Exactly the Varistart concept for turning machines. A starting phase with a high torque, a progressiv acceleration and a smooth transition to direct drive.

Varistart for carriage is a pure demonstration of the Varistart concept.

At each moment, the cariage can be slowed down or stopped using conventional methods. It can work in both direction or for starts in turns. When particulary heavy weight is carried, the Varistart equiped carriage offers the possibility to operate few starting phases in order to reduce the effort or when an assistance is needed for climbing slopes for example.

Learning and ergonomy are optimised as the carriage commands are exactly the same than a conventional one, without any other action but a potential lock of the Varistart assistance.
