Device for advancing the conveyor in working operations

摘要

To win minerals in working operations in underground mining, the conveyor must be advanced to the working face during every winning action. An accurate degree of advance is important in order to avoid conveyor losses, breakdowns and difficulties in operation. To force a defined advance distance, control cylinders are allocated to the advancing cylinders. The control cylinders can alternatively be integrated in the advancing cylinders or can be arranged outside them. <IMAGE>
