SHACKLES
The forging rigging factory 。 is the largest production base for forging rigging in Asia with advanced forging, heat treatment,surface coating and nondestructive testing equipment and the most advanced production technology.
Main forging equipment :5T size free forging hydraulic hammer,4000t、2500t、1000t size friction press machine and 750kg ～ 1000kg size air forging hammer etc. We also researched and developed 400t、1000t、1500t、2000t size bending machine. The annual producing
capacity is 20000t.
The shackles (both body and pin) we produce are made of high quality alloy steel through advanced production line and intermediate frequency furnace heat treatment. It is characterized by high-intensity, good toughness, small volume, light weight, beautiful appearance and good durability.
Product category: Flat shackle, Large WLL shackle with circular cross-section, Bow shackle, D shackle etc.
Production range: 0.5t-2000t
It is made of high quality alloy steel by die forging.
Each shackle will be marked with WLL permanently, WLL from 0.5t ～150t.
The Maximum testing load is twice of the working load ,while WLL is less than 85t(including),the minimum breaking load is 6 times of the WLL ,while WLL is more than 85t ,the minimum breaking load is 4 times of WLL .
Our products all correspond with the stipulated technical requirement and test approach in standard ISO2415-2004.
- 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: What are the connections and differences between hooks, slings, rings and heavy truck rings in cranes? What are the hoisting designs?
- Chain lifting sling series: high strength chain sling, single leg sling, double leg sling, three leg sling and combination sling.5. traction rope series: synthetic fiber traction belt, wire rope, traction rope, trailer rope, high tension wire, traction rope, silk rope.6. ladder series: nylon rope ladder, rope ladder, ladder, climbing ladder, closed sea rescue ladder.7., metallurgical spreader series: C spreader, bending hook, billet clamp, round bar clamp, metallurgical special sling,
- Q: What is the line on the train for?
- It's called catenary. There are two lines up and down. The upper part is called the load line, and the lower one is called the contact line. There is a sling connection between the cord and the contact wire.
- 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: How much is the crane arm of the tower from the residential building recently?
- (1) the drivers and signaling personnel of the tower cranes must be specially trained and issued certificates by the relevant departments, and attention should be paid to whether the type of tower used by the driver is consistent with the actual tower type.(2) special person special plane management, Captain responsibility system, and strict shift shift system.(3) the newly installed or repaired tower crane must perform the machine test operation according to the specifications.(4) tower crane should keep a safe distance from overhead transmission lines.(5) driver's room should be equipped with fire extinguishing equipment.
- 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: What torture refers to the lever and the sling
- China used suspension has a special method commonly used, is the only victims of hanging to toe the height, so that the victims are difficult to completely rely on the wrist or thumb under the weight of the whole body, and can not completely rely on the toes to support the body, is very painful, this is the unique China torture method.There is a special way of suspension is relatively rare, is the so-called "monkey holding pile", will be the victims before the hands (also can only bind the thumb to hold the two) was forced to bend the knee, the knee bend into a stick with a rope, lifting the stick ends (also stick to a certain height of the frame other instruments). When the victims of the buttocks, genitals and soles of the feet completely exposed, for the use of other means torturer. In this gesture, the wrist (thumb), knee joint, waist and neck will be squeezed, twisted and pulled by the weight of each part of the body. It is very painful, and Yang Kaihui has been subjected to the punishment.
- 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?
- The selection of rigging should be adapted to the kind of articles, environmental conditions and specific requirements.The sling to carry out strict inspection, in accordance with safety color to use, if found damaged sling can not be reused, need for scrap processing.The slings used for lifting operations must be of the same length.The sling shall not exceed its rated lifting capacity, and the sling shall not exceed its maximum safe working load.
- Q: Notice of tower crane?
- After the tower crane is installed, the whole machine should be inspected and adjusted, and shall be ready for delivery after passing the inspection in stages and through the whole machine. In the case of no load, the deviation of the verticality between the tower and the ground shall not exceed 4/1000.. The motor and hydraulic unit of the tower crane shall be carried out in accordance with the relevant provisions concerning the motor and hydraulic device.
