Do you know the Regulation of Tower Crane Lifting Height?

As a 10 T Top kit Tower Crane Wholesale, share with you.
Lifting height is also called hook height, which is the vertical distance from the concrete foundation surface of the tower crane (or the top surface of the walking track) to the hook. For trolley cranes, the maximum lifting height is immutable. For pitch cranes, the lifting height varies with different amplitudes. At the minimum amplitude, the lifting height can be several dozens higher than the tower tip meters, so the tower crane with pitch amplitude has an advantage in lifting height.

Tower crane lifting height includes two parameters, one is the lifting height when the tower crane is installed at a free height, and the other is the maximum lifting height when the tower crane is attached. The tower crane does not need to be attached when the free height is installed. The general tower crane It can reach 40 meters, which can meet the needs of buildings below small high-rises.
In order to prevent tower crane hooks from rising too high and causing damage to the equipment, a safety limiter is installed on each tower crane. When the hook is raised to 1-2 meters away from the boom, the lifting power is automatically cut off to prevent the hook. 
Working speed
The working speed of the tower crane includes: lifting speed, slewing speed, and luffing speed. In the lifting operation, the lifting speed is the most important parameter, especially in high-rise buildings. Increasing the lifting speed can improve the work efficiency. At the same time, slow speed is required when the lifting object is in place. Therefore, the wide range of lifting speed is lifting. Superior performance.
The lifting speed is not only related to the lifting mechanism, but also to the magnification of the hook pulley block. The 2 rope is twice as fast as the 4 rope, and the single rope is twice as fast as the 2 rope.
In hoisting operations, the speeds of turning and luffing are not required to be too fast, but they must be able to start and brake smoothly and achieve stepless speed regulation. Frequency conversion control is ideal.
Tail size, component weight and outer porch size.
The tail dimension of the lower swing crane is the maximum turning radius from the turning center to the tail of the turntable (including the weight), and the tail dimension of the upper swing crane is the maximum turning radius from the turning centerline to the tail of the balance arm (including the weight). The size of the tail of the tower crane is an important parameter that affects the installation and disassembly of the tower crane and the turning operation.

Crane History

图片
As a  Luffing Tower Crane Supplier , let's share with you the history of the crane. In 10 BC, the ancient Roman architect Vitruvius described a lifting device in his architectural manual. The machine has a mast with a pulley on the top of the pole, the position of the mast is fixed by the pulling rope, and the cable passing through the pulley is pulled by the winch to lift the heavy object. Some overweight machines can use two masts to form a herringbone shape, moving the lifting object laterally, but the amplitude is small and the operation is very difficult. In the 15th century, Italy invented  Luffing jib Tower Cranes  to solve this problem. The crane has a sloping cantilever with a pulley on the top of the arm that can be lifted and rotated. However, until the 18th century, all kinds of lifting appliances used by human beings were powered by human and animal power, and they were limited in terms of lifting the weight, the scope of use and work efficiency. In th...
