Classification of steel rope

The steel rope is divided into two types hemp core and steel core.  according to the rope core. 
(1) The hemp core is divided into two types: natural fiber core (NF) and synthetic fiber core (SF).
The fiber core has the following characteristics: the fiber core wire rope is soft and has good bending performance. The fiber core acts as a buffer when the steel rope is subjected to impact and impact loads during operation. Natural fiber cores store a lot of oil. When the steel rope is working, it has sufficient lubrication inside and can slow the corrosion of the steel wire. Synthetic fiber cores (such as: polypropylene, polyethylene) have strong toughness, no water absorption, acid resistance, alkali resistance, corrosion resistance, and extrusion resistance. The steel rope is not easily deformed during dynamic load use, and the diameter is uniform and stable.
(2) The steel core is divided into two types: independent metal core (IWRC), parallel tantalum core (CFRC) and independent metal core (IWSC).
The metal cord steel rope has the following characteristics: the metal core steel rope has large breaking force, resistance to extrusion and high temperature resistance.

Brief analysis of escalator handrail

Price difference of escalator handrail belts: Handrail belts are usually composed of styrene-butadiene rubber (SBR) and natural rubber. The formula of the handrail strap itself is different, which directly affects the stability and life of the escalator handrail. Shaanxi Sanjin Elevator Fittings Co., Ltd. has been cooperating directly with the manufacturer of brand escalator handrail supply many years,could offer different kinds of handrails,such as Mistubishi,KONE,Schindler,Thyssen,fujtec,OTIS escalator handrail . The formulation of the factory is stable, the material is high quality, and the product can be used for 3-5 years without any problems. Therefore, the cost is relatively high, but the price is reasonable because of the large sales quantity. Nowadays,In order to compete with others, some small factories may use reclaimed rubber, which is rechargeable and has a life of only 1-2 years. Therefore, the price is lower. When choosing the supplier of eacalator handrail, please consider the cost-performance ratio comprehensively, and it is better don't only focus on the price.

In addition, when the handrail is installed, it should not be too tight, will cause fever situation,also will affect the life of the handrail.
