Types of Rigging Hardware

Types of Rigging Hardware

Rigging hardware plays a crucial role in construction projects and is necessary for securing heavy loads. It must be strong, durable and capable of withstanding jolts, compressions and twisting.

Spreader bars make carrying loads more manageable and stable by spreading the weight across multiple connection points. They are also commonly used in conjunction with pulleys.


A dynamometer is a device used to measure the power and speed of machinery. They can be used to test everything from engines to motors and are available in a wide range of sizes. They are usually made from metal alloys and built to withstand the heavy use they will receive. Many manufacturers have a variety of different options to choose from so that they can provide the perfect tool for any customer’s needs. For example, some dynamometers are designed to be used with water brakes while others are meant for eddy current brakes.

There are two main types of dynamometers: absorption and universal. The former lifting and rigging supplies uses a rotor to absorb the energy of an engine or piece of equipment and then converts this energy into heat. This heat either dissipates into the air or is transferred to cooling water.

The latter is more common and has a wide variety of applications. They are commonly used to test cranes and other large scale equipment. Some dynamometers are also used to measure tension in rigging. These devices are often known as Load Pins, Shear Pins or Clevis Pins and they can be found in a variety of equipment. They are often configured with strain gages and monitors to record and display readings.

Cable Clamps

Cable clamps are used to secure wire and cable bundles in a variety of different situations. They eliminate the need for tape and other types of fasteners that leave behind sticky residue or are less permanent. They also protect a wire or cable from damage and help to prevent it from becoming a trip hazard by keeping loose ends in check.

There are various types of cable clamps, including the U-bolt type. These consist of a U-shaped bolt and two nuts that can be tightened to hold the cable. These are typically used in rigging applications, such as creating end loops for crane or winching cables.

Another common type of cable clip is the double saddle clamp. These are similar to the U-bolt clip, but they have mirrored saddles that allow them to fit into each other. This allows you to use them in both directions without having to switch out the bolts. These are typically used in rigging and lifting applications. These include creating end loops for winching or crane cables, extending perimeter cables, and increasing the length of a wire rope going through a D-shackle or eye bolt.


Blocks are deceptively simple, but offer a rich platform for a wide range of learning. From emotional growth and resilience to art, visual-spatial practice, and problem-solving skills, research has confirmed what parents, kids and teachers have known for centuries — playing with blocks is not only fun, but really good for you.

The s-block of the periodic table is dominated by soft metals with generally low melting points and boiling points that readily form ionic compounds with non-metals and the electronegative halogen non-metals. In contrast, the p-block of the periodic table is dominated (aside from helium) by elements with high oxidation states and by a range of distinctive metals and non-metals that are essential to life.

Rigging terminal fittings come in many shapes and sizes, some more robust than others. It is important to select the right terminal for the job – especially if the rig will be subject to shock loading. Machined eyes are stronger and lighter than forged ones. They also have a chunkier appearance as they retain the internal grain structure of the stainless steel.


Pulleys are a common piece of rigging hardware that can be used to reduce the amount of force needed to lift an object. They can be fixed or movable and have grooves that allow rope to move easily over them. They are easy to use and have a wide range of applications in daily life and commercial work.

The simplest pulley has a fixed axle and wheel. It is like the wheel Lifting and Rigging Supplies Manufacturer on a school flag pole. It does not increase the amount of force applied, but it changes the direction of the force and has a mechanical advantage of 1.

A single movable pulley increases the number of units of the line that are pulled down to the load. It does not change the amount of force applied, but it increases the mechanical advantage to two. The more pulleys added to the system, the greater the mechanical advantage. A compound pulley system is a great way to lift heavy objects, and it was designed by the famous ancient inventor Archimedes.

Steel Nuts

A nut is a fastener with threads that fit on the male threads of a bolt or screw to keep the two partners together. Nuts can be made from a wide variety of materials and have many different types and styles. For example, some are designed to resist loosening due to vibration or rotation by having a locking mechanism such as a serrated flange, nylon insert lock nuts, or castellated nuts.

Steel nuts are often electroplated with zinc to provide corrosion resistance. They can also be hot-dip galvanized to improve their durability and lifespan in an outdoor environment.

Stainless steel is an ideal material for rigging hardware as it is resistant to rust and corrosion. It can be used for both light and heavy rigging projects, and it can be manufactured with various grades to suit the application. It’s important to match the strength of your rigging equipment to the Working Load Limit (WLL) readings of your project to ensure the safety of everyone involved. This is why it’s essential to use only high-quality hardware and check all components before using them in a live setup.
