MHWK Brakes

Electro-hydraulic Thrustor Operated Drum Brakes

Sizes

160mm - 500mm

Torques

190 Nm - 5150 Nm

Features

Witton Kramer MHWK Brakes have a fixed torque, and no external springs. This means the torque cannot be changed inadvertently, the torque springs are protected from the environment inside the thrustor and thus makes the brake very competitive.

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.

The MEWK Brakes can also be fitted with Witton Kramer KT Industrial thrustors and TKF Flameproof thrustors.

The brakes comply with the British standard, BS 466 and with the requirements of the German standard DIN 15435 in respect of drum diameter,shoe width, shoe clearance, fixing centres and centre height, and fixing bolt holes.
