The role of a rigger is to ensure that the mechanical device to lift heavy loads is safe and secure. Rigging is a technical trade that requires care, precision and patience. Coupled with knowledge and experience, a rigger relies on quality rigging equipment to successfully create a mechanical apparatus to lift heavy loads with the aid of a crane, hoist or other lifting device. It is important to invest in quality rigging lifting equipment so that the work can be completed perfectly, safely, on time and with no complications.

Employers must have a qualified rigger if they are going to be hoisting objects for assembly, disassembly, or hook or unhook loads. Total Equipment Training offers OSHA-qualified rigging certification training for your business so you can be sure you are complying with guidelines and keeping employees safe. Keep reading for some of the information covered in a Total Equipment Training rigging certification course.

Wire rope is an extremely versatile mechanical device that can be used to help support and move an object or load. Whether for use on cranes or for other lifting applications, it’s important to have a solid understanding of the rigging components that are being used to attach to and lift a load.

This section is dedicated to our selection of rigging hooks. We carry hooks made for virtually every application, from foundry hooks that are designed to detach from a load easily, to heavy-duty Self-Locking Hooks that close automatically for added security.Hooks may be used in top-loading, lifting, winching, towing, or any number of other applications. We carry Clevis Grab Hooks, Eye Hooks, Weld-On Hooks, and Clevis Slip Hooks.

Rigging and lifting hooks for cranes, hoists and slings are an essential part of almost any rigging application. Choosing the correct rigging hook for your lifting application is just as important as choosing the correct sling or hoist. Lifting hooks come in a huge variety of designs, materials and sizes, all suited for different lifting applications. Some of the most popular types of hooks used in the rigging and lifting industry are:

Understanding the function of different lifting hooks is essential in ensuring the proper and safe operation of materials during handling operations. Lifting hooks come in many shapes, sizes, and applications to suit your needs – but it can be challenging to figure out which one is right for the job.

When rigging and lifting a load, it is important the hook is correctly positioned where the weight of the object listed is applied in the bowl or saddle of the hook. Side, back and or tip loading are conditions that reduce the hook's lifting capacity and can cause damage to the hook (see illustration below).

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.

When rigging and hoisting items, you’ll need several pieces of hardware. One of the most vital pieces of hardware is the hook you choose. What a lot of people don’t know, however, is the different types of lifting hooks and sling hooks. If you’d like to learn more, we’ve got you covered in our list below.

When a bolt is tightened into a mating threaded part, the two components interact by pulling each other together. This force is called clamp load and is what keeps the joint from coming apart. Provided that the force pulling it together is greater than the outside forces (service loads) that are trying to pull it apart, no problem will result with the attachment. Unfortunately, friction plays a large part in this system. Of the 100% of torque applied to fasteners to pull them together, 50% is lost in underhead bearing face friction and 40% is lost through friction between the mating threads.

Shackles are the primary connecting link in all manner of crane systems that allow different rigging subsets to be connected or disconnected efficiently and safely. However, it’s essential to understand the specifications and limitations of shackles before using them to avoid accidents. In this blog, we’ll discuss the essential dos and don’ts about shackles. Let’s begin!

Shackles are critical for different types of industrial lifting and rigging applications. They provide you with safety and efficiency when handling heavy loads. It is, however, necessary to choose shackles well suited to your application because not all of them are made equal. If not, you would end up with serious injuries or damages.
