Rigging

The planned movement of material and equipment from one location to another using slings, hoists or other types of equipment. All operations must be done under the supervision of a competent person.

The connector or link between the load and the lifting device and is made of synthetic, chain or wire rope materials.

Must be securely attached to each sling and clearly marked with information required for that type of sling

Manufactures name or trademark and the rated capacity of the type of hitch used with that sling.

The maximum load weight that the sling was designed to carry.

Are widely used to lift loads especially easily damaged ones.

They are used to let the rigger know whether the sling has suffered too much damage to be used. If they are exposed the synthetic web sling should not be used.

Also called Endless Web Slings

Are endless and made in a continuous circle out of polyester filament yarn.

Are made by sewing an end of the sling directly to the sling body.

Are used to help the rigger determine whether the sling has become overloaded or stretched beyond a safe limit.

Are made by wrapping a synthetic yarn around a set of spindles to form a loop. They are made of synthetic fiber such as polyester.

Are usually made of synthetic fibers, but they also can be made of natural vegetable fibers us as sisal.

Are made by using one stand of the same size and type as the rest of the stands of rope.

Are made of a separate wire rope with its own core and strands.

Its suppose to support the strands so that the stands keep their original shape.

Term that defines the lengthwise distance it takes for one strand of wire to make one complete turn around the core.

The way the sling is arranged to hold the load.

Is used to lift a load straight up and form a 90 degree angle between the hitch and the load.

Consists of two or more vertical hitches attached to the same hook, master link or bull ring. It allows the slings to be connected to the same load without the use of such devices as a spreader beam.

Is a stiff bar used when lifting large objects with a crane hook.

Provide increased stability for the load being lifted and is always considered to have only two of the legs supporting the majority of the load and the rest of it balancing the load.

Is used when a load has no attachment points or when the attachment points are not practical for lifting. It is made by wrapping the sling around the load and passing one eye of the sling through a shackle to form constricting lop around the load.

Are very versatile and can be used to lift a variety of loads. It is formed by passing the sling around the load and placing both eyes in the hook.

It combines the constricting power of the double wrap choker hitch with the capacity advantages of a basket hitch meaning that it is able to hold a larger load more tightly.

To lift a bundle of loose items or to maintain the load in a certain position during transport and it made by wrapping the sling completely around the load and then wrapping the hoke end around again and passing it through the eye like a conventional choker hitch.

An item of rigging hardware used to attach an item to a load or to couple slings together.

An item of rigging hardware with a threaded shank. The shank end is a attached directly to the load and the eye end is used to attach a sling to the load.

Are designed for vertical pulls not angular pulls.

Can be used for some angular pulls.

Are specially designed for angular pulls and the surface must be flush with surface of the load or it will not function any better than an unshouldered eyebolts.

Is designed so that the shank passes completely through the members it connects.

Has a straight shank with a conventional head such as a square or hexagonal head.

Are used to move loads such as steel plates or concrete panels without the use of slings.

An item of rigging hardware used to attach a sling to a load.

Are the most common type of end fitting hook that may or may not have safety latches or gates.

Are used to lift pipe sections or containers by inserting the hook into the load thereby avoiding the need for shackles or additional hardware.

Position the point of the hook perpendicular to the eye.

Are installed onto the sling when it is made and the hooks can positioned anywhere along the sling body and are used to secure the sling eye in a choker hitch.

Are used on steel chain slings and they fit securely in the chain link so that choker hitches can be made and chains can be shortened.

A more efficient version of the grab hooks provide a secure grab of the shortened sling leg with no reduction in the capacity of the chain because the clutch fully supports the links.

One of the most important facts need to know to conduct rigging safely.

Provide a mechanical advantage for lifting a load allowing to move objects that you cannot lift manually and use a pulley system to transmit power and lift a load.

Is a simple rope and pulley system used to lift loads.

May be operated manually or mechanically. Mechanically includes electric and pneumatically.

Means the same thing as the working load or a safe working load and must be determined to make sure that loads that are safely and effectively lifted and transported.

The process of analyzing the work area and the details of the lift prior to beginning the lift and it allows you to forsee potentially dangerous situations and to develop a plan that will help avoid them.
