China Factory Drectly Provide Track Roller Excavator Track Bottom Lower Roller
As the main load-bearing structural component of tracked rotary drilling rigs, especially in large tonnage tracked rotary drilling rigs, the design and manufacturing quality of the supporting wheels directly affect the overall safety of the drilling rig. The working conditions of the tracked rotary drilling rig are complex, and under some special lifting or lifting conditions, only a portion of the supporting wheels are subjected to force. Therefore, the arrangement of the supporting wheels is in the form of sparse middle and dense ends. In order to meet the gradually increasing weight of the tracked rotary drilling rig, the number and structural parameters of the supporting wheels increase accordingly. The supporting wheels are installed at the bottom of the crawler frame and form rolling with the upper and lower surfaces of the crawler plate when walking, Its installation form is mostly open in small tonnage, and closed in large tonnage
