• (2) At least one man car that is part of a trip of man cars shall be designed to transport an injured person on a stretcher.

• (3) The first man car of a trip shall be secured by a primary fastening arrangement that is

  • (a) in the case of a direct hoist rope system, a rope socket;

  • (b) in the case of an endless hoist rope system, a rope clamp; and

  • (c) in the case of a locomotive system, a coupling.

• 84. (1) Where a man car is used on a gradient exceeding 4 per cent, it shall, for the purpose of coupling it with other mine cars, be equipped with

  • (a) three continuous draw-bars made of steel; or

  • (b) a single draw-bar composite of rolled steel sections and rolled steel plate.

• (2) The continuous draw-bars referred to in paragraph (1)(a) shall be

  • (a) extended the full length of the man car;

  • (b) securely bolted to the floor and base sills of the man car; and

  • (c) visible for inspection.

• (3) Where man cars of a trip are used on a gradient exceeding 4 per cent, the man cars shall be equipped with safety brakes that are

  • (a) interconnected and operated simultaneously with the safety brakes of the other man cars of the trip;

  • (b) manually operable from at least one man car of the trip;

  • (c) automatically operable by an overspeed governor on one of the man cars of the trip in the event of a 20 per cent overspeed;

  • (d) capable of stopping the maximum load of the man car at the maximum gradient of the roadway at the maximum overspeed governor setting; and

  • (e) of a fail-safe design.

• 85. (1) Where man cars that are equipped with three continuous draw-bars are adjacent in a trip, they shall be connected to each other by

  • (a) couplings at the centre draw-bar; and

  • (b) safety chains at the two side draw-bars.

• (2) Where man cars that are equipped with a single draw-bar are adjacent in a trip, they shall be connected to each other by

  • (a) couplings at each end of the draw-bars; and

  • (b) safety chains at two attachments on the chassis of each adjacent man car.

• (b) the first man car of a trip on a direct hoist rope system shall be secured, in addition to the primary fastening arrangement referred to in paragraph 83(3)(a), by a secondary fastening arrangement that is capable of holding at least 200 per cent of the maximum tensile load of the trip in the event of a failure of the primary fastening arrangement.
