Part 1. Details of regulated work or regulated product

This safety order is issued to all licensed elevating devices contractors and asset owners or their agent, and applies to all driving machine brakes of all makes and models maintained in conformance to section 8.6 of the ASME A17.1/CSA B44-2016 Safety Code for Elevators and Escalators.

Note: For elevating devices for which an installation permit is issued after April 30, 2020, this safety order supersedes safety order SO-L1 110225 4. For other elevating devices, safety order SO-L1 110225 4 continues to apply until the device has transitioned to the B44-2016 code, as per s.12.1 of the Elevating Devices Safety Regulation.

 

Part 2. Requirement(s) of this safety order

All licensed elevating devices contractors and asset owners or their agent are jointly responsible for meeting the requirements of this safety order. This safety order requires that all driving machine brake maintenance requirements conform to items 1 to 5 below.

  1. Examination and testing of brakes

All licensed elevating devices contractors that maintain elevators with driving machine brakes shall examine, maintain and inspect all driving machine brakes to meet the following requirements every 12 months:

  1. Ensure adjustment to the torque shown on the data plate, where provided.
     
  2. The driving-machine brakes shall be dismantled and cleaned annually to ensure safe and proper operation, including, but not limited to, the following components:
    1. residual pads (antimagnetic pads)

  1. Ensure full contact of the friction material on the braking surface. Means shall be provided to protect the braking surfaces from contamination caused by any driving machine fluid leak.
     
  2. The driving-machine brake shall be tested:
    1. to ensure that the car will decelerate from rated speed when power is removed from the driving machine and will brake while an empty car is travelling in the up direction at rated speed.
      Note: It is recommended that means other than the disconnect switch be used to remove the power.
    2. The device shall comply with section 8.6.4.6.2 of the ASME A17.1/CSA B44-2016 code if any part of the driving machine brake is changed or adjusted that can affect the holding capacity or decelerating capacity of the brake.
  1. Brake declarations

    1. The completed tests shall be documented utilizing the required form and shall be reported annually utilizing the excel spreadsheet included as part the requirements of the Annual Contractor Reporting Directive D-ED 2020-01.

  1. Maintenance records

    Maintenance records shall be updated accordingly and shall comply with the requirements of ASME A17.1/CSA B44-2016 section 8.6.1.4.1, except as modified in the Elevating Devices Safety Regulation and shall be viewable on site at all times as required by ASME A17.1/CSA B44-2016 section 8.6.1.2.
