Definitions

• the invention relates to a device for holding a drive means, winch or motor, of roulette wheel in a winding box closed at each end by a cheek, the winch or the engine being disposed inside the trunk in the vicinity of a first cheek, and a hoisting tube of an apron extending between the winch or engine and the other cheek, the first cheek having in its central part a clean support pin to be engaged in a housing of the winch housing or engine facing.
• the winch For projects in which the rolling stock has been prepared in the workshop and is delivered in a closed box containing the winch, the winch must be immobilized in rotation in order to prevent the winding tube to turn freely in the boot in the absence of a drive rod connected to a crank handle of the winch and, on the other hand, to cash the resistant maneuvering torque during the raising and lowering of the apron when the moving car is in place. Otherwise the stop effort in rotation of the winch is only taken up by the drive rod which generates excessive forces in the bearings of a winch input pinion, thus risking to damage the life of this winch.
• roller shutter When the roller shutter is driven by an electric motor, instead of a winch, it is advisable to ensure easy mounting of the engine on the adjacent cheek, with sufficient maintenance of the motor housing to prevent its rotation. It may also be necessary to slightly turn the motor head on the cheek, to change the orientation of the limit switches to give them easier access during the final adjustment phase on site. Indeed if the shutter is placed in inner or outer winding, we can change the orientation at the time of installation, in order to have a more convenient access.
