Tractel "Blocstop BSO" Overspeed "Fully Automatic" Wire Line Fall Arrest Block for Materials or Man-riding Applications. Range to 2300kg
The "OVERSPEED" BLOCSTOP, type BSO is a safety device, used as fall arrest device for man-riding operations.
Where manriding is concerned, no safety measure can be considered excessive; that is why the usage of the BLOCSTOP® is required with the man-riding Tirfor® (Griphoist® in America) or man-riding Tirak (not to be confused with the materials lifting Tirak). The safety device consists of a brake mechanism formed by a pair of self clamping jaws pressed against each other by a powerful spring and enclosed casing. BLOCSTOPS® are UL classified as independent secondary brakes. Responding to the most strict safety regulations, they can easily be attached to most fittings. The Tirfor jaw type unit feting the Blocstop closes on the suspension wire rope and as it grips over a large area causes no damage to the cable.
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 regularlychecked through the window (51).
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.
