Where excavators once held sway materials handlers are now the weapon of choice for recyclers and, with the launch of its new DX250WMH-5, Doosan has just the solution.
Over the last 15 years, material handlers for demolition, scrap and waste processing applications have become one of the key pieces of equipment for metals and other material recyclers around the world. Where traditionally, scrap, automotive and other recyclers may have made use of excavators, these more specialised units have been found to be excellent replacements.
Compared to standard excavators, material handlers such as the new DX250WMH-5 provide recycling applications with increased mobility, efficiency and productivity, longer reach, improved safety and visibility for operators, as well as decreased emissions.
If a company is doing multiple tasks throughout the work day, for instance – such as unloading and loading trucks, sorting materials or moving the machine around – the ability to raise and lower the cab is a very convenient feature, and that’s just what the new Doosan DX250WMH-5 Material Handler provides.
Based on the manufacturer’s largest wheeled excavator – the 21 tonne DX210W-5 unit – the new Stage IV compliant material handler has been designed specifically for a wide range of material sorting and handling applications, including scrap metal and other solid waste and recycling industries, as well as logging.
This is a machine that’s been developed specifically for tasks in tough environments, with a specially configured boom and arm, front and rear stabilisers, and the increased visibility that a rear view camera display, in conjunction with that 2.5metre elevating cab, will afford.
Multiple Options
The market demands that material handlers operate as multi-taskers, which makes attachments a key consideration. If, for instance, you are loading, cutting or moving ferrous and non-ferrous materials then grapples and magnets are available. There’s also an optional generator as a turnkey solution, without any additional modification, which will provide power to those magnets.
Other factory-installed options include additional work lamps, cab guarding, frame guards, a fuel filter pump, a rotating beacon, an air compressor and solid tyres. For added durability, an optional V-guard protects the machine sides and components behind the doors.
Operators should find favour with the ergonomic joysticks and a steering wheel, whilst the machine comes equipped with two-way auxiliary and rotate circuit hydraulics. As a result, auxiliary attachments can be controlled via buttons on those joysticks or through an optional foot pedal.
Power is derived from a 6-cylinder, turbocharged Doosan DL06PA water-cooled diesel engine, providing an output (SAE J1995) of 129.4 kW (173.5 HP). It meets Stage IV emission regulations without the need for a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies. A special Doosan-developed system, Smart Power Control (SPC), improves machine efficiency while maintaining productivity through variable speed control and pump torque control, automatically adjusting RPMs according to the load being handled.
Power Modes to Match the Application
The SPC can be used with all four work modes available on the Doosan DX250WMH-5 material handler. These power modes help the operator to manage the balance of fuel consumption and machine power to the working conditions. The four selectable power modes include:
• Power+ (P+) mode: delivers the fastest work group speeds and greater power for those high demanding material moving applications
• Power (P) mode: provides exceptional power and superior performance for tough heavy lifting, quick truck loading and fast travel speed
• Standard (S) power mode: enhances the machine’s fuel consumption while delivering high performance in everyday lifting and moving of materials
• Economy (E) mode: helps reduce fuel consumption for low-demand applications and slows down machine movement for conditions that require more precise movements.
In addition to the four power modes, the DX250WMH-5 includes a lifting work mode, which provides increased pump torque, low engine RPM and an automatic power boost.
In the cab, a standard 7-inch colour LCD display provides helpful maintenance history and machine monitoring information. It also displays a video feed from the standard rear-view camera and/or an optional side view camera, which are uniquely placed to give even better visibility. A split screen mode displays the rear view camera and vital machine information at the same time. The feed from the optional side view camera can be reviewed independently or in a split screen mode.
DoosanCONNECT Telematics
DoosanCONNECT telematics is standard on the Doosan DX250WMH-5 material handler, and comes with a three-year subscription. The system provides locations and a full range of machine operational information to owners, dealers and the manufacturer itself. A simple user interface – accessible online via a web-enabled computer or smartphone – communicates the data to the interested parties, allowing them to reduce operating costs by better monitoring of equipment and the management of maintenance regimes.
Now covering over 70,000 of the company’s excavators, wheel loaders and articulated dump trucks (ADTs) worldwide, the first telematics service was launched in China in 2005. The DoosanCONNECT system is designed to increase efficiency in yard management and equipment operation through real-time data monitoring to check engine and hydraulic system parts of machines, and other construction equipment, and to provide information, mapping and visuals on their location and availability. Customers receive a monthly report on equipment operations to ensure efficient equipment deployment with detailed information on service hours and fuel consumption, and timely responses to filter and oil replacement.
