Doosan launches new wheel loaders

London, April 24, 2012

Doosan, a global construction and engineering company, has launched a new range of wheel loaders for markets in the Middle East and Africa region.

Building on the design of the previous Mega range, the new Doosan DL250A, DL300A and DL420A wheel loaders offer several improvements for better performance, greater operator comfort, easier handling and serviceability, as well as increased durability, a statement said.

With bucket capacities ranging from 2.5 to 4.5 cu m, the new DLA wheel loaders are intended to meet a variety of material-handling needs from loading and transporting granular material to industrial, mining and quarrying applications.

The new DL250A loader is powered by a Doosan Tier 1 diesel engine while the DL300A and DL420A models are driven by Doosan Tier 2 engines, all of which are less sensitive to fuel quality than Tier 3 engines, whilst still offering reduced fuel consumption and emissions.

The width of both the lift arm and the tilt lever on the DL250A wheel loader has been increased as well as the dump height increased to 2865 mm at the 50-degree maximum tilt angle.  All three wheel loader models offer higher static tipping loads at maximum reach with a straight frame: 11000 kg (DL250A), 14800 kg (DL300A) and 17900 kg (DL420A), according to the statement.

High operator comfort

The new ROPS/FOPS certified cab offers industry-leading operator comfort through a combination of increased space (6 per cent more volume in the DL250A and 11 per cent more in the DL300A and DL420A models); better visibility due to a wider front glass section; better air conditioning with a 30 per cent increase in air nozzles; a new instrument panel; a new layout for controls and switches and improved storage areas.

A new cab design offers better protection for the machine and operator thanks to larger mud guards, new metal grilles, new fenders, improved hand rail and step designs and a new roof cover.

New ZF axles

The new wheel loaders feature new versions of the ZF axles previously used on the Mega models.  The DL250A features the MT-L3085 version II axle in the front and the MT-L3075 II axle at the rear.  The MT-L3085 II is used for the rear axle on the DL300A with the ZF MT-L3095 II axle on the front. The latter is also used for the rear axle on the new DL420A, while the ZF MT-L3105 II axle is on the front.

All axles are equipped with a new breather system intended to prevent clogging from dust and sand, which can raise the temperature of the axle oil and damage seals on the axles.

Easier servicing and maintenance

In the DL250A wheel loader, the radiator grille opens wider for better access, while the swing-out fan on the DL300A and DL420A simplifies maintenance. The DL250A feature a new cooler while, in all three models, the air conditioner condenser is assembled with the coolers for better protection.  In the DL250A, the air conditioner condenser can be accessed directly by lifting the grille.  In the DL300A and DL420A, the air conditioner condenser can be tilted backwards to simplify cleaning.

The air cleaner features a larger filtration area enabling increased service intervals of 1500 to 2000 hours for the filters.  The covers for the air cleaner are latched and easier to open. – TradeArabia News Service
