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.
