Differences in Lifting Magnet Models
Lifting magnets are widely used in the steel industry and are often found to be beneficial when lifting materials within ship yards, scrap yards and warehouses. Capable of lifting both cubic and spherical materials within a weight range of between 100kg and 2000kg, these permanent lifting tools offer a low cost, functional and highly efficient solution to lifting and moving ferromagnetic materials.
These magnets are adaptable to be used in a wide range of scenarios that use steel materials and require maximum lifting power. They can be safely used in conjunction with a range of cranes and other electric hoists to easily lift more weight. All magnets are designed with a built in safety locking handle to remove any potential risks or safety issues and effectively prevents your load from ever being able to come loose.
Permanent magnets have the added benefit of having no on-going running costs and can all be installed and operated by just one man. The strong magnetic capability means that the contact point between the material being lifted and the lifter never leaves a residual mark or impression, thus reducing any potential damage to your stock and the replacement costs associated with this.
All lifting gear is fully tested before release and issued direct to you with full certification to prove their weight lifting capacity.
At the low weight lifting end of lifting models, weight bearing capacities of up to 100KG only require a thin metal to achieve maximum lift capacity, with a standard 15mm thickness provided to reach optimum lifting power.
In contrast, a 2000KG magnetic requires a metal thickness of 55mm to safely connect to and lift your material loads. It is therefore imperative that you take into consideration the full weight and thickness of the metal you need lifting most frequently when deciding which lifting magnet to use in order to achieve maximum clamping force.
You must also consider the standard length of your materials before selecting a lifting magnet as you will require a more powerful magnetic connection to be made, the longer your materials are. A lifting magnet with a weight capacity of 100KG can lift a restricted material length up to 2000mm in length, whereas the most powerful 2000KG magnet can lift materials extending to a length of anything up to 3500mm.
Please bear in mind that if your chosen material to be lifted is spherical the surface in contact with the magnet is somewhat minimized and this will impact the magnetic lifting ability by half of that compared to flat faced materials.
Another consideration to be made is that there is often the potential for air gaps or pockets to occur between poorly fabricated surfaces or where paint and dust particles might have settled. Some materials may also be sent to you containing dents, holes or abrasions. If working with such materials, for your safety it is advised to use the next lifting capacity up for the required weight as these anomalies will certainly reduce the optimum lifting capacity of your magnet to below safe working loads.
Working in extreme temperatures and humidity will also impact the effectiveness of all lifting magnets, as do various non pure forms of steel such as carbon steel, alloy steel and cast iron. Ensure full consideration is given to the full specification of all materials to be lifted and the environment you will be worked within before selecting the correct lifting magnet for your needs and your magnetic lifting success will be assured.
