MATERIAL HANDLING EQUIPMENT6. CranesGeneral characteristics of cranes:• Used to move loads over variable (horizontal <strong>and</strong> vertical) paths within a restricted area• Used when there is insufficient (or intermittent) flow volume such that the use of aconveyor cannot be justified• Provide more flexibility in movement than conveyors• Provide less flexibility in movement than industrial trucks• Loads h<strong>and</strong>led are more varied with respect to their shape <strong>and</strong> weight than those h<strong>and</strong>ledby a conveyor• Most cranes utilize hoists for vertical movement, although manipulators can be used ifprecise positioning of the load is requiredTable 8.

Jib craneHorizontal boom (jib) supported from a stationary verticalsupportHoist can move along the jib <strong>and</strong> can be used for liftingOperates like an arm in a work area, where it can function asa manipulator for positioning tasksJib can also be mounted on the wallArm can rotate up to 360°36
