You can report crane or derrick operation that is unsafe or without a permit, license, or certificate. Violations are issued when appropriate.
A crane is a large machine used to lift and lower heavy materials and transport them to other places.
It may have:
- A hoist
- Wire rope
A derrick is a type of crane with a movable, pivoted arm and one tower as a pole hinged freely at the bottom. A basic derrick is controlled by lines, usually four of them, connected to the top of the mast and powered manually or with motors.
Most derricks are stationary while cranes can move from place to place.
In your report include:
- What is being hoisted
- If items are being hoisted over pedestrians
- How the crane or derrick is unsafe
- If a permit is posted
