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:What are the "2 magnification" and "4 magnification" mentioned in the lifting characteristics table of tower cranes?
Popular saying: "car to hook this section of vertical distance, you see 4 wire rope is 4 magnification, you see 2 wire rope is 2 magnification.".
Q:Tower crane 5610 why is it called QTZ63?
Q is reusable, T is tower, Z is jack up, and combined is jack up tower crane. (this is the earliest known China, now the various manufacturers have their own name, some close to the French take, such as F0/23B, the tower jib 50 meters, a maximum weight of 10 tons, 2.3 tons of weight lifting arm tip)80 is the moment, the unit is t * m, (should say is the force multiplied by distance, 800kn.m) for 5613 cranes, the maximum lifting capacity of 8 tons, the boom length is 56 meters, arm tip lifting weight 1.3 tons, maximum weight in the range of 2.5 meters ---13 meters, calculation of 8 * 13=104, so the name is QTZ104, now the provisions should be a QTZ104, but before, people think is 8 tons of weight, so called QTZ80, is now available.
Q:The earthing resistance of tower crane shall not be greater than that of the tower crane
The lightning resistance of tower crane (tower crane) on the construction site shall be no more than 4 ohms.I. tower crane GB/T 5031--20085.5.5.9 lightning protectionIn order to avoid lightning stroke, the main structure of the tower crane, the motor frame and all the electrical equipment metal shell, wire metal protection tube should be reliable grounding, and its grounding resistance should be no more than 4 ohms. When multiple repetitive earthing is adopted, the grounding resistance shall be no more than 10 ohms.Two. Safety regulations for tower cranes GB 5144 - 20068.1.3 tower crane metal structure, track, all electrical equipment metal shell, metal line pipe, safety lighting transformer, low voltage side should be reliable grounding, grounding resistance is not more than 4 ohms.
