Initially introducing nine new advanced models in the 9-Series covering a capacity range from 3.5-5.5 tonne, Doosan will go on to release further models in the series over the coming months within the capacity range 2.0-3.0 tonne, followed by more in 2021.
The unit offers a 50% larger floor plate, concealed tilt cylinder, increased torso clearance, and an all new ‘full floating’ cabin design with curved front, top and rear glass panels – reducing noise to 79db(A).
At the heart of the 9-Series is the G2 Doosan-built diesel engine, which is specially designed for industrial vehicles. It provides high torque at low RPM – effectively delivering improved forklift acceleration, drive and climb performance. When fitted with a Diesel Particulate Filter (DPF), is compliant with Euro Stage V regulations. In normal operation, regeneration of the DPF takes place automatically during driving – maximising uptime and ensuring uninterrupted all-round performance.
An important cost-saving standard feature of the 9-Series is the multi-torque function, allowing the operator to select the performance most suited to the task. ECO mode minimises fuel consumption, cutting down on unnecessary acceleration; High mode increases power output to match the demands of heavy-duty work; and Standard mode maintains output at levels suited to everyday tasks.
The sensitivity of the inching pedal is adjustable, ensuring accuracy when handling heavy and fragile loads such as glass bottles. In addition, the service brake is designed on the principle of a ‘master brake cylinder’, which increases braking capacity by 200% and reduces braking effort by 20%.
Enhancing overall performance and durability of the rugged 9-Series is the new integrated powertrain cooling system. By streamlining the counterweight profile, improving fan and core clearance, and increasing capacity of the charging pump by 47%, the operating temperature of engine coolant has been significantly reduced from 103 to just 89.2 degrees centigrade.
A fully-adjustable premium Sears & Grammer suspension seat as standard. Other features include a 5” (optional 7”) full colour LCD display presenting operating and maintenance information clearly outdoors, and an easy entry grab-bar and an anti-slip step-plate facilitate safe access to and from the cab. For convenience, a document clipboard and USB port are located within the reach of the operator.
The new 9-Series takes ease of maintenance into account too, with improved accessibility to the engine and service areas – the hood opening has been increased to an angle of 70 degrees and a tool-less side panel and floor plate allow simple access to key areas. The transmission oil filter and pressure check port are placed on top of the transmission for easy inspection and maintenance and electronic components are centralised for convenience.
