How much weight does Zhengxing tower crane 63 rotary machine weigh

Very large tower crane weighing up to 60 tons.

Panshan Garden Phase I Project Tower Crane Attached Wall Lengthening and Renovation Technology (Shenzhen Yuezhong Group Co., Ltd. **** Huang Kaixue Zip Code: 518040) [Abstract] The center distance of the tower crane A attached wall of this project is up to the longest meter, more than 2 times the standard, in order to ensure the safe use of the tower crane, according to the data provided by the manufacturer, the attached wall rod, the hoop ear plate, the attached wall ear plate is strengthened and designed, and the existing materials are used to transform it.

Keywords] tower crane attached to the wall rod hoop lugs attached to the wall lugs Renovation [text] This project uses two Jianglu brand QTZ80 wall-attached tower cranes, and the arm lengths are 40m and 45m respectively. The specific layout is shown in the figure.

1. Figure 2 (Note: tower crane A is Figure 1, tower crane B is Figure 2). Panshan Garden Phase I Project 0.

00 to the roof water tank, the total height of the tower crane is 135m. Tower crane A, B are 6 times attached to the wall, each attached wall elevation for the tower A: . 9m、+。9m、。18m;Tower crane B: + 9m, + 87.

9m, + see Figure 3 for details. The anchorage of the tower crane A crane attached to the wall 1, the selection of the brace According to Figure 1, because the longest wall rod is the rest, the internal force of the attached brace is f = the factory calculates f according to the plan). A group of tower crane attachment struts is made of two combinations of 16A channel steel, with a 10mm seam in the middle, a 6mm thick steel plate of 60mm*120mm, and a spacing of 300mm welding, see the figure below.

The mechanical properties of the tower crane attachment struts [16a are as follows: Known: nmax(f)=.

8= s[16= In order to prevent the instability and compression buckling of the attached wall rod, the allowable slenderness ratio is [ ]=200, and the stability coefficient is =,lx=,f=215n mm2.

Solution: The cross-sectional area of the attached wall rod is: a nmax = f 283

Check if the voltage is normal.

If the slewing brake of the tower collapses and the crane fails, first determine whether the brake contactor is intact in the regiment. If it's good, then it's a matter of controlling the line. It is recommended to check whether the low-voltage transformer has an output and whether the silicon rectifier bridge has a DC output.

Troubleshooting is carried out step by step.

To put it succinctly, Vanda.

The domestic quality is better than Zoomlion, Guangxi Construction Machinery, Sichuan Construction, Chongqing Qingjiang.

The actual use of Zoomlion's tower crane is more stable, and the material is more solid.
