A well-designed pulley, such as the above mentioned 2-stage bearing system, will remain highly efficient across the full working load range. However, some ball bearing pulleys may produce great results at a low load, then rapidly lose efficiency as the load increases.
The construction method of any rope, braided or twisted, can tell us a lot about its performance and utility. The rope’s shape, strength, and general characteristics can all be impacted by the construction of the rope.
Pulleys are often referred to as blocks, and for the sake of this article we will consider the terms ‘pulley’ and ‘block’ to be synonymous. How are they measured? When someone refers to a pulley by physical size, most commonly they will be referring to the diameter of the sheave. The sheave is the wheel >>
While the exact origins of the pulley system are not known, it is believed that by 1500 BC some of the first pulley systems were being utilized for hoisting water in Mesopotamia. Although modern technology and pulley systems have changed dramatically, the unmistakable value of a pulley system remains unchanged.
Properly tensioning a shading system can be complicated, but it doesn’t need to be impossible. Getting it right is critical to the stability and durability of the structure. Too little tension, and the structure risks damage from wind or pooling water. Learn more...
A parrel is a loop, typically made of rope or wire, that can be wrapped around an object to help it be hoisted, lowered, or moved. To avoid chafing, friction, and excess wear, the parrels are sometimes lined with plastic parrel beads which act as roller bearings to help the loop slide along the surface >>
