Wind Crane Alarm

Crane Alarm 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.
