There are certain basic techniques that must be practiced to ensure the safest possible operation of a crane. These include:

  • The driver carrying out a brief check of the crane at the beginning of his shift
  • Loads should not be left hanging on the hook at the end of a shift
  • Those working above floor level who are likely to be struck by the crane or its load must be warned
  • The crane must not approach nearer than 20 feet to anyone working on the track
  • Loads should not be carried over people
  • Loads must be lifted vertically – the crane must not be used to drag a load
  • Power to the crane should be switched off when the crane is left unattended

Mobile cranes present extra hazards in use. The following point need to be adhered to in order to ensure safety:

  • The travelling height of the crane with the jib lowered and raised should be marked on the crane
  • Overhead obstructions or hazards should be clearly identified and marked with maximum clearance height
  • Care should be taken to ensure that no one is trapped to counterbalance weights as the crane slews
  • The condition of the ground should be checked before lifting with a mobile crane and it should not approach close to excavations
