Improvements have been made to the engine, performance and reliability.
The DX225LL-5 log loader replaces the Tier 3-compliant DX225LL model. The DX225LL-5 features a Tier 4 non-DPF Doosan engine. The operator can select from the machines’ electronic power optimizing systems (EPOS) that provides four work modes to best match the application. Doosan have also added an auto-shutdown system for use during non-working conditions. When configured, the feature will shut down the log loader’s engine when the pre-set idle time is met.
Uptime has been improved with heavy-duty thick steel doors and panels to guard components. A fully guarded, heavy-duty upper structure is designed specifically for forestry applications such as log loading, timber harvesting, forestry access road construction and maintenance, mill/yard operations and reforestation/fire control. Doosan has enhanced heel, arm and boom cylinder guarding. It has a high and wide undercarriage for improved ground clearance above stumps. The undercarriage’s track includes heavy-duty links with double grouser shoes, rock guards and full-length track guiding guards. Heavy-duty top rollers include special clean-out brackets to make routine maintenance easier.
When configured for log loading, the excavator has a durable boom, arm, and live heel and may be paired with a Doosan log grapple. Operators can rotate the Doosan log grapple 360 degrees to precisely place logs in truck-loading applications. A hydraulic tilting cab feature provides improved transportation. Inside the cab, operators have a standard air suspension seat, simple controls, air conditioning with adjustable air flow and improved foot space. Optional LED front and rear work lights are mounted to the cab to provide a well-lit area before sunrise or after sunset for improved visibility. A standard rear-view camera and optional side-view camera have been added to further enhance operator visibility. A 7-inch colour LCD screen, operators can easily monitor the log loader’s engine rpm, fuel consumption, battery voltage, front and rear hydraulic pump pressure and other critical machine data. The screen also displays the rear-view and optional side-view camera.
The DX225LL-5 also includes an optional side-entry forestry cab certified for Oregon OSHA and British Columbia WCB standards. The forestry cab is built with a guarded polycarbonate front window, side and rear windows, as well as a rear secondary exit. Additional options include a straight travel pedal, which allows the operator to travel in a straight line more easily; block heater or diesel-powered coolant heater for cold-weather starts; and additional LED lights for improved visibility.
A road builder configuration is available to create access roads to the logging area, remove stumps and install culverts. The road builder is similar to a log loader but is not designed with a cab riser. It comes with an excavator boom and arm configuration. A pattern change valve is available to quickly switch control patterns from SAE to ISO controls.
