The window-opener primarily by the major part of the drive motor, worm gear reducer, chain, wire rope, pulleys and other components and switches, Power-driven machine output power pulley, worm gear, then its output shaft sprocket rope chain drive for reciprocating linear motion, thereby pulling the switch is open and close the sash by limit switches control opening and closing of the sash in place. The model Power-driven window-opener no Manual device for power outages, failure to use. In operation purports sash stops at any position, as long as you can tap the stop button.

Transmission principle and structure
1, Power-driven window-opener with a three-phase AC 380V, 750W Power-driven drive, v-belt, worm gear reducer, driven by the output shaft sprocket chain, wire rope for reciprocating linear motion in the axial direction, the rope through a pulley, with wire rope turnbuckle rigging taut, when the cable is reciprocated in a linear direction by rod, rod drive bracket open and close the sash. Since the rope is Flexible structure, convenient and flexible disposed within the range set by the length of the sash, to meet a variety of building structures in the form of design requirements.
2, in order to facilitate opening and closing of the sash Manual requirements when installing and commissioning power in Power-driven window-opener end shaft equipped Hand-cranking handle backup.
3, window-opener and stopped by the operation of the electrical control box. Equipped with the power switch on the control box panel, indicators, and push-button control. Turn on the power switch, indicator light, it can be Power-driven hoist. To turn sash, press the button to open, Power-driven machine forward window-opener will open the sash, window sash at full stroke switch is broke, Power-driven machine is stopped. To close the sash, pressing the button closed, Power-driven reverses, window-opener shutting the sash is closed the window was forced open limit switch, Power-driven machine stops running. Such as sash switch must stop at an intermediate position, stop pressing the button operation can stop in the middle of the set position. The operation is completed to cut off the power switch.
