Single Acting Multi Stage Hydraulic Cylinder Long Stroke For Dump Truck

Multi Stage Hydraulic Cylinder Product Description

Our long-stroke single-acting multi-stage hydraulic cylinder is designed specifically for dump trucks. It adopts a multi-stage nested sleeve structure to achieve ultra-long stroke output within an extremely short retraction length. It achieves large-angle tipping and unloading through unidirectional high-pressure oil propulsion. It has advantages such as high load-bearing capacity, compact structure, light weight, easy installation, and reliable durability. It is the core actuator of the dump truck body lifting system.

Our multi-stage single-acting hydraulic cylinders extend the piston rod in one direction using only high-pressure oil, while retraction is achieved by external force. They are simple in structure, low in cost, lightweight, and easy to maintain. They are particularly suitable for engineering machinery and industrial applications that require only unidirectional high thrust and do not require hydraulic drive for return, such as dump truck lifting, hydraulic jacks, snow plows, forklifts, simple lifting equipment, and press clamping.

Runhe Hydraulics specializes in manufacturing hydraulic cylinders, gear pumps, gear motors, and accessories, and can customize products to meet your needs.

We specialize in hydraulics, and only produce the best.

Multi Stage Hydraulic Cylinder Specification

Multi Stage Hydraulic Cylinder Features

1. Compact structure, long stroke: Small volume when retracted, and the extension stroke can reach 2-5 times the cylinder length, suitable for space-constrained applications.
2. Multi-stage nesting: Typically 2-6 stages of cylinder extension and retraction, achieving a large stroke output.
3. Gradually decreasing thrust: The largest stage has the strongest thrust, which decreases with each subsequent stage, matching the high initial lifting force and low subsequent force conditions (such as dump trucks).
4. Mostly single-acting: Extended by hydraulic pressure, retracted by its own weight; double-acting is less common.
5. Complex sealing and high synchronization requirements: Precise sealing and synchronization design are required between multiple stages to avoid jamming.
6. Lightweight and easy to install: Lighter than single-stage cylinders of the same stroke.
7. Wide range of applications: Dump trucks, garbage trucks, aerial work platforms, agricultural machinery, etc.

Multi Stage Hydraulic Cylinder

1. Dump Truck: Used for lifting and unloading the cargo box.
2. Garbage Truck/Compactor Garbage Truck: Features a tilting or compressing mechanism for the cargo box.
3. Agricultural Machinery: Agricultural dump trailers, grain unloading trucks, and harvester unloading devices.
4. Aerial Work Platforms/Landline Lifts: Uses a telescopic boom or platform for lifting.
5. Cranes/Hydraulic Cranes: Features a telescopic boom or outrigger control (mostly double-acting).
6. Others: Fire ladder trucks, mining equipment, port container tippers, material handling equipment, etc.

Multi Stage Hydraulic Cylinder Advantages

1. Compact structure, long stroke: Small size when retracted, providing an extension stroke 2-5 times the cylinder length, saving installation space.
2. Lightweight: Lighter overall weight, reducing the total weight of the equipment and improving mobility.
3. Staged thrust matching: Strong maximum thrust, gradually decreasing in subsequent stages, perfectly suited for lifting conditions requiring high force initially and lower force later (such as dump trucks).
4. Easy installation: No additional guide rails required, simplifying equipment design.
5. Cost and efficiency optimization: More economical and efficient in situations with limited space and long stroke requirements.

Multi Stage Hydraulic Cylinder Working Principle 

Hydraulic oil pushes the largest stage to extend step by step; single-acting stage retracts by its own weight, while double-acting stage retracts by hydraulic pressure.
