DEVELON, formerly known as Doosan construction equipment, has expanded its next-generation -7 Series crawler excavator lineup in North America with the DX1000LC-7. The 100-metric-ton conventional tail swing excavator is well-suited as a large earthmoving and excavating machine for heavy construction and infrastructure projects.

“The DX1000LC-7 is designed to serve a growing crawler excavator size class,” says Thomas Lee, director of product management at DEVELON.

The manufacturer says the excavator includes smart machine technology and a rugged design for maximum uptime protection. Features include a crossed-design swing bearing that distributes stress for machine uptime protection. With the aim of boosting the machine’s reliability and keeping it running longer, attention was given to reinforcing the excavator’s wear points. The excavator also includes a heavy-duty front design with additional reinforcement on key stress points for uptime protection.

Operators can choose the swing priority mode for bank cutting and when the swing angle is large to increase the swing speed and maximize productivity. The boom up function is prioritized when the swing priority is turned off.

The excavator’s exclusive D-ECOPOWER system is designed to help improve productivity and save fuel. The hydraulic system precisely controls oil flow and optimizes the engine’s available horsepower. The system’s efficiency not only improves productivity but also reduces fuel consumption.

Operators can choose between two modes: boom and swing. This allows operators to adjust the machine to best match the job at hand, giving priority to boom or swing movements. Boom priority is ideal in harsh conditions, such as digging over the front or dumping over the side of the machine. Swing priority works best in normal or light-duty digging situations.

In the cab, the machine is equipped with push-button start and high-quality interior fit and finish. It contains an eight-inch touch screen LCD monitor that is 30 per cent larger than previous models for high visibility and easy access. Ergonomic adjustments include newly designed foot pedals and heated seats.

Operators can configure the shortcut button on the joystick to their liking so they can adjust the wipers, mute the audio or control the camera. The button can also be used to activate the optional intelligent floating boom feature. This enhancement helps to increase operator effectiveness and keep the operator’s hand on the controls.

The optional 360-degree all-around view monitoring (AVM) camera system displays a full view of the machine’s surroundings, giving operators greater confidence when positioning and operating the machine in tight work areas. Five visual perspectives can be seen from the separate AVM monitor: top view, rear view, top+right view, rear+corner view and 3D view.

Additional DX1000LC-7 excavator options include a hydraulic removable counterweight, which is helpful if the customer needs to transport the machine.

An optional auto-lube system makes daily maintenance simpler and enhances uptime protection.

The excavator also comes with unlimited access to the DEVELON Fleet Management telematics system. The system allows equipment owners and fleet managers to remotely monitor machine location, hours, fuel usage, engine idle versus work time, and error codes, as well as engine and hydraulic temperatures. Machines can be monitored via an online account. In addition, dealers can use the system to provide improved customer support by responding to machine warning messages and alerts, troubleshooting machine issues, and then sending a field service vehicle to deliver the proper parts and help with repairs.

The 629 hp (469 kW) excavator has an operating weight of 220,903 lb. (100,199 kg), with bucket breakout force of 88,185 lbf. (40,000 kgf), arm breakout force of 78,850 lbf. (36,220 kgf), a bucket capacity of 7 cu. yds (5.4 m3), maximum digging depth of 28 ft. 10 in. (8.8 m), and maximum digging reach: 45 ft. 11 in. (14.3 m).
