Here are the theory test questions for A60 Mobile Crane.
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 A60 paper

Name THREE ways in which wind speed can affect the lifting operation. (3 marks)
When must a banksman or signaller be used before moving a crane? (2 marks)
If the words STOP NOW are given to the crane operator by radio during the lift, what action must the operator take? (2 marks)
When working in a confined area or space:
a) what danger can be present with regards to the counterweight of the machine,
