Crane Classification and Selection Tips

You must know that crane is a kind machinery which work circularly and move intermittently. One working cycle includes load handling device lift goods, move horizontally to the named place unloading goods, and then move reversely making the load handling device to the home position so that the next cycle begins.

According to the different crane structure, there are some following classifications:

Light and small cranes

The light and small cranes have such advantages as compact structure, handiness, simple movement and working range projection focusing on point and line. Light and small cranes generally have one mechanism and make heavy weights singular lifting movement.ND European Electric Hoist

Overhead crane

The features of overhead crane is to make heavy weights on the hook or other handling device lift vertically or move horizontally. Overhead cranes include lifting mechanism, crane mechanism, trolley mechanism, through which mechanism heavy weights can be lifted and carried in the square space. Overhead cranes, gantry cranes, loading bridge, metallurgical bridge crane belong to this kind.

Jib cranes

The features of jib cranes are almost same. Jib cranes include lifting mechanism, lubing mechanism, rotary mechanism, through the cooperation of which heavy weights can be lifted and carried in the square space. Jib cranes mostly are set on the vehicles or other transportation tools, which forms moving arm frame rotary cranes.Pillar jib crane -1 ton

Electric hoist

The feature of lifter is that heavy weights or handling devices can only lift along with the guide track. Though the lifter has one lifting mechanism, there are many affiliated mechanisms so it can be as one category which includes elevator, goods elevator and ship lift, etc. Besides this, there are many classifying methods.
