Lifting and Rigging Supplies

There are many factors that will influence the price of lifting and rigging supplies. These include where you buy, what you need and how quickly you need it.

When purchasing rigging equipment, it’s important to choose a supplier that has experience catering to the industry. The right supplier will ensure that you get the best bang for your buck in terms of both quality and price.

Spreader bars

A spreader bar is a useful tool for safely lifting loads. However, lifting and rigging supplies if it is used incorrectly, it can cause serious safety mishaps. These can include putting too much strain on the bar’s hook mechanism, side pulls, or even damage to the load. To avoid these mistakes, follow the guidelines for use, inspection, maintenance, and reevaluation of spreader bars. It is also important to keep in mind that spreader bars must adhere to recommended rigging geometry and bear labels with the manufacturer’s capacity ratings. In addition, unauthorized personnel should not remove or modify the bar’s markings and tags.

A spreader bar consists of two lugs that attach to lower legs of chain slings or synthetic slings. This allows the load to be evenly distributed and reduces bending forces. It can also help prevent the load from slipping or spinning during the lifting process. Moreover, spreader bars can be used for heavy and wide loads that require significant lifting. They are also more compact and less expensive than a lifting beam. However, they may not be suitable for situations where there are height restraints or limited overhead space.

Pulleys and blocks

Pulleys and blocks are essential for reducing the amount of force needed to lift heavy loads. They are used with rigging ropes, which are looped around the block and then hooked to the object that needs to be lifted. They are available in a range of sizes, depending on the frame type and sheave size. There are also snatch, square, and swivel blocks, as well as single and double pulleys.

The block distributes the load evenly, which reduces the amount of force required to lift it. This makes it easier to lift heavy objects and saves time. The block also increases the mechanical advantage of the system. You can calculate its mechanical advantage (IMA) by dividing the force exerted by the number of sheave segments.

The block consists of a wheel with a groove in it and an axle, which allows the wheel to rotate. It is attached to another block by a revolute joint, which gives it one rotational degree of freedom. A snatch block is designed to open with a gate on the side, making it easy to thread wire ropes through the axle.

Steel nuts

Whether used in construction or putting together furniture at home, steel nuts are a great way to keep things securely fastened. They come in many different shapes and sizes to suit the needs of specific projects. They can also be made from different materials.

For example, some are electroplated with zinc for better corrosion resistance. They are usually tapped slightly larger than standard nuts to accommodate the coating. Stainless steel nuts are a good choice for environments that can be exposed to saltwater. They are highly resistant to corrosion and are also durable.

If you’re working with a threaded bolt, it’s important to match the nut with its bolt. The nut should Lifting and Rigging Supplies Manufacturer be at least as strong as the bolt, otherwise it could break under pressure. Alternatively, you can use eye bolts that have a closed loop on one end. They can be screwed into threaded holes or welded to the material they’re attached to. They should have a stamped WLL, or working load limit, to indicate the maximum amount of weight they can support.

Rigging hooks

Rigging hooks are used to connect chains, ropes, and slings during lifting operations. These hooks are made from forged alloy steel and come in different sizes and capacities. They can be attached to cranes and hoists or directly onto a load. The type of rigging hook that is right for your project will depend on the size of your load, how high you need to lift it, and the type of materials you’re moving.

There are several types of rigging hooks, including eye hooks, clevis grab hooks, and positioning swivel hooks. Some of these hooks can rotate up to 360 degrees, which allows them to be more maneuverable during the lifting process. Other hooks can be secured to a load using a shackle, which is comprised of two free ends with a pin that’s locked into place.

Some rigging hooks are also stamped with indicators that help ensure they’re being used correctly. These indicators, known as QUIC-CHECK, are located in the throat opening of the hook and mark the minimum breaking strength and working load limit (WLL) for the device.

Rod end bolts

Eye bolts are versatile metal fasteners with a threaded rod on one end and a loop for attaching wire rope or hooks. They are used in a wide variety of light-duty hanging, lifting and hoisting applications and are usually made from stainless steel or galvanized metal to resist corrosion in wet environments.

When selecting a metal eye bolt, consider the manufacturer’s recommended working load limit (WLL), which is typically stamped on the device. These ratings are based on the maximum amount of weight that the equipment or structure can safely support.

Like other types of rigging hardware, eye bolts come in a variety of designs and configurations and can be used in a wide variety of lifting, anchoring, pulling, pushing and hoisting applications. However, they are also among the most misunderstood pieces of hardware and misused, which can increase the risk of equipment failure or injury. To prevent this, know how to choose and use the right type of eye bolt for your job and make sure it’s seated correctly. There are several different types of eye bolts, including nut eye bolts, machine bolts and screw eye bolts.
