UNDERSTANDING JIB CRANES: THE INDUSTRIAL POWERHOUSE

Jib Cranes are among the most predominant types of lifting machinery in the modern industrial world. With deep roots in the construction of ancient civilizations of the pre-common era the jib crane has remained a relevant and necessary pillar in manufacturing for thousands of years.

A jib crane is a mounted crane suitable for workstation applications, it has rotational and often articulating capabilities, and is fitted with a hoist that moves up and down a horizontal boom. The result of its capabilities is a workstation lifting device with complete versatility within a range of 180-360 degrees about the mount.

JIB CRANE STYLES & TYPES

The jib crane itself comes in many different styles, the style that suits your needs depends largely on the application requirements, which can include, but are not limited to: load capacity, lift environment, boom span, jib boom outreach, installation, hook reach, rotation, articulation, height under the boom, and any add-on accessories or special requirements, which will all factor in to the overall cost of the crane.

To make the decision easier most manufacturers and suppliers of jib cranes offer guides on choosing the jib style within their product line that suits your individual lifting requirements. It is important to consult an inside product expert during the information gathering stages as some level of customization will almost certainly be required. An on-site consultation may be required for more complex applications.

The name of each jib crane style varies by manufacturer, so let’s instead take a deeper look at each basic jib crane type, which remains relatively constant across the industry.

The most standard jib crane types are: wall mounted, wall-travelling, floor mounted / freestanding, and floor mounted foundationless.

WALL-MOUNTED JIB CRANES

Wall mounted jib cranes can be installed on reinforced walls, steel columns and monotonic poured concrete columns and walls. These jib cranes provide high lift capacity and optimize use of space in the facility; however, jib rotation is limited by the jib mount position.

WALL TRAVELLING JIB CRANES

Wall travelling jib cranes are the hybrid of a jib crane and overhead crane, this is because they are able to travel the horizontal span of a workstation or facility via pre-installed runway beams. They offer the same lift capacity as their wall mounted alternative, but with the benefit of increased coverage.

 

FREESTANDING JIB CRANES

Free standing jib cranes offer the highest lift capacity of any jib crane, this is because a poured concrete foundation and anchor bolt set are used to secure the mount. Free from obstruction, these jib cranes have full 360 degree rotation within a fixed position.

FOUNDATIONLESS JIB CRANES

The same general design as the freestanding jib crane the foundationaless jib crane is equipped with a direct mount base plate to eliminate the need for the costly design and construction of a secure concrete foundation, for lift capacities of up to 2 tons.
