The DL200TC provides outstanding visibility down the center of the lift arms, which allows the operator to see the ground, truck or work area in front of the machine when placing loads. In addition, the parallel-lift linkage system keeps the work tool flat as it is lifted rather than rolling back, an advantage when lifting pallets and other loads that need to stay level.
Built around a Tier 3 compliant, 143 horsepower, 6-cylinder Doosan diesel engine, the DL200TC has an operating weight of 25,708 pounds with a standard 2.6-cubic-yard bucket. Dump height is 8 feet 11 inches, and dump reach is 3 feet 1 inch.
Bucket breakout force is 23,149 pounds with a pin-on bucket. Static tipping load is 18,913 pounds with a straight frame and 16,272 pounds at the maximum steering angle of 40 degrees. The DL200TC can be equipped with an optional quick coupler in order to make changing work tools easier.
Four forward speed ranges provide maximum speeds of 4.1, 7.5, 14 and 21.7 mph. Three reverse speed ranges offer maximum speeds of 4.5, 8 and 15.5 mph.
Like all Doosan wheel loaders, the DL200TC features a full powershift transmission with manual, automatic and semiautomatic (with “kick down” for first gear) modes. Transmission and engine operation can be easily diagnosed by connecting a laptop computer.
Hydraulically controlled, multi-plate wet disc brakes and dual brake circuits provide positive braking power. A spring-applied/hydraulically released parking brake is mounted on the front axle to prevent the loader from rolling after engine shutdown.
An optional electric-powered emergency steering system backs up the hydraulic power steering system in case of a malfunction, and a safety device prevents starting the engine when not in neutral. Optional front and rear axle limited slip differentials ensure positive traction in wet or soft conditions.
The DL200TC provides operators with outstanding visibility and low cabin sound levels. A roomy cabin, powerful heating and air conditioning system, tilting/telescoping steering column, ample storage space and a comfortable seat also help to reduce operator fatigue. An optional load isolation system provides smoother travel with a loaded bucket.
All routine maintenance on the DL200TC can be performed from ground level. Centralized hydraulic check ports and easily accessible drain valves for engine oil and coolant simplify routine maintenance. Remote greasing lubrication ports allow front pins to be lubed from the outside of the machine. The transmission oil filler pipe is located near the articulation joint for easy access and sight gauges for hydraulic oil and coolant levels allow easy daily checks while reducing the risk of contaminants entering the systems. In addition, the radiator fan can be reversed from the cabin to quickly clean out the radiator and hydraulic oil cooler in dusty environments.
Other options include a single lever control for travel functions and front-mounted attachments; and a hydraulically driven, variable-speed engine fan. The variable-speed fan features an electronic thermostat that constantly monitors engine coolant and transmission oil temperatures.
