(b) the buffer requirements (Clause 12) have been expanded and now cover oil buffers in more detail;
(c) top car clearances (Clause 13.4) have been more closely related to the amount of counterweighting;
(d) the requirements for terminal stopping devices (Clause 18) have been rewritten mainly for puposes of clarification;
(e) requirements have been added for hydraulic drive machines (Clause 20.9);
(f) the sections dealing with erection, operation, and maintenance of hoists have been relocated to an appendix, where they are now recommendations instead of mandatory requirements.

It has been approved as a National Standard of Canada by the Standards Council of Canada.
