How to Counteract Weight in Fabric Shade Structures

One of the greatest advantages of fabric shade structures—especially in temporary applications—is their low overall weight.  This makes them easier to assemble, quicker to take down, and simpler to transport. Still, weight can be a problem.

Maximum Loads in Stage Rigging: How Hardware and Ropes Work Together

The stage rigging basics have changed significantly since the old hemp systems of the “Golden Age of Sail” (1850-1900).  For starters, riggers have far more choice of materials in hardware and soft goods today.  Hemp, wood, leather, canvas, and metal have given way to thermoplastics and synthetic...

Using Soft-Attach Blocks and Friction Rings with Industrial Rope

The advanced synthetic fibers in modern industrial rope have given soft-attach pulley blocks several functional advantages over those fastened with traditional hardware.  Whereas metal hardware is inflexible, heavy, and may present a limited range of motion, a soft loop or lashed rope is much more...

5 Advantages of a High Safety Factor For Industrial Rigging Equipment

Most industries prefer a 10:1 safety factor of breaking load to expected load for industrial rigging equipment.  In other words, if most tasks in general use will involve burdens of around 100 lb on the equipment, it should be able to support a maximum load of 1,000 lb before breaking.

How to Create Ideal Tension in Shading Systems

Tension in a shading system is a complex balancing act.  It’s both critical to the stability of the structure and also a significant source of risk when mishandled.   Too little tension, and the structure risks damage from wind or pooling water. Too much, and the attachment points may break,...

How to Fight UV Degradation in Industrial Pulley Systems

Outdoor industrial pulley systems are exposed to intense ultraviolet radiation throughout their service life. Without proper protective measures, the absorption of these rays will cause UV degradation (cracking and disintegration over time) to natural and synthetic polymers alike.

Truss Rigging Hardware for the Entertainment Industry

Truss rigging systems are designed to bear incredible loads across vast spaces.  The typical box, triangle, and ladder designs provide more stability and support than single pipes while also giving you the flexibility to hang numerous fixtures wherever necessary.

Why Use Marine-Grade Materials For Entertainment Rigging?

Entertainment rigging is comprised of two main branches, both of which benefit from marine-grade materials: theatrical rigging and arena rigging. Both call for the same rigging skills, but they differ in the conditions under which the equipment must operate.

Form, Function, and Uses of Lashing Blocks

When a pulley block relies on soft goods (rope or straps) to secure it between its load and an anchor point, rather than hard fasteners, it is a lashing block.  Lashing blocks provide a versatile setup that can be used for single pulleys or whole block and tackle pulley systems to lighten the...

Stainless Steel Grades For Outdoor Industrial Use

Stainless steel is highly versatile (with dozens of specialized grades), durable, and extraordinarily resistant to corrosion.  Chromium is the element that makes a steel “stainless”: it can polish to a stunning shine and won’t rust as easily as carbon or galvanized steel.

Different Types of Blocks, Pulleys, and Ropes and How They Work Together

The many possible combinations of pulleys, blocks, ropes, and other hardware for your system can make the process of selecting and assembling the ideal equipment daunting, but that doesn’t mean it’s any less important.

Is Synthetic Rope Really 15 Times Stronger than Steel Cable?

The appeal of steel wire ropes and cables lies in their durability, resistance to abrasion, and the ability to withstand greater loads without failure when compared traditional organic fiber ropes.  Stainless steel can even mitigate the risks of rust and corrosion that are a major weakness of metal...

Solid Bearing vs Ball Bearing Pulley Blocks

Load type is a major consideration that affects which block to use in your pulley system. Static loads are stationary, applying their weight consistently to the same area of the bearing, but dynamic loads are often in motion and require a bearing that can evenly distribute that force.

Types of Pulley Systems: Block and Tackle Rigging at Work

Through the centuries the block and tackle system has been optimized to meet the evolving needs of the professionals who use it. Today, block and tackle systems power innumerable daily tasks from recreational yachting to helicopter rescues and more. Here’s a closer look at how the system works and...
