CSA Group CSA Z150:26 National Standard of Canada Safety code on mobile cranes

Preface

This is the sixth edition of CSA Z150, Safety code on mobile cranes. It supersedes the previous editions published in 2020, 2016, 2011, 1998, and 1974.

This Standard is designed 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 mobile cranes;

• provide direction and guidance to manufacturers and buyers of mobile cranes regarding the minimum standards expected of such machines in Canada;

• provide direction and guidance to owners, employers, supervisors, workers, users, and others concerned with, responsible for, or involved in the application and use of mobile cranes; and

• guide Canadian federal, provincial/territorial, and other regulatory bodies in the development and promulgation of appropriate health and safety legislation and directives concerning mobile cranes.

This edition includes the following changes:

• revised requirements on

– ropes;

– rope replacement criteria;

– daily and annual inspection;

– severe weather conditions;

– cranes not in regular use;

– boom disassembly;

– ring cranes;

– personnel lifting platforms; and

• changes for clarity.

This Standard was developed by CSA Group with funding support provided by the Canadian Association of Administrators of Labour Law — Occupational Safety and Health (CAALL-OSH), including provincial and territorial governments, as well as the Government of Canada. CSA Group is solely responsible for the content of this Standard, and CSA Group and the funding bodies disclaim any liability in connection with the use of the information contained herein.

This Standard was prepared by the Technical Committee on Mobile Cranes, under the jurisdiction of the Strategic Steering Committee on Occupational Health and Safety, and has been formally approved by the Technical Committee.

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 Overview

This Standard describes the design, construction, load rating, installation, erection, inspection, maintenance, repair, modification, test, and operation of lattice and telescopic boom mobile, and ring-mounted cranes.

Note: See Annex A for illustrations of mobile cranes and Annex B for illustrations of parts of a mobile crane.

1.2 Inclusions

This Standard applies only to machines that have all of the following fundamental characteristics:

a) the crane comprises of, or is mounted on,

i) a non- or self-propelled, crawler- or wheel-mounted mobile base; or

ii) a temporary ring support frame or rail structure;

b) the crane is designed and manufactured for the primary purpose of hoisting and lowering loads by means of tackle suspended from a boom;

c) the boom is lattice or telescopic and capable of being elevated and lowered in the vertical plane and of being rotated (swung) from side to side in the horizontal plane;

d) the tackle is suspended from the boom and is capable of being increased and diminished in length; and

e) the crane utilizes an engine(s) or motor(s) of sufficient power to

i) elevate and lower the boom in the vertical plane with the load suspended from the tackle;

ii) rotate (swing) the boom in the horizontal plane with the load suspended from the tackle;

iii) increase and diminish the length of the tackle with the load suspended from the tackle; and

iv) in the case of a self-propelled crane, propel the vehicle, carrier, or base on which or to which the boom and hoist mechanism are attached.

1.3 Application

This Standard applies to crawler-mounted cranes, commercial truck-mounted cranes, boom trucks, wheel-carrier-mounted cranes, railway cranes, locomotive-mounted cranes, rail-mounted cranes, and ring-mounted cranes, as well as any variations thereof that retain the fundamental characteristics of these cranes.

1.4 Applicability to hoisting machines

This Standard is applicable only to machines when they are used for lifting (hoisting).

Note: Some basic machine types within this scope are used alternatively for hoisting service and for applications not considered to be hoisting service. All of the requirements of this Standard are applicable to such machines when used for hoisting service. Clause 4.14 contains requirements for machines when used for other than hoisting service.

1.5 Lifting service requirements

Machines within the scope of Clause 1.3, and equipped with hooks, magnets, grapples, clam shell buckets, orange peel buckets, and other devices intended to connect or attach the tackle to the load for the purpose of hoisting or lowering a freely suspended load, are considered to be in lifting (hoisting) service.

1.6 Exclusions

This Standard does not apply to

a) machines within the scope that have been converted or adapted for uses not considered to be lifting (hoisting) services. These conversions and applications include power shovels, excavators, draglines, concrete pumps (see CSA Z151), conveyors, augers, drills, and amusement rides (e.g., bungee jumping);

b) articulating boom (knuckle boom) cranes (see CSA Z150.3);

c) hydraulic and cable-operated excavating equipment (e.g., power shovels and backhoes);

d) automotive wreckers and tow trucks designed to clear wrecks and haul vehicles;

e) side boom tractors, as used in pipeline work (see ASME B30.14);

f) mobile lifting devices designed specifically for use in power line and electric utility service, such as digger derricks (radial boom derricks) intended to auger holes for and to set power and telephone poles (see ANSI/ASSP A10.31);

g) vehicle-mounted aerial devices (see CSA C225);

h) trolley boom cranes (under-running trolley hoist);

i) truck-mounted overhead, gantry, and bridge cranes;

j) stacker cranes;

k) self-propelled elevating work platforms (see CSA B354.6, CSA B354.7, and CSA B354.8);

l) lift trucks (forklifts) equipped with booms; and

m) tower cranes (i.e., fixed, climbing, mobile, travelling, and self-erecting) (see CSA Z248).

1.7 Terminology

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.

1.8 Units of measurement

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.
