About  Crane Machine

Crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. Also known as overhead crane, aerial crane, crane.

The main features of the tire crane are: its driving cab and the lifting control room are combined into one, which is evolved from a crawler crane (crawler crane), and the crawler and walking bracket of the traveling mechanism are turned into a chassis with tires. It eliminates the disadvantage that the crawler crane (crawler crane) crawler shoes cause damage to the road surface, and belongs to material handling machinery.

Overhead cranes are hoisting equipment that is horizontally placed over workshops, warehouses and stockyards for material hoisting. Because its two ends sit on tall concrete columns or metal supports, it is shaped like a bridge. The bridge of the bridge crane runs longitudinally along the track laid on the elevated on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of hoisting machinery.

Some of the working characteristics of lifting equipment are intermittent movement, that is, the corresponding mechanisms for taking materials, moving, and unloading in a working cycle work alternately. The development and use of cranes in the market are becoming more and more extensive.

Selection of slewing bearings

Heavy duty slewing bearing

Application of slewing bearing

The slewing bearing used by the crane is mainly heavy-duty slewing bearing, which is required to carry a large axial force and overturning moment. The main function is to support the upper mechanism and control the rotation of the upper mechanism.

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 bearing capacity, have a longer service life, and ensure the smooth and efficient operation of the equipment.
