How BlokAlert Works

The Lifting Crew/Rigger
The handheld system is activated by the riggers or lifting crew. When operated,
the signal is transmitted to the receiver on the hook block of the crane.

In the Operator’s Cab
The transmitter is activated by a foot-switch in the crane cab. When operated,
the signal is transmitted to the receiver on the hook block of the crane.

On the Hook Block
On receipt of a signal from a transmitter, the Receiver is activated, alerting
the workforce to the proximity of the hook block.
