Range of new features on large Doosan loaders

New safety and ergonomic features now available as standard as part of continuous improvement programme

A WIDE range of new features is now available as standard on all five large Doosan wheel loader models – the DL300-5, DL350-5, DL420-5, DL450-5 and DL550-5.

A number of the new features are aimed at increased safety and visibility in and around the operator’s cab. For example, a new handrail has been installed around the cab roof with three holding points, allowing operators to move very safely all around the cab to clean windows and to perform other tasks.

A new large step and access platform has also been added on the front of the cab and a change in the wiring routing has allowed the horn to be repositioned below the road light. Together these changes ensure maximum safety and confidence, with very safe and faster movements around the cab (without any obstacles) during daily maintenance.

Inside the cab there is a new ergonomic joystick control with a progressive thumb wheel added for the auxiliary hydraulic line (third valve). This ensures that no additional lever is needed, providing the easiest combination of movements to manage third-valve operations.

To make life more comfortable and easier for operators, a rolling sunshield has been added to the rear window, the cup holder has been relocated to the front right of the cab and a new double-hanger hook allows both a helmet and a jacket to be hung inside the cab.

The operator has the benefit of additional convex mirrors on the lateral mirror frames. The wider angle and additional visibility provided by the convex mirrors along the side of the machine ensure safer manoeuvring of the wheel loader in the quarry.

A new external, steel toolbox installed below the ladder on the left-hand side of the wheel loader provides a convenient location for storing tools, which are now accessible from ground level, with no need to climb up the side of the cab to reach them.

The wheel loaders feature a new lockable steel cap on the transmission oil filler, the shape of which has been changed to allow it to be locked with a padlock. When the transmission oil filler tube is locked, the transmission oil cannot be polluted with other types of oil or liquid, dust and other substances. It also provides additional security for the customer.

These new features complement the productivity and fuel economy benefits offered by large Doosan wheel loaders, where existing features include: the high-comfort cab; powerful Doosan and Scania Stage IV engines; smooth and responsive hydraulics; a ZF powertrain; and axle cooling and auxiliary hydraulic connections.

Along with the new features on their five largest wheel loaders, Doosan have implemented a restyling of all 12 models in the company’s range, with more dynamic curved lines that are designed to reinforce their robustness and power of Doosan wheel loaders. The new styling scheme also involves a change of colour (from orange to dark grey) for the front lift arm, front frame and front and rear axle components on the machines.
