Guide to safe operation of tower cranes

Tower cranes are essential tools in the construction industry, but they can be dangerous if not operated safely. The following guide provides key safety considerations to follow when operating a tower crane.

  1. Pre-Operation Safety Checks

Before operating a tower crane, it is essential to perform pre-operation safety checks. The checks should include the following:

  • Ensure that the crane is on a stable and level surface.
  • Check the condition of the crane, including the cables, pulleys, and other components.
  • Verify that the crane is properly lubricated.
  • Confirm that all safety devices, such as limit switches and overload protection, are functioning correctly.
  • Inspect the crane’s electrical system, including wiring and switches.
  • Verify that the crane’s load chart is on display and readable.
  1. Operator Safety

The tower crane operator is responsible for ensuring the safety of the crane and those working around it. The following guidelines should be followed by the operator:

  • Only qualified and trained personnel should operate the crane.
  • The operator should not leave the crane unattended while it is in operation.
  • The operator should not operate the crane if they are fatigued, under the influence of drugs or alcohol,tower crane hoist, or have any physical or medical condition that impairs their ability to operate the crane safely.
  • The operator should always wear personal protective equipment, including a hard hat, safety glasses, and gloves.
  • The operator should follow all manufacturer instructions for operating the crane.
  • The operator should always be aware of the crane’s surroundings and potential hazards, such as power lines or other structures.
  1. Load Safety

Load safety is a critical aspect of tower crane operation. The following guidelines should be followed to ensure load safety:

  • The operator should never exceed the crane’s rated capacity, as specified in the load chart.
  • The operator should always use proper rigging techniques to secure the load.
  • The operator should inspect the load and rigging before lifting it.
  • The operator should ensure that the load is balanced and stable before lifting it.
  • The operator should avoid sudden or jerky movements when lifting or lowering a load.
  • The operator should not lift or move loads in windy or other adverse weather conditions.
  • The operator should be aware of the crane’s boom length and radius to prevent hitting other structures or objects.
  1. Communication

Effective communication is essential when operating a tower crane. The following guidelines should be followed:

  • The operator should have a clear view of the load and the work area.
  • The operator should communicate with other personnel on the job site, including the signal person, using a two-way radio or other communication device.
  • The operator should follow hand signals from the signal person, who is responsible for directing the movement of the crane and load.
  • The signal person should be trained and qualified to give hand signals and direct crane operations safely.
  • The signal person and operator should always have visual contact with each other.
  • The operator should not move the crane or load until they receive a clear signal from the signal person.


Tower crane operation can be dangerous if proper safety measures are not followed. The guidelines outlined in this safety operating guide can help ensure that the crane is operated safely and effectively, reducing the risk of accidents and injuries. Remember, safety should always be the top priority when operating a tower crane.
