Develon Launches New Upgraded DX35Z-7 Mini Excavator

Develon has launched a new enhanced version of the company’s DX35Z-7 4 tonne Stage V compliant mini excavator.

The Develon DW01 18.4 kW (25 HP) diesel engine replaces the previous D17 engine in the upgraded DX35Z-7, providing better performance for heavy duty applications, with higher power and torque than engines in other machines of this size, giving hours of lower cost, efficient and effective operation. The zero tail swing design of the DX35Z-7 makes it ideal for work in confined spaces on construction, demolition, landscaping and utility projects.

Another change in the DX35Z-7 is in the position of the boom swing point, which has been moved 75 mm to the right, in combination with a change in the boom swing angle to 60° to both the left and right. This increases the operator’s visual range and visibility from the front of the cab which has been further optimised by a change in the position of the radio and an increase in the wiper blade angle from 60° to 89°. Boom swing control has also been moved from the pedal to the thumbwheel control on the joystick.

Enhanced Operator Comfort

Accessibility to the cab has been made easier with an increase in the stand tilting angle and by enlarging the width of the cab entrance from 363 to 404 mm. Inside the cab, the operator is equipped with a new orange seat belt and greater comfort with a reduction of the heat from the seat and improved engine heat dissipation through a change from a sucker type cooling system to a blower type set-up.

The DX35Z-7 now offers more tie down points, making it easier to load and fasten the machine during transportation. For increased safety and ease of operation, the number of lights has also been increased on the outside of the cab.

Easier Maintenance

Other enhancements on the DX35Z-7 include better maintenance through increased accessibility to the hydraulic oil filling point, including the addition of a new retractable cover. Battery maintenance has also been upgraded with the addition of a new battery jump-start feature.

The DX35Z-7 offers a high auxiliary flow of 74 l/min to enhance work with attachments and an additional 100 kg counterweight ensures excellent machine balance and stability when working.

On the intake system, efficiency has been increased by using a two-stage air cleaner filter (inner and outer), with a new clip system that simplifies changing the filters. The excavator also features a new monitoring and alarm system that notifies operators when filter changes are required. A new double-insulator system further enhances operator comfort by reducing engine exhaust noise.

A larger ½-inch arm pipe (up from 3/8 inch) improves arm responsiveness, increasing arm-in speed by 3% and arm-out speed by 15%.

Develon Fleet Management Telematics

By collecting data from sensors on the DX35Z-7, the latest version of the Develon Fleet Management system provides a telematics management system for the machine.
