            In the case of direct drive, the motor has a built-in over-torque protection device, which is triggered by a device built into the gearbox when the door is overloaded by the weight of the door or when the door operation is blocked for other reasons.<\/p>\n\n\n\n

                 When the chain is driven, by installing a fall prevention device at the other end of the shaft (similar to the function of a car seat belt), when the door body falls down and the speed of the door shaft exceeds the limit<\/p>\n\n\n\n
