A jib crane installation can be a game-changer for your workspace, but it's essential to do it right to ensure safety and efficiency.
First, identify the load capacity of your crane, which is typically determined by the weight of the heaviest object you plan to lift.
To calculate the load capacity, consider the weight of the crane itself, the weight of the load, and any additional factors such as wind or seismic loads.
A well-planned installation will also involve determining the crane's span and height, taking into account the available space and any obstacles in the area.
Design and Installation
To ensure a safe and efficient jib crane installation, it's crucial to pay attention to a few key details. Proper installation is essential to avoid accidents and construction delays.
The strength of the concrete is critical when installing a cantilever crane. Don't start installation if the concrete is not fully set, as it may compromise the load-bearing capacity of the crane.
A flat and debris-free floor is also essential for a stable installation. If the floor is paved with tiles, add a suitable layer of cloth to increase friction with the ground.
Foundationless
Foundationless jib cranes are a great option for facilities where speed and flexibility are key. They can be installed almost anywhere as long as the area meets the manufacturer's requirements.
These cranes are slab-mounted and bolted to 6" reinforced concrete, eliminating the need for a special poured foundation. This means installation can be done faster, with no waiting for concrete to cure.
Typically, foundationless jib cranes can accommodate a range of specifications. Here are some of the key details:
- Spans of 9-16' are common
- Capacities up to 1,000 lbs. are possible
- 360° rotation is standard
- Boom heights up to 20' are achievable
While they may have a lower capacity than traditional freestanding jib cranes, foundationless jibs offer a cost-effective and portable solution for many applications.
Wall Bracket
When designing a wall bracket for a jib crane, it's essential to consider the specifications of the crane. Wall bracket jib cranes are versatile and can be used in various settings, including bays, along walls or columns, and as supplements to an overhead crane or monorail system.
They're perfect for workspaces where headroom is at a premium. These jibs utilize I-beam boom assemblies for heavier capacities and longer spans.

Precautions for Installation
Pillar jib cranes are a convenient and efficient option for short-distance lifting operations, but their installation requires careful attention to detail.
Ensure the strength of the concrete is high before installing the cantilever crane, as weak concrete can lead to accidents such as collapse and overturning.
A flat and debris-free floor is essential for proper installation, and if the floor is paved with tiles, a suitable layer of cloth must be added to increase friction with the ground.
Check the verticality of the column from different directions to ensure it's installed correctly.
Don't use a common hook wrench to tighten the nut fixing the screw cylinder, as it may not be strong enough - instead, use a round pipe extension for added leverage.
Always check if the nut is loose during lifting to avoid accidents.
The rotating arm on the column should be placed at an appropriate height to maintain the load-bearing capacity of the column, ideally within an angle of 45 degrees between the inclined arm and the column.

Before Buying
Before buying a jib crane, it's essential to consider the specific purposes it will fulfill and the lifting requirements of your workspace. The exact limitations of your workspace will determine what kind of jib crane you need to use.
The dimensions and weight of the load you require moving will impact what type of jib crane is most suited to your work area. You'll need to know the maximum load weight to make an informed decision.
Here are the maximum load weights for different types of jib cranes:
The available space in the work area is also crucial to consider, as you'll need to allow for free rotation of the boom. The approximate span of each jib crane is:
- Free-standing jib crane – up to 20’
- Mast-type jib crane – 10-20’
- Wall-mounted jib crane – 8-20’
Understanding these limitations will help you choose the right jib crane for your specific needs and ensure a safe and efficient operation.
Where Do You Need to Move It?
When you're deciding where to move it, consider the type of load and the space it needs to reach. All jib cranes can rotate up to 360 degrees, making them ideal for maneuvering loads around corners or between workstations.
If you need to move the load in a tight space, a wall-mounted jib crane might be too limited, rotating between 180 and 200 degrees. Articulated jib cranes are a better choice for maximum maneuvering capacity.
Articulating jib systems can be mounted in various ways, including to the floor, wall, ceiling, or a bridge or track system. This flexibility provides more precise load positioning in tight spaces.
The boom span of an articulating jib system is limited to a total of 16 feet, so keep that in mind when planning your move.
