Tractel Spring Recoil & Wire Line Load Arrestors

The "OVERSPEED" BLOCSTOP, type BSO is a safety device, used as fall arrest device for man-riding operations.

When man-riding is concerned, no safety measure can be considered excessive; that is why the usage of the BLOCSTOP is required with the GRIPHOIST/TIRFOR. 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 strictest 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 BLOCSTOP is a fall-arrest secondary safety device which, when fitted to an appropriate TIRFOR / TIRAK wire rope, can be used in conjunction with almost any lifting equipment. Available with different capacities: 800kg, 1000kg, 1600kg, and 3200kg. While lifting a load or tensioning a wire rope the rope passes through the BLOCSTOP. There is no need to operate the BLOCSTOP. For lowering the load or releasing the wire rope the BLOCSTOP is opened by lifting the operating lever upwards.
