Q:National standards for tower cranes
GB/T 5031-2008 GB 5144-2006 tower crane safety code for tower crane safety GB mechanical and electrical equipment thirty-second 5226.2-2002 mechanical parts: requirements for hoisting machines GB 5802-1986 lifting short chain hoists and other lifting equipment for the T (8) test specification level calibration chain GB 5905-1986 hoisting machine test code and procedures GB/T 5905-2011 crane and GB/T program 5972-1986 lifting wire rope for examination and discard utility specification GB/T 5972-2006 crane wire rope inspection and scrap utility specification GB/T 5972-2009 crane wire rope maintenance, maintenance, installation, inspection and disposal GB/T 5973-1986 wire rope with wedge joint GB/T 5973-2006 wire rope with wedge joint
Q:What is the power of a tower crane? Five
TC7525-16D switchboard power 80KWTC5610-4 switchboard power 34KW.TC6015A-10E switchboard power 71.5KWThe other two types have not been touched and will not be answered. I'm sorry
Q:What does the lifting mechanism mean in a tower crane?
Magnification, in simple terms, refers to several ropes through the hookIf it is one in and out of two wire rope, that is two magnificationSimilarly, two into two out is four magnification
Q:Emergency treatment of interrupted electricity during lifting of tower crane
When the power supply fails, you should first remove the things that are stuck in the gear!
Q:What parameters are lifting machines called large equipment? 200
General purpose gantry cranes: MG, 440t, MG, 360t, MG, 450t, Me, 360t, ME, 900tGeneral purpose bridge crane: QD, 350t, QD, 400t, QD, 450t, QD, 390t, QD, 330t, QE, 350t, QE, 330tThe above tonnage is now recognized as a large lifting machinery.Hoisting machinery refers to the lifting of heavy objects with hooks or other lifting devices, and mechanical operations such as lifting and moving in space. There are many classifications of cranes, such as cranes, cranes, cranes, cars and so on. They are commonly referred to as one or more kinds of cranes.
Q:What should be included in the disassembly plan of the tower crane?
- 3 - tower crane demolition special program should include the following1. General situation of engineering;2, the tower crane position of the plane and elevation;3. Disassembly order;4, unit weight and hanging point position;5, remove the auxiliary equipment types, performance and arrangement position;6, the power set;7, the construction personnel configuration;8. Rigging and special tools;9, major sources of risk and safety technical measures;10, emergency plans, etc..Note: (1) the special construction plan for the installation and disassembly of tower cranes shall be examined and approved by the units, technology, safety, equipment and other departments, and shall be implemented after approval by the supervisor.(2) the contents and requirements of the special construction scheme for tower crane installation;Compiled from the "building construction tower crane installation, use and disassembly safety technical regulations" JGJ196-2010, please refer to the implementation. Attached: 1, Zhifu Wanda Plaza Tower Crane installation program 2, Muping District Cultural Center project PT7528 tower crane demolition program
Q:How to distinguish self lifting tower crane with counterweight and lifting tower crane without counterweight
1 self lifting tower cranes with counterweight are common tower cap tower cranes, plate type tower cranes and flat head tower cranes, characterized by a counterweight made of several concrete on the balance arm,
Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
In short, when the tower rotates in the form of a tower, the tower is stationary (ie does not follow the rotation), and the form of the lower turn is the tower will rotate.
Q:How to improve the stability of tower crane
Phosphating coating of steel wire rope, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just add the last bonderizing process, steel wire, wear resistance and corrosion resistance is greatly improved, the use of the wire without direct phosphating cold twisted steel wire rope.
Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you
Hook top point control: when the hook to the high limit, limit action, do not continue to hook!Overload control: when the weight exceeds the overload point or amplitude exceeds the maximum amplitude or the loading rate is more than 105% when the output control, prohibit the hook lifting action and prohibit car distance to allow the car to increase the amplitude, amplitude can be damped near.
