Part 6 Cranes, Hoists and Lifting Devices

Section 81 Safety code for material hoists

CSA Standard CAN/CSA-Z256-M87 (R2006), Safety Code for Material Hoists, applies to hoists that are not a permanent part of structures and that are used to raise and lower material connected with or related to a building project. See Figure 6.19.

Figure 6.19 Example of a material hoist

The standard does not apply to

(a) hoists for moving people,
(b) temporary elevators installed in hoistways during the construction of buildings and incorporating a part of the permanent elevator to be installed later,
(c) manlifts, counterbalanced or endless-belt type,
(d) mine elevators,
(e) cranes and derricks,
(f) window cleaners and swingstages,
(g) mobile forklift trucks and similar equipment, and
(h) rope-guided and non-guided construction hoists for moving people.

The standard covers the design, construction, installation, operation, inspection and testing of material hoists. The following is a list of some of the standard’s more critical requirements:

  • Part 6 Hoistway Enclosure – this describes spacing and material requirements for a structure that isolates the hoistway, i.e. the space travelled by the car or counterweight, from all other parts of the building.
  • Part 7 Hoistway Landings and Doors – this describes requirements for that portion of a floor, balcony, or platform used to receive the hoisted materials.
  • Part 8 Cars – this describes requirements for the load-carrying units.
  • Part 15 Operation and Operating Devices – this describes requirements for the hoist’s actuating controls.
  • Part 20 Safeties and Governors – this describes requirements for devices to stop and hold the car or counterweight in case of overspeed or free fall or if the hoisting ropes slacken.
  • Part 25 Communication – this describes the requirements for communication and signal systems.
  • Part 26 Inspections and Tests – this describes the requirements for when inspections should take place, what should be included in the inspection and the tests to be carried out.
