Product Range:Chain sling factory mainly produce high-tensile lifting chain, high-tensile chain sling, round link chain and steel compact chain for scraper conveyor and auxiliary part for mine chain.
Equipment:Chain factory has chain making machine, flash butt welder, stretcher from WaFiOs (german) and sPEcTROMaXx brand metallurgical analysis spectrograph.With the expansion of the market share in recent years, the factory has built 17 chain production lines, 3 chain sling assembly lines and 2 ring welding lines.
Scientific achievements:Mining chain obtained Ma certificate. Lifting chain obtained cE certificate and participated in the compose of GB/T24816 “Short link chain and hoists lifting chain with grade eight ordinary precision chain”. The chain adopts high-quality special steel material from the domestic and foreign market and produced in accordance with the standard of En818-2, gB/ T24816-2009, GB/T12718-2009, Q/JL018-2012.Production range is Φ6-Φ48mm.。
Angle β≤45°when the chain sling was used. If unspecified it defaults to the value. Angle βis the angle between chain segments and the plumb line
- 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:What are the installation steps for crane beams?
- Crane operation is relatively dangerous, the installation of crane beam should be standardized to ensure the safety of crane operation. How many points should I pay attention to when installing the crane?:(1) the actual elevation of the corbel should be measured before the installation of the steel crane beam, so that the construction error of the elevation can be adjusted when the crane beam is installed, so as to prevent the error accumulation.The installation sequence of crane beam is as follows: installing crane beam, installing auxiliary truss and installing brake beam.(2) crane shall be used by slings, lashing or reliable clamps. The binding point shall be determined according to the weight and length of the crane beam. Generally, the angle of the sling shall be greater than 45 degrees at the ends of the center of gravity of the crane beam.(3) should be placed after the crane beam, the connecting plate is connected with the fixed edge plate and column crane girder structure, to prevent the crane hook loose after crane girder longitudinal and lateral movement of dumping.(4) crane beam correction should be performed in all bolts after installation, to prevent the installation of bolts when the crane beam shift change; prohibited welding in the crane girder under the flange and web on suspension and fixture.(5) adjust the elevation of the crane beam, correct the center line and span after titanium.
- Q:What torture refers to the lever and the sling
- The sling hanging and torture half pig "(only one side of the body hanging victims), pawn (tied hanging arm and feet) and so on, all belong to the suspension of torture throughout human skin nerve endings, the feeling is very sensitive, in the daily life of people on the outside of the pain, is the nerve end suspension shoot at work. Some nerve endings, such as fingers, toes, sexual organs, etc., are more acute and abnormal. The distribution of the human nerve network also forms many subcutaneous sensitive areas, such as the two sides of the spine, the armpit, the medial thigh, the two rib, and so on. Therefore, the users of torture also torture people according to these physiological characteristics of the human body, and bring great suffering to the sufferers with more labor-saving means. The vast majority of the torture we know fall into this category, and the torture against women is basically the same.
- Q:What are the specifications for the length, length, and method of operation of the wire rope?
- The use of wire rope in the atmospheric environment, mainly caused by the failure of wire rope is fretting fatigue, at present, 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 treatment, wear resistance, enhance the surface of steel wire that is not easy to wear and corrosion resistance of the fatigue life is greatly improved
- Q:20 tons sling rope, steel wire or chain?
- The strength of the steel wire rope can reach 2000-2500MPa, and is made by using cold drawn steel wire. The tensile strength is much higher than that of the chain, so that the weight of the sling can be reduced, the production efficiency can be higher, and the steel wire rope is preferred.
- Q:Why are the suspension bridges a main cable, even a n multi sling, not a bridge directly from the tower?
- Cable-stayed bridge, also called cable-stayed bridge, is a bridge that uses many cables to directly pull the bridge on the pylon. It is a structural system composed of a pressure tower, a tensile cable and a bent beam. It can be regarded as a multi span elastically supported continuous beam instead of a pier. The utility model can reduce the bending moment in the beam body, reduce the height of the building, lighten the weight of the structure and save the material.The cable-stayed bridge is composed of pylon, main girder and stay cable.
- Q:What are the selection principles for lifting cranes?
- Selection should take into account the performance of the crane (ie operation capacity), ease of use, hoisting efficiency, hoisting capacity and duration requirements.
- Q:Do cranes have the same wire ropes, slings, slings and cables?
- A steel wire rope is a common wire rope, and a sling is a special tool for lifting some goods. The sling is a sling tool made of wire ropes
- Q:What are the dangerous sections of the crane hook?
- ) C -C section of the section is the thinnest part of the hook column in a sling tension, have pulled off the trend. Here the maximum tensile stress, it is also dangerous section.
- Q:How much is the crane arm of the tower from the residential building recently?
- (1) hook safety device: a sling that prevents the hook from slipping and is automatically slipped from the hook. A spring is arranged at the opening of the hook head to seal the opening; the spring sheet can only be pressed downwards and can not be turned upwards after being put into the sling to prevent the sling from falling off automatically.(2): reel insurance device is effective measure to prevent accidents caused by improper wire rope winding drum out outside. There are different ways to do this. The main reason is that a steel bar is welded outside the drum to restrict the wire rope to move within the reel range.(3) fixed foundation: the depth of digging pit is 600mm, the concrete is poured on the lime soil, the surface is smooth, and the waterproof and earthing protection measures are adopted.
