Technical improvement on winding drive of movable beam of portal-type bucket wheel stacker-reclaimer

Dou Xukui  
The insufficiency in the winding drive of movable beam of MDQ3000 /3000.650 portal-type bucket wheel stacker-reclaimer may cause winding mechanism failure,hence to seriously threaten the whole equipment safety.To solve this problem,the original designed double-gear coupling is replaced with drum-type gear coupling with brake wheel,with improvement on the original reducer.Throughout the operation observation for nearly one year,it shows that the improved winding drive is provided with reliable and stable operation,and a zero failure rate.
