A high risk work licence for dogging (class DG) is required by anyone who applies slinging techniques to a load, which includes:
- calculating safe angles for slings or chains
- selecting the type of sling or chain to be used
- selecting the correct method to secure the load
- selecting the safe method to lift or turn the load
- checking the conditions of lifting gear for wear and tear.
A DG licence is also required by anyone directing the operator of a crane or hoist in the movement of a load when the load is out of the view of the operator.
Dogging is the term given to a type of construction work performed by someone known as a “dogman”. They must be qualified in dogging (i.e., hold a valid Dogman ticket/licence).
Put simply: a dogger is responsible for anything below the crane hook. This entails safely slinging a load, which includes choosing and inspecting the lifting equipment, plus the method of slinging to move the load.
Dogging also consists of using training, knowledge and judgement to direct crane movement from outside of the machinist’s view, and of course, upholding and ensuring safety regulations and compliance.
Rigging (RB, RI, RA)
You can think of rigging as the next step up from dogging (in terms of the difficulty and risk in responsibilities on a site). In this way, all riggers are also dogmen (because they need to be qualified in dogging tasks too, as you will see below).
A rigger is responsible for anything below or above the crane hook.
Riggers use mechanical load-shifting equipment and gear to move, place and/or secure loads. They do this by using plant, equipment or members of a structure to ensure the stability, and to set-up and/or dismantle cranes or hoists.
