Operating Principle

The OVERSPEED BLOCSTOP operates automatically. It consists essentially of a clamping jaw mechanism of the TIRFOR-type and a centrifugal governor, which permanently checks the speed of the wire rope passing through the BLOCSTOP. The jaw  mechanism automatically clamps onto the wire rope when there is a sudden increase in speed.

The OVERSPEED BLOCKSTOP can be manually operated by pressing the EMERGENCY-STOP-button (38). The jaws should close automatically and the control lever (04) should return to its CLOSED position. To guarantee the correct operation we recommend that the EMERGENCY STOP (38) be carried out manually at least once a day.

The BSO is reset by means of the control lever (04). The wire rope must always be introduced through the upper wire rope entry (12) = control lever side.

During the operation the centrifugal weights must rotate, which should be regularly checked through the window (51).

Operating Instructions

To feed in the wire rope:

  • Ensure that the lever (04) is in the "OPEN" position.
  • Feed in the wire rope from the top, into the rope guide (12) and pass it through the machine.

To remove the wire rope:

  • Maintain the lever (04) in the "OPEN" position.
  • Push in the EMERGENCY STOP button (38) and maintain completely depressed.
  • Remove the wire rope.
