New handlers and four-tine grapples are designed specifically for material sorting and handling applications.
The equipment company Doosan Infracore Construction Equipment America, West Fargo, North Dakota, has introduced three material handlers and four-tine grapples. The first model being launched is the DX225MH-3 material handler. Doosan says additional material handlers will include the DX300MH-5, a larger model with steel tracks, and the DX210WMH, a wheeled model.
Doosan says that the new material handlers are being built specifically for material sorting and handling applications. Previously, dealers converted Doosan crawler excavators or wheel excavators into material-handling machines, according to the company.
Doosan says its material handlers were developed in-house to meet the demands of material handling companies. Each model is based on a tested excavator model and is factory-fitted with cab risers for increased visibility, the company says. Other features include a straight boom and droop nose arm designed for improved reach, lift height and placement, as well as improved machine guarding, the company says. Dual-boom cylinders and under-mount arm cylinder placement are intended to provide excellent lifting capabilities.
The company reports that its cab riser is designed to provide better all-around visibility to the attachment and work area. Standard fixed risers for the DX225MH-3 are 4 feet, and 6 feet for the larger DX300MH-5. A 6-foot fixed riser is available as an option on the DX225MH-3. Doosan says the fixed risers can easily be lowered for transport with a self-contained, electronically powered hydraulic system.
Available as an option for the DX225MH-3 and DX300MH-5 is a 6.5-foot hydraulic cab riser. The 6.5-foot hydraulic cab riser is standard equipment for the DX210WMH.
To maximize the versatility and productivity of the material handlers, Doosan says the new equipment can be paired with a grapple for material handling applications. The 360-degree hydraulic rotating four-tine grapples feature a semi-closed tine design for a firm grasp on most materials. The tines are constructed with AR400 high-strength, abrasion-resistant steel for increased durability, and the tine tips are replaceable for easier maintenance.
A five-eigths-cubic-yard grapple is approved for use with the DX210WMH and the DX225MH-3, while a 1-cubic-yard grapple is approved for use with the DX300MH-5. Connecting grapples to Doosan material handlers is fast and easy with a hose kit and mount, the company says.
Four power modes are available for the Doosan DX225MH-3 and DX300MH-5 material handlers to help operators manage the balance of fuel consumption and machine power to the working conditions. The four selectable power modes include:
- Power+, with the fastest work group speeds and greater power for high-demanding material moving applications;
- Power, with power and superior performance for tough heavy lifting, quick truck loading and fast travel speed;
- Standard power, with enhanced fuel consumption and high performance for everyday lifting and moving;
- Economy, which helps reduce fuel consumption for low-demand applications and slows machine movement for precision.
The DX210WMH material handler is available with three selectable power modes:
- Power mode;
- Standard power mode; and
- Economy mode.
In addition to the power modes, the Doosan DX225MH-3 and DX300MH-5 material handlers offer a lifting work mode providing increased pump torque, low engine RPMs and an automatic power boost, Doosan says.
