Jib Crane Apparatus
Product Code : EL-AMLE-10630
Jib Crane Apparatus (code EL-AMLE-10630) is a force-system model used to study the forces in the jib and tie of a jib crane, where several forces act at a single point. The jib and tie are attached to a vertical metallic rod, a load hanger at their junction puts the tie in tension and the jib in compression, and the forces are shown by integrated spring balances while dial gauges measure deformation.

What Is the Jib Crane Apparatus Used For?
A jib crane carries its load at the point where the jib and the tie meet, and the forces there form a simple concurrent system that can be solved by drawing. The student hangs a load at the junction, reads the bar forces on the spring balances and the deformation on the dial gauges, and then draws a force parallelogram to scale to find the cable, tensile and compressive forces graphically. Comparing measured and drawn values, and repeating with other jib forms set by the adjustable bar and clamp elements, shows how the geometry changes the force in each member.
What to Specify When Ordering
- Quantity — the number of jib crane units required.
Frequently Asked Questions
Which forces are found with the Jib Crane Apparatus?
The resultant cable force, the tensile force in the tie and the compressive force in the jib are determined, both graphically with a force parallelogram and by experiment.
How is the load applied?
A hanger at the junction of the jib and the tie carries the load, which places the upper tie in tension and the lower jib in compression.
How are the forces and deformations read?
Integrated spring balances indicate the forces in the bars, and dial gauges connected to both the jib and the tie measure their deformation under load.
Can the shape of the crane be changed?
Yes. The crane jib is made up of a bar of adjustable length and a chain, fixed to a retaining bar by adjustable clamp elements, so a variety of jib forms can be set up.
What is meant by a central force system?
It is a set of forces lying in one plane and acting through a single point. At the jib head the load, the tie force and the jib force meet in this way, so they must balance.
