Pulley Sets – Product Focus

Pulley sets are used in order to make it easier to move a load through the use of mechanical advantage. In simple terms, mechanical advantage is the ratio of the force produced by the system compared to the force applied to the system. For example, a 2:1 mechanical advantage system reduces the force needed to lift a load by half.

Capstan Winch – Product Focus

A winch uses a set of gears to provide mechanical advantage to move a person or load. A winch allows a single person to easily move a load many times heavier than they would be able to simply by pulling on a rope or cable directly.

A Few Thoughts On Safety Recalls

DMM Wales has recently announced a recall for some products which integrate their compact swivel design. Why do recalls happen? In general, safety recalls occur when a product could potentially lead to a situation resulting in a substantial risk of injury. This could result from a problem in the initial design and construction of the product or it could be from a problem which develops over time while the product is in use.

Carabiner Questions and Answers

Carabiners are a type of connector used in rope access, rope rescue, and arborist work to join two pieces of equipment together. They go by many names including snap links, biners, and karabiners. They are available in a large number of styles and materials with various types of closing mechanisms. We receive a lot of questions about carabiners and here are the answers to some of them. If you have additional questions please ask us in the space at the bottom of the page and we will answer them for you. How do I pick the right carabiner? The first step is to determine how the carabiner will be used. Will it be used for lifting equipment or people? How much weight should it be expected to hold? What type of conditions will it be used in? Is it a dirty environment? Is it close to salt water (ocean)? These

Pulley Questions And Answers

A pulley is a wheel which rotates on a shaft designed to reduce friction. They can either be used to change the direction of a rope or provide mechanical advantage to make it easier to move or lift an object. In rope systems, pulleys are primarily used to build mechanical advantage systems for raising operations. We receive a lot of questions about pulleys and here are the answers to some of them. If you have additional questions please ask us in the space at the bottom of the page and we will answer them for you. How do I pick the right pulley? The first step is to determine how the pulley will be used. Will it be used for lifting equipment or people? Will the pulley add mechanical advantage or simply change the direction of pull? How heavy is the load? How high do you need to lift? What
