Calculate Force Compression of Crane with Hoisting Slink

Click For Summary
SUMMARY

The discussion focuses on calculating the force compression of a crane equipped with a hoisting slink and pulley. Participants agree that the addition of the hoisting slink and pulley increases the compression force at hinge A compared to a configuration without these components. The importance of creating a free-body diagram to visualize the forces acting on the crane is emphasized, with the first scenario involving two forces and the second scenario involving three forces. This analytical approach is crucial for accurate force calculations in crane operations.

PREREQUISITES
  • Understanding of basic mechanics and force analysis
  • Familiarity with free-body diagrams
  • Knowledge of crane operation principles
  • Basic understanding of compression forces in structural engineering
NEXT STEPS
  • Study the principles of free-body diagram creation in mechanical systems
  • Research the effects of additional components on force distribution in cranes
  • Learn about the mechanics of hoisting systems and their impact on load forces
  • Explore advanced topics in structural analysis related to compression forces
USEFUL FOR

Engineers, crane operators, and students in mechanical or structural engineering who are involved in analyzing crane mechanics and optimizing load handling processes.

Actually it is a simple one, but the point of view of the force acting in pic attach of some people are different.

The adding weight of hoisting slink blue and the pulley is neglected.

I think the crane with hoisting slink (and pulley in first pic) creating more compression force into hinge A than the one without.

Is my analysis correct?

On problems like these I was told to make a free-body diagram.

Simplify the problem by imagining the lifting boom is vertical and draw a free-body diagram or just imagine it for the two diagrams. In the first case you have two forces and in the second case you have three forces.

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
