This is the second edition of CSA Standard CAN/CSA-Z256, Safety Code for Material Hoists. It supersedes the first edition, published in 1972 as CSA Standard 2256.
The following are the major changes that have been made in this new edition:
(a) the hoistway enclosure requirements (Clause 6) have been clarified and are now more comprehensive;
(b) the terminal stopping devices requirements (Clause 19) have been rewritten mainly for purposes of clarification;
(c) requirements have been added for hydraulic drive machines (Clause 21.9);
(d) the sections dealing with erection, operation, and maintenance of the hoist have been relocated to an appendix where they are now recommendations instead of mandatory requirernents.
This Standard applies to structures and hoists that are not a permanent part of buildings, structures, or other works and that are used during construction, alteration, or demolition to raise and lower materials connected with or related to a building project.
This Standard covers the design, construction, installation, operation, and acceptance inspection and testing of material hoists.
This Standard does not apply to
(a) hoists for transporting personnel;
(b) temporary elevators installed in their 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;
