3.0perations


3.1 During operation, you should clear away the components surface such as rust and bur. The centerline of lifter had better overlap with the centerline of component. Then place the Magnetic Lifting Hoist on the face of component, turn the handle from "OFF" to "ON" until "holding". Make sure that the security key on the handle is automatically locked, and then start to

3.2 During lifting and handing components, overloading is forbidden. Nobody is allowed to pass through under the component held by Magnetic Lifter. Components temperature and ambient temperature shall be between +80•C to -40•C. No strong vibration and impact.

3.3 When lifting and handling cylindrical components, keeping the cylindrical surface contacting the Vee Slot of lifter on two lines, the actual lifting capacity will
Generally be 30% of the rated lifting capacity.

3.4 When lifting and handling operation is finished, press down the bottom to disengage the security key from the security pin. Then turn the handle "ON" to "OFF" until "Release". The lifter is in the neutral condition now. It can be taken away from the component.

4.Main factors which influence the lifting capacity of permanent Magnetic Lifter.

4.1 Influenced by thickness and surface quality of the component. Before operation, it is necessary to find out the percentage of the steel thickness-lifting capacity. According to the thickness of the component and capacity curve (on the following page). If its surface roughness Rates less than 6.3um,the lifter surface gap will not exist, the lifting capacity will be 100%. If the surface roughness Rates above 6.3um or even worse, the lifter surface gap should be estimated. Find out the percentage that lifting capacity of the lifter may reach from the air gap-lifting capacity curve shown in the performance chart. Combine these two factors and calculating the lifting capacity that the lifter may reach. The curves are on the two sides of lifter.

4.2 Influenced by the composition of steel component

After measurement, if low-carbon steel component is regarded as reference and the coefficient of lifting capacity is fixed: the coefficient for medium-carbon steel is 0.95; the coefficient for high-carbon steel is 0.90; the coefficient for low-alloy steel is 0.75, and the coefficient for cast iron is 0.50

5.Maintenance and safety notice

5.1 While carrying and using permanent magnetic lifter beware of the bumping and roughness of surface. So as not to influence its property and life-span. After using, the lifter had better be protected by oil. 5.2 Please read the operating instruction carefully and know its property before using this lifter to avoid accident. Please contact our company for further detail. 5.3 Check the quality of the handle button frequently. Make sure that the security key can be moved flexibly and the security pin can be locked firmly. 5.4 When Magnetic Lifting Hoist is not in contact with ferromagnetic material of component, don¡¯t turn the handle. 5.5 Maintenance must be strictly according to the instructions by the professional authorized technical personnel. 5.6 Prohibit modifying the products to avoid effecting on their safety. 5.7 Must take a test for the capability every year and check the safety of all of the components in order to ensure its use capability. 5.8 If its main body and turning part is damaged so that it can not work, it should be discarded as useless.

Neodymium, or Neo, is made up of Neodymium Iron and Boron and is moderate in price. With poor corrosion resistance this alloy is usually plated or coated (Examples: Nickel Plated, Epoxy Coated, Parylene Coated). Neodymium is offered in a range of operating temperatures depending on your application (80•C to 200•C). Premium Neodymium Alloys capable of operating above 120•C can become quite expensive. This permanent magnet material has many intellectual property rights associated with it and there are a limited number of licensed manufacturers in the world. Many infringing manufacturers from the Pacific-rim dump sub par material into the Western markets. This magnet material is extremely powerful and it has allowed for the miniaturization of many products from HDD (Hard Disc Drives) and motors to novelties and audio devices. Neodymium permanent magnets usually offer the best value when comparing price and performance.

Neodymium Iron Boron (NdFeB) and Samarium Cobalt (SmCo) are called Rare Earth because Neodymium and Samarium are found in the rare earth elements on the periodic table. Both Neodymium and Samarium Cobalt alloys are powdered metals which are compacted in the presence of a magnetic field and are then sintered.

General Description:
Magnetic assemblies provide up to thirty times the strength of individual magnets, making them useful in many industrial applications in the construction, engineering, automotive, electronic and agricultural industries, etc. Magnet assemblies are used for mounting, lifting, holding and transferring objects, such as pot magnet, magnetic channels, magnetic catchers, plates, wheels etc. In order to install magnet assemblies, make sure the demagnetizing field is parallel to the pole pieces. Also, be sure that at least half of the length of the holding assembly is outside the maximum demagnetizing field. To easily remove the part, mount the assemblies with their pole pieces parallel to the direction of release motion. In applications where gravity is a large part of the release mechanism, pole pieces are mounted parallel to the ground.
 
When selecting magnet assemblies, consider the environment in which the assembly will be used, like temperature. What is the holding force needed based on the size and weight of the parts involved and how will the assembly be secured, whether bolted, mounted, fastened or adhered? Also, consider the shape of the magnet desired (e.g. disc, ring, rectangle, etc.) and the size, including diameter, length, width and height. Knowing what variation in dimensions is allowed (tolerances) is important. Price and quantity are also considerations.
