Code for tower cranes
Preface

This is the fourth edition of CSA Z248, Code for tower cranes . It supersedes the previous editions published in 2017, 2004, and 1975. It applies to the design, construction, installation, inspection, testing, maintenance, and safe operation of tower cranes. This new edition of CSA Z248 includes updated requirements to the following

  • self-erecting cranes;
  • severe weather;
  • ropes;
  • jobsites with multiple cranes; and
  • crane inspections.

This Standard was prepared by the Technical Committee on Tower 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 General

This Standard applies to the design, construction, installation, dismantling, operation, inspection, testing, and maintenance of tower cranes. This Standard applies to tower cranes powered by electric motors or internal combustion engines and any variations thereof that retain the same fundamental characteristics. The scope includes cranes of these types that adjust operating radius by means of a

  1. boom-luffing mechanism
  2. trolley traversing a horizontal boom or incline boom
  3. or a combination of the two.

This Standard is also intended to cover self-erecting tower cranes. Tower cranes can be mounted on fixed or travelling bases. Additional mounting means can include arrangements that permit the crane to climb in the structure being built or that permit increasing the tower height as the structure rises

1.2 Purpose

This Standard is designed to

  1. guard against and minimize injury to workers, and otherwise provide for the protection of life, limb, and property by prescribing safety requirements and protective measures
  2. provide direction to owners, employers, supervisors, crane erectors, operators, and others concerned with, or responsible for, its application
  3. and guide governments and other regulatory bodies in the development, promulgation, and enforcement of appropriate safety directives.

It is also expected that this Standard will have a major application in industry, serving as a guide to the manufacturers, purchasers, and users of the equipment

1.3 Application

This Standard applies to new and existing tower cranes unless otherwise specified in this Standard.

1.4 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.

1.5 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.
