Virtual safety cage from Hiab
01 April 2008
Knuckle boom crane manufacturer Hiab has launched an operator protection system in Europe that creates a ‘virtual safety cage' around the control station.
The Hiab OPS (operator protection system) virtually eliminates the risk of a user being crushed by a vehicle-mounted crane, the company claimed.
The system was tested in Australia following a series of accidents there, in which operators were crushed by crane booms in situations rarely seen in Europe, said Hiab. OPS has boom- and slew-mounted sensors to prevent crane booms moving into a no-go zone. The size and position of the virtual safety cage can be adjusted to fit any crane vehicle and crane combination by making simple adjustments to the mechanics and the company's Space control system.
“Building upon our existing proven technology, the major benefits of the Hiab virtual cage system are that it does not reduce the productivity of the loader crane or create operator frustration,” added Lars Anderson, research and development manager at Hiab.
For cross-controlled cranes the system is active at all times and can only be disabled by pressing and holding down a release button positioned close to the control levers on the valve side.
