The two Expert-T controllers used here, which are also from Movecat, were developed for the systemic control of kinetic drives in complex projects where up to 240 fixed- or variable-speed drives may be in use simultaneously. The selected combination makes it possible to realise intelligent and safe, variable-speed hoisting systems of the highest technical quality complying with BGV C1 and SIL 3.
The VMK hoists from Movecat are notable for their features, flexible handling and conformity with high safety standards. A thermo-sensor, for example, is constantly monitoring the operating temperature of the motor, and no friction clutch is required by VMK hoists as an overload protection, so closed linkage and positive locking between the motor and load are guaranteed at all times.
For the VMK-S hoists, a high-resolution incremental encoder ensures positioning accurate to the nearest +/- 1 mm or better and therefore precise target runs with maximum repetitional accuracy. A dynamic load measurement system is integrated to protect against both excessive and insufficient loads.
