Among the many components of a three-wheeled vehicle, the manual cookie wire lifter, although seemingly small, plays an indispensable role. It is mainly applied to the window lifting system of three-wheeled vehicles, providing convenience for drivers and passengers.

Structure Composition
The manual cookie wire lifter is mainly composed of parts such as a crank handle, a wire rope, a pulley, a guide rail, and a glass bracket. The crank handle is the starting point of operation and is usually located on the inner side of the vehicle door, making it convenient for the driver or passenger to reach and operate. When the crank handle is turned, the wire rope connected to it starts to move. The wire rope generally uses high-strength steel wire rope, which has good flexibility and wear resistance and can maintain stable performance during long-term use. The pulley is installed at a specific position to change the movement direction of the wire rope, ensuring that the wire rope can smoothly drive the glass bracket to move up and down. The guide rail provides a stable track for the movement of the glass bracket, ensuring the smoothness of the glass during the lifting process and preventing the glass from shaking or jamming. The glass bracket is directly connected to the vehicle window glass, responsible for bearing the weight of the glass and realizing the lifting movement of the glass under the drive of the wire rope.

Working Principle
Its working principle is based on simple mechanical transmission. When the user turns the crank handle, the rotational movement of the crank handle is converted into the linear movement of the wire rope through a series of gears or worm gears. Guided by the pulley, the wire rope pulls the glass bracket in the direction of the guide rail. As the wire rope is retracted and released, the glass bracket drives the vehicle window glass to rise or fall, thus realizing the opening and closing of the window. For example, when the window needs to be closed, turn the crank handle clockwise, and the wire rope is gradually wound around the shaft of the crank handle. The other end of the wire rope pulls the glass bracket to move upward, driving the vehicle window glass to rise until the window is completely closed. Conversely, turn the crank handle counterclockwise, the wire rope is loosened, and the glass bracket moves downward under the action of the gravity of the glass itself, and the window opens accordingly.

Application Advantages
Cost-effectiveness: Compared with the electric lifter, the cost of the manual cookie wire lifter is significantly lower. This makes the manual lifter a preferred choice in the production of some cost-sensitive three-wheeled vehicles. For consumers, when purchasing a three-wheeled vehicle equipped with a manual lifter, the overall price of the vehicle is relatively low, and the later maintenance and replacement costs are also more economical.
High Reliability: The structure of the manual lifter is relatively simple, and the number of components is small, which means that the probability of failure is lower. Without complex electronic components and circuit systems, it also avoids the failure of the lifter caused by electronic faults. In daily use, as long as the wire rope, pulley and other components are regularly lubricated and maintained simply, the manual lifter can work stably and reliably, reducing the inconvenience and maintenance costs caused by the failure of the lifter.
Easy Operation: The manual operation mode enables users not to rely on electricity and not to worry about circuit faults or insufficient battery power. Whether the vehicle is in the starting state or the flameout state, the crank handle can be easily operated to control the lifting of the window. For some people who are not familiar with the operation of electronic devices, such as the elderly, the simple and intuitive operation mode of the manual lifter is more easily accepted and used.

Key Points of Daily Maintenance
Lubrication and Maintenance: Regularly apply an appropriate amount of lubricating grease to parts such as the wire rope, pulley, and guide rail, which can effectively reduce the friction between the components, reduce the degree of wear, and extend the service life of the lifter. At the same time, lubrication can also make the glass lift more smoothly and reduce the occurrence of jamming. It is recommended to conduct a comprehensive lubrication and maintenance of the lifter at regular intervals (such as every quarter).
Check the Wire Rope: Regularly check whether the wire rope has any breakage, wear or rust. As a key transmission component of the lifter, once the wire rope has problems, it may cause the lifter to fail to work properly. If slight wear of the wire rope is found, an anti-rust agent can be applied in time for protection; if the wire rope is severely broken, a new wire rope needs to be replaced in time to ensure the safe use of the lifter.
Clean the Guide Rail: Keep the guide rail clean and avoid dust, debris, etc. from entering the guide rail, which may affect the normal sliding of the glass bracket. A clean rag can be used to wipe the guide rail regularly to remove the accumulated dirt. In addition, it is also necessary to check whether the guide rail is deformed or damaged. If there are problems, the guide rail should be repaired or replaced in time to ensure the smoothness of the glass lifting.

The manual cookie wire lifter for three-wheeled vehicles occupies an important position in the window lifting system of three-wheeled vehicles with its unique structure and simple and reliable working principle. Through reasonable use and correct maintenance, the manual cookie wire lifter can provide long-term and stable services for three-wheeled vehicle users and meet the needs of daily travel.
