Here are the theory test questions for A02 Crawler Crane above 10 tonnes.
During the theory test you'll be asked a maximum of 40 questions.
Please note that your paper will include all the questions we have marked here with an asterisk *. In addition you will have a random selection of the other questions that are not marked here with an asterisk.
These questions will appear on every A02 paper

Give FOUR reasons that may cause the crane to overturn. (4 marks)
Name THREE ways in which wind speed can affect the lifting operation. (3 marks)
What is the purpose of a roll or ROPS frame? (2 marks)
When working in a confined area or space: a) what danger can be present with regards to the counterweight of the machine, b) when should measures be taken and c) what measures should be implemented? (3 marks)
Only two legs of an 8 tonne four-legged chain sling are being used. What is the maximum load that can be lifted? (1 marks)
Before leaving the cab for a rest break, after parking and switching off the machine, what final action must be carried out? (2 marks)
If the hook block inadvertently (accidentally) lands, what course of action should be taken? (2 marks)
How does the deflection of the boom or jib affect the lift? (2 marks)
What effect can a swinging load have on a crane? (1 marks)
If assisting in fitting a fly jib to the crane, why is it important that the manufacturers' procedures are followed precisely? (2 marks)
Wind speeds can be variable throughout the working day. What action must be taken to ensure safe working conditions are maintained? (1 marks)
During work, the engine starts to overheat. Explain the danger if someone tries to remove the radiator or expansion tank cap. (2 marks)
a) What determines the minimum distances that any part of plant and machinery has to be kept from over head electricity lines and
b) explain why a distance should be kept. (4 marks)
When MUST a banksman or signaller be used before moving a crane? (2 marks)

Two cranes are working in the same vicinity that encroach the operating radius of each. What actions would the lift plan or method statement normally specify? (3 marks)
If checking the oil level using a dipstick, why must gloves be worn? (1 marks)
State the functions or job role of the following personnel: a) Appointed Person, b) Crane Supervisor, c) Slinger, d) Signaller. (4 marks)
