Crawler cranes, also known as mobile cranes, are all-terrain cranes equipped with a set of tracks or legs rather than wheels. They are self-propelled and can traverse all terrains, even soft grounds, making them highly maneuverable at construction sites. Mobile cranes have excellent lifting capacities ranging from 5 tons to over 1000 tons and can handle heavy loads efficiently for construction jobs.

Key Components of a Crawler Crane

The major components that make up a mobile crane include:

- Undercarriage: The undercarriage comprises a set of Crawler Cranes or legs that enable the crane to move on any ground conditions. Track shoes provide firm traction while traveling.

- Superstructure: It contains the crane's horizontal boom, counterweight, cab, winch and wire ropes. The superstructure rotates over the trackshell.

- Boom: It is the main lifting arm of the crane made from steel or aluminium. Booms come in sections that can be extended using winches.

- Jib: An optional telescopicextension is attached at the end of the main boom to reach farther locations.

- Counterweight: It is a heavy block placed at the rear/back of the crane to provide stability during lifting operations.

- Control Cab: An air-conditioned cab equipped with control consoles, joysticks and levers for the operator to maneuver the crane.

- Engine: Diesel engines in the range of 200-1000 HP power the movement of tracks and superstructure rotation.
