DEPRAG has developed a drive system made out of stainless steel, consisting of motor, brake assembly and gears.
The drive system has an integrated brake which consists of three brake disks, a pressure spring and a piston.
The brakes are controlled separately using an airline.
When the control line has a pressure of over 5 bar the brake is released, if the pressure drops below 5 bar it is engaged.
The safety valve turns the air feed off if the pressure falls below 5 bar.
The system comes in various torque ranges and speeds.
