1. 材质
1. material
手拉葫芦承载部件的材质优劣直接影响手拉葫芦的承载能力与安全性能，因此其材质尤其重要。日本象印手拉葫芦对于工业类用钢材的标准是非常严格的，绝大部分情况下，同类型的产品磨损程度与寿命日本的更优于国内仿造产品。
The quality of the material of the bearing parts of the chain block directly affects the bearing capacity and safety performance of the chain block, so its material is particularly important. Japan's standard for industrial steel products is very strict. In most cases, the wear degree and service life of the same type of products in Japan are better than that of domestic imitation products.
2. 制作工艺
2. Manufacturing process
工业类生产日本要早于中国，对于产品的制作工艺日本企业有着严格的标准和制造流程，且日本象印手拉葫芦的部件几乎均采用全自动化生产，这一点直接提高了产品的可靠性、降低了生产成本，除手拉葫芦组装还采用人工的方式外几乎没有其他因素干扰。
Japan's industrial production is earlier than China's, and Japanese enterprises have strict standards and manufacturing processes for the production process of products, and almost all the components of Japan's pictorial chain block are produced in full automation, which directly improves the reliability of the products and reduces the production cost, and there is almost no interference from other factors except manual assembly of the chain block.
3. 安全性检测
3. Safety test
日本象印手拉葫芦制造厂有着严格的检测标准，对于主要部件的承载检测、部分部件的材质检测、紧固件检测、磨损检测、延伸率检测、抗拉性能检测等基本参数检测都有着相当完备的流程和标准。
Japan's elephant printing chain block factory has strict testing standards. It has quite complete process and standards for the basic parameters testing of main components, such as load-bearing testing, material testing, fastener testing, wear testing, elongation testing, tensile performance testing, etc.
