Support Oil Cylinder
Product description:

A support oil cylinder, also known as a hydraulic support cylinder or outrigger cylinder, is a critical hydraulic component designed to provide stable mechanical support and balance for heavy machinery and vehicles. It helps maintain equilibrium, prevents tipping, and absorbs external loads during operation.

Commonly installed on cranes, excavators, concrete pumps, aerial platforms, drilling rigs, and lifting equipment, the support oil cylinder ensures safety and stability when machinery is in use. Its precise hydraulic control and high load-bearing capacity make it essential in construction, mining, transportation, and industrial applications.

hydraulic cylinders are actuators that convert hydraulic energy into linear mechanical force. They have a compact structure, high output force, and smooth operation. They are the core components for performing actions such as pushing, pulling, lifting, and pressing in various mechanical and industrial systems, and are widely used in construction machinery, metallurgy, mining, shipping, and other fields.

Structure and Working Principle

The hydraulic support cylinder consists of several key components:

• Cylinder barrel – precision honed for high strength and smooth hydraulic operation.
• Piston and piston rod – convert hydraulic pressure into linear mechanical force.
• Sealing system – prevents oil leakage and ensures stable operation under high pressure.
• End caps and mounts – allow secure connection to machinery frames or outriggers.
• The cylinder operates on a double-acting or single-acting hydraulic principle. When pressurized oil is supplied to one side of the piston, it extends the rod to deploy support legs or stabilizers. When the pressure is released, the cylinder retracts to its original position. This reliable mechanism enables quick, safe, and powerful deployment of supports, even under extreme load conditions.

Materials and Manufacturing Process

The support oil cylinder body is made from high-strength alloy steel or seamless Precision steel tubes, ensuring superior durability, impact resistance, and pressure tolerance. The piston rod is hard chrome plated or QPQ nitrided to resist wear, corrosion, and pitting.

All components are CNC-machined for accuracy, and robotic welding is applied to enhance structural integrity. The sealing system, using premium brands like Parker, Hallite, or NOK, guarantees excellent oil retention and minimal leakage even under heavy-duty applications.

Every cylinder is designed and manufactured under strict ISO, DIN, and CE quality standards to meet global hydraulic equipment requirements.

Applications:

The hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy. It is the core executive component in the hydraulic system. The hydraulic cylinder uses hydraulic oil to drive the piston to move, converting hydraulic energy into linear reciprocating motion. When the hydraulic oil enters the cylinder barrel, it pushes the piston rod to extend or retract, completing the predetermined action. The direction and speed of its movement are regulated by the hydraulic control system. The hydraulic cylinder consists of a cylinder barrel, cylinder cover, piston and piston rod, sealing device, and buffering device. According to its structure, it can be classified as piston type, plunger type, multi-stage telescopic sleeve type, and gear rack type. Hydraulic cylinders are widely used in machine tools, construction machinery, vehicles, and other fields, featuring a simple structure and smooth movement.

The Support Oil Cylinder is an essential part of many types of mobile and stationary hydraulic equipment, including:

• Truck-mounted cranes and mobile cranes – stabilizes the vehicle during lifting operations.
• Concrete pumps and placing booms – supports the machine for balance during pumping.
• Excavators and drilling rigs – provides stability on uneven ground.
• Aerial work platforms – ensures safety and prevents tilting during high-altitude operations.
• Construction and mining vehicles – supports the chassis during heavy-duty work.
• Agricultural machinery and trailers – maintains balance during loading and unloading.
• In each application, the support oil cylinder provides secure positioning, load distribution, and enhanced operational safety.

Quality Control and Testing

Every cylinder undergoes strict inspection and hydraulic testing before delivery. Quality assurance includes:

Pressure and leakage testing under rated loads

Dimensional accuracy verification

Coating adhesion and corrosion resistance testing

Fatigue and endurance testing for long-term reliability

All products comply with ISO, DIN, and CE standards, guaranteeing consistent performance and safety in demanding industrial environments.
