Develon, formerly known as Doosan Construction Equipment, introduced its next-generation tool carrier models: the DL200TC-7 and DL250TC-7 in the U.S. and Canada. The new models round out the -7 Series wheel loader introductions for the company.
Improved Productivity with Parallel-Lift Linkage System
Like their -5 Series predecessors, the DL200TC-7 and DL250TC-7 tool carriers have a parallel-lift linkage system that gives operators precise control over a variety of attachments in applications other than loading, such as lift- and place-type applications, according to a press release. The tool carrier’s lift arm design keeps the attachment level, allowing for faster lifting and placing of materials.
“We’ve incorporated performance and design elements, like enhanced visibility, into our -7 Series tool carriers to help operators on jobsites,” wheel loader product manager Bill Zak said. “Our tool carrier models can improve an operator’s ability to load, unload and move materials, reducing the need for additional equipment and enhancing productivity.”
The DL200TC-7 and DL250TC-7 may be equipped with an optional hydraulic quick coupler to easily change non-hydraulic attachments, including buckets — general purpose, light material or multi-purpose — and pallet forks.
Increased Visibility and All-Day Comfort
With increased visibility down the center of the parallel-lift arms, operators will be able to clearly see the ground, truck, or work area in front of the machine. This leads to more precise work and a safer work environment. The tool carriers also feature increased glass area, full glass door, large mirrors, and optional LED work lights to improve overall visibility.
Moreover, a standard rearview camera provides an additional view of the machine’s surroundings and appears on the 8-inch Smart Touch display inside the cab. WIth the Transparent Bucket option, operators can also get a supplemental view “through the bucket” from an in-cab display. The wheel loader cab offers relocated, intuitive controls, and the Smart Touch screen displays all important information, as well as the rearview camera view. The heating and air conditioning system has also been redesigned from previous wheel loader generations to help operators stay comfortable.
The hydrostatic transmission in the DL200TC-7 tool carrier delivers more power, better fuel efficiency, and improved precision. Key features of the hydrostatic drive include:
- Dynamic Braking: When operators remove their foot from the travel control pedal, the system will automatically reduce the flow of oil, causing the machine to slow. This leads to less wear on the brakes and reduced energy consumption.
- Speed Management: Operators can adjust their maximum travel speed independently from engine speed.
Operators may also use the creep function to easily fine-tune their loader’s position without pressing the accelerator pedal.
For more control when doing precision work, the variable speed control offers seven preset speeds within first gear. Using the traction control management system, operators can easily adjust traction force to match jobsite conditions for efficiency in digging, stockpiling, and loading applications. Load-sensing hydraulics improve fuel efficiency by adjusting hydraulic flow to optimal levels based on working conditions.
Lift Large Loads with Ease
The DL200TC-7 and DL250TC-7 offer stronger, larger axles that help lift larger loads, and an optional additional counterweight is available for added lifting performance. The new models also feature wider radiator fin spacing and a standard reversible fan that clears dust, dirt, and other large debris to help prevent clogging. A deeper front fender provides additional wheel coverage that helps protect the windshield, and the optional rear full fender improves stability.
A high-lift configuration is available for the tool carriers, providing additional dump height for recycling facilities. Added dump height is particularly useful for tool carrier operators who regularly load trucks and need additional lift height to efficiently dump material into the truck. The optional high-lift configuration provides an additional 18 inches of dump height.
Telematics Comes Standard
Operators improve their productivity with standard technology features on the -7 Series tool carriers, like the telematics system. It makes it easy for owners to monitor their fleet and manage maintenance to reduce operating costs. Using a smartphone, tablet, or computer, owners can check machine location, operating hours, fuel usage, engine idle versus work time, error codes, engine, and hydraulic oil temperature and various other data points. An improved Load Isolation System boosts wheel loader stability while moving, which can reduce cycle times, increase productivity, and boost fuel efficiency.
