Product Description

Three-stage Telescopic Cylinder: Long Stroke Power in a Compact Body

Three-stage Telescopic Cylinder is specially engineered to achieve long extension distances while maintaining a minimal retracted length. This is made possible by the multi-stage design, where each cylinder stage slides out in sequence, maximizing stroke while minimizing space requirements.

This telescopic hydraulic cylinder is commonly used in vertical lift systems, dump trailers, agricultural tippers, and refuse trucks. Its reliable performance in both single and double-acting modes makes it a core component in demanding mobile hydraulic systems.

As a Hydraulic Telescoping Ram, it ensures smooth extension and retraction even under high loads. Whether you need vertical lift, horizontal push, or variable angle movement, this 3-stage design is built for efficiency, stability, and durability.

FAQ

FAQs

What makes a three-stage telescopic cylinder different from standard cylinders?

Unlike traditional cylinders with a single stroke, the three-stage telescopic cylinder uses three nested stages to achieve much longer extension in a smaller footprint when retracted.
Can this 3stage hydraulic cylinder handle both push and pull motions?

Yes. Double-acting models apply hydraulic pressure for both extension and retraction, while single-acting versions use gravity or load weight for return.
What kind of maintenance does a telescopic hydraulic cylinder require?

Regular inspection of seals, stage movement, hydraulic oil condition, and cleaning of external surfaces to avoid debris damage during retraction.
Can I use a three-stage cylinder in horizontal applications?

Absolutely. While vertical use is common, many Hydraulic Telescoping Rams are used in horizontal or angled systems with proper support and flow control.
Is customization available for stroke, bore, and mounting?

Yes. Stroke length, bore diameter, mounting style, pressure rating, and port configurations can all be tailored to suit specific equipment and application requirements.
