Key Features:
Working Principle: Composed of 2–5 nested piston stages (customizable per requirement). High-pressure hydraulic oil sequentially drives each piston stage (from largest to smallest) to extend, generating linear thrust. Retraction is achieved through load weight or optional return springs, enabling long-stroke motion in a compact retracted configuration.

Compact & Space-Saving Design: Its retracted length is only 1/3 to 1/5 of the extended stroke (depending on stage count), overcoming stroke limitations of single-stage cylinders in confined installation spaces while maintaining ample travel range.

High Thrust Output: Manufactured with high-strength alloy steel cylinder body, delivering stable thrust from 5 kN to 500 kN (customizable for heavier loads), perfectly suited for demanding industrial applications.

Enhanced Durability: Cylinder body features a yellow anti-corrosion coating (as shown in product image), combined with high-wear-resistant piston seals, providing excellent resistance to rust and wear in harsh environments (e.g., outdoor construction sites, industrial workshops).

Flexible Mounting Options: Equipped with hinge-type lugs at both ends (consistent with product design), enabling direct connection to equipment linkage components, eliminating the need for additional adapters and simplifying installation.

Typical Applications:
Construction Machinery: Telescopic arm actuation in truck cranes, boom lifting for aerial work platforms, and lift adjustment in concrete pump trucks.

Industrial Equipment: Long-stroke table movement in heavy machine tools, material lifting in large assembly lines, and push mechanisms in waste compactors.

Agricultural Machinery: Height adjustment of harvester grain tanks, folding mechanism of large irrigation sprinkler systems, and lift control of agricultural loader arms.
