CSA Z150.3-17:2018 pdf download.Safety code on articulating boom cranes
4.1.1 Design requirements
Cranes shall, as a minimum, meet the applicable requirements of EN 13001. Design requirements for special design booms (non-production models) or special hoist conditions may be further determined by either the crane manufacturer or an engineer.
4.1.2 Engine exhaust gases
Engine exhaust shall be piped and discharged to protect the operator from noxious and temperature effects. Exhaust pipes shall be guarded or insulated to prevent contact by and injury to the operator when performing normal duties.
4.1.3 Hydraulic systems
Hydraulic systems shall meet the following requirements:
a) Exposed lines subject to damage shall be protected, where practical.
b) Means shall be provided for checking the manufacturer's specified pressure settings in each hydraulic circuit.
c) All hydraulic components normally rated according to bursting strength, such as hose, tubing, and fittings, shall have a minimum bursting strength of at least three times the operating pressure for which the system is designed.
4.2.3.1 In some areas of the operating range, the load ratings may be governed by structural and hydraulic competence rather than crane stability. The following conditions describe operating ranges where the rating may be limited by factors other than stability:
a) Loads that produce a condition of tipping increase rapidly and reach extreme values as the minimum operating radius and tipping fulcrum of the crane/vehicle are approached. At some radii, these loads are of such magnitude that they cannot be used as rated capacity limitations without resulting in excessive weight that would severely limit performance and ratings at the longer radii where most work is done. Hence, load ratings at some radii may be based on the structural competence of the crane/vehicle rather than stability.
b) A non-symmetrical mounting requires a higher loading to produce a condition of tipping in a direction other than that of least stability, on which the load ratings are established. Therefore, if the crane/vehicle specification includes additional ratings for directions other than the least stable,such ratings may also be governed by structural competence rather than stability. For such specified additional ratings, the work area shall be indicated and, for those ratings that might be governed by tipping loads, the applicable percentage factors in Clause 4.2.2.1 shall not be exceeded.
4.2.1 General
The ability to lift a load may be governed by crane stability or structural competence.
Note: The actual load that can be safely raised or lowered is influenced by such additional factors as freely suspended loads, wind or ground conditions, condition of rail track, rubber tires condition and inflation, and tread width, boom lengths, proper operating speeds for existing conditions, and, in general, competent operation.CSA Z150.3-17 pdf download.
