Q: Where should I pay attention to the formwork?: (1) Kennedy to support part of the template and scaffold, when installed in the soil on the plate should be added, and the foundation must be solid and drainage measures of collapsible loess, there must be waterproof measures; frost heaving of soil is stopped, there must be anti freeze thaw measures.(2) in the course of installation of the formwork and its support, the temporary fixing equipment should be set up.

Q: What is the influence of lifting angle on rigging?: Slings are usually steel wire ropes or chain slings. Wire ropes have manganese phosphating coating, steel wire rope, galvanized steel wire rope, manganese phosphating coating, steel wire rope is new technology product, and fatigue life is three times of smooth steel wire rope.

Q: What is the line on the train for?: The catenary provides 25 thousand volt power frequency alternating current for the locomotive, according to the locomotive model difference, adopts the direct step-down, the frequency conversion power supply or the AC and DC conversion power supply, this is mainly for the speed regulation convenience.

Q: Do cranes have the same wire ropes, slings, slings and cables?: To be exact, different things are very relevantThe cable belongs to the sling and belongs to the spreaderA wire rope can be made into a wire rope rigging

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: Requirements and matters needing attention in hoisting: We often encounter equipment installation, transport and installation work, whether the derrick is lifting or hoisting machinery should pay attention to the following points: (1) the indigenous construction equipment for handling mobile rolling method, the rolling rod thickness should be consistent, should buetow annual row width is 50cm long, no gloves in rollers. While loading and unloading piping shall not be greater than 20 degrees slope, raceway erection should be smooth, solid, joints staggered, the rolling speed is not too fast, when necessary to use ropes.(2) in the course of installation, if problems are found, measures should be taken in time, and then continue to be hoisted after treatment.(3) large tower equipment for hoisting derrick, hoists joint operation, the hoist hoisting speed must be roughly the same, to ensure that the tower body of each suspension force roughly uniform, avoid the tower stress uneven deformation.

Q: What's the sling for a movie?: WIA, is used to protect the athlete's device is generally with a strong rope tied to the athlete's protection belt.

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 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: Slings and rigging manufacturers, which cost-effective?: Crane users need high quality steel wire rope, it should be long life and high quality stable and reliable wire rope. The use of wire rope in the atmospheric environment, mainly caused by the failure of wire rope is fretting fatigue, at present, the wire rope for the first time in the field of fretting fatigue control measures is the phosphating coating steel wire rope patent technology production, steel wire after manganese phosphating or zinc manganese treatment, wear resistance, enhance the surface of steel wire that is not easy to wear and corrosion fatigue life of the steel wire rope large increase, fatigue life is three times the same structure of plain steel wire rope, the highest test value has reached an alarming four times contrast (laboratory comparable conditions), can be verified by fatigue test, fatigue test machine if they have on their own contrast test, this test results the most credible, the service life of wire rope and the fatigue life is directly proportional to the fatigue life, long service life of the same proportion of extension.
