Code for tower cranes
Scope:
This Standard applies to the design, characteristics, 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:
a) boom-luffing mechanism;
b) trolley traversing a horizontal boom; or
c) 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.
Project need:
The new edition of Z248 is intended to be updated to reflect current industry terminology and technology advancements. Further, this new edition would aim to ensure clarity of the requirements of the Standard. Updates would also include specific considerations for self-erecting cranes, sites with multiple cranes and anticollision devices. Moreover, concerns regarding extreme weather events and inspection checklists will be addressed. The anticipated impact of this Standard is to provide guard against and minimize injury to workers, and otherwise provide for the protection of life, limb, and property by prescribing safety requirements; provide direction to owners, employers, supervisors, crane erectors, operators, and others concerned with, or responsible for, its application; 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 manufacturers, purchasers, and users of the equipment.
