Type of gate operation modes: a parallel shift along the building wall. Movement in the form of points single fan unidirectional fan unidirectional, a fan bidirectional parallel shift, pan and steering sway. Bearer:

(1) Suspension (load-bearing), lower guide; way bearing on the characteristics: high strength carrier rails of the upper part of the door, carrying performance, high reliability and dynamic friction is small, turned on the light, smooth, open the door to start small torque, running noise low power consumption; flexible door bottom guide system installation, convenient and simple to adjust; door installation space is small, compact, easy to install; easy maintenance and low cost.

② support (load-bearing), the guide way. The door bearing from the bottom of the track, the top guide; According to the structural characteristics of the building, to the top of the door leaf number and storage space and Methods; durability, minimal maintenance, security and control is simple; adapt to a variety of insulation and the outer layer of the system.
