 Wheel loader : DOOSAN DL300A
A Powerful Wheel loader with
Novel Features

The new DL300A wheel loader has all the advantages of the Increased production due to the use of powerful DE08TIS engine and the excellent synchronisation
previous loaders. This logical new step provides real added of the drive train with the hydraulics system.
value to the operator.
Improved ergonomics, increased comfort and excellent all round visibility ensuring safe and pleasant working conditions.
The new DL300A was developed with the concept of “providing
optimum value to the end user.” In concrete terms, this Improved reliability through the use of higher performance new materials, the development of new computer-assisted structural
translates, into : design techniques and by intensive and systematic test programs. All of these combine to increase the life of vital components and
reduce operating costs.

Reduced maintenance increases the availability of the loader and reduces operating costs.
PERFORMANCE
The DL300A is a machine that 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.
As a result, the hydraulic system is able to multi-function with power and speed.

Full Auto Transmission

The electronic powershift transmission is particularly smooth and

have resulted in the emergence of a highly efficient and very working conditions. Built-in electronic controls enhance
powerful engine that boasts the highest power in its class. productivity and durability.

Axle
Improved internal oil flow greatly reduced the
temperature difference between the hub and the
differential, as well as prevents premature disc wear
due to overheating of the internal hub compone nts.

LSD (Limited Slip Differential)

The standard equipment LSD allows easy driving
through soft and swampy grounds.

Increased Axle Durability

The brake discs have been repositioned to the rear part of the reduction gear where the rotation speed
is lower. As a result, the discs are exposed to lower rpm’s and heat generation is reduced and the life
span of the discs is greatly extended. Automatic disc clearance regulator has been intergrated into the
design and the disc clearance is maintained at the optimum level at all times as the discs wear out.
This prevents any lag in brake response. Another convenient feature is that brake disc wear can easily
be measured without disassembling the hub.

The brake piping has been redesigned into the axle housing and is protected from damage from
external shock as the machine drives over rough terrain.

COMFORT
From the beginning, Doosan has had great concern for machine operators. People need to work in a well-
designed 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.

MAINTENANCE
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.
