Vertical tailboard power unit

1、 Product Overview

This product is a specialized DC hydraulic power unit for the lifting tailboard of box trucks and logistics vehicles. It integrates a DC motor, electromagnetic reversing valve, fuel tank, emergency pressure relief, and safety protection. It is designed specifically for the 12V/24V DC power supply of vehicles, providing lifting and flipping power for truck loading and unloading tailboards. The structure is enclosed and protected, and is suitable for various types of light trucks and box transport vehicle tailboard modification and original factory matching.

2、 Core component analysis

DC drive motor

Vehicle specific permanent magnet DC motor, available in two voltage specifications of 12V/24V, with high torque output and fast start-up response; Copper terminal blocks are resistant to high currents, suitable for car battery power supply, and have stable starting in low temperature environments.

Electromagnetic hydraulic valve group

Integrated lifting and flipping electromagnetic control valves, electrically controlled automatic direction change, can achieve one click control of tailboard lifting, falling, and flipping; Built in overflow pressure regulating valve, adjustable system maximum pressure, overload automatic pressure relief protection, preventing oil cylinder bursting.

Closed sheet metal fuel tank assembly

The integrated black spray painted sheet metal box has both oil storage and overall protection functions, dust and water resistance, and reduces erosion from road sediment and rainwater; Reserved installation holes in the box body for easy assembly of the entire vehicle; The red knob at the top is an emergency manual pressure relief valve, which can be manually lowered when the vehicle is powered off.

Safety electrical accessories

The transparent shell fuse holder is equipped with an overload fuse, which automatically cuts off power in case of short circuit or overcurrent, protecting the motor and onboard circuit; The side is equipped with a limit micro switch, which can automatically stop and lift in conjunction with the tail plate travel, improving loading and unloading safety.

3、 Core product advantages

✅  Vehicle specific DC design

Suitable for truck battery 12V/24V power supply, no need for external AC power, logistics transportation, outdoor loading and unloading scenes are not limited by the site.

✅  Fully enclosed protective box

The sheet metal shell wraps the internal oil circuit and motor, which is rainproof, mud proof, and anti bumpy, suitable for complex driving conditions of trucks, and extends the service life of internal components.

✅  Double safety pressure relief protection

Electric overflow overload protection+manual emergency pressure relief knob, can safely lower the tailboard in both power-off and fault states, eliminating the risk of cargo hanging in the air.

✅  Compact integration

The motor, valve block, oil tank, and electrical components are integrated into a single assembly with a compact size. The side of the tailboard column is directly fixed, and installation and wiring are simple.

✅  Sealed and durable without leakage

The valve block is precision machined with oil resistant rubber seals, which are resistant to vehicle vibration and have no oil leakage under long-term high and low temperature conditions, reducing maintenance frequency.
