Jib cranes are a subset of cranes that have a jib or boom attached to support a moveable hoist.
Jib cranes are some of the most versatile types of cranes, supporting a variety of capabilities and design options. Typically, industrial jib cranes are used in applications where a lifting solution is needed for operation in a small area or within a large industrial facility that has limited space available.
Compared to other types of cranes, jib cranes are simple to operate, offer more ergonomic lifting capabilities, and require less maintenance because they have fewer operational components.
Industrial jib cranes come in a variety of options and at J.Herbert Corporation, we can supply you with the exact jib crane you need for your material handling application.
A Simple and Easy Guide to Assist You
A jib crane will increase workflow production by improving material handling efficiency. Giving consideration to the following parameters will help you correctly specify the jib crane required for your application.
What is the maximum weight of the load to be lifted? (Generally, the lifting capacity of your jib crane will always be higher than its weight)
2. Boom Rotation
Free standing jib cranes offer up to 360° rotation and wall mounted types offer up to 180° rotation.
3. Jib Boom Outreach
The distance measured from the boom pivot point and usually stated in the following terms:
Boom span – the distance out to the boom tip
Hook reach – the distance to the farthest lifting point
4. Jib Crane Height
The distance measured from the floor and usually stated in the following terms:
Overall height – the distance to its highest point
Height under boom – which is self-explanatory
5. Under Boom Height
Distance from the floor to the underside of the boom, which will determine the type of hoist required.
Free standing jib cranes must be erected on a poured concrete foundation or onto a substantially thick, reinforced concrete slab.
Wall mounted jib cranes can be installed on many types of steel columns such as a wide flange beam or hollow structural tubing or even monolithic poured concrete columns and walls.
UNDERSTANDING JIB CRANES
A jib or boom crane is made of a vertical support and horizontal main lifting arm “boom”. The horizontal post or beam can connect to a wall or floor mounting system. The boom arm or horizontal post supports the hoist mechanism.
Jib Cranes lift and transport materials in full circles (360 degrees) or semi-circles (200 degrees) around their support structure. These jib cranes can also be used to transfer materials to adjacent workstations. Hoists, manipulators, balancers or other below the hook devices can be installed on the jibs’ booms. Jib cranes have three directions of movement, rotational around the axis, traversing (trolley movement along the jib) and vertical (hoist up / down motion). Jib cranes can be configured to have any combination of these motions be either motorized or push / manual.
