I. What are the common type of wire rope used in suspended platform
From a practical application perspective, wire ropes used in construction suspended work platforms are mainly divided into two categories:
1. Working Wire Rope (Lifting Wire Rope)
The working wire rope is the main load-bearing wire rope of the suspended platform, directly bearing the weight of the platform, personnel, and construction load.
Main features:
Directly in contact with the friction wheel of the hoist
Strong load-bearing capacity and high wear resistance
Each suspended platform is usually equipped with 2 ropes
Common specifications:
Φ8.3 mm (most commonly used for ZLP630 and ZLP800 models)
Φ9.1 mm (used for heavy-duty or reinforced configurations)
2. Safety Wire Rope (Anti-fall Wire Rope)
The safety wire rope is used for fall protection and works in conjunction with the safety lock. It provides emergency braking in case of abnormal operation of the working wire rope.
Main features:
Does not participate in normal lifting
Independently suspended, and must not be mixed with the working wire rope
Each suspended platform is usually equipped with 2 ropes
Common specifications:
Φ8.3 mm (same specifications as the working wire rope, for easy interchangeability)
II. Classification by Wire Rope Structure
Wire ropes used in temporary suspended platform have specific structural requirements. Common structures include:
6×19 wire rope
High strength, good wear resistance, suitable for suspended scaffolding lifting systems
6×31WS wire rope
Better flexibility, longer service life, often used in high-end suspended platform cradle
⚠️ It is not recommended to use overly flexible structures (such as 6×37) on suspended platforms, otherwise it is prone to slipping, affecting the service life of the hoist.
III. Classification by Surface Treatment Method
Galvanized Steel Wire Rope (Mainstream Choice)
Good corrosion resistance
Suitable for outdoor, high-altitude, and long-term construction
Widely used in export suspended platforms and overseas engineering projects
Plain Steel Wire Rope
Lower cost
Prone to corrosion
Only suitable for short-term or indoor use
IV. Common Steel Wire Rope Configurations for Different Suspended Platform Models
| Model | Working Steel Wire Rope | Safety Steel Wire Rope |
| ZLP500 | Φ8.3 mm | Φ8.3 mm |
| ZLP630 | Φ8.3 mm | Φ8.3 mm |
| ZLP800 | Φ8.3 / Φ9.1 mm | Φ8.3 mm |
V. Specifications for the Use and Replacement of Suspended working Platform Wire Ropes
According to construction safety regulations and industry experience, the following points should be noted when using suspended platform wire ropes:
Working wire ropes and safety wire ropes must not be mixed.
Wire ropes with broken strands, flattening, or severe corrosion must be replaced immediately.
It is recommended to replace the entire set when replacing.
The safety lock must match the wire rope diameter (e.g., Φ8.3 mm).
VI. Conclusion
In summary, suspended platform wire ropes are mainly divided into two types: working wire rope and safety wire rope.
Both have their respective functions and are indispensable. Choosing the correct specifications, structure, and surface treatment method can not only improve construction safety but also effectively extend the service life of the entire swing stage.
If you are purchasing wire ropes for ZLP630/ZLP800 construction gondola lift, it is recommended to prioritize high-strength galvanized steel wire ropes and ensure their complete compatibility with the hoist and safety lock.
