Crane Operation Safety Measures
Issue
During jib crane operation, the operator on the ground must be alerted to any danger of falling luggage or colliding with cargo.
Proposal
The output from the control panel during crane operation is transmitted to the WIO transmitter, which wirelessly sends signals to the WIO receiver. While the crane is in operation, EHV with a maximum sound pressure of 110 dB connected to the WIO receiver, alerts ground operators to prevent accidents. Wiring for the transmitter/receiver is no longer necessary, even when the control panel is located at a high place and wiring to the ground is difficult or distant.
