The development of products and services that are economic and preserve the environment is becoming more and more important. Using less energy - be it fuel or electric power - means lower costs for the customer and fewer CO2 emissions at the same time, killing two birds with one stone, so to say. The company STILL has been following such a strategy for a long time already.

Starting points for improvements are on four levels. These are:

- Intelligent solutions to avoid transports by improving intralogistic organisation and processes

- Optimising the fleet and the material flow management systems

- Improving the warehouse trucks and their components

- Involving the driver by respective training.

This is the approach of the new concept "Blue-Q = IQ". It stands for economy and intelligent responsibility for the environment. Optimising the motor characteristics or intelligent switching on of electric components allows to reduce the power consumption to the STILL RX 20 electric trucks by up to 20%.

To propel diesel and LPG trucks, STILL has been using the energy efficient diesel electric drive concept that Hans STILL had first presented in 1953. This drive system has ben continuously developed since then and currently produced the most economic diesel lift truck of its class, the current RX 70. The latest development of the standard RX 70 into a pure hybrid truck with an additional electric energy storage shows that further savings are possible. Energy recuperated when braking is now available to accelerate the truck reducing the consumption up to 11 percent for work cycles with a high share of acceleration and braking, for example, when loading and unloading lorries.

Still has continuously and successfully optimised its fleet to lower operation costs and by this lower CO2 emissions. This way the energy consumption of the electric trucks has reduced by 24 percent since 1990 and the consumption of diesel trucks during the same time even by 32 percent. The use of primary energy by a defined STILL sample fleet has been reduced by 60 compared to 1990. Not only trucks with optimised consumption contributed to this but to a large extend the STILL material flow management systems. A path STILL will closely follow in both directions, for example with the new web based software tool "STILLReport". It allows to optimise the fleet and gives user full transparency of the own fleet or all used warehouse trucks.

STILL shows further potential cost savings for subjects such as remote maintenance and the new tractors, e.g., the new KANVAN making the operation of tractors in route operation even more economic.

Intelligent control of the flow of material and information allows to make use of potential savings. Energy efficiency means economy and ecology at the same time.
