Snap Hook vs. Carabiner: Which Quick-Release Shackles Do I Need?

Snap hooks and carabiners (also called carbine hooks) are both mainstay quick-release shackles for the industrial sector.  They don’t even look all that different, in some cases. So what’s the difference? Actually, there are numerous—and significant—differences in how they’re used.

Ropes Are Strong, But This Heavy-Duty Pulley Block Hangs With the Best

There’s a problem in rigging equipment: modern synthetic fiber ropes are almost unbelievably strong. Advanced high-modulus polyethylene (HMPE) fiber ropes like Dyneema® have 15 times the breaking strength of steel (pound-for-pound) at only 15% of a steel cable’s weight (at the same diameter).

An Industrial Umbrella Shade Must Perform Wet or Dry, Rain or Shine

Cantilevered sun shades, freestanding industrial umbrellas, and other permanent outdoor shade structures keep us comfortable in the heat.  A lot of focus is naturally given to the UV resistance of their components, but what’s often lost in translation when we call such permanent structures “sun...

Safe Working Load vs. Breaking Strength for Lashing Blocks & Loops

Soft attachment blocks provide a number of unique advantages over mechanically fastened pulleys.  The foremost is versatility. Lashing blocks can be secured in diverse locations, without hardware or metal fasteners—just a rope loop.

Weight and Friction in Theatre Rigging: How Pulleys Conquer Both

Theatre rigging professionals are faced with a paradox. Unlike most rigging applications, theatre rigging—by its very design—often calls for unprotected actors to walk around in the area beneath thousands of pounds of enormous flown hardware, electronics, and scenic elements.

The Hidden Cost of Friction: Infographic

Pulleys are wheels, but they’re not frictionless. Sheaves rest on axles, bushings, and bearings that contact a pulley block. As that pulley rotates, any friction in the system will slow it down. Even small differences in pulley friction can have a massive impact on loads. But how much? What happens...

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.

Hardware For a Stage Curtain Pulley System Must Overcome 6 Challenges

Theatre rigging requires hardware and equipment that is specialized for the challenges presented by the stage.  Here are a few of the challenges your stage curtain pulley system can expect to face:

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.
