and a deduction shall be made from load ratings in accordance with the manufacturer’s instructions, unless the manufacturer offers separate capacity charts for operations with attachments. The effect of light fixtures, pile lead adaptors, and other nonstandard attachments shall be deducted from the load ratings. No load shall be lifted aver the front area of a truck-mounted crane, except as approved by the crane manufacturers and noted on the load chart.
When cranes included in the scope of this CSA Standard are mounted on barges and pontoons, factors in addition to those stipulated In Clauses 3.1.1.2 and 3.1.1.3 will influence the stability and structural competence. The load ratings for a crane on a barge or pontoon shall be modified as recommended by the manufacturer or a professional engineer.
3.1.2 Ratings Governed by Structural Competence
3.1.2.1
In some areas of the operating range, the load ratings may be governed by structural and hydraulic competence rather than crane stability. Conditions below describe operating ranges where the rating may be limited by factors other than stability:
(a) The loads that will produce a condition of tipping increase rapidly and reach extreme values as the minimum operating radius and Upping fulcrum of the machine 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, which 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 machine rather than stability.
(b) A nonsymmetrical mounting requires a higher loading to produce a condition of tipping in a direction other than that of least stability, on whkh the load ratings are established. Therefore, if the crane 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 3.1.1.2 shall not be exceeded.
3.1.2.2
For a lattice boom crane, the manufacturer shall design the crane to meet the performance requirements of SAE Recommended Practice J987. Crane design Standards produced by AFNOR, BSl, CEN, DIN, ISO, and JISC are acceptable providing the load ratings determined for the crane by the respective Standard do not exceed those which would be determined if the crane were load rated under SAE Recommended Practice 1987 requirements. Where testing and strain gauging are part of the Standard, they shall be carried out.
3.1.2.3
For a t&escopic boom crane, the manufacturer shall design the crane to meet the performance requirements of SAE Recommended Practice Ji 063. Crane design Standards produced by AFNOR, 851, CEN, DIN, ISO, and JISC are acceptable providing the load ratings determined for the crane by the respective Standard do not exceed those which would be determined if the crane were load rated under SAE Recommended Practice J1063 requirements. Where testing and strain gauging are part of the Standard, they shall be carried out.CSA Z150-98 pdf free download.
