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:How many meters of cranes should be in accordance with the anemometer?
The state specifies the installation of wind speed meters for outdoor cranes!AskMore than how many meters need to be installed, or as long as it's outdoor, it needs installationChasing the answerThe provisions of the People's Republic of China national standard GB 6067.1--2010:9.6.1.1 high speed cranes for outdoor work shall be equipped with an anemometer. The anemometer shall be installed on the windward side of the crane.9.6.1.2 high speed cranes for outdoor work should be equipped with an air speed alarm that displays instantaneous wind speed, and when the wind speed is greater than the working wind speed setting value, the alarm signal should be sent out.
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 is the calibration value of a tower crane?
Tower crane calibration value is to benchmark material to be calibrated by standard liquid titration value, calibration to parallel mark three times, take the average value, if the requirement is not strict, error within 3 per thousand, strictly within 1 per thousand.Main performance parameters of tower crane:1. Lifting weight G1. weight G - was the quality of the heavy lift. The unit is t.2. rated lifting weight Gn allows crane lift weights together with the quality of the sum of the spreader.3. maximum weight Gmax - normal work conditions under the crane, the maximum permissible rated lifting weight lifting.Two, range LL - 1. range of level ground when the crane is positioned between the spreader, no-load vertical center line to the center line of the rotary horizontal distance. The unit is m.2. biggest Lmax - crane, jib angle or the minimum car in arm the limit position of the amplitude.3. Lmin minimum amplitude - jib angle or trolley jib in maximum limit position within the range.
Q:How to calculate the pouring and maintenance of tower crane concrete in valuation?
Fixed price can be fixed. According to the design of construction organization. For a fixed item, reflected in engineering construction scheme.List price of the project, the quotation, measures, fees, quotations.
Q:What kind of bodies are tower cranes made of?
Two. The metal structure of tower craneThe metal structure of tower crane is mainly composed of underframe, tower body, jacket, upper and lower support, suspension arm, balance arm, tower top and other main components.Metal structure is the framework of tower crane, which bears the deadweight of crane and all kinds of external loads during operation.Three. Power unit and control systemThe power unit is the power source of the crane, and the power source of the tower crane is an electric motor with an external power supply.The control system includes controls and safety devices. Control device for tower crane is composed of a linkage control console, distribution box, resistor box components, the safety device is mainly composed of height limiter, amplitude limiter, lifting weight limiter, moment limiter, slewing limiter etc..Through the control system, the movement characteristic of the crane can be changed, so as to realize the starting, speed regulation, modification, braking and stopping of each mechanism, so as to achieve various actions required by the crane operation.
Q:Tower crane 10-5-20 is 6T, and 10-5-21 is 8T. What do you mean by tons?
6T/8T refers to the maximum lifting capacity of a tower crane. It doesn't matter what 10-5-20 has to do with it. Maybe your list of numbers is serial number.
Q:Protective earthing resistance of tower crane
Q:What type of tower crane does not include tower crane in variable amplitude mode?
Tower crane, tower crane.Tower crane according to its different types, there are the following classification methods.(1) divided by structure type of fixed tower crane by connecting a fixed tower in the foundation or structure, tower crane lifting operation.Mobile tower crane: a tower crane with running device and can walk.
