Crane Safety Monitor
PIAB CSM Crane Safety Monitor is an electronic control unit to be used in overload protection systems. The PIAB CSM evaluates and computes signals from force transducers and can be set for alarm at preset alarm limits. By installing the PIAB CSM, hazards for personnel and material are avoided. The PIAB CSM will also record the operation of the hoist. The PIAB CSM is designed both for indoor and outdoor operation in aggressive and demanding industrial environments.
The CSM can monitor the following functions/operations
Slack Rope status
Load Indication (Load in Hook)
Load (Peak Value) * Set Switch Limits
Total Service Time * Overload Service Time
Number of Hoisting Cycles
Levels for Change of Hoisting Speed
Service Time converted into Full-Load Service Time (For computing of Safe Working Period as per ISO 12482-1, Cranes – Condition monitoring).
85-264 VAC, 47-440 Hz or 12-370 VDC.
Lacquered steel box, dimensions 380x300x155 mm.
IP65 Temperature Range: -20ºC to +70ºC.
