- Q: What are the dangerous sections of the crane hook?
- B -B and A-A section section of the same, B -B section in the sling tension loading, have been straightened and cut off the trend here, shearing stress is maximum, it is also dangerous section.
- 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: Which brand is better for imported rigging?
- Germany's mechanical products are better, quality world-class, CarlStahl sling rigging is Germany's old brand.
- 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: What are the precautions for rigging in hoisting works?
- 1. develop good hoisting habits and plan how to hang, lift and unload before lifting.2. prepare: determine the weight of the hanging object and its center of gravity, read the attached document carefully, mark the lifting point and weight data. Only when the center of gravity has been determined can the hook be hung at the right place!3. the crane operator shall be informed of the weight of the suspended object.4. the crane hook shall be hung vertically above the center of gravity of the suspended object.5. lifting heavy pieces, both to avoid damage to lifting objects, but also to prevent damage to the rigging itself. The following conditions shall be observed in order to avoid rotation or fall:(a) single leg rigging, the lifting point shall be perpendicular to the center of gravity of the lifting object.(b) if it is a two leg rigging, the suspension point shall be on either side of the lifting object, with the lifting point above the center of gravity.(c) if it is a three leg and four leg rigging, the suspension point shall be evenly located at the center of gravity of the lifting object, and above the center of gravity of the suspended object.Attention must be paid to the lifting angle, between the vertical and the leg): the greater the lifting angle, the smaller the lifting capacity. Lifting angles of more than 60 degrees are absolutely not allowed!
- Q: The wire rope lock can hang a lot of things
- Ask the manufacturer of the rope sling. The tension of the sling is eighty-five percent of the wire rope, then divided by the safety factor 6. The pulling force of the wire rope is related to the wire rope structure, diameter and intensity level. It is for reference only.
- 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: Is the sling the same thing as the rigging?
- I say you should be able to understand the sling, lifting heavy rigid fetching device operation means, that is to say can directly take hanging items, mainly include: grab, clamp, suction and special sling and rigging, etc.; refers to the lifting items, tie hook combination device with flexible. In the article, usually made from high strength flexible parts (steel wire rope, lifting chain, artificial fiber tape) with end ring, hook, shackle assembly.
- Q: What are the specifications for the rigging?
- Because the demand is more difficult to buy, to ask the producer of several wire rope, please note in the purchase, purchase invoice must indicate the name of wire rope, such as phosphate coated wire rope, prevent illegal infringement of their legitimate rights and interests of enterprises, in addition, patent products are generally in the rope on the outer packing of a patent spraying mark, warranty due the main technical indicators, such as the phosphating film type and film weight (have an important impact on the weight of phosphating film size, wear resistance and corrosion resistance of the service life of the wire rope, for reference only)
- 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.
