Preface This is the second edition of CSA Z150.3, Safety code on articulating boom cranes. It supersedes the previous edition published in 2011. This Standard is designed to a) provide requirements to guard against and minimize injury to workers, and otherwise provide for the protection of life, limb, health, and property, by specifying minimum safety requirements for articulating boom cranes; b) provide direction and guidance to manufacturers and buyers of articulating boom cranes regarding the minimum standards expected of such machines in Canada; c) provide direction and guidance to owners, employers, supervisors, workers, users, and others concerned with, responsible for, or involved in the application and use of articulating boom cranes; and d) guide Canadian federal, provincial/territorial, and other regulatory bodies in the development and promulgation of appropriate health and safety legislation and directives concerning articulating boom cranes. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 This Standard specifies requirements for the design, construction, installation, inspection, testing, maintenance, and operation of articulating boom cranes. Note: In this Standard, the terms \"articulating boom crane\" and \"crane\" have the same meaning. 1.2 This Standard applies to the following types of cranes: a) commercial truck or trailer mounted cranes (see Figures A.1 to A.4); b) stationary cranes; and c) mobile cranes. 1.3 This Standard applies to cranes that a) are mounted on a fixed or mobile base; b) lift, swing, and lower loads at various radii by means of an articulating boom (that can also telescope), and which can be equipped with a load hoist mechanism; c) use an engine(s) or motor(s) of sufficient power to i) perform the load handling functions described in Item b); and ii) where applicable, propel a rolling base on a trailer; and d) use hooks or load handling devices for hoisting or lifting. 1.4 This Standard does not apply to a) mobile cranes covered by CSA Z150; b) cranes with booms that do not articulate; c) hydraulic and cable-operated excavating equipment such as power shovels and backhoes; d) cranes with booms constructed of non-conductive materials and vehicle-mounted aerial devices (see CAN/CSA-C225); e) cranes designed primarily for personnel baskets, platforms, ladders, etc., as opposed to material handling; f) cranes used in forestry and logging applications; g) scrap handlers; h) cranes mounted on a ship or boat; i) concrete pumper trucks (see CAN/CSA-Z151); j) self-propelled elevating work platforms (see CAN/CSA-B354.1, CAN/CSA-B354.2, and CAN/CSA-B354.4); and k) lift (forklift) trucks equipped with booms (CSA B335). 1.5 In this Standard, \"shall\" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; \"should\" is used to express a recommendation or that which is advised but not required; and \"may\" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.6 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
