- Q:What are the specifications for the length, length, and method of operation of the wire rope?
- The fatigue life is three times the same 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 life ability if they have on their own to do comparative experiments, this test results the most credible, the service life of wire rope and the fatigue life is proportional to a long fatigue life use the same proportion of life extension, the use of lower cost, better stability.
- Q:Notice of tower crane?
- When the wind is above four, no lifting, installation or disassembly shall be carried out. Check the connection of all parts of the hydraulic jacking system before jacking up. No swing arm and other operations are prohibited during jacking.
- 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's the catch?
- Slings are ropes made of wire or synthetic fiber, used for hoisting.
- 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:What is the difference between cable stayed bridge and suspension bridge?
- The main weight of a bridge is not the car or train on it, but the road itself, that is, the road we see. Now let's analyze this:We analyze it with a pylon. The two sides of the pylon are symmetrical stay cables which connect the main beam of the pylon through the stay cables. Now suppose that only two towers on both sides of the cable, symmetrical each one of the two cables subjected to beam gravity, two symmetrical of the cable along the direction of the force, according to the stress analysis, the stress can be decomposed into a horizontal and vertical force to a downward force a vertical force; and the same on the right side of the force can be decomposed into the right level of a downward force; the two force is symmetrical, so the two level of the left and right horizontal force cancel each other out,
- 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: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: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:Is the sling the same thing as the rigging?
- This is not strictly divided, if not to say that the rigging refers to those parts of the spreader is rigging, such as rings, ring buckle, hook, shackle. The sling is a wire rope, lifting chain, lifting belt, these rigging consisting of a complete set for lifting tools, that is, sling. In practice, the two are inseparable. So they are generally called rigging companies. Hope to help you, which is the media, and have the opportunity, please welcome to interview our company.
