Introduction To Rigging
rigging
A general term that includes masts, yards (mast), yards (mast), gaffers, and all ropes, chains, and equipment used to operate them.
definition
It refers to the force tool that is attached between the lifting machine and the lifting object in order to realize the object moving, and the force member that is attached in order to stabilize the space structure.
Classification of folding rigging
There are two main categories of rigging: metal rigging and synthetic fiber rigging.
Metal rigging mainly includes: steel rope sling, chain sling, shackle, hook, lifting (clamping) pliers, magnetic sling and so on.
Synthetic fiber rigging mainly includes: nylon, polypropylene, polyester, high strength and high modulus polyethylene fiber as material production rope and belt rigging.
Rigging includes: D - ring safety hook spring hook tight rigging link double - ring buckle American - style ring bolt, etc
Folding application range
Rigging is widely used in port, electric power, iron and steel, shipbuilding, petrochemical, mining, railway, construction, metallurgical chemical, automobile manufacturing, engineering machinery, paper machinery, industrial control, logistics, large transportation, pipeline auxiliary, Marine rescue, ocean engineering, airport construction, bridge, aviation, aerospace, venues and other important industries.
Matters needing attention
1. Do not use damaged rigging
2, when hoisting, do not twist, noose
3. Do not tie the rigging
4, avoid ripping sewing joint parts or overload work
5. When moving the rigging, do not drag it
6, avoid grabbing or shock load
7. Every rigging must be checked before every use
8, tapeylon has the function of resistance to inorganic acid, but is vulnerable to organic acid damage
9, polypropylene is suitable for use in the most chemical resistant places
10, nylon has the ability to resist inorganic acid, easy to be hurt by organic acid
11, nylon in damp, strength loss can be up to 1 5%
12. If rigging is to be used under conditions of possible chemical contamination or high temperature, reference should be sought from the supplier.
China's rigging market has always been the coexistence of European and American companies and domestic private enterprises, high, medium and low manufacturers.
Our rigging industry has developed rapidly in recent years, but the technical standards are not perfect, domestic enterprises produce at will, and even arbitrarily reduce the safety factor, so there are great hidden dangers in our hoisting safety. For example, our country has no current standard for transportation bundling belt. Hoisting belt is only promoted standards, there is no mandatory standard.
We must continue to develop technical cooperation with foreign countries, improve relevant technical standards and introduce relevant mandatory laws and regulations, so as to ensure the safety of hoisting and carrying goods.
China's economy has begun to recover gradually in 2010, but major manufacturing industries, such as shipbuilding, iron and steel, metallurgy, machine tools and other industries are unlikely to have great development, let alone reach the level before November 2008. Therefore, the total market volume of domestic rigging in 2010 will be higher than that of 2009. But it is unlikely to reach pre-October 2008 levels.
If a rigging enterprise wants to remain invincible or survive effectively in the tide of economic crisis, it must analyze the market trend, grasp the key point of sales, strengthen cost control and reduce inventory. In the case of market downturn, can not reduce the quality of products, to firmly grasp customers, for customers to solve problems, good technical services. Only in this way, enterprises can tide over the difficulties, through the harsh winter, ushered in a bright spring.
