What Characteristics Should A Good Traction Elevator Steel Belt Have?

As the core load-bearing component of modern traction elevators, the quality of traction steel belts directly determines the safety, stability, and economic efficiency of elevator operation. Unlike traditional traction steel wire ropes, high-quality traction steel belts provide better performance support for elevator operation with their special structural design. So what kind of traction steel belt is a qualified and high-quality product?

Firstly, high strength and excellent fatigue resistance are the core requirements for high-quality traction steel belts. A good traction steel belt is equipped with multiple high-strength galvanized steel wire ropes arranged at equidistant intervals. The single wire structure is dense, and the overall breaking load meets the national standard requirements. It can withstand the repeated pulling of the car and load for a long time. At the same time, the tight combination of polyurethane coating and internal steel wire rope gives the steel belt excellent bending fatigue life, which can withstand millions of repeated bending deformations without premature internal rope strand breakage, structural looseness and other problems. The design service life should reach more than 15 years to meet the long-term operation needs of elevators.

Secondly, appropriate friction characteristics and structural design are the guarantee for safe operation. The high-quality traction steel belt adopts a flat structure design and is wrapped with high friction coefficient polyurethane material on the outside. Compared with traditional steel wire ropes, the contact area with the traction wheel is increased several times, and sufficient friction can avoid the risk of slipping and rolling when the elevator is overloaded and descending. Even in a braking test with 125% rated load, it can maintain stable traction force. At the same time, the highly flexible structural design allows for the adaptation of smaller diameter traction wheels, effectively reducing the volume of the traction host, lowering the requirements for shaft space, pit and top floor height, and adapting to the design needs of modern building small machine rooms and even elevators without pits.

Thirdly, stable weather resistance and low maintenance are key for long-term use. The external coating of high-quality traction steel belt has excellent anti-aging performance. It will not have surface cracks, embrittlement, dents, bulges and other problems after three or five years of use. It can resist environmental temperature and humidity changes, oil dust erosion, and has good adaptability to various use environments. At the same time, the fully wrapped structure protects the internal steel wire rope from rust and wear, and there is no need to apply additional lubricating oil for maintenance during use. Only regular cleaning of surface dust is required, which not only reduces maintenance costs but also avoids lubricating oil dripping and polluting the wellbore environment, reducing friction noise.

Finally, strict compliance with national standards and regulations is the bottom line requirement. The production and manufacturing of high-quality traction steel belt must comply with national standards such as GB/T 39172-2020 "Non steel Wire Rope Suspension Devices for Elevators", and all performance parameters must meet the requirements of GB7588-2020 elevator safety regulations. The entire process from production to installation and replacement must follow industry standards, eliminate unqualified raw materials and cutting corners, and ensure the safety of elevator operation from the source.

In summary, a high-quality traction steel belt is the unity of strength, friction performance, weather resistance, and compliance. It silently carries the safety of every vertical travel and is the cornerstone of reliable elevator operation.

Uliflex Industrial Belt insists on using high-quality raw materials for elevator traction steel belts, putting the safety of elevator users' lives first. Despite the increasingly fierce competition in the elevator steel belt market, Uliflex Industrial Belt still adheres to the safety bottom line, firmly opposes the use of cheap and average performance raw materials, and firmly opposes concessions in raw material selection to reduce costs.

Uliflex's elevator traction steel belts have been tested by third-party testing agencies, ensuring the safety of elevator users is Uliflex Industrial Belt's operating bottom line. We believe that the quality of a product is directly proportional to its price. Low priced products are almost equivalent to average product quality. Products made from high-quality materials will definitely not be lower than market prices. You get what you pay for.
