Moving relationship

Many people would not realise that Doosan started life as a small shop in Seoul, Korea, in 1896. The principles of the company are underlined by the meaning of the two words 'Doo' and 'San' which translate simply as 'from tiny grains of sand make a great mountain' and proof of that principal is clearly displayed with their evolution into the Doosan Group we know today. Not many companies can claim such a transformation from the manufacturing of women’s cosmetics in the 1920’s through to forklift trucks in 1968 and nuclear power, turbine manufacture and civil engineering today.

The electric aspect of the Doosan range offers a wide choice of robust capacities from 1.5 to 5t combined with quiet, smooth manoeuvrability and award-winning G2 engine.

At both R&D and production sites in Korea, Doosan utilises Curtis AC control systems that benefit from the powerful enhancements of the E-Series range, like dual-microprocessor I/O logic and software that continually cross-checks critical circuits, ensuring maximum functional safety performance levels that comply fully with EN1175-1:1998+A1:2010 and EN (ISO) 13849-1:2009.

The 1222E controller provides safe 'steer by wire' angle and direction, with the 1236E and 1238E controlling traction and hydraulics to combine powerful performance and reliability with functionality and easy system integration.  

Systems are easily controlled and directed by Curtis’ VCL (Vehicle Control Language) which Doosan has written, with assistance from Curtis. The VCL is able to convert conflicting CAN protocols into one common language for multiple device applications. Curtis VCL application code is said to be at least 10 times faster than similar systems; with more CAN mailboxes and more variables making development faster and more efficient and the end product and user experience smooth and responsive.

Equipment in the field is easily monitored and maintained by engineers using Curtis 1313 intuitive programmers as rapid accurate diagnostic tools for the entire truck system.

Once the forklifts arrive at Doosan’s UK Headquarters, the second part of the Curtis partnership kicks in. Trucks are fitted with additional safety features including the Blue Arrow spot lamp that projects a directional arrow onto floors to alert pedestrians of an approaching vehicle (red also available) and bright, long lasting LED work lamps, as well as a versatile magnetic base engineers work lamps which can be used by either truck operators or maintenance engineers in any environment.

Truck batteries and are matched up with the corresponding Curtis Battery Charger. Varying depending on specification and use, they comprise – mostly – tough stationary Primo Power (or Pulse version for fast charging) - advanced high frequency models or small single phase Piccolos, ideal for wet-cell batteries in pallet trucks.  All Curtis chargers are fitted with REMA connectors and come with long warranty and field support service.  The request and supply system flows totally and easily and it’s fair to say, that trust in the products and services are complete.

Paul Watson, sales director of Doosan is very happy with the multiple benefits of the Curtis connection. “It works in every respect to have this single source of supply and contact. Great products and a strong, easy relationship between the companies in Northampton enable us to provide complete support to our customers, whatever the size of their fleet or location and ensure absolute minimum downtime and impact on their business resources”.
