Sliding Gates

844 MC Gearmotor

The 844 gearmotor was designed to move the heaviest commercial or industrial gates in the simplest, most convenient way.

The special twin-disk anti-crushing clutch, in oil bath, enables thrust adjustment from 0 to 110 daN. As the gearmotor is non reversing, no electric locks need be installed and, in the event of power failure, the key-operated release device makes it possible to open and close the gate manually. LONG LIFE Constant, complete oil-bath lubrication of mechanical components plus assembly in a high resistance pressure-cast aluminium body ensure a very long life.

All commands come from a control board with microprocessor, on the leading-edge in terms of safety and reliability. Leaf stopping space can be electronically programmed.

The electronic equipment housed inside the gearmotor facilitates and speeds up installation, at lower cost.
