Terex Utilities introduces levelling turret

Terex Utilities has launched its Tru-Level ‘tilting pedestal system’ for the Terex SC and HRM series of aerial devices, allowing them to operate safely on slopes of up to 20 degrees.

The new levelling system copes with the real life conditions without the resulting increases in stress on the slewing gearbox when rotating ‘up (or down) the hill,’ it can also reduce set-up time because it eliminates the need to crib up the outriggers on slopes that are too great for the outrigger levelling ability, and does not limit boom operation or load charts.

Other benefits of the Tru-Level system is that it keeps the work platform level longitudinally, and therefore makes it a more comfortable working environment for the operator.

Jon Promersberger, Terex project engineer said: “This Terex system will save both service time and costs thanks to easier access to the collector block and rotation bearing bolts, as well as decreased stress on the rotation gearbox during uphill work.”

“The Tru-Level pedestal system allows operators to save time during the set-up process by being able to situate the truck on terrain that is outside of the recommended degree of slope without having to either ‘dig out’ or ‘build up’ for proper levelling. And it’s easy to use - operators simply need to park, set the truck and activate.”

To use the system operators position the front of the truck pointing directly downhill, and then set the parking brake and place wheel chocks under all four wheels. The parking brake is then released to allow the chassis to roll into the wheel chocks and then reset before engaging the PTO. Operators must also verify that they are operating on a side slope of five degrees or less. The lower controls are used to raise the upper boom about 600mm, allowing Tru-Level pedestal to be levelled fore and aft using the indicator mounted on the turret. Finally, operators will lower the upper boom to the platform rest or set platform for ground access, select the upper controls and then enter the basket and secure their safety harness.
