Specifications | PDF
 OSHA Regulations for maritime construction and general industry require each rail mounted bridge and portal crane located
outside an enclosed structure to be fitted with an operable wind indicating device. The Belfort Model 6115 crane wind alarm
system meets these requirements.
Wind speed is detected by the latest technology ultrasonic sensor Belfort Model 6115 mounted on the crane or nearby
structure. The sensor provides an output voltage proportional to the wind speed to a cab mounted alarm console. The wind
alarm console provides:
- Digital Wind Speed Indicator
- Low Limit Warning Light
- High Limit Warning Light
- Red Caution Light
- Stop Operation Horn
- High and Low Limit Test Switch
A built-in time delay, variable from 00-40 seconds
can be set to prevent very short duration gusts from
causing false alarms.
In the event an alarm occurs, the operate-with-
Caution red light begins to flash. Then, if the preset
Danger level is reached, the stop-operation horn will
blow, telling the crane operator to secure the crane,
stop operation and seek shelter. If additional
connections are made, the alarm can cause a remote
warning light to flash, sound a remote horn or siren, and automatically actuate the crane brakes to prevent the crane from rolling.
