Telescopic Cylinders

TELESCOPIC CYLINDERS

Telescopic cylinders provide a long stroke from a very compact retracted length.HCIC has experience designingtelescopic for a number of industries and applications and can work with you to design a single acting, a single acting/double acting combination, or a double acting design.

Single-Acting Telescopic Cylinders

Single-acting cylinders use hydraulic pressure to extend, and retract due to load from gravity or some other external force.

Hydraulic flow and pressure extends the cylinder

Gravity or some other external force will retract the cylinder

Holds position

Long stroke in a compact closed length

Larger outer diameter than rod cylinders

Less complex design than double acting

Double-Acting Telescopic Cylinders

Double-acting cylinders use hydraulic force for both extension and retraction.

Hydraulic power retracts cylinder as opposed to gravity/force

Retract force is able to pull load

Conventional telescopic cylinders

Both ports located on rod end

Piston seals are typically cast iron rings

Cylinder is not designed to hold load in exact positions (drifting)

Minimum flow required to prevent stalling

Special features can be designed into telescopic cylinders

Both ports on the barrel design avoids moving hoses and wear patterns

Positive piston seals allow cylinder to hold the load and eliminate the minimum flow requirement

Less dead lengths per stage than a conventional double acting telescopic

 

OPTIONAL FEATURES

Up to 5000 PSI working pressure

2 to 5 working sections

Up to 20”barrel diameter

Alternative barrel tube stage coatings available including nitride, chrome over nickel, plasma spray

Stroke lengths up to 480”(40 feet)

Alternative rod materials available including carbon steel, precision honed, hard chrome plated stages.

Optional integrated machined piston design

Steel or ductile internally threaded gland design

Optional end mounts: trunnion, clevis, tang, cross tube, spherical bearing, custom bushing, cross drilled hole
