Telescopic hydraulic cylinders that can lif t loads up to 600mm in a single movement are being introduced to Australia, New Zealand and Papua New Guinea by high-pressure hydraulics specialist, Enerpac.

The RT Series long-stroke multi-stage telescopic cylinders – in capacities from 14-31 tons – are designed for long cylinder strokes in confined spaces. They are particularly suited for extended lif t heights when clearance is limited.

The telescopic cylinders feature a multi-stage rod built from a series of nested steel tubes of progressively small diameter. “The longer stroke length of the telescopic cylinders will save operators time and simplify projects by moving loads a greater distance and eliminating the use of temporary cribbing,” said Enerpac National Sales Manager Darryl Lange.

They also save time and labour and offer WHS benefits by enabling the power and precision of hydraulics to be applied swiftly without the need for multiple setups and plunger extensions required for shorter-stroke types.

Their user- convenience and WHS benefits are further extended by Enerpac’s 700 bar highpressure engineering, which concentrates more lif ting power into smaller cylinders.

RT series’ nitrocarburized surface treatment inside and out provides unparalleled side-load resistance and corrosion protection for safe use in the harshest conditions, such as those encountered in aggressive environments of building and construction, structural and civil engineering, metal processing and fabrication, mining and mineral processing, oil and gas production, bulk handling, manufacturing and infrastructure development and maintenance, including water, waste water and energy utility installation and maintenance work.

Multi-Stage Telescopic Hydraulic Cylinders features include:

• Three percent side load of full capacity.

• Double- or triple-wear bearing support lif ting stages.

• Tilting saddles with five degrees of maximum tilt.

• Lifting eyes for safe handling and positioning.

• Steel cylinder base for maximum strength.

The rugged durability of Enerpac’s telescopic cylinders is complemented by their backing in the field by the national Enerpac sales, service and technical engineering network, which helps avoid downtime, provides optimum use guidance and on-site safety training where required.

Performance of Summit Edition cylinders can be further enhanced by the use of the latest Venturi Valve Technology with ZE and ZU pumps. Return Assisted Electric Pumps with Venturi Valve Technology provide faster retraction speed and improve the productivity of singleacting cylinders.

RT cylinders are also complemented by Enerpac pumping solutions proven throughout Australasia for applications prioritising speed, control, intermittent or heavy duty. Pumping solutions include P series Hand Pumps, XC series Cordless Pumps, XA series Air Driven pumps, ZU4 series portable electric pumps, ZE series Electric Pumps and SFP series Split Flow pumps.
