Telescopic Hydraulic Cylinders

Long Reach, Short Profile

Engineered to YOUR Application

Telescopic hydraulic cylinders, sometimes called multi-stage cylinders, allow for a long stroke while maintaining a short retracted length. This is achieved with 2 or more nested stages which help to achieve a longer working stroke than a single-stage rod-style actuator is capable of.

RHK’s technical sales and engineering teams have extensive experience designing cylinders from a set of specifications or even a conceptual idea.

Designed and Manufactured to your Requirements

RHK’s sales and engineering team has extensive experience designing cylinders from a set of specifications or even a conceptual idea. Let us engineer a design to your specific application.

Single Acting Telescopic Cylinders

Single Acting Telescopic Cylinders are extended using hydraulic pressure and retracted using an external force, such as gravity.

Double Acting Telescopic Cylinders

Double Acting Telescopic Cylinders use hydraulic pressure to extend AND retract. This design involves additional sealing and internal components feature machined passageways for proper staging. 

Single/Double Acting Combination

Single/Double Acting Combination Cylinders provide a retract force for only a portion of the stroke and gravity retracts the remainder. Allowing a number of stages to remain single acting, maintains simplicity in design and reduces overall cost.

Application Specific Design and Engineering

RHK is a leader in custom manufacturing of all types of hydraulic cylinders. We manufacture single or multi-stage cylinders, single or double acting. All products are engineered to meet safety, material strength, and load capacity guidelines. Additionally, all manufacturing processes are done in-house.

Our engineering and applications team will work closely with you, the customer to understand your specifications, requirements and applications. RHK will create designs, manufacture, inspect and deliver within the timeframe which ensures consistent high-quality cylinders to the marketplace. All cylinders are designed, built and tested as per API standards and follow ISO 9001:2015 standards.

Hydraulic Cylinder Counterbalance Valve manufacturing and design engineering

Valve Integration

Up the Safety Factor

Counterbalance valves provide increased stability and performance in load-holding applications. By integrating valves directly into a cylinder, the risk of external leakage and hose failure is eliminated.

Options Include:

  • Counterbalance valves, Pilot controlled check valves, speed control valves
  • Mid barrel mount, Endcap mount, Rod eye mount
