Pre­ci­sion and safety for heavy lifts sees de­liv­ery of EVO Syn­chro­nous Lift­ing Sys­tem to Tri­dent Aus­tralia

DEMM Engineering & Manufacturing - - PRODUCT WATCH - De­tails: Neville Stu­art neville@en­er­

Tri­dent Aus­tralia’s WA branch has ex­panded its range of hy­draulic tech­nol­ogy to in­clude the lat­est En­er­pac EVO syn­chro­nous lift­ing sys­tem, which pro­vides ac­cu­racy, safety and pro­duc­tiv­ity ben­e­fits for pre­ci­sion lift­ing of heavy ma­chin­ery, some­times ex­ceed­ing sev­eral thou­sand tons.

The sys­tem, which con­trols up to 12 lift points per unit (and up to four units can be ‘daisy chained’ to­gether to lift up to 48 points from a sin­gle mas­ter con­trol unit) del­i­cately lifts, shifts and weighs even ir­reg­u­larly shaped struc­tures, which must be pre­cisely han­dled for safety, on­go­ing re­li­a­bil­ity and in­tegrity of struc­tures in in­dus­tries such as build­ing and con­struc­tion, en­gi­neer­ing, min­ing, en­ergy, oil and gas, man­u­fac­tur­ing and ma­te­ri­als han­dling, ship build­ing and ma­te­ri­als test­ing.

For com­plex lift­ing jobs, the EVO Se­ries Syn­chro­nous Lift­ing Sys­tem re­places the need to man­u­ally co­or­di­nate mul­ti­ple lift­ing points dis­persed around a job by in­te­grat­ing the high­pres­sure hy­draulic cylin­ders in­volved with a PLC sys­tem to mon­i­tor and con­trol pre­cise move­ment and po­si­tion­ing of heavy loads. Through an in­te­grated HMI (Hu­man Ma­chine In­ter­face), all move­ments are man­aged from a cen­tral con­trol po­si­tion that dis­plays live op­er­a­tion with real-time sta­tus up­dates for each lift­ing po­si­tion.

“The EVO sys­tem has been one of the most suc­cess­ful prod­ucts we’ve stocked,” says Tri­dent Aus­tralia Gen­eral Man­ager, Jono Hansen. “It’s been a great in­vest­ment for us, be­cause com­pa­nies of­ten want to use it for a sin­gle pro­ject and can’t jus­tify buy­ing it out­right, so rent­ing it from us is a much bet­ter op­tion,” he said.

“As an au­tho­rised En­er­pac dis­trib­u­tor, stock­ing the EVO was a log­i­cal choice for us,” says Hansen. “A lot of our cus­tomers need to lift large struc­tures or heavy ma­chin­ery, and the safety, pre­ci­sion and ease-of-use of the EVO sys­tem makes it a pop­u­lar choice,” he said.

Tri­dent spe­cialise in pro­vid­ing com­plete so­lu­tions for high pres­sure and spec­i­fi­ca­tion f luid sys­tems and com­po­nents. They of­fer man­u­fac­tur­ing and de­sign of unique equip­ment as well as rentals, train­ing, ser­vic­ing and on­go­ing sup­port to cus­tomers in the oil and gas, min­ing, build­ing and con­struc­tion and other in­dus­tries that utilise hy­draulic equip­ment.

The new EVO syn­chro­nous sys­tem of­fers eight stan­dard hy­draulic con­trol modes and can con­trol four, eight or 12 points with one hy­draulic power unit (HPU). A mas­ter con­trol unit is also avail­able that of­fers daisy chain con­trol of up to 4 EVO sys­tems, giv­ing a max­i­mum of 48 lift­ing points.

En­er­pac’s WA Ter­ri­tory Man­ager, Josh Allen, re­cently com­pleted EVO sys­tem train­ing with the Tri­dent Aus­tralia team and Can­ning Vale. “The guys loved it,” said Allen. “Time sav­ing is a big ad­van­tage of syn­chro­nous lift­ing. The process does not have to be stopped af­ter any in­cre­men­tal value, checked, man­u­ally re­mea­sured and cor­rected. The EVO-Sys­tem car­ries out th­ese ac­tions dur­ing the en­tire lift­ing process, even with low lift­ing or low­er­ing speeds. De­pend­ing on the ap­pli­ca­tion, time sav­ings up to 60 per­cent can be achieved. This keeps Tri­dent’s cus­tomers very happy,” he said.


Safety ben­e­fits of the PLC-con­trolled sys­tem in­clude elim­i­na­tion of the po­ten­tial for er­ror with the multi-op­er­a­tor man­ual con­trol ap­proach. The dig­i­tally pre­cise EVO-sys­tem in­cor­po­rates warn­ings and stop func­tions. It of­fers full mon­i­tor­ing and con­trol, with pro­gram­mable fail­safe mon­i­tor­ing and safety alarms.

“The pre­ci­sion con­trol of­fered by the EVO sys­tem re­duces the risk of struc­tural dam­age by bend­ing, twist­ing or tilt­ing due to un­even weight dis­tri­bu­tion or load-shifts be­tween lift­ing points,” says Allen.

The easy-to-use and very user-friendly touch screen in­ter­face dis­plays the move­ment process, cylin­der po­si­tions and load read-outs by lift­ing points and to­tal load.

En­er­pac’s syn­chro­nous lift­ing tech­nol­ogy mon­i­tors and man­ages lift­ing, low­er­ing, weigh­ing, cen­tre of grav­ity, align­ment and load trans­fer pro­ce­dures of non-uni­formly dis­trib­uted heavy loads. The sys­tem in­cor­po­rates a vari­able fre­quency drive ( VDF) mo­tor, which fa­cil­i­tates low­er­ing of en­gine speeds and oil f lows as re­quired to op­ti­mise con­trol of the speed of lift­ing. This fea­ture also makes it pos­si­ble to use the sys­tem with var­i­ous ca­pac­i­ties of cylin­ders.

Us­ing this abil­ity to safely and pre­cisely con­trol lift­ing op­er­a­tions, as well as in­put pa­ram­e­ters for load and stroke tol­er­ance, users can safely and ef­fi­ciently per­form chal­leng­ing lift­ing ap­pli­ca­tions.

“The EVO-Se­ries Sys­tem al­lows one de­vice to con­trol the en­tire lift­ing op­er­a­tion while pro­vid­ing sta­tus up­dates at ev­ery point of the process, with­out the need for man­ual mon­i­tor­ing. By dig­i­tally mon­i­tor­ing and con­trol­ling lift­ing op­er­a­tions, users en­hance safety and elim­i­nate costly down­time vs. man­ual op­er­a­tions.”
