Installation and uses of the three main structures of crawler cranes
Thread Content
A crawler crane is a boom-type rotating crane that moves using crawlers. It has advantages such as good adaptability, wide applicability, and portability. It is widely used for operations such as lifting, digging, and piling at construction sites. It is composed of a rotating boom, a turntable, a chassis, etc. Rotating boom: Composed of multiple components, it is telescopic and installed at the front end of the turntable; a wire rope pulley system is used at its top to provide suspension and support, thereby enabling amplitude variation. Turntable: Installed on the chassis, it transfers the weight borne by the turntable to the chassis, ensuring that the turntable can rotate freely. Chassis: It includes the traveling mechanism and the traveling apparatus; the traveling mechanism controls the direction in which the crane moves, while the traveling apparatus is composed of tracks, idler wheels, sprockets, and track rollers.
