Abstract:In view of the imperfection of the existing protection system of the endless rope winch,the lack of offside,overspeed,tension drop and other protection,once the above-mentioned failures can not stop in time,and it will bring great security problems.Based on PLC control technology and existing materials and accessories,a new protection and control system of the endless rope winch was designed,which made the operation of the endless rope winch meet the requirements of "Coal Mine Safety Regulations".It has been well applied in the field,to save the investment cost and to be worth popularizing.
Keywords:,endless rope winch, protection system, PLC, tension reduction protection device, overspeed protection
