Slewing bearing is a key component used in construction machinery. The development and application of bearing technology directly affect the work efficiency of construction machinery.
Slewing bearing is an important part of construction machinery to with stand heavy loads, high speed rotation and complex working conditions.It acts as a connection and support for working parts, withstands static and dynamic loads, and can with stand radial and axial forces during rotation.The design and manufacture of slewing bearing is very important to improve the working efficiency of construction machinery.
The construction method of full rotary drill is to cut the pile with casing. The strong rotary torque of casing can twist off the pile and take it out with punch grab. According to the different construction conditions, it can be cleared by division cutting, whole pulling, heavy hammer cracking and multi-claw grinding.
