It is the only truck of its kind in the world — and since 22 June 2012, a prototype Linde E25 L Roadster from Linde Material Handling (MH) has been in operation at Fraport Cargo Services GmbH at Frankfurt Airport. The truck is being used to assemble air freight pallets and is being subjected to extended periods of testing. For Fraport, this truck increases flexibility. To ensure safety when loading air freight pallets, forklift truck drivers often have to work with a second person, whose role is to provide the driver with instructions — but when using the Linde Roadster, an innovative clear-view electric counterbalance truck, this form of assistance is no longer required.

The Roadster version was made possible thanks to the tilt cylinders mounted on the top of the lift mast — a selling point unique to all Linde counterbalance trucks with a lifting capacity of up to 8 tonnes. The tilt cylinders redirect the forces on the lift mast into solid cast supports at the rear of the truck. The protective roof consists of two panes of special, laminated safety glass, which mirror the back and forth movements of the mast. The new overhead guard replaces the A and B pillars, as well as the roof column and roofing sheets, opening up the roof of the truck to provide an unobstructed upwards view for the driver, without roofing sheets in the way. The glass roof fitted to the lift mast also provides protection against loads that could fall through between the mast and the driver's seat.

The new design of the prototype Linde E25 L Roadster, which features an overhead guard made from laminated safety glass, significantly improves the driver's field of vision, both in front of and above the truck.

The removal of the A pillar significantly increases the driver's field of vision in front of the truck, too. The step is just as easy to see as it is in a series production truck, and the driver is provided with a curved steel tube, joined to the front plate, as an aid when getting into the truck. The inspiration for this helpful feature came from stair banisters.
