How to calculate the efficiency of tower crane with two towers and three floors

The calculation method of tower crane efficiency on the third floor of twin towers needs to calculate tower crane efficiency. Usually, many factors need to be considered, including the lifting capacity, working radius, working height and working period of the crane. The calculation method is as follows:

1. lifting capacity: firstly, determine the rated lifting capacity of the tower crane, that is, the maximum weight it can bear. Lifting capacity is usually expressed by the maximum load (ton) of lifting weight.

2. Working radius: determine the working radius of the tower crane, that is, the horizontal distance (m) from the reference point of the tower crane to the spreader. The working radius determines the horizontal coverage of tower crane.

3. Working height: determine the working height of the tower crane, that is, the vertical height (m) from the reference point of the tower crane to the spreader. The working height determines the vertical range of tower crane.

4. Work cycle: determine the work cycle of the tower crane, that is, the time (minutes) required to complete a lifting cycle. The work cycle includes the time for hanging objects, moving and placing them.

5. Calculation of efficacy: The efficacy of tower crane can be calculated by the following formula: efficacy = (lifting capacity× working radius)/(working period× working height). According to the above formula, the specific numerical value can be substituted into the calculation, so as to get the efficiency value of the tower crane. The main function of tower crane is to lift materials, which can be transported horizontally or vertically. Hanging materials include steel bars, wooden beams, concrete, steel pipes, etc.
