<Detail description to components>
1. Belt & Vertical motion pulley
The timing belt of the S8M type delivers the best driving force with high durability and low noise.
The cutting edge power supply of SMPS (Switching Mode Power Supply) method is built in to maintain more efficient power supply, and the microcomputer type of controller ensures more stable running.
Various functions can be set by the user in real time through the LCD (Liquid Crystal Display) window.
It is convenient to install by integrating the input and output terminals. It can be distinguished by the 24V-12V output terminal and check the power-on state through the LED lamp.
It can overcome not only the abrasion of BLUSH which is a disadvantage of general DC motor but also limit of motor trouble and product life cycle.
Moreover, It can be used semi-permanently.
Hypoid gears which produced by domestic technology are equipped to realize smooth running, precision control and powerful driving.
5. Hanger roller
The hanger rollers can control the door horizontally and vertically. It consists of the solid, durable acetyl and advanced noise proof urethane.
The rail is made of 6NO1 material with high hardness and strong against the load, it has the superior structure of component fastening force.
