<p>#CMT# #/CMT# The device has a gate movement element i.e. gate shaft (2), for opening and closing a gate, and a fastener arranged on the gate movement element. A gate drive (1) includes two electric motors (3, 4), where one of the electric motors (3) is indirectly/directly connected with the fastener. The other electric motor (4) is radially and movably arranged at the gate movement element, and is connected with the gate movement element by the fastener. The electric motors are drive motors or direct current motors. #CMT#USE : #/CMT# Device for driving a gate e.g. rolling shutter gate and sectional gate (all claimed), in a garage, garden, hall and large industry. Can also be used for a swing gate and sliding gate. #CMT#ADVANTAGE : #/CMT# The electric motor is indirectly/directly connected with the fastener that is arranged on the gate movement element, and another electric motor is radially and movably arranged at the gate movement element and connected with the gate movement element by the fastener, thus driving the gate in an inexpensive manner, and achieving self-improvement of the gate drive in a simple manner. The device utilizes two smaller, standard, inexpensive electric motors to reduce the manufacturing cost of the device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a connection diagram of a gate drive. 1 : Gate drive 2 : Gate shaft 3, 4 : Electric motors 5, 6 : Input pinion gears 7 : Transformer.</p> |
