1. LIFTER OPERATING INSTRUCTIONS CONTENTS NOTE Please read the Operating Instructions carefully before using this Product If any doubt remains please contact our company for further details 1 APPLICATION AND FEATURES Permanent Magnetic Lifters Model PML is mainly used for connecting component during lifting and handling operation They can hoist moving iron block cylindrical and other magnetic material They are easy for operation safe in handling lightly and ingeniously structured Hence they are widely used as hoisting devices in factories docks warchouses and transportation industries By using them you can improve your working conditions and increase your working efficiency 2 CONSTRUCTION AND SPECIFICATION 2 1 construction MODEL PML Permanent Magnetic Lifter has strong magnetic path produced by NdFeB magnetic materials On and off the magnetic path is controlled by turning the manual nozzle There are shackles on the top of Magnetic Lifting Hoist for lifting a veto slot on the holding face for holding cylindrical component firmly 2 2 Specifications Rated liting Max pull ott if Operation ouad weight Model strength strength L Ww H 1 temperature Ckgt kot kg PML 100 100 50 350 62 92 67 126 lt 80 3 PML 300 300 150 1050 92 162 9 155 lt 80 10 PML 600 600 gt 300 2100 122 232 117 TR 196 lt 80 24 PML 10002. 1000 soo 3500 176 258 163 285 lt 80 50 PML 2000 2000 1000 7000 234 378 212 426 lt 80 N A 125 PML 3000 3000 1500 i 10500 286 458 261 521 lt 80 220 E PML 6000 6000 3000 21000 430 600 355 180 lt 80 420 PML 6000 can produce according to the customer s regest u C 3 OPERATIONS 3 1 During operation you should clear away the components surface such as rust and burr The centre line of lifter had better overlap with the centerline of component Then place the Magnetic Lifting Hoist on the face of component turn the nozzle from OFF to ON until holding Make sure that the security key on the handle is auto matically locked and then start to hoist 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 now in the neutral condition it can be taken away from the component 4
3. 0 Safety capability curve picture 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 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 nozzle 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
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 Ra is less than 6 3um the lifter surface gap will not exist the lifting capacity will be 100 If the surface roughness Ra is 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 a reference and the coefficient of lifting capacity is fixed the coefficient for medium carbon steel is 0 95 the coefficient for nigh carbon steel is 0 90 the coefficient for low alloy steel is 0 75 and the coefficient for cast iron is 0 50 OPERATING INSTRUCTION STEEL THICKNESS AIRGAP MM MM 80 0 5 70 15 74 e Pe 60 mn u 5 afi 50 N 1 Pa AN 0 3 ER AA 20 SS 10 2 15 Pu A rat 000 10er 4 0 1 5 1 LY z V 100 75 50 25 0 100 75 50 25
