Automatic Overload Protection System - AOPS

Our AOPS system solution is built to comply with the EN 13852-1. Any AOPS has to be designed in close cooperation with the Crane OEM or other person with similar knowledge to make sure that the combined solution meet the requirement.

Mipeg X is utilise inputs from several sensors and input signals from the crane control logic to combined comply with the following key points:

  • AOPS to be installed for boat lift/off-board lifts only (disarmed over platform).
  • AOPS operates on all reeving configurations.
  • Activation of AOPS shall disengage the hoist and slew brakes.
  • Triggering value shall not be less than that of an on-board lift.
  • Have a response time to prevent structural damage to the crane.
  • Shall have a retaining force sufficient to suspend a load corresponding to the on-board lift capacity.
  • When overload situation no longer exists, the system shall automatically reset but be available to activate again.
  • Procedure and frequency of periodic testing of system to be included in crane information for use.
  • Hoist lowering limit to be overridden.
  • Manual overriding of AOPS not permitted except for man riding.
  • The system shall not allow uncontrolled lowering of the load.
  • Continuous visual signal to state if the AOPS is available or not.
  • Distinguishable visual and audible alarms of activation.

The Mipeg X display will keep the operator informed about the AOPS status at all time.

The AOPS may be tested easily, activating a special test logic in the system.

The Manual Overload Protection System – MOPS, will be available at a lower threshold and adding the operators input.
