DEVELON - the new name for Doosan Construction Equipment - has launched the new DX62R-7 and DX63-7 six tonne Stage V mini-excavators
The DX62R-7 and DX63-7 are ideal for projects in construction, landscaping, utilities, rental, agriculture, recycling, waste and many other areas. Both models are powered by the new D24 Stage V diesel engine providing 44.3 kW of power. Despite offering an 8% increased torque of 26.5 kgm/rpm, the D24 engine still provides a 7% decrease in engine fuel consumption.
The DX62R-7 and DX63-7 utilise a 'Load Sensing System' based around a new main control valve resulting in a longer spool stroke for improved controllability and superior working efficiency/performance compared to previous models. Both machines offer an auxiliary flow of 90l/min to enhance work with attachments. The flow capacity can be monitored on the Smart 8 inch touch screen in ten steps and controlled using the thumbwheel on the joystick.
The new cab on the DX62R-7 and DX63-7 is very roomy for this size of machine, and features a full glass entry door. A rear-view camera is optional and the high luminance LED work lamps further enhance visibility and safety.
Other features of the new cab include an HVAC system, DAB radio (handsfree & Bluetooth), sunglasses case, a heated air suspension seat, USB charger & 12V Socket and foldable pedals.
Using the dozer 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 driving 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.
Dozer control also provides a new blade floating function - pushing the lever forward puts the lever into the detent position and leaves the dozer blade in a ‘float’ position. Customers can also choose the optional Dozer lock function, which prevents dozer blade creep. If the machine has the optional blade lock valve installed, the floating function will not work when the lever is in the detent position.
The DX62R-7 and DX63-7 feature a new two-part bonnet cover, with fully opening centre and side segments giving easy access for maintenance work compared to the previous generation machines. The mini-excavators also have the Develon Fleet Management TMS 3.0 Cellular system installed as standard, which provides a telematics management system by collecting data from sensors on the machines.
