GIGASENSE – Crane Safety Monitor

The Gigasense Crane Safety Monitor is an electronic control unit to be used in overload protection systems. The Crane Safety Monitor evaluates and computes signals from force transducers and can be set for alarm at preset alarm limits. By installing the Crane Safety Monitor, hazards for personnel and material are avoided. The Crane Safety Monitor will also record the operation of the hoist. The Crane Safety Monitor is designed both for indoor and outdoor operation in aggressive and demanding industrial environments.

Crane Safety Monitor Safety and Economy

  • Protects personnel and property against hazards due to overload
  • Enhances safety for personnel in crane operations
  • Monitors the operational conditions of the crane as well as the recommended service intervals. Through this monitoring the crane can be fully utilized during its entire life period (Safe Working Period)
  • Crane Safety Monitor is self-checking. All faults result in overload indication.

The Crane Safety Monitor 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).
