A Coupler tilted downwards
B Coupler tilted upwards
C Ram contracted
D Ram extended
Correct Answer: A Coupler tilted downwards, D Ram extended
Explanation: Tilting the coupler downwards, with the ram extended, will make re-attachment easier and reduce the chance of unintended pivots.
7. You are carrying out a lifting operation over the excavator's side, rather than its front. How will this affect the vehicle's centre of gravity?Give ONE answer
A It will shift closer to the centre of the machine's footprint
B It will shift to the front edge of the machine's footprint
C It will shift to the outer edge of the machine's footprint
D It will shift to the rear of the machine's footprint
Correct Answer: C It will shift to the outer edge of the machine's footprint
Explanation: Lifting over the side will shift the vehicle's centre of gravity in that direction. This will affect the vehicle's centre of gravity.
8. What is the principal role of an RCI or an LMI?Give ONE answer
A To warn nearby pedestrians
B To warn when the rated capacity has been exceeded
C To warn when the vehicle is becoming unstable
D To warn when underground cables are nearby
Correct Answer: B To warn when the rated capacity has been exceeded
Explanation: A rated capacity indicator (RCI) or a load moment indicator (LMI) serve mainly to warn the operator when the rated capacity has been exceeded.
9. Which TWO of the following together describe the danger zone created during a lifting operation?Give TWO answers
A The area 3m around the vehicle
B The area above or below the load
C The area within the machine's radius
D The operator's cab
Correct Answer: B The area above or below the load, C The area within the machine's radius
Explanation: The danger zone during lifting operations is the area within the vehicle's radius that falls both above and below the load.
10. What is a risk assessment for?Give ONE answer
A Establishing what kind of medical support is required on site
B Identifying and eliminating all hazards
C Identifying hazards and introducing suitable control measures
D Identifying hazards to be entered into insurance documentation
Correct Answer: C Identifying hazards and introducing suitable control measures
Explanation: Risk assessments are used to identify hazards and decide how to control them.
11. What is a lift plan for?Give ONE answer
A To ensure that all hazards have been identified and mitigating measures are put in place
B To ensure that all relevant parties understand how to safely move the load
C To ensure that the operation will be carried out as quickly as possible
D To ensure that the project management team can defend itself if prosecuted
Correct Answer: B To ensure that all relevant parties understand how to safely move the load
Explanation: A lift plan is put in place to ensure all relevant parties know how to safely carry out a lifting operation.
12. You have just finished loading the excavator onto a trailer so a driver can transport it to a different site. Which of the following must you ensure?Give THREE answers
A That hydraulic components are grounded with the pressure removed
B That the engine is off
C That the parking brake is off
D That the windows are shut
Correct Answer: A That hydraulic components are grounded with the pressure removed, B That the engine is off, D That the windows are shut
Explanation: These are all checks that must be carried out - but the parking brake must be on.
13. You will be carrying out excavation in a confined space. Which TWO of the following are important to consider before you begin?Give TWO answers
A Are you in close proximity to hazards?
B Do you have the correct medical insurance?
C Have you received the correct vaccinations?
D Where will you put the spoil?
Correct Answer: A Are you in close proximity to hazards?, D Where will you put the spoil?
Explanation: Confined spaces present various obstacles that you must consider - among them are that you may be in close proximity to hazards, and will need to determine in advance where to place spoil.
14. Which of the following is NOT something that may cause an excavator to tip?Give ONE answer
A The ground is soft
B The load is unevenly distributed
C The machine is low on fuel
D The tyres (if the excavator has wheels) are soft
