Active anti-crush for Nifty HR12

Niftylift has developed a simple cut out and warning anti-entrapment device for its popular 33ft platform height HR12 self-propelled boom lift.
The new system can be specified for new or retrofitted to any older machines. It has been designed for rapid removal and re-fitting, taking just 60 seconds or so to either remove or replace for those rental companies that plan to offer the system as an option.

The first installation on an Elavation machine


The HR12 - along with most other full hydraulic control machines - has proved to be a challenge for most of the other systems on the market, such as Lavendon’s SkySiren. The fact that the ultra-low weight HR12 is a machine that has virtually no alternative in some applications was causing a problem for those contractors insisting on such devices being fitted to all boom lifts on their sites.

The first units have now been retrofitted to a number of machines owned by Milton Keynes-based rental company Elavation, which worked with Niftylift to specify the device.

To re-install the switch bar it is simply placed over the guardrails ....


The installation includes a small electrical box, a blue warning light, the longtitudinal pressure switch with its brackets and a connection to the control box. Once installed the removal of two security bolts and the unplugging of the power connection is all that is required to take off the main switch bar. A blanking plug then reactivates the system without the switch.

When the switch bar is not fitted a blanking plug is used to allow the machine to work


Barry Brady of Elavation said: “We believe that there is no substitute for well trained operators, but whilst there is this ground swell of panic around this issue we will continue to meet our client’s demands as they arise. Niftylift’s attitude has been first class and we believe that the solution they have provided has shown how seriously they take our concerns.”

“Retro-fitting this equipment will allow our older units to still comply with on-site demands, and meet our lightweight unit commitments to our customers.”
