Lift guard con­tact alarm sys­tem

DEMM Engineering & Manufacturing - - PRODUCT WATCH - en­quiry #170406

The first in the next gen­er­a­tion of in­no­va­tive ac­ces­sories, the new Ge­nie Lift Guard Con­tact Alarm sys­tem can, in some cir­cum­stances, pro­vide ad­di­tional op­er­a­tor pro­tec­tion, says the man­u­fac­turer. The Ge­nie Lift Guard Con­tact Alarm sys­tem is en­gi­neered as an elec­tronic sec­ondary guard­ing sys­tem de­signed to im­me­di­ately ac­ti­vate and alert oth­ers that the op­er­a­tor may need help. This new ac­ces­sory is con­fig­ured as a stan­dard ac­ces­sory on most new Ge­nie Z (ar­tic­u­lated) and S (tele­scopic) boom lif ts. It is ac­tive when­ever the footswitch on the boom is en­abled.

“Ge­nie pro­tec­tive so­lu­tions con­tinue to evolve,” says Mitch Ely, Ge­nie Na­tional Oper­a­tions Man­ager Aus­tralia, “[and] this new con­fig­u­ra­tion is a sig­nif­i­cantly dif­fer­ent de­sign from its pre­de­ces­sor, the Ge­nie Op­er­a­tor Pro­tec­tive Alarm (OPA).”

How does it work? The new Ge­nie Lift Guard Con­tact Alarm sys­tem fea­tures an ac­ti­va­tion cable fit­ted above the boom lif t’s plat­form con­trol panel. When pres­sure is ap­plied to the cable, it dis­con­nects and ac­ti­vates the sys­tem. When the sys­tem is ac­ti­vated, all ma­chine lif t and drive func­tions are stopped to pre­vent ad­di­tional move­ment in the plat­form, and an alarm sounds and bea­cons flash, no­ti­fy­ing ev­ery­one near the Ge­nie boom lif t that the op­er­a­tor may re­quire as­sis­tance.

The sys­tem is only func­tional when the footswitch is de­pressed, and mo­tion does not re­sume with­out hu­man in­ter­ven­tion. All no­ti­fi­ca­tions and func­tion re­stric­tions con­tinue un­til the sys­tem is re­set by sim­ply click­ing the ac­ti­va­tion cable back into place; there is no need to restart the en­gine or cy­cle e-stop power to re­sume ma­chine func­tion­al­ity. The ma­chine can be op­er­ated from the ground, if nec­es­sary.


“We en­gi­neered the new Ge­nie Lift Guard Con­tact Alarm sys­tem to be vis­i­ble from the ground with its bright yel­low colour. In the plat­form, it is as un­ob­tru­sive for the op­er­a­tor as pos­si­ble,” says Ely. “It is sim­ple to use, and it is used in con­junc­tion with op­er­a­tor train­ing re­quired by in­dus­try stan­dards world­wide that could en­hance safe work prac­tices on aerial job sites.” Boast­ing a ro­bust con­fig­u­ra­tion with sim­ple parts, the Ge­nie Lift Guard Con­tact Alarm de­sign pro­vides ex­cel­lent vis­i­bil­ity of the con­trol panel and aerial job site for the op­er­a­tor, not in­ter­fer­ing with ma­chine op­er­a­tion.

This new de­sign in­cludes an ad­di­tional freemove­ment zone be­tween the cable and the con­trol panel that may al­low for op­er­a­tor mo­bil­ity once the sys­tem is ac­ti­vated. “Un­like other de­vices on the mar­ket, the Ge­nie Lift Guard Con­tact Alarm sys­tem could re­duce the risk of op­er­a­tors ap­ply­ing un­in­ten­tional con­tact pres­sure on the boom’s con­trol panel,” adds Ely.

The Ge­nie Lift Guard Con­tact Alarm sys­tem is avail­able in­stalled stan­dard from the fac­tory or as an af­ter­mar­ket kit, which can eas­ily be in­stalled in less than 30 min­utes with only a few fas­ten­ers and elec­tri­cal har­ness con­nec­tors. It fits on plat­forms in the Ge­nie Z- and S-boom fam­i­lies and can be retro­fit­ted on units dat­ing back to 2003. This ac­ces­sory is not yet avail­able on Ge­nie Z-33/18 ar­tic­u­lated boom lif ts or Ge­nie TZ-34 and TZ-50 trailer-mounted booms. The Ge­nie Lift Guard Con­tact Alarm sys­tem will be avail­able in June 2017 and will be on dis­play at HIRE17 Con­fer­ence (10-11 May) in Sydney.
