Overhead Conveyors

In paint shops, overhead conveyors are primarily used in underbody sealing and seam sealing. Both our electric monorail systems and the Twin Trolley System®, which is available only from Dürr, are ideally suited for this purpose. Suspended roller beds and our newly developed “Friction Drive System” complete our portfolio.


Electric monorail systems (EMS) consist of single trolleys with friction wheel drives, and transport the bodies through the paint shop. The electric monorail system stands for flexibility: Optionally equipped with lifting suspension gear, production lines and transport routes can cross each other and the bodies lowered to any desired working height. Body lift units are used to convey these into other levels.



T.T.S.® is a system in which the idle trolleys are positively driven almost slip and wear free by toothed belts via pusher dogs (trolleys). This allows high speeds to be achieved. Optionally equipped with a flexible lifting suspension gear, the body can be lowered to any working level.

Power & Free

Dürr supplies Power & Free conveyors at the customer’s request. These consist of a continuously running drive chain (Power), which is coupled to the hanger with the help of a latch. By unlocking the latch, the carriage can be stopped as needed despite a running chain (Free).

Suspended Roller Beds

The system with suspended roller beds is based on elements from the skid conveyor system and offers a high degree of standardization and consistency.

Friction Drive System

The “Friction Drive System” transports the body directly on the drive trolley. Stationary drives, which are mounted along a single-track rail system consisting of straight section elements, curves and track switches, push the drive trolleys through the plant. Crossbar conveyor systems are an interesting alternative to conventional conveyor systems. Crossbars are thereby bolted to the underbody of the body and act as product carriers. This way you can do without the otherwise necessary skids. At Dürr, crossbar conveyor systems with standardized elements have proven their worth for years.
