to supply. Not included: a full-size 12V Group 27 deep-cycle RV/marine battery, battery cables, insulating boots, and mounting hardware. Hydraulic hoses are included and pre-attached. Call us at 717-262-6383, and we’ll make sure you have everything before it ships.

Maintenance Notes

• Manual override: use a ¼” hardened hex male drive bit in a standard power drill. Do not use an impact driver or hammer drill — it will damage the motor and pump assembly. On this HJ-15009 model, disconnect the flat copper connector running from the motor to the starter solenoid, then hold the up or down button on the pendant while turning the pump with the drill.
• Do not lubricate the jack tubes. Grease attracts dirt and will affect operation.
• Do not mix hydraulic fluids, and do not use biodegradable fluid. Mixing oils voids the manufacturer’s warranty.
• Bleed the system on first use per the manual. Store the remote pendant in the tow vehicle when not in use.

Need a jack that holds its height over long parking periods? The HJ-15079 adds an integrated counterbalance valve that prevents the jack from drifting down over time — same 12,000 lb lift and 15,000 lb support. We can get it for you. Call 717-262-6383.
