Question

1

Who determines the lifting/object handling capacity of the machine?

2

Accessories must only be attached to manufacturers' approved lifting points. Explain THREE possible consequences if the recommendations are not followed.

3

According to legislation, when are check valves and a rated capacity or load moment indicator required?

4

Before lowering into or moving a drag box into a trench, what trench-related checks must be made?

5

Explain the purpose of a lift plan.

6

If a hook is fitted to the machine for lifting purposes, what must be checked before use?

7

If attaching accessories to a quick-hitch coupler, give TWO reasons why should the coupler be tilted in the downwards position (ram extended)?

8

If the accessory attachment point is not part of the bucket, give TWO reasons why it should be removed.

9

If the load inadvertently or accidentally lands, what course of action should be taken?

10

If the machine's rated capacity/object handling capacity chart is not available for reference, what other methods can be used to determine the machine's lifting capacity?

11

If travelling with a load, name FIVE factors that must be taken into account by the operator before moving.

12

Manufacturers' lifting or object handling capacity charts apply (in all known cases) when the machine is level. What is the effect if a load is lifted or travelled facing downhill on a downhill slope?

13

On both tracked and wheeled types:

a) what differs between lifting over the side compared to over the front or the rear of the machine?

b) Explain why.

14

The safe working load (SWL) or working load limit (WLL) of a multi-leg chain sling only applies in what TWO conditions or configuration?

15

Using the lifting capacity diagram for A59:

a) if the machine is equipped with a 2.5 m long dipper, what is the maximum lifting capacity in tonnes at a 6 m radius/reach over the sides of the track with the load at 3 m height

b) in principle, if a longer dipper is fitted, what effect does that have on the lifting capacity (assuming same size bucket and machine configuration)?

16

What effect can a swinging load have on an excavator?

17

What is regarded as the danger or hazard zone during a lifting operation?

18

What is the main purpose of a rated capacity indicator (RCI) or load moment indicator (LMI)?

19

What makes up the total (or gross) weight of a load that is to be lifted?

20

What needs to be inspected on a quick-hitch coupler if attaching lifting accessories for the lifting of slung loads?

21

When an object is needed to be lifted on a site, what should be the first consideration?

22

When slewing with a load, where should the operator be looking?

23

Which parts of the machine is the radius (for lifting) measured from?

24

Why must the controls be isolated before each load can be attached or disconnected by the slinger?

25

Why should long loads be lifted using a swivelling type lifting accessory?

26

With regards to lifting accessories, irrespective of who supplied the accessories, what THREE factors should be ensured before the accessories are used?
