L68B1 Mast Section the distance between the tower and the building, and the type selection related to the distance between the building
The distance between the tower and the building, and the choice of the tower crane type is related to the distance from the building? For example, the principle QTZ 40 tower crane, placed him at the distance from the building?
L68B1 Mast Section L68B1 mast section is the best in this field
For a general tower crane, the climbing frame is 1.7 meters wide on one side, and the outer frame range is generally: 200 + width 1000 + exposed horizontal rod 100 = 1.3 meters, totaling 3.0 meters. If the operating room is on the side of the building, Add 0.6 meters, a total of 3.6 meters, Consider the safety range of 200, it is 3.8 meters.
Specifically depending on the type of tower crane. If the length of the short wall needs to be reduced, under the conditions of satisfying the attached wall, the width of the outer frame can be reduced, and the operating engine room can be moved to a non-wall side when the tower is mounted, which should be shortened to 3.0. The base of the tower crane needs to be connected with the structural foundation. As a whole.
According to the construction site how to choose the appropriate tower crane model?

When doing construction organization design, how to select tower crane model correctly? This can refer to your project quantity list or construction organization design. You need to consider the following:
1, plane, the plane here refers to the scope of lifting, construction plan, if the podium is a common tower hanging, it needs to be in the middle of the group building, but consider the attached wall erection and lifting range.
2, the current design is a machine on the first floor, the tower crane is set in the floor plan, the middle of the building on one side. At this point, consider the removal of the tower crane. For example, if the building plane is 40 * 50 meters Square, then it is in the middle of the 50, that is, 25 meters, except for the consideration of erection. Of course, this erection is relatively conventional, if the architectural design is not symmetrical. There are more objects that may be heavy on one side, so the location of the tower mount is more inclined to the one with more weights. This needs to be seen according to your organizational design and engineering inventory. Combine the plane and the facade. We 'll be able to pinpoint the location.
3, lifting radius and weight, in the scope of the operation, also need to consider, as in the example of 2 above, the building plane is 40 * 50 meters Square, then in the middle of 50, that is, 25 meters in addition to consideration of erection, Then the relatively long one is satisfied. At this time, the 40-meter side becomes the longest party. At this time, consider that the tower crane should establish the first condition: the arm length should be met by 40 meters. Select the tower crane to pay attention: use the short arm as much as possible., otherwise the longer the arm, The higher the price! Remember, this is something that many experienced project managers will take into account, as well as the fact that the attached walls are kept as low as possible under secure conditions. There are many kinds of Tower cranes with a length of 40 meters. According to this condition, you can select some tower cranes.
