(b) shall meet the requirements in the document, Electrical ESA SPEC-00X-13, published Specification for Tower Cranes, by the Electrical Safety Authority; and, (c) shall have control equipment incorporating solid state devices, a programmable logic controller and/or software systems in operating and control circuit, designed and installed to meet circuit performance classification that is control reliable meeting category 3 or better in accordance with, (i) ISO 13489-1, Safety of Machinery safety related parts for – control systems, or (ii) EN 954-1:1996, Safety of machinery Safety-related part of – control systems Part 1: General principles for design. ss.(2) - There would be an implementation period for owners of – cranes already in Ontario when the new proposed requirements After a SPECIFIED DATE, a tower crane, other than one come into effect, to give owners time to make necessary described in ss.(1), that is erected on a project, modifications to their cranes so they can comply with the design requirements of CSA Z248-04, Code for Tower Cranes, as well as (a) shall be designed and manufactured in accordance with the ESA’s Electrical Specification for Tower Cranes and the control and, equipment requirements in ss.156.(1)(b) and (c). (b) shall comply with the requirements in ss.(1)(b) and (c). QUESTION TO INDUSTRY: How long should this implementation period be e.g. 2 years? Industry is being asked to provide feedback to the Provincial Health and Safety Committee on how much time would be reasonable to give to crane owners to enable them to bring their existing cranes into compliance with the new design requirements. cranes in service on a project when the new proposed requirements come into effect, would be allowed to continue to operate. However, once their work is completed and they are dismantled and removed from a project, they would also have to be reviewed and brought into compliance with the new design requirements. QUESTION TO INDUSTRY: The regulation of tower cranes in Europe has historically required more rigorous inspections of older cranes. Anecdotal evidence indicates that crane owners,
