The present disclosure illustrates a sectional door driving device including a power assembly, a chassis assembly and a driving assembly. The power assembly includes a motor, a gear set and a control unit, and the power assembly is fastened on a main chassis of the chassis assembly. The driving assembly includes two half-gears respectively in semicircular cylinder shape, and each of the two half-gears has a combination surface which is formed with an engagement assembly, and the two half-gears are engaged by the engagement assemblies thereof to form a circular gear to cover a shaft of a sectional door mechanism. The gear set includes an output gear configured to drive the circular gear and the shaft to rotate. The sectional door driving device can be separated from the shaft easily for repair, and the sectional door driving device can also be installed on the existing sectional door easily.

The invention relates to a door system (1) comprising a door (2) and two lateral guide elements (4, 5), wherein the door (2) comprises multiple slat elements (6) which are connected to one another and can be detached from one another, and which are arranged orthogonal to the guide elements (4, 5) and can be guided in the guide elements (4, 5), and a drive device (8) is provided for opening and/or closing the door(2), wherein the door (2) can be lowered and/or raised for opening and/or closing and can be lowered into a box (9) for opening, and the individual slat elements (6) are arranged next to one another inside the box (9) in an open state of the door (2). The drive device (8) is a cable pulley system (10) which can be driven by a horizontal drive spindle (11) and wherein a cable (12) of this pulley system (10) is connected to at least one slat element (6) in the vertical direction (V).

A non-module type dual regulator assembly includes a pair of guide rails that are separated from each other and disposed in a door of a vehicle along a direction that a window glass is raised or lowered. A pair of glass holders are coupled to one side of the window glass and movably disposed on the respective guide rails. An upper connection member has a plurality of ends fastened to upper portions of the guide rails. A lower connection member has a plurality of ends fastened to lower portions of the guide rails. A cable is coupled to the glass holders and circulatably disposed along the guide rails to raise or lower the glass holders in the same direction at the same time. A driving motor is disposed on the lower connection member and circulates the cable.

The present invention is generally a movable barrier assembly that includes a screen garage door that may be remotely operated to open and close an entry to a garage, thereby facilitating ventilation, and preventing debris such as leaves, insects, etc. from entering the garage. In an exemplary embodiment, a screen assembly includes a first track running substantially parallel to a second track on which a garage door travels. A movable barrier operator that actuates the garage door and screen door may include a first motor to operate the screen door, and a second motor to operate the garage door. In exemplary embodiments, a single control unit is configured to operate both motors and thus operate each movable barrier.

The overhead door lift assembly integrates a traditional torsion spring and an electrically powered operator into a small package mountable in the available head space of conventional tractor trailers, cargo vehicles or other structures. The lift assembly includes a torsion spring counterbalance, electrical operator, and back tension mechanism. The electrical operator uses an electromagnetic clutch and gearbox that couples directly to the cable drums of the counterbalance. The electromagnetic clutch allows the overhead door to be manually raised and lowered in the event of a power interruption or operator malfunction. The back tension mechanism prevents cables from inadvertently unspooling from cable drums as the operator starts to move the overhead door from its horizontal open position to its vertical closed position.
