The Features of Tower Balance Crane​

Tower Balance Crane is referred to as tower cranes, which originated in Western Europe. A rotating crane with a boom mounted on the top of the tower. Large working space, it is mainly used for vertical and horizontal transportation of materials in building construction and installation of building components.



The boom type of the tower balance crane is divided into two types: horizontal and pressure. When the boom is horizontal, the trolley moves along the horizontal boom and the amplitude is balanced. The boom is longer, but the boom has a larger weight. When the boom is a pressure lever type, the luffing mechanism drags the boom to the pitch and the amplitude is not as smooth as the horizontal, but its weight is small.

The lifting weight of the tower balance crane varies with the amplitude. The product of the weight and the amplitude is called the load moment, which is the main technical parameter of this type of crane. Through the slewing mechanism and the slewing bearing, the lifting height of the tower crane is large, and the inertia quality of the slewing and walking is large, so it is necessary to have good speed regulation performance, especially the hoisting mechanism requires light load, fast load, slow speed, and installation. In addition to the use of resistance speed regulation, it is often used to adjust the speed of the eddy current brake, frequency modulation, variable pole, thyristor and electromechanical combination.

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...
