Wire rope thimbles also known as cable thimbles, are used for making reinforce loop(eyelet) with grips, clips or clamps by preventing fraying caused by friction at the bearing anchor point to protect and extend the service life of the wire rope or sling. They are just one of the many types of wire rope fittings (ferrules, wire rope clips, terminals, etc.).
A shackle, also known as a gyve, is a U-shaped piece of metal secured with a clevis pin or bolt across the opening, or a hinged metal loop secured with a quick-release locking pin mechanism. The term also applies to handcuffs and other similarly conceived restraint devices that function in a similar manner. Shackles are the primary connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly. A shackle is also the similarly shaped piece of metal used with a locking mechanism in padlocks. A carabiner is a type of shackle used in mountaineering.
The rope, like the wheel, is a very important tool in human history. Much like the wheel, it is a simple invention that completely changed the capabilities of man. It allowed the earliest inventors to pull heavy objects, connect objects, and bind objects together. Furthermore, the combination of the rope and the wheel gave rise to pulleys, devices that are still used heavily today.
What are hoists? A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism. Most hoists couple to their loads using a lifting hook.
It is a simple wooden or metallic machine that uses a wheel and rope to lift heavy loads. Nowadays, plastic pulleys are also available in the market to carry small loads. This can be rotated freely about an axis passing through its center. It can change the direction of a force which makes it much easier for people to lift anything. With this, you can pull down on one end to lift the 10 kgs and one-meter high object.
Are you planning your next overhead lifting project and need to specify the type of sling and rigging equipment you’ll be using? While it’s important to understand the best type of sling to use, it’s just as important to select the right type rigging hardware that will be connected to that sling. Choosing the right type of lifting hook that can be used will be determined by a number of different factors.
A snatch block is a specific kind of pulley, a simple device that makes it easier to lift or pull a heavy load with less force. It’s sort of a strengthening mechanism. All pulleys use a spool and casing to hold a rope.
