Q:What does the inspection of rigging involve?
The stainless steel wire rope is mainly made of 304 or 316 stainless steel. The anti-corrosion effect is excellent, but the price is expensive4. carbon coated steel wire rope, wire rope based on polyethylene, polypropylene or nylon outer coating5. smooth wire rope, short service life, the market demand is declining, the phosphating coating steel wire rope round out.
Q:Which sling manufacturer is more reliable?
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:Slings and rigging manufacturers, which cost-effective?
Wire rope rigging, manganese phosphating coating steel wire rope is a new technology appearing in recent years. Wire rope has a long service life. Buy wire rope made of phosphating coating steel wire,
Q:What are the dangerous sections of the crane hook?
) C -C section of the section is the thinnest part of the hook column in a sling tension, have pulled off the trend. Here the maximum tensile stress, it is also dangerous section.
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 torture refers to the lever and the sling
The sling hanging and torture half pig "(only one side of the body hanging victims), pawn (tied hanging arm and feet) and so on, all belong to the suspension of torture throughout human skin nerve endings, the feeling is very sensitive, in the daily life of people on the outside of the pain, is the nerve end suspension shoot at work. Some nerve endings, such as fingers, toes, sexual organs, etc., are more acute and abnormal. The distribution of the human nerve network also forms many subcutaneous sensitive areas, such as the two sides of the spine, the armpit, the medial thigh, the two rib, and so on. Therefore, the users of torture also torture people according to these physiological characteristics of the human body, and bring great suffering to the sufferers with more labor-saving means. The vast majority of the torture we know fall into this category, and the torture against women is basically the same.
Q:What is the difference between cable stayed bridge and suspension bridge?
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: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:What is the influence of lifting angle on rigging?
The vertical lifting is the best scheme for lifting. The smaller the angle between the sling and the vertical is, the greater the angle is, the greater the force the sling will bear. The sling will be easily broken off, which will lead to an accident, which is for reference only
Q:Is rope sling good business and high profit?
The atmospheric environment should be optimized by the manganese phosphating coating steel wire rope, and the heavy corrosion environment should be preferably galvanized - phosphating double coated steel wire rope.
