DEVELON, formerly known as Doosan construction equipment, has introduced its next-generation tool carrier models — the DL200TC-7 and DL250TC-7 — in the United States and Canada. These new models round out the 7 Series wheel loaders for the company.
Like their 5 Series predecessors, the DL200TC-7 and DL250TC-7 tool carriers have a parallel-lift linkage system that gives operators control over a variety of attachments in applications other than loading, such as lift- and place-type applications. The tool carrier’s lift arm design keeps the attachment level, allowing for 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,” said Bill Zak, wheel loader product manager. “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 change non-hydraulic attachments, including buckets — general purpose, light material or multi-purpose — and pallet forks.
With visibility down the center of the parallel-lift arms, operators can see the ground, truck or work area in front of the machine. The tool carriers also feature a viewable glass area, full glass door, large mirrors and optional LED work lights for visibility. A standard rearview camera provides an additional view of the machine’s surroundings and appears on the 8-in. Smart Touch display inside the cab.
Plus, with the exclusive Transparent Bucket option, operators can 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 information, as well as the rearview camera view.
The heating and air conditioning system has been redesigned from previous wheel loader generations.
Power and Precision
The hydrostatic transmission in the DL200TC-7 tool carrier delivers power, fuel efficiency and 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.
- Speed Management: Operators can adjust their maximum travel speed independently from engine speed.
Operators can also use the creep function to 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 adjust traction force to match jobsite conditions when digging, stockpiling and loading.
Load-sensing hydraulics support fuel usage by adjusting hydraulic flow to specific levels based on working conditions.
Lifting Large Loads
The DL200TC-7 and DL250TC-7 are equipped with large axles that help lift loads, and an optional additional counterweight is available for lifting performance. The new models also feature wide radiator fin spacing and a standard reversible fan that clears dust, dirt and other large debris to help prevent clogging.
The wheel loader’s durable box frame and articulating design delivers rigidity and load distribution. A deep front fender provides wheel coverage that helps protect the windshield, and the optional rear full fender supports stability.
A high-lift configuration is available for the two tool carriers, providing dump height for processing plants, scrap and recycling facilities and agricultural operations. Dump height is particularly useful for tool carrier operators who regularly load trucks and need lift height to dump material into the truck. The optional high-lift configuration provides an additional 18-in. of dump height.
Standard Technology Features
Operators can access standard technology features on the 7 Series tool carriers, like the telematics system. The features allow operators to monitor their fleet and manage maintenance. 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 promotes wheel loader stability while moving.
