Doosan is launching the new DL420CVT-5 Stage IV compliant wheel loader, the first model in the Doosan wheel loader range to be equipped with a Continuously Variable Transmission (CVT). A CVT transmission is composed of a hydraulic motor combined with a hydraulic pump which provides a smooth and continuous speed variation. The CVT design combines the benefits of a mechanical transmission and a hydrostatic transmission in the same machine. It allows the DL420CVT-5 to automatically transition from hydrostatic power at low speed to the mechanical system to operate at higher speeds. nike air max flyknit By combining the two types of transmission, the new CVT technology ensures high loads can be carried at low engine speeds with high dynamics for an optimum wheel loader operating cycle. nike huarache The DL420CVT-5 therefore provides an increase in machine performance for operators working in digging, loading and lifting applications. With a maximum bucket capacity of 4.2 m3, the new Doosan DL420CVT-5 wheel loader is intended to meet a wide range of material-handling needs from loading and transporting granular material (such as sand and gravel) to industrial, construction, demolition, mining and quarrying applications. For most tasks, operators will utilise the hydrostatic part of the transmission, which offers greater fuel efficiency in low-speed applications. adidas yeezy boost The combination of the two transmissions is automatic and fully transparent for the operator. The complete driving range, forwards and in reverse, is controlled by the CVT system. Low engine speeds ensure a high efficiency and the highest driving comfort irrespective of the traction speed. The power splitting continuously variable technology facilitates moving off softly and hydraulically. Furthermore, with the CVT, a fuel saving of up to 15% can be achieved. The ability to split hydrostatic and mechanical power has allowed Doosan to move to the Scania DC09 engine in the DL420CVT-5, as the CVT system maintains the machine’s efficiency even at low engine rpm. With an output of 232 kW of power at 1800 rpm, the Scania DC09 engine provides generous torque at low rpm and meets Stage IV emission regulations without the need of a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies. The engine compartment door size has been increased to provide easier maintenance of engine area. timberland 6-inch premium The exhaust and after-treatment system for the engine is installed on the left-hand side of the machine, whilst the components for maintenance are grouped on the right-hand side. All the daily checking of gauges can take place from ground level to ensure it is a quick and safe process. bottes ugg bailey button pas cher The breakout force and high traction allow the DL420CVT-5 to tackle the hardest materials, with a powerful hydraulic system that ensures that work is quick and efficient. Combined with the power provided by the Scania DC09 engine, these features gives the DL420CVT-5 excellent penetration power, ensuring an optimum bucket load in each cycle.
