BlokAlert is a wireless, audio-visual warning system attached to the crane's hook block that alerts nearby personnel with recognisable sounds and visible beacons to increase awareness and reduce the risk of accidents.
BlokAlert is a wireless, audio-visual warning system that can be quickly and easily deployed to the hook block of the crane. When activated by the lifting crew, the BlokAlert unit produces a
recognisable audible alert and visible beacon that can be seen and heard by site personnel in proximity to the hook block or load. This forewarns the workforce to the position and movements of the hook block, increases awareness, and reduces the risk of being struck by the crane’s hook block, lifting accessories or load.
Design Overview:
1a) The lifting crew/rigger: The hand-held fob is activated by the riggers or lifting crew. When operated, the signal is transmitted to the receiver on the hook block of the crane
and/or:
1b) In the operator’s cab: The transmitter is activated by the footswitch in the crane cab. When operated the signal is transmitted to the receiver on the hook block of the crane.
2) On the hook block: On the receipt of a signal from the transmitter, the receiver is activated, alerting the workforce to the proximity of the hook block.
