Product Description

China factory specialises in manufacturing high quality hydraulic systems

Compact design for significant space savings

High load capacity and stability

Flexible power delivery

Telescopic structure: Through the nested multi-stage sleeve design, the contracted length can be shortened to 20%-40% of the single-section cylinder, which is especially suitable for the scenarios with limited installation space (e.g., dump trucks, excavator booms).
Long stroke advantage: the extended stroke can be several times of the contracted length (e.g. 3-6 stages of expansion), realising a working range far beyond that of a single-section cylinder.

Stage by stage force optimisation: Usually the first section (the thickest section) bears the main load, and the subsequent sections are extended as required to ensure that each stage of the cylinder works under reasonable pressure.
Anti-bias load design: some models have built-in guide rings or buffer devices to reduce lateral sway when multiple sections are extended, which is suitable for aerial work (e.g. fire ladder).

Multi-stage synchronised/sequential control: Graduated and precise control can be achieved through hydraulic valves, e.g. segmented lifting of dump truck carriages to avoid sudden shocks.
Bi-directional action: some models support hydraulic actuation to extend and retract to enhance efficiency (e.g. rapid retraction and release of crane booms).

Energy Savings and Efficiency Improvements

Wide range of application suitability

Durability and ease of maintenance

Extension on demand: the ability to extend only a portion of the sections when unloaded reduces the energy consumption of the hydraulic system.
Rapid response: optimised hydraulic circuits allow for extension and retraction in seconds (e.g. emergency deployment of fire ladders).

Industry coverage: construction machinery (excavator, loader boom), transport vehicles (dump truck, rubbish truck lift), aerospace (landing gear retraction), marine (hatch opening/closing) 
Customisation options: the number of knuckles (commonly 2-6 levels), material (high strength steel/chrome-plated rods), and mounting (articulation/flange fixing) can be customised according to requirements.

Enhanced sealing technology: multi-channel seals (e.g., Stirrup seals, Glaser rings) are used to prevent leakage between sleeves at all levels, adapting to high-pressure environments (the working pressure can reach more than 25MPa).
Modular maintenance: damaged single sections can be replaced independently, reducing maintenance costs.
