the lifting of the tower CRANE larger and smaller
Q: Why does the lifting of the tower have a larger lifting range and a smaller lifting weight?
Answer:
The lifting amplitude of the tower crane is inversely proportional to the lifting weight: the larger the lifting amplitude, the smaller the lifting weight. Similar to the principle of leverage, when the torque at both ends of the lever fulcrum is equal to the product of the force at both ends, the lever can be balanced, and the weight of the weight mass and the length of the balance arm in the tower crane can not be changed. Then when the car goes forward, his torque will become larger. If he wants to balance the two ends, the force will be reduced accordingly, and vice versa.
How far should the building tower be from the surrounding houses?
Q: How far should the tower be from the surrounding houses?
Answer:
Ensure that the horizontal and vertical safety distance between the tower crane and adjacent buildings, structures and other facilities is greater than 2M, and that the horizontal and vertical safety clearance of the hanging during work must also be greater than 2M.
In other words, no matter how far the tower is from your home, as long as his rotation is not more than two meters from your home horizontal or vertical distance, it is in accordance with national security regulations? More precisely, the length of the tower can not exceed 23 meters.
