Develon beefs up compact line with DX89R-7 mini excavator

Develon adds the new DX89R-7 mini excavator to its line of compact equipment, a beefier machine than its predecessor, now available in the U.S. and Canada.

Formerly Doosan Infracore construction equipment, Develon announces the next-generation, -7 Series mini excavator replaces the DX85R-3.

The reduced-tail-swing DX89R-7 features enhancements, such as greater lifting capacity and more horsepower, and is powered by a Develon engine and diagnostics tool.

“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 at 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.”

Like smaller -7 Series mini excavators, the DX89R-7 comes with an platform to improve structural durability and machine robustness. Powered by a Tier 4-compliant D24 diesel engine offering more horsepower, the DX89R-7 provides increased productivity from its predecessor.

An increased machine operating weight and the excavator’s new counterweight design provide better stability for increased lifting capacity. This is particularly useful when using the excavator to lift and place objects such as pipes, boulders or hardscape materials. Traction force is also higher in the new DX89R-7 due to the machine’s higher weight, meaning customers can push material more efficiently with a dozer blade.

The boom swing feature provides more flexibility for DX89R-7 operators. A thumb switch on the left joystick controls the excavator’s boom swing. This can be helpful when operating the excavator in a confined space, when the operator needs to dig next to an existing structure or obstacle.

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

The DX89R-7 can be paired with attachments, including buckets, quick coupler and thumb. The quick coupler significantly reduces the time it takes to switch attachments, which can increase the operator productivity and ensure the correct bucket is paired with the digging requirements. Quick coupler piping comes standard for the new DX89R-7 mini excavator.

Excavator owners can further increase the machine’s versatility by operating with approved attachments, such as augers, hydraulic breakers, plate compactors, rippers and grapples. Customers can also add an optional second set of hydraulics to operate multi-functional attachments. 

Similar to larger excavators, the new DX89R-7 comes standard with an 8-in. Smart Touch screen that enables operators to quickly read machine performance indicators and change machine settings. A rear-view camera can be viewed from the touch screen for enhanced job site visibility and safety.

The new DX89R-7 excavator has a swing-open tailgate and side-access hood, providing easy access to the excavator’s engine and pump package, valve bank, cooling system and hydraulic system.
