The Genie Lift Guard contact alarm system is an optional accessory that can protect the operator in crushing scenarios, alerting others that the operator may need help.
Genie Lift Guard has an activation cable fitted over the control panel. The system is activated when pressure is applied to the cable – such as when the operator's torso is pressed down against the panel due to collision with an overhead obstacle. The machine's lift and drive functions shut off, an alarm sounds and beacons flash.
The system is only functional when the footswitch is depressed, and motion does not resume without human intervention. All notifications and function restrictions will 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.
Previously, Genie used a pressure-sensitive metal bar based on Lavendon’s SkySiren system, under licence.
“This new configuration is a significantly different design from its predecessor, the Genie Operator Protective Alarm,” said Genie product manager Marie Engstrom.
The new design includes an additional free-movement 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,” Marie Engstrom added.
The Genie Lift Guard Contact Alarm system is available installed from the factory or as an aftermarket kit, taking less than 30 minutes to install with only a few fasteners and electrical harness connectors, Terex says. It fits on platforms in the Genie Z- and S-boom families and can be retrofitted on units back to 2003. This accessory is not yet available on Genie Z-33/18 articulated boom lifts, GR-26J or Genie TZ-34 and TZ-50 trailer-mounted booms.
In addition to this new accessory, Genie continues to offer its operator protective mechanical solution (the former OPS), introduced in 2012, which is an overhead tubular steel structure to protect from crushing from above.The two systems can be used together if desired.
