Develon in double mini-excavator launch

DEVELON has launched two new mini-excavators in the form of the DX17Z-7 zero tail swing and DX19-7 conventional models.

Both machines are powered by the Kubota D902 Stage V-compliant diesel engine, which the manufacturer stated provides a 20% higher gross power output of 12.1 kW (16.2 HP) at 2400 RPM. The engine also offers a 25% larger displacement and 29% increase in engine torque to 54.6 Nm at 1900 RPM.

Featuring the new shared global styling for the next generation Develon mini-excavator range, the platform design and new upper structures in the DX17Z-7 and DX19-7 are said to provide ‘increased durability and robustness’. The compact dimensions make them ‘ideal’ for work in confined spaces.

Both models have a 1.75m boom and 1.03m arm as standard, with an optional longer 1.23m arm available for both. The DX17Z-7 has a cast 180kg counterweight as standard with an additional 85kg counterweight for use with the optional longer arm. The tail swing radius in the DX17Z-7 has been reduced by 6.5% to 645mm compared to the previous model. The tail swing radius increases to 720mm when the additional 85kg counterweight is used. An integral 65kg cast counterweight is used in both the standard and longer arm versions of the DX19-7.

The front assembly in both machines is protected by cylinder guards to avoid collisions or any kind of potential damage, with an optimal hydraulic hose layout which runs through and is protected by the boom structure.

One and two-way proportional flow is provided as standard. Flow is controlled via a thumbwheel on the right hand joystick. With quick coupler piping already available on both models, operators can switch to using a quick coupler by pressing a safety button on the left console – bringing up a warning message on the five inch digital display in the cab to notify the operator, who can then push a button on the right hand joystick to begin quick coupler work.

The DX17Z-7 and DX19-7 are equipped with retractable 230mm tracks, where the width between the tracks can be automatically reduced from 1,290mm to 994mm and both machines have a foldable blade. This allows operators to adapt the width and dimensions of the mini-excavators to navigate through narrow spaces.

The DX17Z-7 is available as a canopy machine, whilst the DX19-7 can be supplied with either a canopy or cab. Both machines share a common set up for the joystick and switch controls.

For enhanced control, a Travel Speed Switch is integrated with the travel control levers, providing quick speed adjustment and ‘improved’ controllability.

The DX19-7 cab is supplied with a heater as standard (with air circulation via three air vents). Working with the door closed, Develon added that no noise or dust enters the cab. A defrost system is designed to ensure clear visibility and a safer working environment. This also prevents temperature-related damage such as moisture build-up.

A mechanical suspension seat is standard for both models, which can be adjusted to take in the differences in body shapes and sizes of operators.

LED lights and a rotating beacon are also standard. The DX17Z-7 has an LED lamp as standard on the boom, whilst the DX19-7 has a light on the boom, with another light on the top of the rear section of the cab in the cabbed version.
