venues and rigging

Rigging and venues

The job of the entertainment rigger is to suspend objects such as lighting, sound, scenery and even performers at specific locations above the stage.


In order to avoid catastrophic failures, we must calculate forces such as static and dynamic loads.  


The weight of our rigging is not always straight down, the resultant forces must be calculated so that we can adhere to the structural design of our architecture and equipment.


The height, weight, size and position of each object has a direct effect on how we do our math.


Doing our calculation up front is our first line of defense against have a potential failure.

Production rigging: math, physics and a lot more.

Rigging: A quick introduction.

A quick description of concert rigging and the S.T.E.A.M. subjects behind it.

Rigging: A quick illustration.

Rigging: A quick introduction.

Rigging: A quick introduction.

This video gives us a quick visual look at overall rigging and the forces and concerns behind suspending weight.

Resulting Force Introduction.

Rigging: A quick introduction.

Pythagorean's Theorem in rigging.

In order to make sure we do not overload our venue, we must understand forces.  This video introduces the concept of resulting force and how it applies to rigging.

Pythagorean's Theorem in rigging.

Calculating weight on a truss for safety.

Pythagorean's Theorem in rigging.

Here we utilize Pythagorean's Theorem to help us calculate the distance between 2 points.  This distance helps us to utilize the correct length of materials for our application.

Asymmetrical Bridle Calculation

Calculating weight on a truss for safety.

Calculating weight on a truss for safety.

The previous video demonstrated calculating a bridle for a symmetrical application.  This video demonstrates Pythagorean's Theorem to calculate a bridle that is asymmetrical.

Calculating weight on a truss for safety.

Calculating weight on a truss for safety.

Calculating weight on a truss for safety.

This video demonstrates how force and weight need to be calculated for safety and equipment reasons.  Here, we calculate the load/weight of lighting placed upon our truss.

Calculating truss weight and total load.

Calculating truss weight and total load.

Calculating truss weight and total load.

This video continues the calculation of weight.  Here we learn how to calculate truss loads and then the initial full load on our motors.

Calculating an offset weight. Part 1

Calculating truss weight and total load.

Calculating truss weight and total load.

In this video, our load is not uniform or symmetrical.  As a result, the tension on each motor will be different.  This is the first motor tension calculation.

Calculating an offset weight. Part 2

Calculating truss weight and total load.

Calculating an offset weight. Part 2

In this video, we continue our asymmetrical tension calculation by calculating the tension on our 2nd motor.
