Q:Types of slings for slings
Slings are mainly made of metal slings and synthetic fiber slings in two main categories.
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: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?
Crane operation is relatively dangerous, the installation of crane beam should be standardized to ensure the safety of crane operation. How many points should I pay attention to when installing the crane?:(1) the actual elevation of the corbel should be measured before the installation of the steel crane beam, so that the construction error of the elevation can be adjusted when the crane beam is installed, so as to prevent the error accumulation.The installation sequence of crane beam is as follows: installing crane beam, installing auxiliary truss and installing brake beam.(2) crane shall be used by slings, lashing or reliable clamps. The binding point shall be determined according to the weight and length of the crane beam. Generally, the angle of the sling shall be greater than 45 degrees at the ends of the center of gravity of the crane beam.(3) should be placed after the crane beam, the connecting plate is connected with the fixed edge plate and column crane girder structure, to prevent the crane hook loose after crane girder longitudinal and lateral movement of dumping.(4) crane beam correction should be performed in all bolts after installation, to prevent the installation of bolts when the crane beam shift change; prohibited welding in the crane girder under the flange and web on suspension and fixture.(5) adjust the elevation of the crane beam, correct the center line and span after titanium.
Q:Why do not different kinds or different sizes of slings and slings are used together?
Or different specifications of slings and slings are used together; the carrying capacity of the sling shall not exceed the rated lifting capacity; the sling shall not exceed the safety load; the lifting crane shall check whether the connection point is firm and reliable
Q:Is the sling the same thing as the rigging?
As for your concept, I have also struggled with it before. I also consulted the professionals who were applying the rigging.
Q:What is the name of the wire above the train?
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 is the safety factor of the wire rope as a motor lifting equipment, slings and slings?
2. galvanized steel wire rope, including hot-dip galvanizing and electro galvanized two kinds, hot galvanized zinc layer is thick, long use time, galvanized thin, zinc layer thicker, corrosion protection ability is stronger. Because of the corrosion resistance of phosphating coating, the manganese phosphating coating steel wire rope can be used instead of some kinds of zinc coated steel wire rope, such as the B zinc coating in GB8918-2006.
Q:Where should I pay attention to the formwork?
When the welded steel bar and the formwork are installed together, the following requirements shall be met:The formwork must be fixed on the joint of the load-bearing welded steel frame;When installing the reinforcing steel formwork assembly, the sling shall be tied up according to the hanging point designed by the template.
Q:Notice of tower crane?
The metal structure of the tower crane, the track and the metal shell of all the electrical equipment shall have reliable earthing devices, and the grounding resistance shall not be greater than 4 ohms, and lightning protection devices shall be set up.Fourth. Pole arrangement, each attachment device attached to the wall and spaced distance should be in accordance with the provisions of the original factory, homemade bar design calculations should be.
