Knuckle boom cranes and telescopic cranes have significant differences in structure, application scenarios, and operation.
Knuckle boom cranes and telescopic cranes have significant differences in structure, application scenarios, and operation.
Structural Differences
Telescopic crane: Often called a straight boom crane, its structure is similar to a truck crane, lifting goods via a winch, steel cable, and pulley system. The boom of a telescopic crane can extend, adapting to different working radius and height requirements.
Knuckle boom crane: Its boom is similar to that of a concrete pump truck, usually with three sections, the last of which can extend. The boom of a knuckle boom crane can fold, occupying less space, making it suitable for operation in narrow spaces.
Application Scenario Differences
Telescopic crane: Due to its simple structure, low cost, and ability to meet most working conditions, it holds a larger market share. It is suitable for use in open work environments, especially when long-distance lifting operations are required.
Knuckle boom crane: Because its boom can fold, it occupies less space and is suitable for operation in narrow or confined spaces, such as factories, warehouses, or situations requiring low-altitude operations. Knuckle boom cranes perform particularly well in environments with limited vertical space.
Operational Difficulty Differences
Telescopic crane: Operation is relatively simple, using a hoisting mechanism that winds and unwinds steel wire, making vertical lifting and lowering relatively easy.
Knuckle boom crane: Operation is more complex, requiring multiple hydraulic cylinders to work together, similar to the movements of a robotic arm, making operation more difficult.
