Crane Terminology

Cranes are a widely used piece of equipment worldwide in many different capacities. Types of cranes vary depending on types of work in different situations. Crawler cranes, overhead cranes, hydraulic cranes and gantry cranes can be utilized to complete a variety of projects.

Let’s discuss the components of a mobile hydraulic crane as it is the most recognizable crane used in a variety of industries.

Crane Definitions

• Operators Cab – A housing that covers the operator’s station.
• Outrigger – An extendable supporting device used to level the crane and increase stability.
• Outrigger Float or Outrigger Jack – The hydraulic cylinder on the outrigger beam which extends vertically to raise and lower the crane for leveling.
