Doosan Wheel Loaders: DL420


From the beginning, Doosan has had great concern for machine operators. People need to work in a welldesigned and comfortable environment. The work area is spacious, with several places for storage. The checking and monitoring devices are comprehensive. There is an open view of the work area. For night work, operators are provided with powerful front and rear lighting.


DL400 features an intelligent, load-sensing hydraulic system. Two variable piston pumps provide the exact flow and pressure required and delivers a powerful, highly effective force, offering superior penetration of the hardest materials. The exceptional drawbar pull at the wheels, is reinforced further by providing limited-slip differentials as standard equipment. The engine offers high power and torque characteristics.


Every morning, when the operators commence work, they know that things will go smoothly- because Doosan has taken care of it. The product is soild. Operators know that they have significant reserves at hand and that they won’t have to push the machine to its limit. The Doosan DL400 wheel loader is designed and built to last. For Doosan, ‘reliable’ means availability, accessibility and simplicity.


A liquid crystal display conveys information to the operator relative to the ZF transmission. At the same time, it reports the nature of a problem (of one exists). When servicing the loader, a specialised apparatus can be used to adjust the clutch disks to compensate for their wear. Additionally, by connecting a lap top computer, a complete transmission diagnostic can be performed.
