When one talks about jib cranes, it reminds of the most commonly used jib crane which is the free-standing jib crane. This jib crane when kept in open, can serve multiple purposes and companies. It is highly preferred for outdoor activities like loading docks.

Let’s discuss some really interesting facts about jib crane that you should you are considering to plant one at a site.

Interesting Facts about Free Standing Jib Crane

1. Capacity
These free standing jib cranes are capable of carrying heavy materials from 220kgs to 4500kgs. Although jib crane is used to lift heavy objects across multiple industries, the crane needs to be inspected thoroughly prior to general use.

2. Coverage
The free-standing jib cranes are stationary but can get the work done in the coverage of 360 degrees, from where they are installed. These kind of cranes can also span from 8ft to 20ft. The boom can rotate freely using heavy duty roller bearings. This offers the jib crane a circular coverage.

3. Jib Removal
In case someone wishes to remove the jib, sleeve option is installed at the foundation of these cranes. This makes it easier for the person to separate jib from the free-standing jib cranes.

4. Operation and Life
The union assemblies and accurate tapered ball bearing in the top pivot play a vital role. They result in smooth operation and longer service and life of the crane. Also, the crane manufacturers in Ahmedabad give a warranty for a longer period as compared to others.

5. Positions Load Accurately
Although these cranes are used to lift heavy objects, they still need support when it comes to positioning the loads in the exact place. Hence, a fully supportive triangular base plate gusset is used to position the loads accurately. This increases the work efficiency of the machine.

6. Separate Installation
Boom connection in the free-standing jib cranes allows separate installation. When it is installed very close to the underside of the lower ceiling obstruction, it provides the maximum lift of the hoist.

Designs of the Free Standing Jib Crane

When it comes to mounting and installing, there are mainly three designs of the free-standing jib crane.

Sleeve-insert mounted

In the sleeve-insert mounted design, a sleeve is attached to a steel plate, which is later used to position the sleeve. This is done by anchoring the sleeve to a first-pour concrete footing. The next pour supports the envelope and this is followed by the mast being inserted into the sleeve. It is leveled and then attached in the same place. One of the major advantages of this design is that it allows the relocation of the jib system without damaging the mast.

Base-plate mounted

Base-plate mounted design is the easy and popularly used design. In this, the mast is secured by bolting the base-plate onto the concrete foundation. This is then followed by the strengthening of the mast with gussets.

Foundation-insert mounted

These foundation-insert mounted designs have attached steel plates at the bottom of the mast. This mast is anchored during the first pour of the concrete footing. The second pour thus supports the mast, which eliminates the need for gussets.

Free-standing jib cranes are more appealing because of the scope of getting the work done, higher capacities and majorly the 360-degree coverage. Apart from being a bit expensive, there is no such disadvantage of free-standing jib cranes.
