1. Scope 1.1
This Standard describes the design, construction, load rating, installation,
erection, inspection, maintenance, repair, modification, test, and operation of
lattice and telescopic boom mobile cranes. 1.2
This Standard applies only to machines that have all of the following
fundamental characteristics:
(a) the crane comprises, or is mounted on, a non- or self-propelled, crawler-
or wheel-mounted, mobile base;
(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 is attached. 1.3
This Standard applies to crawler-mounted cranes, commercial truck-mounted
cranes, and boom trucks and wheel-carrier-mounted cranes, as well as any
variations thereof that retain the fundamental characteristics of these cranes.
(See Appendix J for illustrations of mobile cranes.) 1.4
This Standard is applicable only to machines when they are used for hoisting
(lifting). 1.5
Machines within the scope of Clause 1.3, and equipped with hooks, magnets,
grapples, clamshell 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
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,
conveyors, augers, drills, and amusement rides (eg, bungee jumping);
(b) articulating boom (knuckle boom) cranes;
(c) hydraulic and cable-operated excavating equipment, such as power shovels
and backhoes;
(d) automotive wreckers and tow trucks designed to clear wrecks and haul
vehicles;
(e) railway cranes, locomotive-mounted cranes, and rail-mounted cranes;
(f) side boom tractors, as used in pipeline work, to which ASME Standard B30.14
applies;
(g) mobile lifting devices designed specifically for use in powerline and
electric utility service, such as digger derricks (radial boom derricks)
intended to auger holes for and to set power and telephone poles;
(h) vehicle-mounted aerial devices, which include ladder (sign erection)
trucks, to which CSA Standard CAN/CSA-C225 applies;
(i) trolley boom cranes (underrunning trolley hoist);
(j) truck-mounted overhead, gantry, and bridge cranes;
(k) stacker cranes;
(l) self-propelled elevating work platforms, to which CSA Standards
CAN3-B354.1, CAN3-B354.2, CAN3-B354.3, and CAN3-B354.4 apply;
(m) lift (forklift) trucks equipped with booms; and
(n) tower cranes (fixed, climbing, and travelling), to which CSA Standard Z248
applies. 1.7
Where "shall" is used in this Standard, it indicates a mandatory requirement.
Where "should" is used, it indicates a recommendation, the advisability of
which depends on the situation.
