DOOSAN has introduced the manufacturer’s new DL-7 wheel loader range.
Powerful by Stage V-compliant engines, seven models are being launched in the first phase: the DL280-7, DL320-7, DL380-7, DL420-7, DL480-7, DL550-7 and DL580-7. A further four models – the DL200-7, DL220-7, DL250-7 and DL420CVT-7 – will be added in 2021.
Charlie Park, CEO of Doosan Infracore Europe, said, “Doosan rolled out its first wheel loaders in 1989. Over the intervening 31 years, Doosan has continuously invested to maintain our position as a leading global brand within the wheel loader industry. Over that time, Doosan engineers have never stopped innovating and developing our wheel loader range.
“Our new DL-7 models are the result of this endeavour and have been redesigned from the ground up. We listened closely to the needs of our European customers and revisited every single aspect of our existing wheel loader product design to provide the solutions they wanted. As a result, Doosan’s new DL-7 wheel loaders will take customer satisfaction to the next level in the industry in terms of market-leading operator comfort, fuel economy, productivity and durability. The innovative technologies we have used in the DL-7 range also clearly differentiate our products from those of our competitors.”
The range marks the culmination of the first complete redesign of the Doosan wheel loader range in 10 years. The new external design has been applied to all models in the DL-7 series, which Doosan said creates a three-dimensional effect with an ‘innovative’ cover shape and a ‘vibrant, dynamic’ image for the range.
Redesigned buckets are said to offer up to 7% more capacity to ensure the new loaders provide faster loading with maximum bucket capacities from 2.8 to 6.4 m3.
The Z-kinematic lift arm is described as delivering high breakout forces and lifting capacities, especially for heavy materials, and a large dump angle for unloading sticky materials. An optional high lift arm is available.
All DL-7 wheel loaders feature a third spool valve with settable flow and detent function, providing a constant flow for hydraulically driven attachments. The machines can be ordered with a choice of different counterweights – options include 300, 400 or 500kg depending on the application.
The new cab offers improved visibility and a 14% larger glass window area compared to the previous DL-5 models. There is the option of electrically adjustable rear view mirrors. Full LED working lights are installed on the cab. An air compressor with air blower is available as an option.
Using the new Doosan Smart Key system on the cab’s control panel, operators can start the machine using a keyless device, helping to prevent machine theft. The cab also features a Grammer Actimo XXL seat with fully adjustable horizontal and vertical suspension settings, a pneumatic lumbar function and seat heating as standard. There is a 3-point safety belt with alarm icons on the new Doosan Smart Touch 8-inch touchscreen monitor and on the gauge panel, which features a new layout and anti-reflective glass.
The EMCV (Electric Main Control Valve) joystick is fully integrated in the armrest. Features available via the EMCV system include Automatic Return-to-Dig, Bucket Tilt Kick-out and the Bucket crowd stop position and shock prevention.
The loaders are powered by new Doosan and Scania Stage V 6-cylinder engines, which meet emission regulations without the need for exhaust gas recirculation (EGR), through the use of selective catalyst reduction, diesel oxidation catalyst and diesel particulate filter (DPF) after-treatment technologies.
