Q:What tower cranes are used on the 30 storey house?
but if the building steel structure more parts or building the number of square meters more than 60 thousand square meters, you need to consider QTZ80 or more of the tower crane, because the type of large lifting capacity is big, the work efficiency is high. Hope to be of help to you!
Q:Notice of tower crane
Installation condition of 3.2 tower crane3.2.1 tower crane has special equipment manufacturing license, product certification, manufacturing supervision and inspection certificate, the tower crane manufactured abroad should have product certification, and has been in the construction administrative departments for registration.3.2.2 tower cranes shall be of complete structure and conform to the provisions of GB5144 "safety regulations for tower cranes".3.2.3 under the following circumstances, tower cranes are not allowed to use:If the state has been eliminated from the designated period of time, exceeding the prescribed service life assessment, the safety devices and safety facilities can not meet the safety and technical standards of the state or industry; there is no complete safety technical file.3.2.4 tower cranes must be maintained and fully checked before they are installed. Structural parts with visible cracks, severe corrosion, overall or partial deformation, connecting shafts (pins), Kong You, severe wear and tear should be repaired or replaced, in accordance with the provisions of the installation.3.2.5 tower crane foundation should meet the requirements of the use manual, the carrying capacity of the foundation must meet the requirements of tower crane design, installation should be carried out before the hidden project acceptance, qualified before installation. Slope and drainage facilities should be built around the foundation.The track foundation and track laying of 3.2.6 walking tower crane shall be carried out according to the instruction manual and shall comply with the provisions of GB5144.
Q:Construction tower crane driver (T) Ben can be used as construction crane driver (S)?
Building crane driver (T); tower crane driverConstruction crane drivers (S); construction elevator drivers; neither is common.
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:What are the types of common tower cranes?
(3) according to erection methodNon self erecting tower crane: a tower crane assembled and erected by other lifting equipment.Self erecting tower crane: a tower crane that relies on its own power unit and mechanism to realize the transition between the transportation state and the working state.(4) according to variable amplitude methodThe trolley jib tower crane lifting trolley along the tower crane luffing boom for operation.Boom luffing tower crane: luffing tower luffing luffing luffing crane.Folding tower crane: tower crane which can be bent by boom according to the needs of lifting operation. It can also have the performance of luffing and luffing.
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
First of all, your engineering structure is reinforced concrete Or steel? What's the weight of the lift? The lifting capacity of tower cranes should meet the needs. Generally speaking, steel structure hoisting, tower crane of the largest lifting weight and gravity moment should be large; hanging steel reinforcement of a smaller can.Secondly, the boom length should be covering the scope of construction (can also be arranged to meet several sets of crane lifting coverage). But in the 360 level luffing jib range, can not have obstacles (other cranes and buildings), and the boom and the distance between them (below) should be not less than 2m.Third, in the construction project is relatively high, the site is relatively small, you can mount the internal climbing tower crane. Building covers a large area, sometimes one can solve the problem. Of course, it is more troublesome to disassemble and lift inside, but the standard section used is less and the cost can be lower.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:How about the installation and disassembly of the tower cranes?
Authorized by the national security inspection department, the local special operations training school or the technical quality supervision bureau, after the study, assessment, qualification and graduation permit, will give you special operations installation, removal operation certificate.
Q:What windproof devices should be set up for crane work?
4. windproof anti-skid safety deviceThe utility model is a safety device for preventing the crane of the open-air work from sliding along the track under the action of strong wind, and the outdoor working track type crane shall be installed. The safety function of the utility model is that when the crane encounters the maximum wind force in the non working state, the crane is not blown to prevent the crane from overturning at the end of the rail. Common windproof devices include rail clamps, anchoring devices, and iron shoes.(1) rail clamping device: it is widely used in all kinds of outdoor track crane, its working principle is to use the two sides of a clamp rail head, the crane is fixed on the track through the combination of the clamping force, the crane can not slip. The design requirements of rail clamp, clamping force of rail clamp must be greater than the crane sliding force, to ensure that the local maximum wind, crane stays closed; rail tongs should rely on device components own weight or spring, and should not only rely on the driving effect of the power of the driving device, to to prevent the power supply is interrupted, the rail clamping device does not work; power driven rail clamping action should be behind the operation mechanism of brake action violently to eliminate possible crane brake.(2) anchor device: it uses a bolt or a flashboard device, a chain or a top pole to connect the crane and the track foundation into one body, and is used for fixing the crane in the big storm when not working. Since the anchor device can only be located in a certain position of the track, the crane can be anchored to this position, which is not suitable for immediate weather protection in an emergency.(3) iron shoes: it is a wedge device, when used, the wedge-shaped tongue inserted between the wheel tread and rail top surface, the iron shoes of the slope constitute the resistance to sliding wheels.
Q:What is the brand of ZOOMLION tower crane?
This is not very good answer, the United States originally used Tianshui 213, and then used the Japanese MITSUBISHI, used Schneider, LG, star power, Eaton.How big is the lift? It depends on the size of the motor you use. 24KW motor, the choice is about 100A. 30KW uses 125-150A, 55KW, and 150-180A;Generally 40A contactor is used for turningCar selection of 25A on it.
