Bridge Cranes have 2 runways, a bridge and a hoist. Since the bridge is continuously moving, normally its weight is minimized by using light steel or aluminum shapes.
The rails shown are enclosed track, which use nylon wheels riding on steel for extremely low friction.
Bridge Cranes can be floor mounted, as shown, or hung from ceiling trusses
Rating: Most operator-friendly crane type for light loads |

Articulated Jib Cranes have no enclosed track, but relies on the bending of the arm for X-Y movement.
Articulated jibs are generally easier to use than straight jibs, and they can work around columns and machines
Rating: Moderately operator-friendly, moderate cost |

Jib Cranes have a single enclosed-track boom that pivots about a central mast. Normally they are floor- mounted, but they can also be attached to a wall or the side of a machine.
Floor-mounted jibs may require a foundation depending on the load and the reach.
Rating: Lowest cost crane style |

Slide-Column Crane lifts completed engines using hooks. The slide column is extremely useful in eliminating the swinging that results when tractor drives are used with heavy loads.
The slide column crane is a rigid column that will not swing like a hoist chain does.
For example, when "North" tractor is activated a typical hoist would begin swinging the load. The slide-column crane eliminates the swing and offers exceptionally smooth control.
A slide column crane can also support offset loads, such as picking up a load from an overhead conveyor.
Rating: For heavy loads, is the most operator-friendly crane type |
