Regulations are current to 2014-04-02 and last amended on 2006-06-15. Previous Versions

Surface Hoist Tests and Inspections

  •  (1) During each shift, a hoist operator shall test the surface hoist, including the safety devices connected to it.

  • (2) Where tests are performed in accordance with subsection (1), the hoist operator shall test

    • (a) the overwind preventor to verify that the cage or trip does not travel more than 0.6 m past the top or the bottom of the run; and

    • (b) the speed controller with the cage midway in the shaft or with the trip part of the way along the run.

  • (3) Subject to subsection (4), where a surface hoist has not been operated for more than four hours, before persons are transported on that hoist, a trial wind shall be carried out over the lesser of

    • (a) the complete run of the cage or trip, or

    • (b) 400 m.

  • (4) Except in the case of an emergency, where a surface hoist has not been operated for any period because of an accident or defect, a full trial wind shall be carried out before lowering or hoisting is resumed.

  • (5) A qualified person shall test

    • (a) at least once every 24 hours, the overwind preventor, speed controller and other safety devices of a surface hoist that is used only for transporting persons;

    • (b) at least once every week, the overwind preventor, speed controller and other safety devices of a surface hoist that is used for hoisting materials; and

    • (c) at least once every month, the braking system of every surface hoist, including the emergency brake, overwind preventor, speed controller, other safety devices and the devices referred to in paragraph 65(1)(c) and subparagraph 65(1)(f)(ii).

  • (6) The hoist operator or qualified person who carries out the tests referred to in subsections (1) to (5) shall make a record of those tests in a book kept for that purpose.

 At least once every 24 hours, a mine mechanic shall

  • (a) inspect the external parts of all surface hoists, including cages, mine cars, tackling equipment, head gear, ropes, sockets, rope paths and couplings, that are in use in the coal mine; and

  • (b) make a record of the inspection referred to in paragraph (a) in a book kept for that purpose.

Hoist Rope Standards and Tests

 Every hoist rope shall be made of steel and have a factor of safety of not less than six.

  •  (1) No hoist rope shall be placed in service unless it has been tested for breaking strength by a rope-testing laboratory.

  • (2) The employer shall keep, for every hoist rope, every test certificate issued in respect of the rope by a rope-testing laboratory and a certificate from the manufacturer of the rope.

  • (3) The certificates referred to in subsection (2) shall contain the following information in respect of the hoist rope:

    • (a) the name and address of the manufacturer;

    • (b) the manufacturer’s rope number;

    • (c) the date of manufacture;

    • (d) the diameter, expressed in millimetres;

    • (e) the mass per unit length, expressed in kilograms per metre;

    • (f) the number of strands;

    • (g) the class of core;

    • (h) the percentage by mass of lubricant in the core;

    • (i) the trade name of the interior rope lubricant;

    • (j) the number of wires in a strand;

    • (k) the diameter of the wires, expressed in millimetres;

    • (l) the breaking strength of steel from which the wire is made, expressed in kilopascals;

    • (m) the results of the standard torsion test of the wires;

    • (n) the actual breaking strength; and

    • (o) the extension of a test piece when tested to destruction.

  • (4) For every hoist rope, the following information shall be recorded in a record book:

    • (a) the name of the company from which the rope was purchased;

    • (b) the date of purchase;

    • (c) the manufacturer’s rope number;

    • (d) the date on which the rope is installed in or removed from a particular location;

    • (e) the location referred to in paragraph (d);

    • (f) the mass of the cage or mine car in respect of which the rope is installed;

    • (g) the maximum load for which the rope is designed;

    • (h) the maximum length of rope in service below the sheave;

    • (i) the maximum mass of rope in service below the sheave;

    • (j) the factor of safety of the rope in each location where it is installed;

    • (k) the dates on which rope samples are taken;

    • (l) the dates and results of tests for breaking strength; and

    • (m) where applicable, the date of permanent removal from service and the reasons therefor.

  • (5) The employer shall keep the record book referred to in subsection (4) at the coal mine in which the rope is in service

    • (a) during the period in which the rope is in service; and

    • (b) during the five-year period immediately following the day on which the rope is permanently removed from service.
