Tianjin Uranus: Leading the Way in Telescopic Cylinder Manufacturing

At Tianjin Uranus, we take pride in our expertise in manufacturing telescopic cylinders. Composed of multiple nested piston cylinders, our telescopic cylinders can achieve multi - stage telescopic motion, featuring a long stroke when extended and a compact size when retracted. They are ideal for applications where large stroke lengths are required but installation space is limited, such as in fire truck ladders, crane booms, and truck body lifting systems. We use high - quality materials and advanced manufacturing techniques to ensure the performance and longevity of our telescopic cylinders.

Why choose us?

Space - Saving Design of Telescopic Cylinders

Our telescopic cylinders stand out for their space - saving design, featuring multiple nested piston tubes for extended stroke and compact retraction. This design is ideal for applications with limited installation space, such as fire truck ladders, crane booms, and truck body lifting. We optimize space utilization without compromising performance.

Multi - Stage Extension Capability

With multi - stage extension capability, our telescopic cylinders deliver precise and smooth motion across various industries. The sequential extension mechanism ensures stable operation even at maximum stroke, providing consistent force output. This capability makes them suitable for demanding applications requiring long - range movement.

High - Strength Construction for Telescopic Cylinders

We construct our telescopic cylinders with high - strength materials to withstand heavy loads and harsh conditions. The robust design resists deformation and wear, ensuring reliable performance in outdoor and industrial environments. This durability translates to reduced maintenance costs and increased equipment uptime for our customers.

Our hydraulic telescoping cylinders are engineered for long-stroke applications where space is limited. The high-pressure design (35 MPa) uses a stepped piston configuration to optimize force output across stages, while the hard chrome-plated piston rods (thickness 25μm) resist corrosion and wear. A flow-divider valve ensures smooth, jerk-free extension, and the internal stop collar prevents metal-to-metal contact at full stroke. These cylinders are used in mobile cranes (70-meter booms), fire rescue vehicles, and industrial material handlers. The lightweight design (aluminum alloy stages for non-corrosive applications) reduces equipment payload, while the modular construction allows field serviceability. All cylinders undergo 1.5x rated pressure testing and 24-hour salt spray exposure. Explore our telescoping cylinder brochure at [https://www.uranustj.com/] or request a custom stroke solution.

Frequently Asked Questions

What is the working principle of a telescopic cylinder?

A telescopic cylinder consists of multiple nested piston cylinders. When hydraulic oil is supplied, the outermost cylinder extends first, followed by the inner cylinders in sequence, achieving a long - stroke extension. During retraction, the process is reversed, and the cylinders retract one by one, resulting in a compact size when retracted.
Mainly used in scenarios where a large stroke is required but the installation space is limited. For example, in fire truck ladders, where they need to extend to high floors for rescue operations; in crane booms for reaching different working radii; and in truck - mounted platforms for lifting and transporting goods.
Compared to ordinary cylinders, telescopic cylinders can achieve a much longer stroke within a limited space. They are also more flexible in terms of installation and can adapt to different working conditions where space is restricted, while still providing sufficient force for the operation.
Yes, the company can provide telescopic cylinders with special requirements, such as customized stroke lengths, high - pressure resistance designs, and special materials for use in harsh environments, to meet the diverse needs of customers in different industries.
