What Are Telescopic Hydraulic Cylinders?

Enerpac telescopic cylinders are multi-stage hydraulic actuators that extend in sequential stages, much like a telescope. Each stage, or sleeve, expands from the previous one, allowing the cylinder to achieve a long total stroke while maintaining a short overall collapsed height.

These cylinders are available in both single-acting and double-acting designs:

• Single-acting (spring or load return) cylinders are ideal for vertical lifts.

• Double-acting models offer powered extension and retraction, especially useful in horizontal or inverted applications.

Each Enerpac telescopic cylinder is designed for 10,000 psi (700 bar) and manufactured using high-strength, corrosion-resistant materials to ensure long-term durability and performance.

Where and How Are They Used?

Telescopic cylinders excel in applications that demand high lifting height but minimal retracted length. Common use cases include:

• Bridge lifting and temporary shoring

• Heavy haul and transport vehicle loading

• Industrial equipment deployment in confined spaces

• Silo and vessel jacking

• Railcar and track lifting in tight quarters

• Shipyard and dock support lifts

These cylinders are connected to hydraulic pumps (manual, electric, or air) and controlled using hoses and valves. The sequential extension of stages allows for smooth, controlled elevation even in tight spaces.

Accessories and Supporting Components

To ensure full functionality, Enerpac Telescopic Cylinders are often used alongside:

• Electric or pneumatic high-pressure hydraulic pumps

• Directional control valves (especially for double-acting models)

• Hoses and quick-connect couplers

• Tilt or flat saddles for load alignment

• Base mounting kits for temporary or permanent installations

• Position sensors (on advanced models) to monitor extension stages

Together, these components create a compact yet powerful system for safe and controlled multi-stage lifting.

Industries in the USA That Use Telescopic Cylinders

Enerpac telescopic hydraulic cylinders are found in many sectors where compact solutions are a must:

• Civil Infrastructure & Construction – For bridge lifting, formwork elevation, and beam support

• Transportation & Logistics – Used in loading/unloading heavy machinery or trailers

• Mining & Energy – Ideal for tight underground environments and field-deployed equipment

• Shipbuilding & Maritime – For bulkhead positioning, vessel lifting, and dry dock operations

• Rail Industry – Deployed in railcar jacking and track alignment where access is limited

• Heavy Manufacturing – For lifting assemblies and components that require long travel distance

Their long stroke capability allows teams to lift, adjust, or install large components without multiple setups or stacked equipment.

Why Choose Enerpac Telescopic Cylinders?

Enerpac’s telescopic cylinders are trusted worldwide due to their:

• High strength-to-weight ratio

• Compact retracted height with extended reach

• Precise control over each stage’s movement

• Corrosion-resistant finishes for outdoor durability

• Rugged construction for industrial environments

Backed by Enerpac’s engineering support, service kits, and global availability, these cylinders provide long-term reliability—even under the harshest job site conditions.

Interesting Facts

• Enerpac telescopic cylinders can offer up to five times more stroke than their retracted height.

• They’re often used as part of jack-and-slide systems for modular structure relocation.

• Certain models are designed to operate horizontally, making them ideal for specialized pushing applications.

• Some telescopic systems include load-holding rings or stroke limit indicators for added safety.
