|---|---|
This hydraulic power units for operating single acting hydraulic cylinders. Ideal for many applications including dump trailers, flatbed dumps, forklift stackers, lift gates, pallet trucks, aerial lifts, auxiliary power and many other applications. 12 Volt DC solenoid release valve with check valve for directional control of single acting cylinder. Built-in check and adjustable main relief valve.
5-8 second ultra-fast positioning (1.4 GPM) : The flow rate is at the fast response level in mobile hydraulics . It can instantly lift the dump truck bed or logistics tailgate into position within seconds, greatly reducing the waiting time for commercial loading and unloading.
10-ton class powerful burst (3000 PSI) : Pure heavy industrial-grade high pressure, with just a lifting cylinder the size of a regular thumb, it can lift a fully loaded truck bed carrying construction debris, asphalt, and timber, with extremely powerful force.
50% reduction in power consumption (single-acting) : Adopts a "power-driven lifting, gravity-driven descent" design [1.1.4, Q2]. The motor operates when lifting and remains completely silent and does not consume any electricity when lowering [1.1.4, Q2]. It saves half the power compared to a dual-acting system, making it a lifesaver for trucks with single batteries.
Minimalist Structure with No Internal Leakage (Fully Integrated) : By eliminating the reciprocating multi-way valve, the oil and electrical circuits are significantly simplified, minimizing the failure rate. The motor, pump, valve, and built-in adjustable relief valve are highly integrated into one unit, automatically releasing pressure in case of cylinder blockage or overload, ensuring no pipe bursts.
Extremely Compact and Easy to Hide (SAE Interface) : Its small size makes it ideal for fitting into a metal toolbox on the side of a truck or under the chassis of a pickup truck. The entire vehicle is equipped with SAE O-ring high-pressure sealed interfaces , ensuring zero oil leaks and zero maintenance, even under years of vehicle vibration.

Applications
Heavy-duty dump trailers : These are primarily used in construction/agricultural dump trailers with a size of 7x14 feet or larger. Their powerful 1.4 GPM flow rate allows the several-ton dump bed to rise rapidly in 5-7 seconds , and after unloading, the bed smoothly and automatically returns to its original position under the pressure of several tons of gravity.
Flatbed Dump Trucks : Heavy-duty lifting mechanisms installed under the flatbed truck chassis. The rated high pressure of 3000 PSI allows for the use of smaller hydraulic cylinders, enabling large-tonnage dumping within a compact chassis space.
Semi-electric forklift stackers : These are mobile stackers used in warehouses where there are no AC power outlets. Driven by a 12V battery, this unit rapidly lifts entire pallets (1-2 tons) of weight to high-level racks at a high efficiency flow rate of 1.4 GPM. Lowering the forklift relies entirely on the weight of the goods themselves, consuming no battery power and significantly extending the forklift's single-charge endurance .
Hydraulic pallet trucks and liftgates : Electric hydraulic tailgates at the rear of commercial vehicles or vans.
Mobile scissor lifts : widely used mobile lifting platforms for factory maintenance and high-altitude pipeline installation. The platform requires 3000 PSI to overcome pure shear force when rising, and when descending, it releases the solenoid valve and relies on the self-weight of the platform's mechanical structure to fall at a uniform speed [Q2].
Car Lifts (single/double column) : Temporary or mobile light-duty car repair lifts.
Heavy industrial loading ramps/dock levelers : hydraulically movable transition ramps connecting warehouse platforms and truck cargo boxes.
Portable Hydraulic Equipment : Heavy-duty machinery (such as a wood splitter for cutting hardwood) driven by a 12V portable battery for field operations. 1.4 GPM can ensure a relatively fast reciprocating stroke cycle speed.
Vehicle-mounted auxiliary power units (Auxiliary Power Units) : These serve as "external or backup emergency power" on medium and large-sized construction machinery. When the vehicle's main engine stalls or the main hydraulic pump stops, the 12V single-acting pump can be activated with a single button, using unidirectional high pressure to forcibly retract the aerial work arm or boom, ensuring the safe evacuation of personnel
Power Units are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Answer : It cannot be directly driven. A single-acting unit has only one oil outlet, making bidirectional strong push and pull impossible.
