Motorized and Manually Operated Crab Winches from 1000kg to 15000kg safe working loads.
Our Crab Winches are designed to be robust and to facilitate Large rope capacities with safe working loads ranging from 1000kg to 15000kg. Failsafe electromagnetic brakes are fitted on motorized units and are fully reversible. Our Crab Winches can be supplied with electric, air or hydraulic motors. All electric motors conform to NEMA, EEMAC or IEC specifications. Ball bearings are installed on all shafts to minimize friction loss and to minimise maintenance. No mounting pedestal is required due to its rirect floor mounting design.
Motorized Crab Winches
All motorized units are supplied with standard TEFC flange mount electric motors. Fitted with electromagnetic brakes at the rear, coupled to a simple direct drive primary reduction gearbox and with optional failsafe braking done via spring applied brake callipers, fixed to the side of the rope drum. These units are ideally suited for stage sinking and high lift applications.
Standard input voltages of 220V Single phase or 380V 3 Phase 50 Hz or 60 Hz apply. All our motorized crab winches are fully reversible, giving the operator complete control of the winch load in both directions.
Manually Operated Crab Winches
Manually operated crab winches are controlled via two large ring handles mounted on each side of the winch. Braking is done via a heavy duty pawl and ratchet system assisted by a positive locking drum brake.
