Terex brand Genie will release the new Lift Guard Contact Alarm, a secondary guarding system designed to provide operators additional protection.

The system is designed to immediately activate and alert others that the operator may need help and is configured as a standard on most new Genie Z (articulated) and S (telescopic) boom lifts.

It is active whenever the footswitch on the boom is enabled.

The system features an activation cable fitted above the boom lift’s platform control panel. When pressure is applied to the cable, it disconnects and activates the system.

When the system is activated, all machine lift 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 lift 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 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 also be operated from the ground if necessary.

The alarm is visible from the ground due to its bright yellow colour. Its design provides visibility of the control panel and aerial job site for the operator, without interfering with machine operation.

The 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.

The Genie Lift Guard Contact Alarm system is available pre-installed from the factory or as an aftermarket kit, which can 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.

However, the accessory is not yet available on Genie Z-33/18 articulated boom lifts or Genie TZ-34 and TZ-50 trailer-mounted booms.

Genie also offers its Operator Protective Structure (OPS) which may be attached to boom lifts with 1.8 m (6 ft) to 2.4 m (8 ft) platforms. The tubular steel structure is designed to transfer the kinetic energy into surrounding structures while maintaining a protected area for the operator in some circumstances. It weighs 16kg and is bolted directly on the boom lift’s platform, meaning no modifications are needed. The Genie Lift Guard Contact Alarm and OPS systems can be used together.

The Genie Lift Guard Contact Alarm system will be available from June 2017.
