Issues and Solutions for Container Bags: Problems with Strap Breakage Accidents (2)
Insufficient strength of components against the required load capacity poses a risk of accidents! Introducing the standard values from JIS standards!
The lifting belt, which can be considered the lifeline of the container bag, supports the load and excels in tensile strength, but it also has weaknesses. Let's discuss the causes of accidents where the belt breaks. If the strength is reduced to lower the product price or if weather-resistant agents are not added, the risk of accidents increases. Container bags have safety strength requirements for use defined by the JIS standard JIS-Z1651. It is required to clear load tests based on the total strength of the lifting points, not just the strength of the lifting belt alone, which determines the tensile load required for the belt's intended use. At Naikai Corporation, we confirm the strength data of the yarn during production and regularly conduct official testing at Japanese industrial testing laboratories to ensure safety.

basic information
【Overview】 ■Material performance of lifting belts and ropes: Initial strength (F≧s×W/n) ■F tensile strength (N) ≧ material safety factor s (cross single ⇒ 6) × maximum filling load (1000kg) / number of belt suspensions (4 points) ■In the case of a 70mm beige belt, with a filling of 1000kg and 4 support points: ・《F (N) ≧ 6 × 1,000kg (= 9,800N) ÷ 4 = 58,800N ÷ 4 = 14,700N (1500kg)》 *For more details, please refer to the PDF document or feel free to contact us.