Analysis : A single-acting power unit can only supply oil to the hydraulic cylinder through one high-pressure oil pipe (power rise).
If you force it onto a double-acting cylinder (with both A and B ports), you can only extend the hydraulic cylinder in one direction. When the "lower" button is pressed, there is no reverse high-pressure oil injection into the hydraulic cylinder, preventing it from being pulled back forcefully.
Solution : If you absolutely must use it to drive a double-acting cylinder, you must connect a manual or electronically controlled three-position four-way directional valve to the outlet port, and connect a hose to the return port (T port) of the directional valve to return it to the oil tank. This is extremely cumbersome, so for double-acting hydraulic cylinders, please be sure to purchase a double-acting power unit directly .
Answer : No, this is the standard operating mode of a single-acting system. It's correct that the motor doesn't turn during descent.
Analysis : The core concept of a single-acting system is "Power Up / Gravity Down" .
During the ascent : The 12V motor rotates at high speed to drive the gear pump, pumping out 3000 PSI high-pressure oil to lift the heavy object.
During descent : The system requires no hydraulic pressure from the motor . When the "Descent" button is pressed, the internal circuitry of the handle supplies power only to the coil of the unload valve on the valve body , opening the valve core . At this time, the enormous weight of the carriage or cargo forces the oil in the hydraulic cylinder back into the tank, much like squeezing a syringe . Therefore, it is perfectly normal for the motor to remain stationary and completely silent during descent.
Answer : A heavy single battery can fully power it, but the vehicle must be running during operation, and the requirements for the cables are extremely high.
Analysis :
Battery and alternator : Since 1.4 GPM is a relatively fast flow rate, under full load at 3000 PSI (e.g., heavy-duty models from Bucher or Concentric), the instantaneous operating current can reach 210A to 260A . A standard car starter battery (12V, 70Ah or higher recommended, CCA 650+) can handle this. However, the truck engine must remain running during operation , requiring the onboard alternator to provide continuous power; otherwise, the battery could easily be drained and rendered unusable.
Key wiring requirements : Heavy-duty pure copper cables of 2 AWG (approximately 35 square millimeters) or even 0 AWG must be used , and the shorter the connection, the better. A 250A high-current DC circuit breaker (fuse) must also be installed at the positive terminal of the battery to prevent short circuits and potential fires.
Answer : This is usually caused by dirt stuck inside the "check valve" or wear (internal leakage) in the solenoid valve core.
Analysis : When the motor stops running, the hydraulic oil can be locked in the cylinder and not return, which is entirely due to the mechanical check valve or the valve core of the solenoid release valve inside the valve block blocking the return oil path.
If the hydraulic oil is too dirty (containing metal shavings or sand), the dirty particles will get stuck on the steel ball or valve core of the check valve, leaving a tiny gap.
Under the immense pressure of a vehicle weighing several tons, hydraulic oil will slowly "leak" back into the oil tank through this gap, causing the truck bed to automatically sink .
Solution : Clean or replace the hydraulic oil, remove the solenoid valve core, clean the inside with a cleaning agent and blow it clean with an air gun before reinstalling.
Answer : First, refueling must be done when the truck bed is fully lowered (hydraulic cylinder fully retracted); second, strictly adhere to the intermittent work schedule to prevent the oil from overheating.
Analysis :
Hydraulic oil level : When the single-acting cylinder extends, it draws in most of the hydraulic oil from the tank; when the truck bed lowers, this oil returns to the tank. Therefore, oil must be added only when the truck bed is fully lowered (without oil in the hydraulic cylinder) , filling the tank to 80% (Max line). If the order is reversed, and the tank is filled while the truck bed is raised, the excess oil will violently gush out from the breather valve at the top of the tank once the truck bed is lowered.
Heat dissipation limit : 1.4 GPM flow rate is relatively high, while the capacity of a small oil tank (e.g., 3-4 quarts) is limited. Continuous high-frequency operation at 3000 PSI high pressure can easily cause the oil to heat up rapidly. Please strictly adhere to the intermittent duty cycle (S3 5%-10%) . A single continuous lift should not exceed 45 seconds to 1 minute. After the operation is completed, allow the motor and oil to cool down.
