Crane Rigging Angles

1 Reply
 

 Model Description This demonstration depicts the importance of rigging angles during crane lift operations on a construction site.  Reducing rigging angles results in a significant amplification of forces in the rigging, potentially leading to failure.  By varying the connection points and sling length, students will be able to calculate the predicted forces and analyze the […]

Excavation and Earthwork Pressure

Leave a reply
 

 Model Description This in-class activity provides students the opportunity to participate in an interactive demonstration to visualize the concepts of soil pressure and potential effects on construction excavation support systems. In this demo, students are able to interact directly with small-scale models to exhibit the concepts of at rest (equilibrium) soil conditions, active soil pressure, […]
