CSCS Slinger/Signaller case studies
CSCS Slinger/Signaller · Put your knowledge to work in context.
The CSCS Slinger/Signaller card is a construction-industry competence credential for workers who attach, balance and guide loads moved by cranes and other lifting equipment, and who relay signals between the lifting team and the plant operator. It is aimed at people already working, or preparing to work, in a lifting team under a appointed person's lift plan, and it is typically obtained alongside a relevant vocational qualification or industry training scheme. Assessment combines a health, safety and environment test with a specialist multiple-choice paper covering legal duties and responsibilities, lifting accessories and their inspection, slinging techniques and load control, signalling and communication, and the planning and coordination of lifting operations. Preparation works best in layers: learn the legal framework and the responsibilities of each member of the lifting team first, then move to accessory identification, safe working load and rating concepts, then to practical slinging geometry and signal conventions. The CSCS Slinger/Signaller case studies are 5 cases and about 2,518 words.

You are asked to lift a 3.2 t machined steel fabrication using a two-leg chain sling in a basket hitch around the load. The legs are unequal: one leg is 2.0 m and the other is 3.0 m, both rated 3.15 t in a single-leg vertical hitch.
