How to calculate the counterweight and lifting weight of a tower crane?

The counterweight and lifting weight of a tower crane can be calculated by the maximum horizontal distance. The so-called maximum horizontal distance refers to the horizontal distance in which the crane boom extends into the direction of the lifting object under the premise of normal lifting operations. In general, it is the horizontal distance from the lower shaft of the crane boom to the hook. The maximum horizontal distance Smax can be determined by the actual situation of the construction site. How to repair the crane station and the basic position of the equipment, the position of the container, etc.

How to repair the tower base loose?

The method of repairing the tower base loose depends on the specific situation and the degree of damage. The following are some possible repair methods: 1. Clean-up: Remove weeds and dirt from the vicinity of Taquisone and keep the area clean and tidy. 2. Patch Repair: For cracks or damaged parts, use mortar or special concrete repair materials to repair. 3. Reinforcement Structure: If the structure of Taquisone is found to be loose or not firm, materials such as brackets or steel bars can be used to reinforce Taquisone. 4. Surface Treatment: Taquisone can be re-painted, and waterproof coatings or coatings with strong weather resistance can be used to protect the outer surface. 5. Preventive Measures: In order to prevent Taquisone from being damaged again, it is possible to consider building a drainage system to ensure that the water flow is away from Taquisone, and regular inspections and maintenance can be carried out. Please note that before any repair, it is best to consult the advice of professionals and take appropriate measures according to the actual situation.

Calculation of the lifting weight of the tower crane?

Answer: The rated lifting weight of the tower crane * The distance between the trolley and the center of the tower body = the rated lifting moment.

The torque generated by the balance arm of a general tower crane is greater than the maximum lifting moment. The tower crane itself is a steel structure with an unbalanced lifting arm and the balance arm. This unbalanced part is balanced by the foundation. Since the torque generated by the balance arm is large, that is to say, in the case of no lifting objects, the torque generated by the maximum wind load is the overturning moment of the tower crane

How about the maximum lifting weight of the tower crane?

Tower cranes lift the most weight at the smallest amplitude, and the lifting weight decreases accordingly as the amplitude increases. Therefore, there are rated lifting weights at various amplitudes. Different amplitudes and corresponding lifting weights are connected to draw a performance graph of the crane.

Rated lifting weight * The distance between the trolley and the center of the tower body = the rated lifting moment.

The torque generated by the balance arm of a general tower crane is greater than the maximum lifting moment. The tower crane itself is a steel structure with an unbalanced lifting arm and balance arm. This unbalanced part is balanced by the foundation.

Since the moment generated by the balance arm is large, that is to say, without lifting objects, the moment generated by the maximum wind load is the overturning moment of the tower crane.

When checking the rectangular foundation, the bending moment of the foundation is the largest in the diagonal direction, so as to reinforce.

The maximum lifting moment is obtained without considering the wind load. Theoretically, it is very dangerous to achieve.
