About 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 concrete pump truck is transformed on the chassis of the truck. It is equipped with motion and power transmission devices, pumping and mixing devices, distributing devices and other auxiliary devices on the chassis.
The power of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power transfer case, and the hydraulic pump pushes the piston to drive the concrete pump to work. Then, the concrete is transported to a certain height and distance using the placing boom and delivery pipe on the pump truck.
Selection of slewing bearings
Single row ball slewing bearing
Application of slewing bearing
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.
Application principle of slewing bearing
The motor or reducer drives the pinion to rotate, and the pinion drives the slewing bearing to rotate, so that the upper mechanism connected to it rotates accordingly.
Why use a slewing bearing？
Selecting a slewing bearing with an appropriate structure can effectively increase the load, make the equipment run smoothly and have a longer service life.
