Features
The TDWK Disc Brake compliments the wide range of Witton Kramer drum brakes, and is suitable for all drives – particularly where high stopping energy is required.
TDWK brakes are suitable for a wide range of disc diameters, and can be mounted on one or both sides of a disc. The thrustor is symetrically positioned so the brake is not ‘handed’ as is usually the case with brakes of this type.
They are operated by the Witton Kramer HD thrustor which can be interchangeable with other European thrustors if required – these can be fitted without modifying the brake.
The brakes are A.C. operated from supplies up to 660 Volts, 50/60 Hz and are designed for demanding applications such as on heavy duty cranes, conveyors and process lines.
