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 tools are slings in lifting operations? What is the function of the slings?
- Sling made forms are more commonly used in engineering with inserting end ring and inserted nonpolar (Universal) slings in hoisting work are the steel wire rope is connected with a hook, shackle, sling made of various styles, for lifting, or binding.
- Q: What is the difference between cable stayed bridge and suspension bridge?
- Finally, the gravity of the main beam becomes the two vertical force of the tower, so that the force passes to the pier under the tower.There are more cables, and the same reason. There are a lot of bars, that's to distract the main girder from the cables.As a kind of cable of cable-stayed bridge, more than beam bridge spanning capacity is the main bridge of long span bridges. The cable stayed bridge is composed of many cables which are directly connected to the tower. The cable-stayed bridge is composed of pylon, main beam and stay cable. The types of pylon are A, inverted Y, H and single column. The materials are steel and concrete. There are single cable plane, parallel double cable plane and inclined cable plane in the stay cable. The first modern cable-stayed bridge was built in Sweden in 1955 and has a span of 182 meters. At present, the largest span cable-stayed bridge built in the world is the Normandy bridge in France, with a main span of 856 meters. The Shanghai Yangpu bridge, built in 1993, is the largest cable-stayed bridge in China, with a main span of 602 meters
- Q: Is rope sling good business and high profit?
- The atmospheric environment should be optimized by the manganese phosphating coating steel wire rope, and the heavy corrosion environment should be preferably galvanized - phosphating double coated steel wire rope.
- 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.
- Q: Ceiling installation does not allow the use of air nails?
- Installation notes: installation should pay attention to the following three points.When installing, if there are many chandeliers, we should pay attention to their location, length and length, and install the ceiling lamp while installing the ceiling, so that the position and height of the lamp can be adjusted on the basis of the ceiling and joist.The hanger on the ceiling must be made by direct out method and by adding bushing. The method of adding sleeves is good for installation, and it can ensure the integrity of the ceiling panel. The boom that is directly out of the ceiling can not be easily drilled when installing, and sometimes the method of installing the suspender first and cutting the hole of the panel is adopted, but the decorative effect is affected.The boom should have a certain length of thread for adjusting height. Attention should be paid to the reliability of the hanging light box under the suspender and suspender.
- 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 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: How to choose the right sling?
- Commonly used slings and slings are lifting belts, lifting chains and wire ropes. Slings and slings must be matched with lifting equipment, such as 5 tons or 10 tons. Cranes shall be marked with maximum lifting weight. Lifting belt will not damage the hoisting object but poor wear resistance, easy maintenance but large weight lifting chain, rope buckle range but the broken wire after easily scratch objects and operators, each have advantages and disadvantages, to meet their own needs is the best lifting.Phosphating coating of steel wire rope production technology patent, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just increase the steel wire wear phosphating process, phosphating of steel wire surface after the abrasion resistance and corrosion resistance is greatly improved, the use of direct phosphating steel wire twisting steel wire rope (steel wire after phosphating not drawing). The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3-4 times the same structure of plain steel wire rope, wire rope is 2-3 times of imports (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility of. Manganese phosphating is wear resistant phosphating, which can completely solve the wear problem in the use of wire rope.
- Q: Notice of tower crane?
- Tower cranes shall not operate near overhead transmission lines. If they are limited to field conditions, they must take safety measures when operating alongside the line. The safe distance between tower crane and overhead transmission line shall comply with the regulation.
- Q: Types of slings for slings
- Slings are mainly made of metal slings and synthetic fiber slings in two main categories.
