Develon (formerly Doosan Infracore), Swanee, Georgia, has upgraded its compact equipment offering with the DX89R-7 mini excavator, which is now available in the United States and Canada.

The new DX89R-7 mini excavator replaces the DX85R-3 and includes many of its predecessor’s features while adding greater lifting capacity and horsepower, according to the manufacturer. This machine is equipped with a Develon engine and diagnostics tool and a reduced tail-swing feature, permitting more power in cramped, congested worksites.

“The new 9-metric-ton DX89R-7 excavator is a bridge between our smaller mini excavators and our crawler excavators,” says Thomas Lee, director of product management for Develon. “It gives our customers the flexibility of a mini excavator with more power and dig depth they may need without moving up to a larger machine.”

Performance
Powered by a Tier 4-compliant D24 diesel engine, the DX89R-7 provides increased productivity compared with its predecessor, the company says. Auxiliary hydraulic flow is included for operators who use hydraulic-powered attachments with the mini excavator.

The increased operating weight and the excavator’s new counterweight design provide better stability for increased lifting capacity, Develon says. This is particularly useful when using the excavator to lift and place objects. Traction force also is higher in the new DX89R-7 because of the machine’s higher weight, meaning customers can push material more efficiently with a dozer blade. The boom swing feature provides flexibility for DX89R-7 operators. A thumb switch on the left joystick controls the excavator’s boom swing. This can be helpful in confined spaces when the operator needs to dig next to an existing structure or obstacle, the company says.

Customers can configure the DX89R-7 with an optional long arm. The long arm provides nearly 2 feet of additional dig depth and reach. This can help reduce machine repositioning and improve cycle time when performing repetitive movements.

The new DX89R-7 features a quick coupler that can increase efficiency, Develon says. Quick-coupler piping comes standard for the new DX89R-7 mini excavator. Customers also can add an optional second set of hydraulics to operate multifunctional attachments, such as tilt-rotator accessories for mini excavators.

To make grading, leveling and backfilling as easy as possible, the dozer blade float feature allows the blade to follow the contours of the ground without operator input.
