D42-3 crawler bulldozer is equipped with working device controlled by PPC pilot proportional valve, K-type air suspension traveling system, global intelligent service system, and ROPS and FOPS, featuring advanced structure, high working condition adaptability, and high working efficiency. It’s especially applicable for the earthwork mining and rock stripping conditions for mining and construction projects

Technical Feature

KTA19-C525 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 imported 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.
