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...

4 Properties to Prioritize in Synthetic Rope for Shade Systems

Shade sails, shade cloths, and other fabric shade systems are all tensile structures—they rely upon ropes to keep the fabric elements anchored and held taut.  While synthetic ropes have eliminated many of the drawbacks common to organic fiber ropes (like susceptibility to mildew or rot), they also...

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.

Three Reasons to Change from Wire to Fiber Rope

Synthetic fiber ropes have advanced to the point where they have surpassed steel cable, size-for-size, in strength (sometimes by up to 20% or 30%) while also remaining as much as 85% lighter.

Sheave Groove Shapes for Fabric Structures

When considering sheaves or pulleys for a shade structure it is important to consider the profile of the sheave as sheaves intended for steel cable differ from those that are ideal for fibrous rope.

Why Torlon is used for Roller Balls, Needles and Bushings in Blocks

Torlon is a fascinating alternative to traditional steel roller balls in pulley blocks, with many of the conveniences common to plastic, but the dependability we’ve come to expect from steel.  The unique traits of this weather-impervious polymer give it a wealth of advantages sought after in...

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...

Lightweight Yet Robust: Ball Bearing Pulley Blocks in Shade Systems

Ball bearings feature multiple races separated by balls through which the loads are transmitted. Pulley systems that utilize ball bearings benefit from this design due to their ability to reduce friction, as the rolling motion of the balls results in a lower coefficient of friction than that of...

Dual Bearing Core Blocks in Temporary Telecommunications Tower Systems

Selecting the right core block for your pulley system is largely dependent on the load conditions that the final product will be subjected to. The primary consideration is whether the system will be exposed to a static load or a dynamic load. From there, the next consideration is the level of...

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.
