Project Info
Project Name: Dump Trailer Hydraulic Power Unit & Hydraulic Cylinders
Client Industry: Trailer Manufacturing / Hydraulic Equipment / Construction & Transportation Equipment
Requirement：
- Provide a complete hydraulic solution for dump trailers, including Hydraulic Power Unit (HPU) and hydraulic cylinders.
- Ensure compatibility with 12V DC / 24V DC electrical systems.
- Match flow rate to achieve the required lifting/lowering speed.
- Match pressure rating to ensure stable lifting under full load conditions.
Project Overview
In modern transport operations, dump trailers are widely used for moving sand, gravel, demolition debris, agricultural products, and industrial waste. The efficiency of unloading directly affects daily productivity and operating cost.
A dump trailer hydraulic system mainly relies on two critical components:
1) Hydraulic Cylinder – converts hydraulic pressure into linear force to raise and lower the trailer bed.
2) Hydraulic Power Pack – provides pressurized hydraulic oil flow through motor, pump, reservoir, and control valves.
In this project, the customer needed a robust and compact hydraulic solution for medium-to-heavy duty dump trailers, with consistent lifting performance under frequent loading cycles
Hydraulic Solution For Dump Trailer
A. Dump Trailer Hydraulic Cylinder Selection
In Dump Trailer Hydraulic Cylinder Selection, common options include telescopic hydraulic cylinders, hydraulic jacks, and complete dump trailer lifting hoist systems. Telescopic cylinders are ideal for long stroke and high dump angles, hydraulic jacks suit compact and light-duty applications, and hoist systems provide an integrated lifting structure for stable, heavy-duty tipping performance.
Telescopic Hydraulic Cylinder Solution
Our telescopic cylinder solution is designed for smooth extension, stable return, and complete material discharge, making it ideal for standard and heavy-duty dump trailers.
- Type: Single-acting telescopic cylinder (long stroke with compact retracted length)
- Material: High-strength honed tube + hard chrome-plated rod
- Sealing: Heavy-duty seal kit with upgraded dust/wiper design
- Customization: Bore/stroke matched to bed length, payload, and tipping angle
- Mounting: Reinforced pin/trunnion areas for better load distribution

Hydraulic Jack Cylinder Solution
Best for: compact installation space, light-to-medium duty trailers.
- Simple structure, easy installation, cost-effective
- Works with DC hydraulic power pack for reliable up/down control

Hydraulic Scissor Hoist Kit Solution
Best for: frequent cycles, heavy load, high stability requirements.
Our scissor hoist kit provides:
- Better load distribution than direct-lift single-cylinder design
- Smoother lifting motion and improved structural stability
- Long service life under repeated tipping operations
B. Dump Trailer Hydraulic Power Packs
Power Pack Type: DC hydraulic power pack (12V/24V) for mobile trailer application, with optional AC station for fixed-site scenarios.
For mobile dumping applications, the dump trailer hydraulic power pack uses a DC hydraulic power pack design with a high-torque motor and a double acting hydraulic pump for fast pressure build-up, stable lifting/lowering, and reliable load control. With integrated safety valves, compact tank design, and optional wired or wireless control, it delivers efficient cycle times, safer operation, and lower failure risk.
| Model | Volt | Power | Speed | Displacement | Pressure | Tank | Solenoid Valve Volt |
| HPU-1.6-D12-2.1-16-HS/5-Y3-G3/8 | DC12V | 1.6kW | 2500RPM | 2.1CC/REV | 16MPa | 5L | DC12V |
| HPU-2.2-D24-2.6-20-HS/6-Y3-G3/8 | DC24V | 2.2kW | 2700RPM | 2.6CC/REV | 20MPa | 6L | DC24V |
Summary
This project delivers a complete dump trailer hydraulic solution by integrating the right hydraulic cylinder with a properly matched DC hydraulic power unit (12V/24V).
Based on trailer structure, payload, and duty cycle, the solution provides three cylinder options—telescopic cylinder, hydraulic jack cylinder, and scissor hoist kit—to cover compact, standard, and heavy-duty tipping applications.
On the power side, the selected hydraulic power packs are configured for suitable flow rate, pressure capacity, and control stability, ensuring reliable lifting/lowering speed and safe full-load performance under frequent operating cycles.
