Man­power halved and safety in­creased


With the Christ­mas-New Year Main­te­nance Sea­son ap­proach­ing, many op­er­a­tions and en­gi­neer­ing man­agers are seek­ing ways to achieve strip­ping and re­fur­bish­ment of shaft-mounted ma­chin­ery more quickly, safely and ef­fi­ciently.

Such tasks are one of the most com­mon jobs main­te­nance per­son­nel have to fit into the nar­row win­dow of op­por­tu­nity over this pe­riod, when a host of gears, pul­leys and other shaft-mounted com­po­nents must be speed­ily re­moved from static and mo­bile plant, in­clud­ing tracked and wheeled ve­hi­cles, rail and ma­te­ri­als han­dling plant and elec­tric mo­tors and gear­boxes.

One of the lat­est so­lu­tions to such tasks from En­er­pac in Aus­trala­sia is its new range of Sync Grip Pullers, which fea­ture syn­chro­nised move­ment of their lock­ing jaws for si­mul­ta­ne­ous en­gage­ment and op­ti­mised safety. A safety and work­place ben­e­fit is that the pullers will even grip on sur­faces where nor­mal pullers would slip off – for ex­am­ple, on ta­pered bear­ings, says Dar­ryl Lange, En­er­pac Na­tional Sales Man­ager.

The new SG-Se­ries Sync Grip Pullers – in me­chan­i­cal and hy­draulic con­fig­u­ra­tions up to 45 tonnes ca­pac­ity – op­ti­mise safety, sim­plic­ity and speed of re­moval of bear­ings, bush­ings, gears, sleeves, wheels, fly-wheels, sprock­ets and other shaft-mounted items.

“These sim­ple, safe, swift and eas­ily ap­plied tools of­ten mean that one worker can do a job that of­ten re­quires two with other tools,” says Lange. “They do away en­tirely with out­dated heat and im­pact pro­cesses which are not only in­her­ently more haz­ardous, but which can also dam­age valu­able parts and cause fur­ther de­lay in projects where time is al­ready pre­cious.”

For loads up to 20 tonnes, the SGM-Se­ries me­chan­i­cal pullers pro­vide an eco­nom­i­cal and ef­fi­cient op­tion, with all the same rugged high-strength fea­tures as the hy­draulic op­tion. For more com­plex tasks, up to 45 tonnes, the MPS-Se­ries hy­draulic pullers of­fer hy­drauli­cally ap­plied pulling force through a de­tach­able hy­draulic cylin­der, to in­crease pulling ca­pac­ity and re­duce op­er­a­tor fa­tigue.

“Their, smooth, sim­ple and safe op­er­a­tion means that, in­stead of im­pact haz­ards cre­ated by re­moval meth­ods us­ing ham­mers and levers – with risks to both the work­piece and main­te­nance per­son­nel – Sync Grip Pullers draw parts smoothly and pre­cisely with­out the need for heat­ing or pry­ing,” said Lange. “Sync Grip Pullers are the lat­est evo­lu­tion of En­er­pac’s ad­vanced puller tech­nol­ogy. Be­ing able to fa­cil­i­tate si­mul­ta­ne­ous en­gage­ment of each jaw adds an ad­di­tional level of safety and re­li­a­bil­ity to a very com­mon in­dus­trial process.”
