Overview of Alberta's New Maintenance Requirements For Elevators, Dumbwaiters, and Freight Platform Lifts under Alberta Regulation 216/97
GENERAL
An Alberta certified journeyman elevator constructor must perform maintenance, repairs, and replacements or directly supervise a registered apprentice doing the work. Under the new Alberta law, minimum required maintenance include:
| • |
|
Inspect, examine, and test all parts and functions at required or scheduled intervals to ensure safe operating condition; |
| • |
|
Clean, lubricate, and adjust applicable components at regular intervals - repair or replace defective, worn, damaged or broken components as necessary to prevent the device from becoming unsafe for operation; |
| • |
|
Immediately adjust, repair, or replace defective parts directly affecting safe operation. |
A logbook for each device must be kept on site or available at all time (record of all activities referred to this regulation and trouble calls for the last 5 years).
Up-to-date wiring diagrams are required in machine rooms (electrical protective devices and primary directional circuits).
A professional engineer (copy of certification recorded in logbooks) must certify changes in design of any components that might affect safe operation.
3 MONTH PROCEDURES
Examinations required for aforementioned criteria for functional compliance with applicable standards
| NOTE: |
|
A variance issued by Alberta Labour (Standata ED-99-001) provides for extensions to 12 months maximum by the original manufacturer, a professional engineer, or an elevator maintenance contractor provided the owner is notified and a written copy regarding details of variances are placed in the log book. |
Examine and hand test overspeed safeties. If hand testing indicated potential malfunction, test safeties. Include governor pull through force test if excessive pull through or damage to governor rope.
Examine gland packing of valves and cylinders of hydraulic drive machines for excessive leaks and hydraulic fluid level in drive machine. Record amounts added and date in logbook.
Examine hydraulic fluid level in hydraulic buffers.
Examine suspension and overspeed governor wire ropes for excessive wear and broken wires (must meet elevator code criteria for replacement).
Examine all landing and car door mechanical and electrical components including:
| • |
|
interlocks, locks, contacts |

Dismantle and clean driving machine brakes, examine all components and test to ensure car will decelerate from rated speed when power removed from driving machine. Examine brake linings or any other component or any change affecting the operation or adjustment of the brake.
Test hydraulic driving machine relief valve setting and reseal if the control valve mechanism is altered or the seal is broken.
Examine exposed hydraulic cylinders visually and for cylinders that are not exposed, test for leaks.
Examine all parts relating to free-fall, overspeed, and uncontrolled low speed protection devices as per manufacturer's recommendation and test for functioning (full-load tests not required).
PROCEDURE REQUIRED AT INTERVALS OTHER THAN EVERY THREE MONTHS
Perform plunger return test on oil buffers every 5 years.
Re-socket, replace or move hoist rope sockets of elevators and dumbwaiters with winding drum drives every 12 months for overhead machines and 2 years for machines below or at the side of the hoistway.
