Elevator Traction wheel ThyssenKrupp PMS280 PMS300 PMS320 Elevator Parts

The PMS series of elevator traction wheels, which include the PMS280, PMS300 and PMS320 models, are precision-engineered components designed to meet the demanding requirements of modern elevator systems. Each model has a unique combination of sizes and specifications designed to optimize the performance and durability of specific elevator configurations.

The PMS280 main traction wheel is approximately 335mm in diameter and is equipped with seven 8mm wire rope slots with 110mm wheel thickness. This configuration ensures a smooth and reliable cable engagement, supporting the efficient operation of the elevator under various loads and speeds.

The PMS300 main engine traction wheel is larger at 420mm in diameter and can accommodate 12 slots for 10mm wire ropes. This model further enhances its versatility by combining a set of brake discs, providing enhanced braking performance and safety features.

The series' flagship product, the PMS320, showcases a massive traction wheel with a diameter of approximately 480mm, designed with six slots that were later expanded to accommodate 12mm wire rope slots. Coupled with 130mm wheel thickness, this robust design ensures unrivalled strength and durability, even under the most demanding operating conditions.

A unique feature of the PMS series of traction wheels is its innovative two-part construction. The centre includes a sturdy drum, while the exterior is carefully crafted into a rim-type rope slot, cut precisely into the rim. The outer and inner wheel cylinders are then seamlessly integrated and secured together using hinge bolts, ensuring a strong and reliable connection.

It is worth noting that the diameter of the PMS series of traction wheels is intentionally designed to exceed the industry standard, often reaching 45 to 55 times or more the diameter of the wire rope itself. This extra-large size not only enhances the durability of the wire rope, but also optimizes the contact angle between the wire rope and the groove, reducing wear and maximizing traction efficiency. Overall, the PMS series of traction wheels represent the pinnacle of engineering excellence, ensuring safe, smooth and efficient operation of elevators for years to come.
