DEVELON Launches New Generation DX27Z-7M Mini-Excavator for Brazil

Published: 11/9, 2023

DEVELON (formerly known as Doosan Construction Equipment) has launched the new DX27Z-7M 2.8t Stage V compliant mini-excavator for the Brazilian market. This model provides a larger working range with higher lifting capacities and digging forces, as well as the latest version 3.0 of the DEVELON Fleet Management system as standard equipment.

Featuring the new shared global styling for next-generation DEVELON mini-excavators, the DX27Z-7M’s novel platform design and new upper structure provide increased durability and robustness, while a zero tail swing design is ideal for work in confined spaces.

The DX27Z-7M is powered by the DEVELON DN1.7 Stage V compliant diesel engine providing 24.7-hp (18.4kW) of power at 2,400 RPM. As a result, the new mini-excavator offers the highest power and torque in its class and covers a wide range of applications including heavy-duty work.

The DX27Z-7M also offers a high auxiliary flow of 20.3 gpm (76.8 lpm) to enhance work with attachments. Newly designed cast counterweights ensure excellent machine balance and stability when working. A long arm option is available with a 220-lb (100kg) additional counterweight.

The boom swing angle and swing radius are better than or equal to other machines in this class. Visibility and workability are improved by increasing the bucket protrusion distance beyond the tracks. Placing the boom swing cylinder on the left-hand side of cab allows the operator to work right up against walls and other structures on the right-hand side of the machine. The fuel tank and boom swing cylinder have been positioned at the base of the cab, with the Main Control Valve now on the right side of the machine.

New Dozer Blade and Dozer Lever

The DX27Z-7M mini-excavator incorporates a new dozer blade providing both a higher dozer lifting height and dozer digging depth than other machines on the market. Using the new dozer control lever, the operator can select between low and high speed for the levelling blade hydraulics. Travel speed can also be selected by using the travel selector button on the dozer lever. When hydraulic oil pressure rises due to going up a slope while in the high-speed mode, the travel speed auto-shift valve automatically resets the travel speed to low to enhance the operator’s driving convenience and to reduce machine stress.

As well as offering the best performance, versatility, durability and ease of maintenance in the 2t range, the DX27Z-7M mini-excavator features a new larger, roomier cab, providing excellent operator comfort and controllability. The enhanced heating and AC system is the best on the market, providing more nozzles to direct warming and cooling air, including both front and rear pillar nozzles that together help to improve the system performance. Larger nozzles are also used to ensure direct and sufficient airflow for operators and manual adjustment of the opening/closing of the nozzles is also possible.

In the DX27Z-7M mini-excavator, a new EPPR valve is incorporated for two-way and optional rotating functions, that provides the operator with 10-step proportional control of the hydraulic flow rate via the thumbwheel joystick.
