21ton Hydraulic Tracked Crawler Excavators with Long Reach Boom

Product Description

Product Description
The Cummins B5.9 engine produces high power output. Sinoway has harnessed this power for the six working modes of the excavator. Perfectly match these work modes to the job at hand and even the least experienced of the operators will find they can work faster and complete more in less time.
Where intelligence meets brute force.Negative flow hydraulics direct the engine's power to ensure hydraulic pump flow
continually adjustable for smooth, quick and efficient operation.Engine power and hydraulic pump flow are automatically reset to adjust for the load attachment, helping to maximize the efficiency of the machine.
The SWE230LB 's tough and reliable structure provides increased strength, reduced wear, and improved transmission of power to the ground drive.
Ergonomically designed controls, clear and informative displays, increased visibility, and exceptional comfort increases operator efficiency and safety. The easily accessible service points ensures important daily servicing and routine maintenance gets done.
The boom and arm structures are designed with large cross-sectional supports and incorporates one-piece steel castings. This solid engineering guarantees long-term durability and high resistance to bending and torsional stress. Standard rock-guard plates and vertical guards protect the arm in rocky digging conditions and tough
environments.
The upper structure is strongly reinforced by the use of an H-beam in the high cross section of the main structure providing even weight distribution and increasing stability.The platform's collision protection system has been welded into place to improve its strength, rigidity and overall service life.
