Parker Style Telescopic Cylinder
Parker Type telescopic cylinder is widely use in American markets for front-end tipping trucks.
It has proved its performance and durable in dump and other truck equipements.
Product Description
Parker-style telescopic hydraulic cylinders are designed for applications that require long stroke lengths while maintaining a compact retracted length. The multi-stage design allows the cylinder to extend through several stages to provide the required lifting movement.
HCIC manufactures Parker-style and custom telescopic hydraulic cylinders for dump trailers, dump trucks, mobile equipment and other hydraulic lifting applications.
Manufactured to export standards, our Parker style telescopic cylinders provide reliable performance at competitive cost.
①Parker-Style Design Compatibility: Dimensionally compatible with common Parker telescopic cylinder models.
②Long Stroke in Limited Installation Space: Multiple stages allow the cylinder to achieve a long extension without requiring an equally long installation space.
③Heavy-Duty Construction: Honed tubes, precision-machined stages, and high-strength piston rods.
④Stable & Smooth Operation: Optimized oil flow design ensures controlled extension and retraction.
⑤OEM & Custom Manufacturing Available: Bore, stroke, number of stages, mounting type, and ports customizable.

How Does a Telescopic Hydraulic Cylinder Work?
A telescopic hydraulic cylinder uses multiple nested stages to produce a long stroke from a relatively compact retracted length.
When hydraulic oil enters the cylinder, hydraulic pressure generates force on the piston or internal stage. The stages extend progressively to provide the required lifting movement.
In a single-acting configuration, hydraulic pressure is normally used for extension, while the load or an external mechanical force assists retraction. This type of design is commonly used in dump trucks and dump trailers.
In a double-acting configuration, hydraulic pressure can be used for both extension and retraction.
The number of stages, bore size, stroke, working pressure and mounting configuration should be selected according to the complete hydraulic system and mechanical application.
