The safety rope of the suspended platform
is a key equipment to protect the life safety of workers in construction and
high-altitude operations, and is known as the "lifeline". Choosing a
suitable safety rope can not only effectively reduce the risk of operation, but
also improve work efficiency.
1. Material selection
The material of the safety rope directly
affects its strength, durability and safety. Common safety rope materials
include high-strength steel wire rope and synthetic fiber rope (such as nylon,
polyester, etc.).
Wire rope: Steel wire rope has the
characteristics of high strength, wear resistance and corrosion resistance, can
withstand large tension, and is suitable for long-term use. It has high tensile
strength and can maintain good performance even in harsh environments.
Synthetic fiber rope: Synthetic fiber rope
(such as nylon, polyester) is relatively light, elastic and easy to operate,
but its durability and wear resistance are slightly inferior to steel wire
rope.
When choosing materials, it is recommended
to give priority to high-strength steel wire rope, especially under conditions
with large loads or harsh environments.
2. Specifications
The specifications of the safety rope
include diameter, length and number of strands per strand, which directly
affect its load-bearing capacity and use effect.
Diameter: The diameter of the safety rope
should be selected according to the load and lifting height of the suspended
platform. Generally speaking, the diameter should not be less than 6mm. For
high-strength steel wire rope, the diameter between 8mm and 12mm is more
common.
Length: The length of the safety rope
should be determined according to the operating height and operating range of
the suspended platform to ensure that the operator is always in a safe state
during use. The recommended length is generally between 15-20 meters.
Number of strands per share: The more
strands per share, the higher the tensile strength of the rope and the better
the safety.
3. Safety factor
The safety factor of the safety rope refers
to the ratio of its breaking tension to the maximum working load. According to
Chinese standards, the safety factor of the safety rope should not be less than
9. This means that the breaking tension of the safety rope is at least 9 times
its maximum working load, ensuring that there is enough safety margin in case
of emergencies.
4. Inspection and maintenance
When choosing a safety rope, you also need
to consider the convenience of its inspection and maintenance. The safety rope
should be inspected regularly and replaced in time when problems such as wear,
broken strands, and rust are found. It is recommended to conduct a
comprehensive inspection of the safety rope at least once a month.
5. Brand and certification
Choosing a well-known brand of suspended
platform can better guarantee the quality of the safety rope. Some well-known
suspended platform brands, such as Shenxi Machinery, have a strict quality
control system, and the quality of the safety rope produced is more guaranteed.
In addition, qualified safety ropes should
have national or international certification marks, such as CE certification,
GB standards, etc., to ensure that they meet safety standards.
6. Usage specifications
When using safety ropes, you should also
pay attention to the following points:
Fixed method: The safety rope should be
fixed in a reliable position on the building and should not be connected to any
part of the suspended platform.
Firm connection: The connection between the
safety rope and the suspended platform, hook, etc. should use a special
connector to ensure a firm and reliable connection.
Avoid knotting: The safety rope is not
allowed to be knotted and extended.
