8×19S+8×7+PP Construction 6 mm Nominal Diameter Elevator Steel Rope with 1570/1770N/mm² Tensile Strength

Product Profile

Custom-built for heavy-load hoisting scenarios, the 8×19S+8×7+PP 1570 elevator steel wire rope adopts an exclusive composite strand layout and delivers outstanding comprehensive mechanical properties.

Internal Structural Layout

Strand Arrangement Parameters

The marking 8×19S corresponds to eight main strands with nineteen individual steel wires per strand, fabricated following Seale strand design. The thickened outer steel wires of this layout greatly strengthen the rope’s ability to withstand long-term frictional wear.

Auxiliary Reinforcement Strands

The code 8×7 stands for eight auxiliary strands, each twisted from seven steel wires. These extra strands jointly boost the whole rope’s tensile load capacity while preserving good bending softness.

Central Core Raw Material

PP is the abbreviation for polypropylene fiber core. This inner core material boasts remarkable pliability, can lock lubricant grease steadily, and effectively withstand radial squeezing deformation.

Core Mechanical Advantages

1. Robust Load Capacity & Wear Durability: Oversized outer steel wires drastically extend service life when rubbing against traction wheels and mechanical fittings.
2. Balanced Softness & Structural Rigidity: The rope retains reliable tensile performance and can freely bend and coil during installation and operation.
3. Efficient Vibration Buffering Function: The polypropylene fiber core works as an internal shock absorber to weaken vibration generated by sudden impact loads during equipment running.
4. Long-lasting Internal Lubrication & Rust Prevention: The fiber core stores abundant grease, cutting internal friction between steel wires and avoiding oxidation corrosion.
5. Stable Chemical Resistance Property: The polypropylene core material endows the entire wire rope with great tolerance to various chemical corrosive substances.

Multi-scene Application Coverage

1. Elevator Traction Systems: Serves as the main load-bearing hoisting cable to guarantee steady, secure daily operation of passenger and freight elevators.
2. Port & Building Site Hoisting Work: Matches universal lifting gear for goods loading, unloading and transfer at docks and construction zones.
3. Mechanical Traction & Power Conduction: Fits winches and assorted lifting machinery that rely on steel ropes for power transmission and pulling tasks.
4. Industrial Lifting Cranes: Applicable to gantry and tower cranes for heavy goods hoisting and traction construction tasks.

Technical Parameter Description

Developed for harsh heavy-duty working conditions that demand high stability, long service life and top safety standards, the 8×19S+8×7+PP 1570 wire rope’s unique composite structure delivers stable and outstanding performance amid complicated industrial operating environments.
