Pulley product overview
A tackle is a tool used for lifting, moving and hauling, usually consisting of a series of interconnected wheels and frames to reduce labor intensity and improve work efficiency. A wide variety of blocks, including lifting blocks, cable blocks, I-steel blocks, etc., are widely used in construction, power, transportation and other fields. Next, we will introduce the use characteristics, rule parameters, quality standards and other content of the pulley in detail.
Use characteristics of the block
The utility characteristics of the block depend on its design and construction, for example, the lifting block is mainly used to lift heavy objects, while the cable block is designed for cable laying. The material of the block is usually aluminum alloy, cast steel, iron, etc. The choice of these materials will affect its durability and scope of application. In addition, the pulley has various forms, such as single wheel, double wheel, three wheel, etc., and different forms are suitable for different use occasions and load requirements.
Block rule parameters
The regular parameters of the block include its size, bearing capacity, wheel diameter, material and so on. For example, the type of steel block may indicate its wheel diameter and carrying capacity, such as Φ100×31, Φ120×35, etc. These parameters determine the application scenario and work efficiency of the block.
Quality standard for tackle
The quality standards of blocks relate to their manufacturing, inspection and testing methods. For example, GB/T 31452-2015 "Lifting rigging National Standard" specifies the design, manufacturing, use and inspection requirements of lifting rigging to ensure the quality and safety of the block. In addition, there are standards for specific types of blocks, such as GB/T 9007.1-1999 "Lifting block types, basic parameters and dimensions" and so on.
1. Lifting blocks are usually used in construction sites, port docks and other places for lifting heavy goods. Its compact structure, light weight, easy to carry and operate. The wheels and frame of the lifting block are reasonably designed to withstand large loads, and are equipped with safety devices to ensure safety during use.
2. Cable pulley is mainly used in power construction, such as erecting wires, communication cables, etc. Cable blocks are usually equipped with multiple pulleys to accommodate and protect the cable while ensuring smooth and safe cable sliding. The material of the cable pulley is mostly wear-resistant and corrosion-resistant materials to adapt to the harsh outdoor environmental conditions.
3. I steel block is widely used in lifting machinery, its structure is strong, mobile flexible. The pulley and track design of the I-block are reasonable, and can withstand large transverse and longitudinal loads, which is suitable for lifting and moving heavy goods. There are various types of I-block, and suitable models can be selected according to different loads and requirements.
In summary, the block is a versatile and efficient lifting and moving tool that is designed and manufactured to meet stringent industry standards to ensure safety and reliability during use. In practical applications, the appropriate type and model of the block should be selected according to the specific needs and environmental conditions.
