,The safe use of lifting equipment has a very important role in terms of occupational health and safety. Ropes preferred for lifting heavy loads should not create danger in working processes. The safety coefficient in ropes means the ratio of the strength value used in the design of the mechanism to the maximum durability of the material. It responds to the needs of users by being produced according to different lengths, metres and safety ratios.
What are the Safe Working Conditions of Ropes?
Accessories used in lifting operations complete the process when they work safely. Appropriate choices are made so that occupational safety is not jeopardised. According to the regulation, the safety coefficient requirements for ropes are as follows:
- The working coefficient of wire rope and rope end combinations is equal to 5.
- Ropes do not have any attachments other than the end.
- The safety coefficient of woven ropes is usually equal to 7.
- Woven ropes do not have any additional ties such as knots.
- It can be verified whether it has reached a sufficient working coefficient by performing appropriate tests.
Ropes are supplied with a report after safety tests are carried out. This equipment, which should be checked at regular intervals, provides a smooth and safe use.
Which Factors are Considered When Determining the Safety Coefficient?
Problems such as rupture, tearing, puncture or abrasion threaten the safety of ropes. This situation may pose a danger to work and worker safety. The resistance of ropes to abrasion and impact plays an important role in selecting the right equipment. The purpose of this concept, also called the safety factor, is to determine the ratio between the sum of the different forces on the rope and the breaking load. Among the criteria to be considered when determining the rope safety coefficient are there:
- Static weight of the ropes,
- Dynamic weight with sudden loading weights,
- Accelerated weight, which is the power changes in the area of acceleration and deceleration,
- Rope efficiency ratio as stresses occurring at bending moments,
- Changes in the moment of vibration and winding,
- Types of cargo such as people or materials,
- Terms of use of the equipment,
- Challenges that determine the lifetime of ropes,
- Unpredictable changes due to possible usage errors.
Ropes provide convenience to workers and they are lifting equipment used in different sectors such as construction, maritime, mining or aviation. These materials used in pairs are assembled and disassembled together. A smooth and safe process can be realised by selecting the correct safety coefficient.
