6、 Portal crane is widely used in the port .It has complex structure, most institutions, typical electric loading and unloading machine. And it has the advantage of better performance and unique structure, good versatility.Introduction: Its structure can be divided into two parts: the upper rotating p

7、art and the lower running part.Classification:Divided into three categories according to use:Loading and unloadingShipbuildingconstruction and installation Port ShipyardConstruction siteMechanism LuffingRunningHoistingSlewingHoisting mechanismHoisting mechanism is indispensable part of work, it will

8、 directly affect the work of the whole crane performance. Hoisting mechanism consists of the following components: driving,winding system,braking and auxiliary devices.Luffing mechanismLuffing mechanism is used to change the working range .In the lifting capacity of the maximum amplitude transport g

9、oods between the minimum amplitude in order to expand the scope of the cranes operation. Portal crane with luffing mechanism mainly refers to the role of this , it is joint work with other meshanism to transport cargoes.Slewing mechanismSlewing mechanism is used to support the weight of rotating par

10、ts, and drive non-rotating part relative to the rotating part of the rotary movement to do some work agency. Its role is to make the sling around the center of rotation of the crane do rotary movement in a horizontal plane in order to achieve the purpose of transport goods.Slewing mechanismRunning m

11、achanismIn the crane operation, often require cranes working position can be adjusted to change the place of work, in order to expand the range of operations, improve handling efficiency. Therefore, the cranes are usually equipped with run institutions, functioning organizations mission is to enable
