Q:What tools are slings in lifting operations? What is the function of the slings?
A sling is also called a jack rope, a pair of rope or rope buckle. Hoisting works are more used, such as tying equipment, hanging blocks, stabilizing winches and so on. The utility model has the advantages of good quality and large elasticity, but the rigidity is large, and the bending is not easy, and once the bend is not easy to recover. Slings made of wire ropes of hemp core are not easy to work under high temperature.
Q:How much is the crane arm of the tower from the residential building recently?
No aluminum conductor or steel shall be used as grounding or ground wire for the installation of tower cranes. A bolted wire must have an end. Grounding is mainly made up of the following three ways:1. the grounding body adopts a regular grounding pile, or a 33*4.5 long 1.5m steel tube, or a 70*70 long 1.5m angle steel.2. the floor is made of steel plates or other metal plates with an area of 1 square meters. The ground is deep from the ground 1.5m.3. a copper conductor with a cross-section of not less than 28 mm or a steel conductor with a cross section of not less than 50 mm is buried in the slot and its embedment length is determined by the grounding resistance.In the above three ways, the grounding body leads the copper conductor, the sectional area shall be no less than 25, if the soil is not conductive, the sodium chloride (salt) can be embedded in the soil. Then irrigation. For walking crane, each rail must be grounded, and the two tracks are connected by wires. Electrical connections should also be made between the two rails, with a resistance of no more than 4.
Q:What is the safety factor of the wire rope as a motor lifting equipment, slings and slings?
1 phosphating coating steel wire rope (patent products), steel phosphating manganese or zinc manganese by wire surface is very wear-resisting, effectively inhibit the occurrence of fretting wear, is a substitute for plain steel wire rope upgrade, service life far beyond the structure of smooth steel wire rope, wire rope including imported from developed countries such as Germany and Japan (currently the rope is about three times of phosphating, smooth rope after may also be able to improve the phosphating film 3-60 g / M 2, wire drawing no longer after phosphating processing, direct twisting wire rope), has been in China copycat wire rope technology innovation. The innovative technology is suitable for almost all kinds of high-quality carbon steel wire rope varieties, such as elevators, steel ropes, important use steel wire rope and so on.
Q:They are used for slings, ropes, chains, suspenders, hand hoists, right?
The steel rope, chain and sling belt can be directly used as slings, and the hand chain hoist can not be used as slings.
Q:What are the installation steps for crane beams?
The crane beam and track shall be corrected after the main component is fixed. Fix immediately after correction, in order of fixation, bolt first and then weld.
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:What's the catch?
The type of slings 1. slings are mainly metal slings and synthetic fiber slings in two main categories. 2. metal slings are mainly wire ropes, slings, chains, slings and so on. 3. synthetic fiber slings are mainly made of nylon, polypropylene, polyester, high-strength and high modulus polyethylene fiber for rope and belt slings.
Q:What are the specifications for the length, length, and method of operation of the wire rope?
Users need high quality steel wire rope, it should be long life and high quality stable and reliable wire rope.
Q:What is the name of the wire above the train?
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:Requirements and matters needing attention in hoisting
When the equipment is mounted on a frame or a building, its strength and stability shall meet the requirements of the installation conditions. In equipment installation and location according to the requirements of the drawings are tightly connected or welded, meet the design requirements of the strength and has stability, can be decoupled, otherwise they should be temporary fixed 1. security measures, to prevent the crane from tilting measures (1). The lifting scene road must be smooth solid backfill, soft soil should be processed. If the soil is soft, roads should be paved separately. Parking crane is not working on a slope, also does not allow the crane two side high.
