OPERATOR COMFORT? The new DL450-3 leaves the competition behind, with technologies that reduce fuel consumption. Doosan has placed comfort at the very centre of its design priorities for the DL450-3. More space, better. In manual mode, the operator can use a foot switch to lock the differential completely. Alternatively, it can be. Doosan wheel loaders meet the toughest requirements - yours. Operating Weight; 9' 0' Dump Height; 22,481 lbf. Handles tough materials and moves larger loads. 344.6 hp Engine; 56,527 lb. Choose manual mode for more control or automatic mode for easier operation.

“The operation has been complex since the customer before deciding by our loaders, has wanted to testar others of diverse marks, which for us has been a big satisfaction” comments Alfredo Pozueta, director Retail of Centrocar. “The decision of the group to our machine based to the relation quality, price, consumption and productivity of the model DL450.

Centrocar Had sold previously other three loaders Doosan of this same model to another important company of the same sector, that are operating in the port of Santander, with which had the guarantee that the loaders Doosan DL450 was ideal for the type of tasks and the needs required. It is difficult to achieve better guarantee that have the machine working in the same application with incredible results”. The loaders DL450 offers an excellent productivity thanks to his impressesive strength of push what allows to work with the hardest materials. On the other hand, his high power of traction enables it for a simple penetration in silos of materials. With his powerful hydraulics system, the operator works with rapidity and power.

The engine Common Rail Cummins QSM 11 presents some characteristics of power and of pair of excellent strengths. With his four valves by cylinder and his electronic control, optimises the combustion and reduce the broadcasts, minimising like this the pollution. The increase of the pair of strengths allows an efficient use of the power by means of the hydraulics system. A pair of intense strengths supposes a wide degree of manoeuvrability of the loaders when displacing. The engine has of two ways of operation: ‘Strength' or ‘Economic'.

The automatic transmission softens the handle and optimises the relations of change, avoiding shakes, as well as maximizando the confort for the operator. The strength of traction is optimum under all the conditions of work. The combination of such characteristics allows that the loaders can keep a high speed in all the terrains and favours the excavation, optimising like this the filled of the hunt in each cycle. The transmission has of three ways of operation: Manual, automatic semi-automatic (automatic, with variation by pressesure in the accelerator ‘kick down' for the first course). The bridges ZF are endowed of a differential with car-blockade in the leading and rear parts. Said automatic differential provides the power of maximum traction and a simple driving on soft terrains and fangosos. Also it reduces the risk to skate and the wear of tyres.

The disks of brake in the cubes of the wheels, with the gears reductores reinforced with metal, ensure long hours of operation and a maintenance reduced. Instrumented with stabilizer of load of series. This system is ideal for all the situations of load and trip. It increases the productivity and the confort of the driver. Likewise, it minimises the quantity of material disperse around. The geometry or cinematic in Z is very robust and is designed for heavy loads. Few mobile pieces, efforts reduced, simplicity, everything contributes to a greater stability of the loaders.

This geometry allows movements very fast of the hunt and ensures a correct angle in all the situations. Has loaned special attention to the design and the manufacture of the structural components. To ensure a long useful life of the main structures, all the structural components, such as the chassis, the articulations and the arm of izado, have been manufactured by means of a rigorous method.

After his modelado have to happen intense proofs, in laboratory and on the terrain, during which simulate extreme conditions, with the end to increase constantly the level of reliability of the loaders. “All this more the guarantees of the equipment and the service of the distributor of the zone did that the scales bent to the mark Doosan and Centrocar, ” concludes Alfredo Pozueta.

Performance DL450(Tier2 E/G) features an intelligent, load-sensing hydraulic system. Two variable piston pumps provide the exact flow and pressure required to deliver a powerful, highly effective force, offering superior penetration of even 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.

As a result, the hydraulic system is able to multi-function with power and speed.
