The boom is the core component of lifting equipment (such as truck cranes, crawler cranes, marine cranes, knuckle boom cranes, etc.), enabling cargo lifting and positioning through telescoping, slewing, or folding. Its design directly affects the crane’s lifting capacity, working radius, and applicable scenarios.

Basic Components:

Main Boom: The foundational support structure, typically designed as a box-type or truss configuration, providing the primary load-bearing capacity.

Jib (Optional): Attached to the top of the main boom to extend the working radius or increase lifting height, suitable for specialized operations (e.g., high-rise building construction).

Telescoping Mechanism: Adjusts boom length via hydraulic or mechanical transmission, with some booms supporting multi-stage synchronous extension.

Connection Joints: Utilize high-strength bolts or pin connections to ensure structural stability.
