- Q:What are the specifications for the length, length, and method of operation of the wire rope?
- The fatigue life is three times the same structure of plain steel wire rope, the highest value of contrast test has reached an alarming four times, can be verified by fatigue test, fatigue life ability if they have on their own to do comparative experiments, this test results the most credible, the service life of wire rope and the fatigue life is proportional to a long fatigue life use the same proportion of life extension, the use of lower cost, better stability.
- 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:The wire rope lock can hang a lot of things
- 2. galvanized steel wire rope, including hot-dip galvanizing and electro galvanized two, in general, hot galvanized zinc layer thickness, zinc plated zinc thin3. stainless steel wire rope, 304 or 316 stainless steel based, anti-corrosion effect is very good, but expensive4. carbon coated steel wire rope, wire rope based on polyethylene, polypropylene or nylon outer coating5. smooth wire rope, short service life, sharp decline in market demand, will be phasing out the phosphating coating steel wire rope.
- 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.
- Q:What are the connections and differences between hooks, slings, rings and heavy truck rings in cranes? What are the hoisting designs?
- Chain lifting sling series: high strength chain sling, single leg sling, double leg sling, three leg sling and combination sling.5. traction rope series: synthetic fiber traction belt, wire rope, traction rope, trailer rope, high tension wire, traction rope, silk rope.6. ladder series: nylon rope ladder, rope ladder, ladder, climbing ladder, closed sea rescue ladder.7., metallurgical spreader series: C spreader, bending hook, billet clamp, round bar clamp, metallurgical special sling,
- 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:Types of slings for slings
- Metal slings are mainly wire ropes, slings, chains, slings and so on.
- Q:What is the line on the train for?
- It's called catenary. There are two lines up and down. The upper part is called the load line, and the lower one is called the contact line. There is a sling connection between the cord and the contact wire.
- Q:How much is the crane arm of the tower from the residential building recently?
- No aluminum conductor or steel shall be used as grounding or ground wire for the installation of tower cranes. A bolted wire must have an end. Grounding is mainly made up of the following three ways:1. the grounding body adopts a regular grounding pile, or a 33*4.5 long 1.5m steel tube, or a 70*70 long 1.5m angle steel.2. the floor is made of steel plates or other metal plates with an area of 1 square meters. The ground is deep from the ground 1.5m.3. a copper conductor with a cross-section of not less than 28 mm or a steel conductor with a cross section of not less than 50 mm is buried in the slot and its embedment length is determined by the grounding resistance.In the above three ways, the grounding body leads the copper conductor, the sectional area shall be no less than 25, if the soil is not conductive, the sodium chloride (salt) can be embedded in the soil. Then irrigation. For walking crane, each rail must be grounded, and the two tracks are connected by wires. Electrical connections should also be made between the two rails, with a resistance of no more than 4.
- 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
