Q:Which brand is better for imported rigging?

Germany's mechanical products are better, quality world-class, CarlStahl sling rigging is Germany's old brand.

Q:What is the safety factor of the wire rope as a motor lifting equipment, slings and slings?

2. galvanized steel wire rope, including hot-dip galvanizing and electro galvanized two kinds, hot galvanized zinc layer is thick, long use time, galvanized thin, zinc layer thicker, corrosion protection ability is stronger. Because of the corrosion resistance of phosphating coating, the manganese phosphating coating steel wire rope can be used instead of some kinds of zinc coated steel wire rope, such as the B zinc coating in GB8918-2006.

Q:Why do not different kinds or different sizes of slings and slings are used together?

Choose proper slings and slings according to the specific conditions of the heavy loads; no heavy weights are allowed to be attached directly with the hooks, and no different kinds are allowed

Q:What does the inspection of rigging involve?

Galvanized steel wire rope, including hot galvanized and galvanized two kinds, galvanized zinc layer is thick corrosion resistant ability is strong, the thickness of zinc in grams / square meter said.

Q:Why are the suspension bridges a main cable, even a n multi sling, not a bridge directly from the tower?

The cable-stayed bridge is a cable-stayed beam with a plurality of cable on the tower bridge. It consists of beam, cable and tower is composed of three parts. The cable-stayed bridge is a self anchored system, the level of power cable by Liang Chengshou, in addition to supporting beams on the pier, also supported by the cable leads to the tower. According to the materials used in the beam, they can be divided into steel cable-stayed bridge, composite beam cable-stayed bridge and concrete beam cable-stayed bridge.Cable stayed bridge is one of the most popular types of long-span bridges in china. So far, there are more than 3O cable-stayed bridges completed or under construction, second only to Germany and Japan, and the third place in the world. And the number of long-span concrete cable-stayed bridges has been ranked first in the world.In the middle of 50s, the first modern cable-stayed bridge was built in Sweden. For more than 40 years, the development of cable-stayed bridge has a strong momentum. In the middle of 70s, China began to build concrete cable-stayed bridges. After the reform and opening up, the momentum of the construction of cable-stayed bridges in China has been on the rise.

Q:Do cranes have the same wire ropes, slings, slings and cables?

My understanding is different. The cable refers to the cables used for power supply or the cables used for hanging lamps.

Q:What are the specifications for the rigging?

The wire rope for the first time in the field of fretting fatigue control measures is the phosphating coating steel wire rope patent technology production, steel wire after manganese phosphating or zinc manganese wear-resistant steel wire surface treatment, corrosion resistance to enhance, not easy to wear and corrosion fatigue life of the steel wire rope large increase, fatigue life is three as structure of plain steel wire rope, the highest value of contrast test has reached an alarming four times, can be verified by fatigue test, fatigue test machine if they have on their own to do comparative tests, this test results most credible, the service life of wire rope and the fatigue life is directly proportional to the fatigue life, long service life with the proportion of prolonged use of lower cost, better stability, phosphating coating of steel wire rope is patent technology production

Q:Requirements and matters needing attention in hoisting

Hoisting tower tank by using rotary method or down method, wrist hinge at the bottom of the tower installation must have the ability level of the thrust generated resistance during lifting, the lifting process of the tower body around the ropes must be reliable, the tower height of the rotary position, slowly falling into the foundation, avoid accidents and deformation.

Q:What tools are slings in lifting operations? What is the function of the slings?

Sling is one of the most common operation tools in hoisting operation.

Q:Is the sling the same thing as the rigging?

I say you should be able to understand the sling, lifting heavy rigid fetching device operation means, that is to say can directly take hanging items, mainly include: grab, clamp, suction and special sling and rigging, etc.; refers to the lifting items, tie hook combination device with flexible. In the article, usually made from high strength flexible parts (steel wire rope, lifting chain, artificial fiber tape) with end ring, hook, shackle assembly.
