The performance of the DX300LCA has a direct effect on its productivity. Its new improved engine and new EPOSTM controlled hydraulic system have combined to create an unbeatable hydraulic excavator, with a cost/performance ratio that makes the DX300LCA even more appealing.
DOOSAN ENGINE(DE08TIS)
Doosan product gives high performance through in-house engine. Doosan engine (In-house) perfectly harmonized with the hydraulic system and provides strong power. Mechanical engine provides high resistance to moisture, dust, and bad fuel quality. The best engine power in the industry (193HP) provides stable working speed even in the heavy
workload situation.
HYDRAULIC PUMP
The Main pump has a capacity of 2 x 247 l/min reducing cycle time while a high capacity gear pump improves pilot line efficiency.
SWING DRIVE
Shocks during rotation are minimized, while increased torque is available to ensure rapid cycles
EXCAVATOR CONTROL
Improved Excavator control by New EPOSTM system. The brains of the hydraulic excavator, the EPOSTTM (Electronic Power Optimizing system), have been improved, through a CAN (Controller Area Network) communication link, these units are now perfectly synchronised.
The reliability of an item of plant contributes to its overall lifetime operating costs. DOOSAN uses computer-assisted design techniques, highly durable materials and structures then test these under extreme conditions.

TRACKS
The chain is composed of self-lubricating sealed links isolated from all external contamination. The tracks are locked by mechanically bolted pins.
INTEGRATED TRACK SPRING AND IDLER
The track spring and the idler have been joined directly to achieve high durability and improved maintenance convenience.
RELIEF CUTOFF
The pump continues to supply flow even when the maximum pressure on the system is reached due to severe working environments and large workloads. Relief cutoff technology of DX300LCA prevents transfer of unnecessary flow to maintain powerful working level at the maximum value while reducing consumption of fuel.
OPTIMIZED LEVER CONTROL & AUTO IDLE
When operator takes a break and leaves the control joystick fixed, both of the engine and the pump are kept in standby mode and prevents unnecessary fuel consumption.
PUMP MATCHING TECHNOLOGY
Engine & pump matching, the new technology of Doosan, fully resolves problems; low respones time of the system, unnecessary fuel consumption. Matching response time between pump and engine efficiently reduces unnecessary fuel consumption as well as exhaust fumes.
More space, better visibility, air conditioning, a very comfortable seat. These are all elements that ensure that the operator can work for hours and hours in excellent conditions
3 power modes for maximum efficiency

CONTROL LEVER
Very precise control of the equipment increases versatility, safety and facilitates tricky operations requiring great precision. Levelling operations and the movement of lifted loads in particular are made easier and safer. DOOSAN designed the DX300LCA by putting the operator at the center of the development goals. The result is significant ergonomic value that improves the efficiency and safety of the operator.
More space, better visibility, air conditioning, a very comfortable seat... These are all elements that ensure that the operator can work for hours and hours in excellent conditions.
