DX55W Doosan Excavator Specs & Dimensions - (2019 - 2023)

DX55W Overview

The new DX55W hydraulic excavator has all the advantages of the previous model, and now offers additional added value to the operator. The new DX55W was developed with the concept of providing optimum value to the end user. In concrete terms, this translates into :

Performance DX55W

DX55W ensures best performance with powerful excavating force and high-tech hydraulic system for better operation efficiency at any work site! Excellent performance is its basic feature! Its excellent performance with safety and convenience taken into account will help safe and convenient operation.

Maintenance DX55W

The most advanced technology developed by Doosan was integrated into the DX55W excavator providing powerful performance and simple, easy maintenance. This provides the operator with convenient maintenance check points and maximizes the work efficiency of the DX55W.

Radiator

The large-capacity radiator provides excellent performance in severe and continuous operations. The assemblable dust net on oil-cooler front side prevents overheating from filth.

Higher gradability and work capability

Thanks to the strong driving force based on high performance engine power and the highest swing limit angle in the same class, the product shows distinguished capability in working on the slope.

Undercarriage Design

A rigid, welded frame provides excellent durability. Efficient hydraulic lines routing, transmission protection and heavy duty axles make the undercarriage perfect for your excavator applications. Both outriggers and dozer blade are pin type for maximum flexibility. An optional work tool restraint bar is available.

Drive

Fully hydrostatic driven, 2 speed mechanical shift transmission, variable displacement, high torque, axial piston motor, foot pedal controls provide smooth travel, hub reduction type front steering axle and rear rigid axle.

Undercarriage

Heavy-duty frame, all-welded stress-relieved structure. Top grade materials used for toughness. Specially heat-treated connecting pins. 12-16.5-12PR(10)RT tubeless single tires, front axle oscillating hydraulically (+/- 5°).

Comfortable Operating Area

The internal operating controls are arranged in a convenient and ergonomic fashion. This allows for maximized operating efficiency. A larger capacity air-conditioning system has been installed for operator comfort in all seasons. The open and spacious cabin provides the operator with a wide field of view for the best possible working conditions.

Operator's Cab

A roomy, independent, shock and noise-free operator's cab, four-side safety glass windows plus all-round visibility. Front window slides up and slides on all sides and side window can be opened for ventilation, fully adjustable suspension seat. Air conditioner. ISO standard cab.

Boom swing

The convenient boom swing function provides the ability to work in very narrow areas. The newly designed swing bracket and the boom swing cylinder size ensures powerful and stable boom swing performance.

Main control valve

The machine can be precisely controlled in the single and complex operation. For complex operation, the circuit that ensures the optimal front operation is adopted. Thanks to boom holding function, it prevents the boom from self-lowering.

Hydraulic Cylinders

High-strength piston rods and tubes are used. A cylinder cushion mechanism is provided for the boom and arm cylinders to ensure shock-free operation and extend the life of the cylinders.

Swing Mechanism

High-torque, axial piston motor with planetary reduction gear bathed in oil. Swing bearing is single-row, shear type ball bearing with induction-hardened internal gear. Internal gear and pinion gear immersed in lubricant. A two position swing lock secures the upper structure for transportation.

High-Output Air-Conditioner and Defroster

The air-conditioner capacity has been greatly improved and new filters have been installed at the intake and fresh air stages. A defroster is provided at the front window to prevent the front windshield from becoming frosted in the cold season resulting in safer operation.

Enlarged Entrance and Exit

As entrance and exit are enlarged, accessibility is improved for getting on and off the vehicle. Since the front workspace is maximized, the inconvenience in operating equipment is minimized.

Air Breather

The mounted large-capacity air breather protects the pump from possible damage that may be caused by cavitations. Since only the internal element instead of the entire can be replaced when exchanging, it is more practical.

Reliability DX55W

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, and tests these under extreme conditions. Durability of materials and longevity of structures are our first priorities.

Strengthened Boom

The shape of the boom has been optimized by finite elements design, allowing uniform load distribution throughout the structure. This combined with increased material thickness means improved durability and reliability by limiting element fatigue.

Arm Assembly

In the arm assembly greater strength has been gained by using cast elements and reinforcement around the bosses to give increased life.

Easy Maintenance

Access to the various radiators and coolers is very easy, making cleaning easier. Access to the various parts of the engine is from the top through side.

Control 2 Implement Levers

Travel lever pedal pilot pressure control type. Right lever is boom and bucket control lever, left for swing and arm control.
