Quarrying
blade has been fitted with rounded edges and a higher spill guard. This makes loading even more efficient and has a direct impact on reducing cycle times and increasing productivity.
From the operator's point of view
“Our wheel loaders are mainly used to pick up material from the quarry face and to load trucks. I can safely say that with the DL420-7 the work has become much faster and the machine never lacks power. The loader is very stable, the hydraulics are smooth, which provides dynamic movements. The ability to control the direction of travel with the joystick is especially praiseworthy, especially when the work requires repetition of the same manoeuvres, for me this hits the bull’s
eye for loader operation. The operator comfort has certainly increased, the protection
against shocks is clearly noticeable, especially when you are
working a 10-hour day.
Another important improvement for me is the easy access to filters and components, which means that daily maintenance requires a minimum of effort,” mentions operator, Rafał Pawłowski.
The operator's cab is spacious and the steering is electrically controlled. All settings and information can be accessed via an intuitive 8 inch touchscreen, which is easy to read in all conditions. Safety was one of the most important aspects when designing the
DL-7 loaders. The operator's field of vision is increased by enlarged windows, and LED work lights in a 4 front, 4 rear
configuration provide excellent illumination, especially in the winter months.
From the owner’s perspective
“We work with relatively light material, such as sand, gravel and stone, but the quarry is quite steep and the terrain is bumpy, which means the machine is heavily laden during loading. With this workload, the average fuel
consumption of 13 l/h is a very good result. Since the delivery of the machine, we have used it for more than 2500 hours without a hitch, so I consider this to be an extremely successful investment. I am glad that I was the first in Poland to have the opportunity to test the capabilities of this excellent machine. When I choose Doosan, I get quality at a reasonable price. Without compromises," sums up Mateusz Wroński.
Like all Doosan DL-7 wheel loaders, another advantage offered by the DL420-7 is the factory-installed wireless fleet management system, DoosanCONNECT TMS 2.0, which provides extensive information about operating parameters, including work efficiency, via satellite and mobile networks. The standard warranty on all Doosan DL-7 loaders is 36 months/5000 hours, whichever comes first.
