Gear with drum

An alternative for cramped manhole conditions


In case of tight spaces when no counterweight can be accommodated with the drive drum provides a solution.
The drives of the TW series with different drum diameters for a total load (F + Q) up to 2000 kg and max. 0.63 m / s (EN81-20) are used here. A drum drive is also a solution in the new installation and as a replacement of hydraulic systems.
For the implementation of UCM, the NBS safety device can be used according to EN 81-20/-50.
