With the help of planetary gears it is possible to implement dual drive systems or emergency drive systems in critical plant components such as oxygen lance winches and lifts. Two different output shaft speeds can be generated, purely mechanically, so as a result there is often no need for expensive frequency-controlled motors. A second drive is coupled in or decoupled via the planetary gear stage. At the same time the redundant drive provides a very high level of operating reliability.
The design is either as a vertical standing foot-mounted or 3-point gearbox. A series developed specifically for this purpose meets the special operating requirements such as frequent acceleration and slowing down, plus reversing. The toothing is optimised to the static strength which is crucial for wheel slip. This results in smaller and, at the same time, more reliable gears for our customers for this application.
The horizontal and vertical drives of wire and profile lines are subject to a number of highly specific requirements. The ambient conditions, for example, are more than harsh. This ranges from the cooling water that flows over the gear to the extreme amounts of dust and scale that occur. These conditions have been accounted for down to the very last detail in an Eisenbeiss gear programme developed especially for this purpose.
