1 Radius and/or Angle Indicators are only required if the SWL varies with jib radius or angle.

2 An anti-two block device may be removed during piling operations as it is possible it may be damaged or shaken loose and cause a further risk. Where an anti-two block warning or cut-out device is not
available, then two block damage protection if fitted is acceptable.

3 If fitted with hoist.

4 Recommended.

5 Pillar cranes feature a fixed or slewing jib mounted off a fixed, free-standing column, post or pillar. A jib crane is a fixed or slewing jib mounted off a fixed structure such as a building frame.

6 The rating chart for pillar and jib cranes may simply be appropriate SWL indications clearly marked on the jib.

7 Any item of plant configured to list suspended loads and used for purposes other than duties directly associated with the primary function of the machine.

8 Where it is impracticable to fit a radius indicator to a mobile plant (e.g. excavators) it will be acceptable for the controller to demonstrate that his operator(s) is or are fully trained and assessed in the use of
this plant as a crane.

1 Truck loader-type cranes in service in New Zealand as at 01/01/09 will not be required to be retrofitted with additional load safety devices. However, crane owners and operators may benefit from their fitment.

2 Radius and/or Angle indicators are only required if the SWL varies with the jib radius or angle.

3 "New or refitted cranes" means new cranes fitted to a vehicle or other mounting for the first time, and used cranes fitted to a different vehicle or other mounting after 01/01/09.

4 if fitted with hoist.

5 Design verification is not required for truck loader type cranes of SWL 0.9 - 15 t-m in New Zealand as at 01/01/09.
