Technical data of the maintenance-free push-pull chain system

The compact rigid system allows the precise and jerk-free lifting of loads of up to 2.0 tonnes within 10 seconds to a height of 2 metres. The space-saving dimensions of the Marathon Lift, which enable the system to be integrated even in confined spaces, are also compelling.
