The radial deviation of the rotor and the wind mechanism driving wheel connected with the rotor is about 1 ~ 1.5mm, (BZDY11-BZD41 type backward, BZD51-BZD62 type forward, attention should be paid when adjusting) so that the brake ring on the brake wheel and the end cover of the rear bearing are loose, and the rotor runs, so as to achieve the running state. When the power fails, the magnetic tension dissipates, and the screw jack supplier, under the effect of the compression spring, clamps the brake wheel and the rear bearing end cover, with the help of the friction torque caused by the brake ring, completes the braking in an instant.

Explosion-proof electrical control box, control buttons and electrical equipment basic principle: explosion-proof electrical control box is installed on the left side of the reducer or the relative side of the operation equipment and the motor, the switching power supply according to the soft cable type switching power supply into the box, the control box according to the cable and control button, limit switch and motor connected.

Explosion-proof type overload limiter: according to the customer must, can add the explosion-proof type overload limiter, vendor manual jacks is avoid overweight when lifting operation safety protection devices, automatic alarm when hoisting do 95% rating load, achieve 105%, the fully automatic truncation switching power supply, overweight protection purpose.
