Your Complete Guide to Rigging Services
If you need to move heavy, delicate or hard-to-reach equipment, you don’t want to hire a traditional moving company — you need a rigger. In this article, we’ll cover the duty of a rigger, the equipment they use and the basic rigging safety practices they follow.
What Is Industrial Rigging?
When you buy a house, you will often use a moving company to move your belongings. Similarly, when a company moves to a new location or buys new machinery, it must hire riggers, a term for professionals who specialize in moving heavy industrial equipment. Local rigging services can be as simple as moving machines to a different location within a facility or as extensive as hauling them to another state.
Typical moving companies can’t handle industrial machinery for several reasons.
- Weight: Manufacturing and heavy machinery can weigh 20 tons or more, meaning that the forklift and pallet jacks traditional moving companies use won’t do the job.
- Sensitivity: These equipment pieces can also be sensitive and feature calibrated meters or gauges that must provide specific readings. Most moving companies do not have the equipment or training to handle such delicate machinery.
- Location: Many industrial machines often sit in tight spots, making it challenging or impossible for typical moving companies to transport them.
Using specialized equipment, machinery riggers can haul a wide variety of equipment, including generators, HVAC units, semiconductor equipment, printing presses, safes, conveyors and mills. However, just because a company specializes in rigging does not necessarily mean it can move your equipment. For a rigging contractor to be effective, they must thoroughly understand your equipment, your project’s scope and the required safety practices and permits.
What Are the Types of Rigging?
Industrial rigging companies move everything from hydroelectric dam generators to MRI machines. While every project is different and presents unique circumstances, some everyday situations where riggers play a vital role include:
- Plant reorganization
- Plant relocation
- Machinery upgrades
- Dismantling and removing decommissioned machinery
- Crane rigging
- Assembling and installing new equipment
They also work for a wide range of industries, many of which have equipment that requires special handling. What are rigging services? Some examples include the following.

What Are Examples of Rigging Equipment?
To keep the lift and worksite safe during a rigging project, it’s vital to have the correct equipment and understand each machine’s function and purpose.
The most useful essential piece of equipment a rigging project is a crane. However, when choosing the right crane for the job, you need to consider the three following things.
- Lift capacity: Ensure the crane you pick has the lift capacity for the job.
- Maximum lifting height: Can the crane you’re considering go high enough to clear all obstacles?
- Horizontal reach: Is the crane’s reach long enough to get the load from where it is to where it needs to be?
You can find all the above information on the crane’s load chart. Once you’ve found the best crane for the job, the next step is to determine the rigging equipment you need for the project. A wide variety of rigging parts exist. Some of them are essentials, whereas others are only for specific lift types. Below, we’ll explore the components most commonly used for rigging projects.
The primary connection between the load you’re lifting and the crane is the rigging hooks, which riggers choose based on their weight load capacity. They generally consist of forged alloy steel and various types exist, including automatic, eye, swivel, chain, clevis and shan hooks. They’re also available in many sizes based on the hook’s throat, or opening. Experienced machinery riggers can determine the type and size most appropriate for the job.
When rigging a crane, shackles serve as the main connecting links and allow quick connection and disconnection of various rigging parts. Shackles are one of the most prevalent fittings for rigging, and are typically the solution when a load weighs over 6,000 pounds. Due to their removable pin, they can connect to ropes, slings, cables and the like.
Various kinds are available, but all shackles feature a U-shaped design with an opening secured by a clevis pin or bolt. The most commonly used shackle types in rigging include the following.
- Anchor: Also known as a “bow” shackle, an anchor shackle features a bow with a large, round “O” shape. This larger bow shape enables this shackle to be side-loaded. You can also use it in multiple sling-leg connections.
- Chain: Chain shackles, or “D” shackles, feature a narrower, D-shaped bow. This kind of shackle is for in-line tension and shouldn’t be side-loaded, which can cause bending or twisting of the shackle’s bow. When you use a chain shackle, the load’s centerline and the shackle’s centerline must coincide.
