Tower crane operator rescue system

Swedish articulated tower crane manufacturer Artic Crane and UK crane rental company City Lifting have developed and launched a new rescue system for tower crane operators, dubbed the iRaptor DRS (Driver Rescue System).

The new Davit arm-type system solves the problem of getting the crane operator down to the ground in the case of a heart problem or any other debilitating illness when in the cab. It is said to be easily fitted to most crane platforms and has an overall height of 3.1 metres and working radius of one metre. Maximum load capacity is 250kg with 125kg person lift.

The system uses a 1.1kW motor with the hook controlled by a frequency invertor which gives a smooth, controlled ride for the patient. Rope length is 70 metres and hoist speed 25 metres a minute. Should the power fail during a rescue situation, a battery back-up system, allows the descent to continue. The iRaptor is also fitted with a top-run over switch and overload system.
