DEVELON has launched an upgraded version of its DX35Z-7 four-tonne Stage V-compliant mini-excavator.
The Develon DW01 18.4 kW (25 HP) diesel engine replaces the previous D17 engine in a move the manufacturer said provides better performance for heavy duty applications. The zero tail swing design of the DX35Z-7 makes it suited to work in confined spaces on construction, demolition, landscaping and utility projects.
A further change is the position of the boom swing point, which has been moved 75mm to the right, in combination with a change in the boom swing angle to 60o to both the left and right. This increases the operator’s visual range and visibility from the front of the cab, which has also been boosted by a change in the position of the radio and an increase in the wiper blade angle from 60 to 89o. Boom swing control has also been moved from the pedal to the thumbwheel control on the joystick.
Accessibility has been improved with an increase in the stand tilting angle and by enlarging the width of the cab entrance from 363 to 404mm. Inside the cab, there is 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.
Develon added that the DX35Z-7 now offers more tie down points, making it easier to load and fasten the machine during transportation. The number of lights has also been increased on the outside of the cab.
Other enhancements include increased accessibility to the hydraulic oil filling point, including the addition of a new retractable cover. Battery maintenance has 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 100kg counterweight is designed to ensure ‘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 reduces engine exhaust noise.
