Frequently Asked Questions (FAQ) about Permanent Magnetic Lifters

Q1: What is the primary difference between a permanent magnetic lifter and an electro-magnet?
A1: Permanent magnetic lifters use high-strength permanent magnets (like NdFeB) and do not require electricity to operate or maintain their magnetic force. Electro-magnets, conversely, rely on an electric current to generate a magnetic field and require continuous power during operation. Permanent magnets offer energy savings, portability, and are fail-safe against power outages.
Q2: What does "Safety Factor 3.5:1" mean for a pml 1000 lifting magnet?
A2: A safety factor of 3.5:1 means that the ultimate pull-off force (the maximum force required to separate the lifter from the load under ideal conditions) is at least 3.5 times its Rated Lifting Capacity. For a pml 1000 lifting magnet, this implies a pull-off force of at least 3500 KGS, providing a substantial safety margin against accidental detachment, as required by standards such as ASME B30.20.
Q3: Can a magnetic lifter lift materials with a rough or painted surface?
A3: While magnetic lifters can still lift materials with rough or painted surfaces, their effective lifting capacity may be reduced. Any air gap (like paint layers, rust, or uneven surfaces) between the lifter's magnetic poles and the workpiece diminishes the magnetic field strength. For optimal performance and to achieve the full rated capacity, the contact surface should be clean, flat, and free of significant rust or debris.
Q4: What material is typically used for the permanent magnets in a pml magnetic lifter?
A4: Dawei Permanent Magnetic Lifters primarily utilize high-performance Neodymium Iron Boron (NdFeB) magnets. NdFeB magnets are chosen for their superior magnetic strength, high coercivity (resistance to demagnetization), and stability over a wide temperature range, ensuring long-lasting and reliable lifting performance.
Q5: How do I select the correct permanent magnetic lifter for my application?
A5: Consider the following: 1) Maximum weight of the material to be lifted. 2) Shape of the material (flat, round, specific dimensions). 3) Thickness of the material (crucial for magnetic penetration). 4) Surface condition (clean, rough, painted). 5) Operating environment (temperature, presence of oil/debris). Always choose a lifter with a rated capacity well above your maximum load, considering potential reductions due to surface conditions or material thinness. Consult the manufacturer's guidelines or a specialist if unsure.
Q6: What maintenance is required for a Dawei PML magnetic lifter?
A6: Dawei PML permanent magnetic lifters are virtually maintenance-free due to their design with permanent magnets. Routine checks should include: visual inspection for any damage to the housing or lifting shackle, ensuring the operating lever moves smoothly, and keeping the lifting surface clean from debris or metal chips. No demagnetization is expected, and no electrical components require servicing.
Q7: Can I lift multiple pieces of thin sheet metal with a single pml 1000 lifting magnet?
A7: It is generally not recommended to lift multiple thin sheets simultaneously with a single permanent magnetic lifter, as the magnetic field is designed to penetrate a single, sufficiently thick piece of ferrous material for optimal performance. Lifting multiple sheets can lead to insufficient magnetic grip on individual sheets, posing a significant safety risk. Specialized multi-point lifters or vacuum lifters are often better suited for handling multiple thin sheets. Always refer to the product manual and safety guidelines.
