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.
