If you are a rigger in the industry, you’ll likely have heard of or even attended CM Hoist School. Hosted by Mountain Productions in Wilkes-Barre, PA, Hoist School is a five-day seminar focused on rigging, hoist maintenance, and motor control.  

Flyhouse has been the lead instructor for the rigging seminar for the last two years. This year Flyhouse is represented by Eric, our Director of New Product Development, who has been an instructor at Hoist School for the last seven years. Over the last week, he has shared his vast rigging knowledge with those in attendance.

What were the takeaways from his students?

5 Hoist School "Rigging" Takeaways

1. Amsteel rope whoopie slings are the best.

2. How to correctly build a bridle and get the point right on the mark. 

3. Understanding what the forces are in the bridle. 

4. There are important differences between "V" and "Y" lanyards for fall arrest.

5. It is impossible to calculate how much tension there is for each point on a straight run of truss with more than two points. You can guess! But it won't be right. You need to monitor the load with a load cell or other type of scale.

Posted by Flyhouse on Sep 1, 2017 9:00:00 AM

Have you ever thought about the difference between stop sleeves and compression sleeves? If you're in the rigging industry, they are standard items used on the job. What if you used wire rope that was powder coated? Would that make a difference? Flyhouse tested some scenarios to give you a better sense of what they are capable of doing.

Jay O. Glerum Rigging Master Classes

Posted by Flyhouse on Jun 13, 2017 8:31:13 AM

In the world of theater, especially among those devoted to the craft of stage rigging, one name has always been synonymous with providing the highest level of safety and technical knowledge available: Jay Glerum. Glerum is the author of the Stage Rigging Handbook, an essential how-to guide kept in the bag of every rigger as a reference. After his death in 2014, USITT, in partnership with leading industry vendors, including Chicago Flyhouse, announced the Jay O. Glerum Rigging Master Classes to further the cause of rigging safety in his memory.

In its second year, Flyhouse's Head Trainer and Cruise Ship Division Manager, Ed Leahy, will once again be the Lead Instructor for the entry-level classes. From June 13-14, an entry-level class will take place with a second offering of both entry-level and advanced sessions scheduled for August 14-15.

The entry-level class is designed around venue managers – individuals like music teachers who are asked to manage a theatrical space. The focus is to provide enough information so participants can understand how to effectively manage their space in terms of what kind of work can be done in-house versus what should be done by a professional.

Major topic areas of the entry-level class:

• Basic Physics – why things stay up in the air and why they fall

• Process and Protocol – good practices for running a safe space

• Types of Rigging Systems – an overview of hemp, counterweight, and motorized fly systems

• Rigging Tools and Hardware – understanding why we use what we use, and how to make good choices

• Working at Heights – safety basics for ladders and lifts

• Fall Protection – basics principles

• Basic Maintenance – guidelines for keeping your space in top shape, including inspections
