The use of continuous bucket wheel material, with the belt conveyor on the machine continuous stacking rail loading and unloading machinery. It is a special machine for bulk materials (bulk materials) storage yard, which is evolved on the basis of bucket wheel excavator. It can be used as a storage yard transportation mechanized system with unloading (ship) machine, belt conveyor and loading (car) unit. The production capacity can reach more than 10,000 tons per hour. The operation of bucket wheel stacker and retake machine has strong regularity and is easy to realize automation. The control mode includes manual, semi-automatic and automatic.
The boom type bucket wheel stacker is composed of bucket wheel mechanism, rotary mechanism, belt conveyor, tail car, pitching and running mechanism. The lifting slewing mechanism is composed of slewing support and driving device to make the boom turn around. In order to ensure that the bucket shovel can be filled when the boom is at any position, the rotation speed is required to realize automatic adjustment within the range of 0.01 ~ 0.2 RPM according to certain rules need use dc motor or hydraulic drive mostly.

The slewing bearing used by the stacker and reclaimer is generally a heavy-duty slewing bearing, and the tail end bearing needs to carry a large axial force and overturning moment. The main function is to support and rotate, and to control the direction of the cantilever. The slewing bearing used for front-end stacking and reclaiming generally carries radial force or axial force and a certain overturning moment, and its main function is to rotate.
Selecting the appropriate slewing bearing can effectively increase the bearing capacity, prolong the service life, and ensure the smooth and efficient operation of the equipment.
The motor drives the pinion to rotate, generates radial torque through axial motion, drives the slewing bearing to rotate, and makes the platform or mechanism connected to the slewing bearing rotate with the slewing bearing.

The reclaimer is a lifting device for heaped material, which needs to be transported from a stockpile for further processing. The diverse selection of models ensures all kinds of storage locations are catered to. These can visually resemble bucket excavators. Since swivel movements have to be carried out to remove a stockpile, our slewing bearings of varied dimensions are also put to use here.

Three row roller slewing bearings are widely used on heavy-duty machines which demand large working radius.
Product Detail
Three row roller slewing ring bearing has three seat-rings, which separate the upper, lower and radial raceway, via which the load of each row of the rollers may be specified. Thus it can carry different load simultaneously and its load capacity is the largest one of the four types.
- Structure:
Triple row roller slewing bearing has three different types:
no gear
external gear
internal gear
- Features
Triple row roller slewing bearings have following features:
Larger axial and radial dimension, compact structure
- Application
three row roller slewing bearings are widely used on heavy-duty machines which demand large working radius, such as bucket-wheel excavators, wheeled cranes, ship cranes, ladle turret, auto cranes etc.
Attached is the catalogue for triple row roller slewing bearing, you can choose the suitable slewing bearing according to your demand.
