RUA hydraulic trailer jack is used to lift and stabilize a trailer, making it easier to hitch, unhitch, and perform maintenance. It uses hydraulic pressure to provide lifting power, requiring less effort than manual jacks. Common applications include adjusting the trailer's height, stabilizing it during storage, and lifting it for tire changes or repairs. Hydraulic jacks come in various types, including single-stage and two-stage models, with some featuring electric operation for convenience.

Production Processes
How We Produce Hydraulic Trailer Jack
Machining
Hydraulic cylinders machined by turning and milling compound centers of Mazac and Dawei, the tolerance and accuracy of each parts will be good and stable.
Cleaning
Each parts of the tie rod hydraulic cylinders, will be cleaned by Ultrasonic cleaner.
Assembling
During production, assemble the hydraulic jack by mounting the cylinder onto the base, connecting the piston rod, attaching the hydraulic pump and hoses, installing seals, and filling the system with hydraulic fluid.
Inspecting
Various precision inspection equipment is applied in the quality control, so we have 100% detection capability and traceability.
Testing
1.The Salty Testing Machine test the chrome plated rod and to see the capacity for the anti-corrosion performance.
2.Making the 72 or 96 hours for the testing, we can make it longer according to customers special requirement.
Painting
1.Painting the undercoat, normally it takes one day to dry.
2.Painting the finish painting.
We have our own standard painting color, and thickness of painting is 40 microns.

Customized Solutions for Your Hydraulic Needs
SINGLE HYDRAULIC TRAILER JACK
To connect a single hydraulic trailer jack with a hydraulic power unit (HPU) pack
1. First, position and mount the hydraulic power unit near the trailer’s frame, ensuring easy access.
2. Next, attach the hydraulic hoses: connect the high-pressure input hose from the HPU’s outlet to the trailer jack’s input port, and the return hose from the jack’s output port back to the HPU.
3. Secure all fittings tightly to avoid leaks and ensure the hoses are properly routed to prevent damage.
4. If the HPU is electrically powered, connect the power unit to the trailer’s electrical system, ensuring correct polarity.
5. Fill the hydraulic fluid reservoir and bleed the system to remove any trapped air. Once everything is connected, test the system by operating the jack, checking for smooth operation and any signs of leaks.
6. Finally, ensure all connections are secure, the jack lifts and lowers the trailer properly, and the hydraulic fluid levels are correct for optimal performance.
DUAL HYDRAULIC JACK AND HOIST CYLINDER
To connect jack cylinders, scissor cylinders, and a hydraulic power unit (HPU), begin by securely mounting the HPU, jack cylinders, and scissor cylinders in their respective locations on the trailer, lifting platform, or equipment.
1. Connect the high-pressure outlet from the HPU to the inlet ports of both the jack cylinders and scissor cylinders using high-pressure hydraulic hoses.
2. Similarly, connect the return hoses from the return ports of the cylinders back to the return port on the HPU to complete the circuit.
3. Depending on the system, you may need a manifold valve or distribution block to control and divide the fluid flow between the jack and scissor cylinders.
4. After ensuring all hoses are securely attached, connect the control valves to regulate the movement of the cylinders.
5. Finally, fill the HPU with the appropriate hydraulic fluid, check for leaks, and test the system to ensure both the jack cylinders and scissor cylinders are functioning properly for lifting and extension.
FAQ
FAQ
A: Mount type, pls tell us how you need to install it on your device.
A: Some assembly is required when setting up the jack, such as mounting the base, connecting the hydraulic pump, and securing hoses. However, the jack is typically pre-assembled for ease of installation.
