What is a crane?

Crane is a mechanism that uses a simple set of lifting and lowering objects the machine and to move in the horizontal direction. They are always equipped with at least one winding; cables, ropes or chains; and pulleys. Both pulleys and winder are a form of a pulley.


Cranes may use a combination of simple, to get the advantage and lifting machines, mechanical objects. A first lever which is used in the balance-style crane. Girder overhead crane is balanced on a fulcrum that allows you to lift heavy objects with fewer forces. The second style jib crane, which uses pulleys to achieve a mechanical advantage (but note that all cranes use pulleys - in this case, the pulleys are the main source of mechanical advantage). A third method of the crane can lift the objects by a hydraulic cylinder, either directly or by feeding or balance the antenna.

Horizontal Movement

The horizontal movement of the crane can be done one of two ways. First, to install all the device on a rotating axis, and a swing arm or around a supporting beam. This is very common in mobile cranes and derricks used in some building. The second method is to roll the load back and forth on rails along the pen itself. This is very common in stationary cranes in ports and railway stations.


A final consideration in the operation of cranes is stability. The crane is stable when the sum of all movements on the basis of zero. In practice this means that the size of the nominal load the tap must be less than what would be necessary to tilt the valve. In the United States, the mobile crane can pick up only 85 percent of what it would take to tip the crane bowl. This stock should take into account the potential of the mobile crane happens to sit instability.
