9.5.1 SWL

The SWL of the clamp selected should allow for the weight of the lifting appliance and any other tackle which will be suspended from it. Under normal conditions of use, i.e. where there are no hazardous conditions the SWL will be the same as the working load limit. When used in conjunction with sheave blocks, due allowance should be made for the downward pull on the effort rope in establishing the SWL. (See 1.A4 APPENDIX 4 - STRUCTURES)
