Engineering multi-stage hydraulic solutions for heavy-duty lifting in compact spaces. Reliable power, precision extension, and long-cycle durability.
When your application requires a long stroke but has limited mounting space, the telescopic hydraulic cylinder is the definitive solution. Also known as multi-stage cylinders, these specialized components consist of a series of nested tubular stages that extend sequentially, providing an impressive reach while maintaining a compact retracted length.
Our telescopic hydraulic cylinders are engineered for high-intensity industries, including construction, mining, and waste management. Specifically designed for dump trucks, trailers, and specialized lifting platforms, these cylinders ensure smooth multi-stage expansion and retraction. By utilizing premium-grade seamless steel tubing and advanced sealing technology, we provide cylinders that handle heavy lateral loads and extreme environmental conditions without compromising safety or performance.
Delivers an exceptionally long stroke-to-retracted-length ratio, ideal for equipment with tight installation envelopes.
Each stage is precision-ground and hard-chrome plated to resist corrosion, reduce friction, and extend seal life in harsh outdoor environments.
Manufactured from high-tensile ST52 or 4140 seamless steel tubes, ensuring structural integrity under maximum load capacities.
Yagang hydraulic cylinders ensure precision motion control for automated production lines. They address the need for reliable, low-maintenance actuation in packaging, handling, and assembly systems, minimizing downtime in continuous operations.
For high-speed, repetitive cycles in CNC and stamping equipment, Yagang hydraulic cylinders provide exceptional accuracy and rigidity. They are engineered to combat wear and maintain positioning precision over long service life.
As the core power component, Yagang hydraulic cylinders deliver consistent, high-force output for molding and forging. They are built to withstand extreme pressure spikes and ensure stable platen movement, crucial for product quality.
In high-heat, high-shock mill environments, Yagang’s heavy-duty hydraulic cylinders offer robust performance for rolling and handling. Their design focuses on heat resistance and structural integrity to withstand punishing conditions.
Subjected to extreme abrasion and shock loads in crushers and kilns, Yagang hydraulic cylinders are built for toughness. Their robust design prioritizes seal protection and piston rod strength to maximize uptime in the harshest environments.
Our process is built to ensure clarity, efficiency, and full client satisfaction, solidifying our role as your reliable hydraulic partner.
Our technical team assists you in selecting the precise standard cylinder model that meets your required bore, stroke, mounting style, and pressure ratings, ensuring optimal fit and function for your machinery.
Utilizing ISO-compliant quality systems, we manufacture your standard cylinders. Every unit undergoes rigorous in-house testing, including static pressure hold tests and dynamic cycle tests, exceeding industry requirements.
We manage efficient packaging and logistics, providing fast and secure shipping globally. Our focus on rapid delivery minimizes your downtime and accelerates project timelines.
We offer comprehensive technical documentation and readily available remote support for troubleshooting and maintenance guidance, ensuring sustained peak performance throughout the cylinder’s lifespan.
We offer two primary configurations: Single-Acting (extension by hydraulic pressure, retraction by gravity or external force) and Double-Acting (hydraulic pressure controls both extension and retraction). Single-acting models are most common in dump truck applications, while double-acting models are used where precise control of the retraction stroke is required.
Capacity is determined by the effective area of the smallest stage (the final sleeve) and the operating pressure of your system. It is crucial to ensure that the smallest stage can handle the maximum load at the end of the stroke to avoid structural bending or seal failure.
Yes. As a specialized manufacturer, we can customize the number of stages, stroke lengths, mounting types (such as trunnion, pin-eye, or cross-tube), and porting options to match your specific machinery requirements.
Every telescopic hydraulic cylinder undergoes a 100% high-pressure leak test and a full-cycle functionality test before leaving the factory. We strictly adhere to ISO 9001 standards and can provide material certificates and pressure test reports upon request.
Regularly inspect the chrome surfaces for debris or damage, ensure the hydraulic oil is filtered to ISO standards, and grease the mounting points frequently. Keeping the fluid clean is the most effective way to prevent internal scoring of the stages.
