Slewing Bearing for Concrete Pump Truck
Concrete pump truck is a machine that uses pressure to continuously transport concrete along the pipeline. It consists of a pump body and a delivery pipe. According to the structure, it is divided into piston type, extrusion type and hydraulic diaphragm type. The pump body is installed on the chassis of the car, and then equipped with a retractable or inflection boom to form a pump truck. The slewing bearing used by the concrete pump truck is generally a single-row ball slewing bearing, which needs to carry a certain axial force and overturning moment. The main function is to support and rotate, and to control the direction of the cantilever.
