Product Description

SINOWAY SWD420S Bulldozer Features

As a monster manchine,SWMD420S challenges the competition head-on with its international class roller suspension and muscular push/pull power. Mainly used in large mining projects,SWMD420S has the power to adapt to tough working conditions and its top features include ROPS cab with FOPS function, central pressure measurement, central lubrication and automatic track tensioning.

Powerful Cummins turbocharged diesel engine reduces the quantity of parts by >25% and saves the maintenance time by >50% than like products, featuring strong power and high efficiency and energy-saving.

The high reliability power shift transmission and the planetary gear final drive feature high power transmission efficiency and high durability and productivity.

The new structure cylinder and the originally imported seals and hydraulic hoses for critical portions are adopted to greatly promote the service life and reliability. The external working valves make the maintenances easier.

The international brand instruments feature higher reliability and more accurate and distinct indications and realize electronic monitoring and out-of-limit alarm for the operation conditions of major components and for the parameters such as oil temperature, oil level, and water temperature.

The K-type air suspension traveling system and hinged chassis structure can effectively guard the drive system against the influence of impact load and improve the traction performance and life of the machine.

The full box-type main frame with application of high performance materials and high strength castings features high carrying capacity against impact load and bending moment to support the continuous high-strength working of machine under severe working condition and the high quality welds guarantee the life cycle of the main frame.
