- 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: Is rope sling good business and high profit?
- With an annual output of 1 million 800 thousand tons of steel China ranked first in the world, is the first world phosphating wire rope wire rope surface treatment inhibited fretting fatigue to prolong the useful life (fatigue life), business wire rope and rigging, ordinary product profit, if can be linked to the manganese phosphating coating of steel wire rope, the profit is very high
- Q: What is the line on the train for?
- The contact wire is mostly made of steel aluminum core, that is, the outside is made of steel, and the main part is the friction part of the pantograph. To ensure the conductivity and wear resistance, the aluminum core is mainly to ensure the conductivity. Copper and aluminum composite wires have also been used as contact wires.
- Q: What are the dangerous sections of the crane hook?
- The sling tension A-A section on the one hand, the hook has straightened trend; also by the effect of bending moment on the other hand. Because the moment in this section, the bending stress is maximum, this section is a dangerous section.
- Q: They are used for slings, ropes, chains, suspenders, hand hoists, right?
- A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope.
- Q: What torture refers to the lever and the sling
- This is a torture peculiar to china. The knee joint has the smallest range in the major joints of the limbs, and the length of both ends of the thigh and leg is favorable to the prisoners. The lever principle is used to compel the victims with lesser intensity. Key points of anti joint using tiger stool:1, the victims in the sitting position (arms tied or tied into the penalty, the pulling force cross) it will aggravate the leg ligament, and supine position due to hip joint ligament relaxation, legs relaxed, will weaken the degree of pain;2, the leg is tied in the lap of the thigh, rather than the following parts. Because the function of the tiger stool is to pull the joints and ligaments of the victim's leg and to cause a dislocated knee, not to break the victim's leg. Because the broken leg, the fibula needs a lot of power, the pain time is short (the victim will soon fainted), do not meet the punishment, both to torture the victims and their own labor saving requirements.According to records, when the victim is on a tiger stool, he usually gets sweaty when he pad three bricks. When the five bricks are completely dislocated, the person will faint. The torturer usually each brick will be suspended for a while, the victims of the pain continued for a period of time after aggravated torture efforts. Women's ligaments are usually softer than men, so they suffer longer on tiger stools and tend to faint when they are added to six bricks, the longest of which is eight bricks.
- Q: Ceiling installation does not allow the use of air nails?
- Connection of hanging cup, sling and structural layerOperation method: (1) the main consideration connected with embedded parts and transition piece.In the first layer in embedded iron or wood brick (except water brick). The location shall be accurate and adequate adjustment should be made.The transition in the iron and wooden fittings, so as to adjust the mindware error, and mindware nail, screw, welding, wear.The suspender and the sling are connected with the transition connecting piece.
- Q: How do you tie the wire rope?
- A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope double - phosphating coating.
- Q: What are the selection principles for lifting cranes?
- To avoid the use of large lifting capacity of the crane lifting capacity of small parts, small crane overload lifting component, or choose not modified after the actual loading test of crane hoisting, shift or use the high cost of equipment.
- Q: What are the installation steps for crane beams?
- Installation of crane beam elevation as a negative deviation, between surface and column bracket crane beam flange into the iron plate. But the shim shall not exceed three layers and shall be placed under the end of the crane beam or under the stiffener, and the area of the shim shall not be less than 60% of the part of the contact area between the crane beam and the bracket.
