THE DALE WALKING RETURN CONVEYOR

INTRO. . .

The Dale Walking Conveyor has been developed to provide a mechanised means of self advancing the development conveyor tail end complete with all necessary ancillary equipment required in the heading. By no longer relying on the heading machine to pull in the tail end the twin benefits of less disruption to the machine cutting cycle and a more powerful advance force is realised. The design is such that the tail end can be advanced effortlessly against the pull of the loop take up on both gradient and dip where conventional methods would struggle.

The system has been successfully applied in many U.K. AND European mines and has proved to be a cost effective method of improving productivity and safety.

COST EFFECTIVE. . .
 

Less manpower required in heading.

Low capital cost of equipment as compared to a shuttle car heading.

Low maintenance - the equipment can be used for several drivages before requiring major overhaul.

SAFETY. . .

Eliminates safety problems associated with shuttle car movement.

Reduces the risk of injury during the moving up of equipment.

Eliminates the use of chains to pull the conveyor tail end.

PRODUCTIVITY. . .

When used in conjunction with a bridge conveyor the cutting and loading material become a continuous process.

All electrical and ventilation equipment such as panels, transformers, fans and ducting are advanced with the walking conveyor reducing the time required for move ups.

Simple design is high on reliability, low on maintenance.

Dale Mansfield have recently won contracts for three Russian and Italian mines totalling 7 units.