- Long-reach: A long-reach shackle is ideal for situations that require a longer reach to connect to pick points. You can also use them as a bail to lift thicker products.
Wire Ropes and Nylon Slings
You use wire ropes and nylon slings to connect a large load or span its perimeter. In rigging, wire ropes consist of many strands of carbon or stainless steel rope twisted around a core rope. A wire rope sling comes in various lifting capacities, which provides users with a flexible, strong lifting solution.
This modular lifting solution enables various configurations, depending on the lifting operation’s lifting requirements. You use a spreader bar below a hook when you rig a heavy or large load, which distributes the load over multiple points. This setup increases stability and decreases the loads applied during hoisting. You can use spreader bars with both wire rope slings and synthetic lifting slings.
Some projects require rare equipment, such as tri-block rigging systems or modular lift towers. These come in handy in tight spaces with only enough room for a single crane to “self-tail” equipment. Tri-block rigging for loads weighing up to 200 tons makes using a work platform or second crane unnecessary and provides a safer option for cantilevered operations and transferring equipment between lifting apparatus.
Workspaces with limited space can also benefit from modular lift towers. However, they are particularly advantageous for sites with less-than-ideal ground conditions or remote locations. While moving large cranes to sites like these can be very challenging, dangerous and costly, it’s possible to move modular lift towers in sections and assemble them on site. They’re often useful in congested factories, refineries and power plants.
Rig Safety Solutions and Considerations
Operating rigging machinery requires intense focus and preparation to ensure everyone is safe and avoid equipment and property damage. To secure a rigging operation, familiarize yourself with this lifting rigging safety checklist.
- Work only with qualified people: All workers on a site should be familiar with rigging safety practices. They should understand the equipment and have the training to comply with rigging procedures. Professionals should foresee issues before they occur and know how to immediately stop machines if working conditions become dangerous.
- Perform a thorough examination: Before beginning a lifting project, have a rigging professional inspect the handling equipment and the crane to ensure its safety. Address every technical issue — no matter how minor. Only use machinery that’s in top condition. You should also consider weather conditions, as inclement weather can make lifting more dangerous.
- Note any technical problems: If you notice that a machine has technical issues that could lead to a malfunction, do not use it for your rigging project — take it out of commission and store it for repairs. This policy is especially crucial if more than one employee on the job site will operate a crane.
- Ensure a balanced load: Perhaps the most universal rigging and moving safety tip is that the load hook and upper suspension should form a straight line. Ensure that chain and the hoist body never touch the load. Also, be aware of how far a load can swing. If a load becomes unbalanced, this may cause the crane to tip over. Always be mindful of the load capacity and its center of gravity.
- Ensure the load cannot cause injury: For rigging equipment safety,don’t allow employees to stand or walk underneath a suspended load. The operator is responsible for keeping loads separate from other workers. Those close to the lifting should make sure their hands, fingers and feet stay away from pinch points. It’s also critical to avoid touching power lines, which can cause electric shock.
- Land all loads: Loads should never stay suspended when the machine is off. Whenever it’s not possible to supervise the hoist, lower the attached loads to the ground. Be aware of any stacked material near the load, so you won’t knock it over. The landing area should also be clear before the operator slowly lowers the load.
- Use only strong slings: A sling must be strong, durable and able to lift heavy objects. It’s a good idea to measure each sling leg’s tension, which must match the slings’ vertical capacity.
- Designate a spotter: As a rigger, if you don’t have a full view, you must designate a spotter who will be in charge of directing the loads and ensuring proper clearance. Always be aware of where workers are versus the load.
- Be thoroughly familiar with your equipment: A rigger should know their machine’s weight capacity, which they can find in the load charts located in the manufacturer’s operator’s manual. The rigger should be familiar with the load radius and boom length as well. When balancing a load, the maximum angle capabilities and the number of legs on the machinery are essential.
- Safely store hook or hoist: At a project’s conclusion,store the rigging equipment somewhere where weather and other factors cannot damage it. It must also be somewhere that won’t be potentially hazardous for people.
