Read and abide by this WARNING placard posted on the crane.
Crane operation is extremely dangerous when close to an electrical power
source. A mobile hydraulic crane is more vulnerable due to the natural
maneuverability and versatility of the crane.
Extreme caution must be exercised by all personnel working with and around
your crane when in the proximity of an energized power source or power lines.
All personnel must be adequately warned of safety procedures.
