What is a crane?
Bridge Crane, sometimes called a crane in the upper, is a type of crane with a movable bridge that runs on elevated rays hanging over their heads. This allows you to move the load in three axes to and any point in the crane operating area. In addition to the bridge, the bridge system includes a crane and a jack that can move along the entire length of the bridge, and rays known as the track over which the bridge moves back and forth. The cloam moves from side to side over the bridge, perpendicular to the direction of the bridge movement, which entails a jack that can be lifted and reduced from the floor to load at different heights. Two main categories are top versus subject to bridge cranes and bridge cranes with one carrier. This allows four general configurations: top-running with one bearer, top-R double girderunning, single-girder insufficiently running and double player inadequately running bridge.
Top Run and under Running isAh as the bridge moves along the track. The highest cross -country crane is the one in which the bridge runs over the tops of the rays of the raised track, while the lack of cross -country bridge has a bridge that leads under the track. If the heavier loads are to be moved, the highest cross -country cranes are usually chosen. If the headroom in the work area is a problem, it is also the highest configuration also usually preferred configuration, because the jack does not print as deep below the bridge as if it were in insufficient configuration.
Single beam and double beam refer to the number of bridge beams supporting trolley and jack that runs along the bridge. The advantage of the system for the one -wise amount of material needed to create it, lower transport costs resulting from its lighter weight and faster installation of the system. The double player system usually allows a higher lifting height, because the jack is located between the bridge beams rather than below them, so the vertical operating space remains open.
The crane of the bridge in the upper bridge, with its landing track suspended from the floor, can be selected through a forklift to move the load around the warehouse or factory floor when the floor space is scarce. On the other hand, forklifts not only take up valuable floor space, but can also serve as obstacles around which the load must be maneuver. Bridge cranes also often offer more freight capacity and lifting height than fork.
General security measures for the operation of the bridge include delay in lifting, reducing or movement of load, while there is a person on it and avoiding the movement of the load over a person. The side strokes in which the horizontal force of the apply on the side of the load suspended from the crane is usually discouraged. In rare cases where they are carried out, they usually occur only in highly controlled circumstances. Numerous detailed safety standards focused on design, installation, operation, inspection, maintenance and repairs are submitted by various government agencies andprofessional companies.
