Longwall Bootend

Longwall Bootend

NEPEAN Longwall has been designing and building longwall Bootend’s for twenty years and we carry these proven principles into each design we adopt for our customers. A key feature of the NEPEAN Longwall design is the tail roller mounted on the moving carriage which ensures that the belt profile and pigs-trough are always placed in the optimum position to receive the coal discharge from the BSL. The NEPEAN Longwall skid bootend includes full side-shift and levelling functionality while the configuration is suitable for belt widths of up to 1,600mm (Other configurations available).

Standard Features:

  • Movable and steerable bedframe which carries the carriage on which the stage loader driveframe is mounted.
  • Side-slew frames at each end (300 mm of lateral movement)
  • Levelling jacks (4) at each corner
  • Large articulated skid shoe plates for low ground pressure
  • Length of frame suitable to allow 2 pushovers before advancing frame (options available)
  • Tiefenbach Control valves sharing core components with a shield control system (option for remote control)
  • Open frame design, eliminating the problem of fines accumulation in the Bootend structure
  • Low height inbye levelling mechanism to improve articulation of the Bootend under the BSL (e.g. when crossing ‘swillies’)
  • Single piece bedframe design or can be split for underground transport
  • Belt lift station to assist with belt structure removal

The Bootend has been designed specifically for the loading of coal at high production rates onto fast-moving longwall belts while incorporating features to prevent damage to the belting itself. Often included is an outbye belt lifting station and scraper system which simplifies belt structure handling and maintenance.

The bootend is the subject of particularly close scrutiny during the Design Risk Assessment (DRA) phase of the project given the critical interface between operators, outbye conveyor belt and longwall face equipment. Included in standard offers is a remote-control system for the Bootend to suit the remote operating requirement of the project. This enables operators to operate the Bootend from a safe distance local to the Bootend, or a Remote Operation Center, rather than standing adjacent to a Bootend that is moving.

Many different options have been accommodated into the Bootend including;

  • Operator access barriers
  • Cross over bridges
  • Operator protection enclosures
