Primarily composed of upper machine, Chinese machine, lower hand-cranked machine, chains, steel wire ropes, and switch gears, etc.

Working Principle

★ The hand-cranked machine under this product is an active mechanism, while the Chinese-style window opening machine and the top-opening window machine are transmission reduction mechanisms.

★ Linked together with interlocking steel pipes, the Chinese-style and top-opening window machines drive the moving chains, steel cables, and switch gears to connect with the window sashes. Primarily used for opening and closing high windows or sliding window sashes.

★ When operating the hand-cranked opening window mechanism, power is transmitted to the Chinese-style opening window and top-style opening window, allowing the window sashes to slide or slide open and close.

★ A gauge is attached to the output screw of the hand-cranked window opener, indicating the distance for opening and closing the window sash.

★ This window opener can open and close multiple windows, thereby reducing the construction and maintenance costs.
