Elevator landing Door wire rope wheel Mitsubishi 90MM Elevator Parts

Product Information 

Size Specifications: Common dimensions include a diameter of 90mm, a thickness of 11mm, and a length of 6200mm. For example, there is a wire rope wheel with the model number 90116200. 

Materials: Generally, there are pulleys made of metal wheel bodies combined with nylon wear-resistant materials. There are also materials like iron sheet wheels and nylon wheels. Some wheels come with brackets. 

Brand and Models: The brand is Mitsubishi. Specific models vary according to different application scenarios and elevator models, such as the 66 iron sheet wheel with a bracket (with a hole spacing of 80mm) and the 66 iron sheet wheel with a bracket (with a hole spacing of 70mm). 

Product Functions

Support and Guidance Function: Installed on the landing door hanging plates of Mitsubishi elevators, it bears part of the weight of the landing doors. Through cooperation with the wire ropes, it provides a stable supporting force for the landing doors, ensuring that the landing doors always remain in a horizontal and vertical state during the operation process and can open and close smoothly along the predetermined tracks, thus guaranteeing the safety and comfort of passengers when entering and exiting. 

Transmission Function: As a key component of the landing door transmission mechanism, when the car door drives the landing door to move, the wire rope wheel rotates to drive the wire ropes to move, thereby realizing the interconnection between the landing doors and enabling the two landing doors to move synchronously in opposite directions, ensuring the normal opening and closing actions of the landing doors and improving the operating efficiency of the elevator. Reducing Friction and Wear Function: The design of the cooperation between the groove of the wheel and the wire ropes can effectively reduce the friction coefficient between them, decrease the wear of the wire ropes and pulleys, extend their service lives, reduce the operating noise, and also help to reduce the energy consumption during the operation of the elevator, improving the overall performance and economy of the elevator. 

Tension Adjustment Function: In some landing door structures, the position or tension of the wire rope wheel can be adjusted by means of adjusting bolts and other methods to ensure that the wire ropes always maintain an appropriate tension degree. This prevents problems such as wire rope breakage caused by excessive tension or a reduction in the service life of the wire ropes, as well as slipping and poor transmission caused by insufficient tension, ensuring the reliability and stability of the landing door transmission system.
