WLL stands for working load limit. It is used in the field of engineering in the sense of load rating. Knowing the safe working load of any lifting equipment such as ropes, slings, lines, hooks and shackles can reduce the risk of potential danger such as rupture and tearing. This value, determined by experts in the field, is marked on the lifting equipment and supports it to work efficiently.
What Does WLL Mean?
WLL indicates the maximum load that lifting equipment such as chains and wire ropes can carry. It is determined by considering material strength, design and safety factors. It is found by dividing the minimum breaking resistance of the material by the safety factor.
The resistance of the equipment varies according to the colours. Purple has a capacity of 1000, green 2000, yellow 3000, grey 4000, red 5000, brown 6000, blue 8000 and orange 10000 kg. This value specified by the manufacturers ensures operator and work safety.
What are the Factors Determining the WLL Value?
WLL, the safe working load limit, specifies the maximum load that the lifting equipment can lift. Among the factors that determine the lifting capacity of these tools and equipment are:
- The amount of load applied,
- Length of the equipment and its line,
- Dimensions of the material,
- Equipment number, and,
- Operation speed.
WLL is determined according to factors such as connection type, material strength, design and loading angle to ensure efficient and safe use. The conditions under which the equipment is used have a determining role in the load limit. Bending or knotting of equipment selected for the load to be lifted can reduce this value. High temperatures can adversely affect the working load limit and reduce its performance. Lifting tools and equipment selected based on this value can be used in the right place.
What is the Importance of Working Load Limit?
Used in engineering and lifting operations, WLL and SWL are abbreviations for load ratings and weight limits. The actual weight must not exceed the safe working load limits to prevent failures and accidents.
Overloading conditions can pose a danger to work and worker safety. Criteria such as the material of the equipment and the load to be transported, environmental conditions and loading angle determine the working load limits. If the load exceeds the lifting capacity of the equipment, it is recommended not to use it. The working load limit of the tools and equipment selected for the area and purpose of use is also an important factor for safety.
