Overhead Conveyors

Electric Monorail System (EMS)

Electric monorail systems from Dürr are available as standardized systems and as a special solution:

  • Lightweight EMS for the transport of smaller components up to 500 kg, such as doors, cockpits, engines and other assemblies
  • Heavy-duty EMS suitable for transporting bodies with its payload capacity of up to 3,000 kg. Special designs up to 7 tons have already been realized.

Dürr supplies and develops hangers with stroke scissors with a stroke of up to 4.5 m in a variety of different designs, each individually adapted to the needs of our customers. This allows optimum ergonomic conditions to be created for every work cycle and the transfer of logistics and transport routes inside the factory.



Lifting Suspension Gear

Height-adjustable load-bearing devices (lifting suspension gear) from Dürr can be used in combination with electric monorail systems or the Twin Trolley System(T.T.S.®). The scissor lift ensures hanger stability and allows individual height adjustment at every work zone. Body carriers are available as C-, T- or four-arm hangers. The lifting function is carried out via a polyurethane belt with integrated steel cables and is designed for a payload of up to 3 tons.

Optionally, the conventional use of busbars can be replaced by non-contact energy and data transmission. This leads to less wear, higher availability and, ultimately, minimized repair and maintenance costs. A swivel arm system enables the transfer from overhead to floor conveyors. The system can also be equipped with a body locking device.

Thanks to their minimum height requirements, Dürr lifting suspension gear can be used in almost all existing plants in the body shop, painting and final assembly areas. These permit complete accessibility to the body and can be used in flow or stop-and-go modes. The standardized, modular system meets all worldwide safety standards in the automotive industry.

Twin Trolley System (T.T.S.®)

The conveyor system developed by Dürr can be used either as an overhead or floor conveyor system. In contrast to the electric monorail system, the drives are not housed on the carriage, but on the track. The two pusher dogs (trolleys) of a carriage are positively driven by toothed belts. This allows very high speeds to be achieved. Horizontal and vertical bends as well as track switches, turning elements and cross transfers stand for high flexibility.
