Wire Rope for Elevators, Hoists and Construction Sites

Explore steel wire ropes for elevators, construction hoists, and building sites across Cameroon, and discover how CML SARL in Douala delivers safety and certified performance.

Urban centers across Cameroon—notably Douala, Yaoundé, Kribi, and Limbe—are experiencing sustained growth in commercial real estate, hotels, high-rise office towers, and industrial infrastructure. This construction boom relies on two vital wire rope sectors: temporary construction equipment (tower cranes, builders' hoists, passenger/material elevators) and permanent vertical transportation systems (commercial passenger and traction goods elevators). At CML SARL (Cameroon Maritime Logistics), we provide specialized steel wire ropes engineered to satisfy the rigorous safety requirements of construction sites and elevator systems. This article details the structural characteristics, standards, and maintenance criteria governing elevator and hoist wire ropes in Cameroon. ### Traction Elevator Wire Ropes: Specialized Engineering Elevator ropes are not standard hoisting cables. In a traction elevator, the car and counterweight are suspended by multiple parallel ropes driven by friction across the grooved traction sheave of the elevator machine. - **International Standards**: Traction elevator ropes comply with **ISO 4344** and **EN 81-50 / EN 12385-5**. - **Dual Tensile Construction**: High-speed passenger elevators frequently use dual-tensile ropes (e.g., grade 1180/1770 N/mm² or 1370/1770 N/mm²). The outer wires are drawn to a lower tensile strength (around 1180–1370 N/mm²) to be softer and more ductile, reducing wear on traction sheave grooves, while the inner wires possess ...
