Very often the project engineer encounters the typical “low-headroom problem” with jib cranes: an overhead obstruction restricts the height of a jib crane, but a load has to be lifted to a maximum height, as in this illustration:
The Solution to Low Headroom Lifts
When there is very little headroom, what’s needed is a very slender boom that just passes under the obstruction but maximizes the height of the hoist. This can be done with a steel I-beam, but then the operator is faced with the task of pulling the heavy I-beam back and forth all day as he or she works.
What’s needed is a lightweight, low-headroom solution.
We have just applied for a patent for a low-headroom, low weight jib crane, shown here:
How Our Low Headroom Jib Cranes Work
The low-headroom jib offers a very slender aluminum boom that is supported by a steel flatbar on top that runs some fraction of the length of the boom.
This is an example of a low-headroom 250-kg jib crane, this time with 2 aluminum rails, in a rail-on-rail configuration.
Lifting Heavier Loads with a Smaller Jib Crane
The steel flatbar withstands an extreme amount of tension while carrying the load. The aluminum rail experiences significant compression at the bottom of the rail where it contacts the steel upright:
Jib Crane Lifting Capacities
The Low-Headroom configuration is offered in 100kg, 250kg, and 500kg capacities.
Lift Efficiently, Even with Overhead Obstructions
The low-headroom G-Rail jib crane is a very low-weight configuration that offers a low profile that maximizes the amount of lift. This is a patent-pending solution that is not commercially available anywhere else.
