Crosby BlokAlert is a wireless, audio-visual warning system that can be quickly and easily deployed to the hook block of a crane.

Once activated by the lifting crew, the BlokAlert receiver emits a recognisable audio-visual signal that can be seen and heard by site personnel in proximity to the hook block or load.

This alerts the workforce to the position and movements of the hook block, it increases awareness and reduces the risk of being struck by the crane’s hook block, lifting accessories or load.

In many work sites the distance between the horn, often located near the operator’s cab, and the load, is inconsistent and does not efficiently warn site personnel to the position of the hook block or load. The same can be said for airhorns or whistles when used by riggers. In both scenarios, the attention of the work force is diverted to where the sound is coming from, as opposed to the hazard.

System comprises:

• 1 x BlokAlert receiver
• 1 x Hard shell transport case
• 2 x Operator telemetry remotes
