The extent of your crane system doesn’t have to end at the tip of your hoist hook. There are a myriad of accessories, add-ons and attachments that can complement your lifting equipment and make your material handling needs even effortless.
The type of attachment depends heavily on the industry and material type as some applications require a different approach. For lifting flat sheets of material, a magnet or vacuum lifter may be the best bet, however if the load is more cumbersome or oddly shaped, a cady lifter and rigging accessories would be more advantageous.
Lifting magnets are available with permanent, electro-permanent, battery powered, and electromagnetic technologies and are best utilized with the material handling of metal materials.
Permanent - Within the magnetic lifter are two sets of magnets. One of these magnets can be physically rotated by a lever to reverse the polarity thereby controlling the magnetic field. Adversely, the magnets can be rotated towards each other, which moves the magnetic field inward and effectively turning the lifter off
Electro- Permanent - Works in the same way a Permanent magnet does, however the polarity can be switched with an electric current, rather than manually.
Battery Powered - The magnetic current of these lifters can be controlled via battery power rather than manually or with an electric current. This frees them of restricting cords and wires and allows for their use in areas where electric power is unavailable.
Electromagnetic - The magnetic field is produced by an electric current. By utilizing this technology the magnetic field can be quickly changed depending on the amount of current which allows it to lift heavier loads and be a more diverse magnet overall. However, this requires a constant supply of current to maintain the magnetic field.

In some cases, magnetic lifters can be ineffective if the material being lifted is incompatible with a magnet, such as plastic or glass or if the material is highly fragile and requires a more delicate approach.
Vacuum lifters can be supplied as basic as a handheld suction cup or as complex as a pump-powered, multi-pad device. A vacuum lifters cups or pads are usually comprised of synthetic materials such as silicone and nitrile, making them soft and malleable. These are connected by pneumatic tubes to a pump which can be controlled automatically, manually or remotely.
Once a proper seal is created between the suction devices and the material, they can both be elevated and manipulated through the work environment.
Vacuum lifters are commonly utilized for the handling of large flat materials, such as sheets of metal and glass. However, vacuum lifters are also employed in the food industry for packaging purposes (such as distributing raw eggs into separate cartons), as well as the shipping industry to aid in the quick loading and unloading of containers.
