Magnetic Lifters

Dailymag Company's Permanent magnetic lifter has strong magnetic path produced by NdFeB magnet. On and off of the magnetic path is controlled by turning the manual handle. The magnetic lifters have the features of strong attraction, smaller volume , lighter weight, powerful lifting effort , easy and safe to operate, long-period effort and without power supply. Magnetic lifters are been used to lift and transport the steel and iron for factories, docks, ware houses, transportation etc.

1. Universal Magnetic Lifters   (Magnetic Lifter, Permanent Magnetic Lifters)

1. The safe coefficient of magnet lifter is 3.5
2. Dimension can be changed if client requiring.
3. PML-60 can be made according to customers' requirements.

2. Two-magnetic circuit Magnetic lifters   (Magnetic Lifter, Permanent Magnetic Lifters)

Compared with universal magnetic lifters, two-magnetic circuit magnetic lifters adopt Two-Magnetic Cycle Technology that can obtain more uniform output of magnetic force. When you lifter steel sheet or other ferrite material with rough surface, it is very easy to operate the handle, you can use very light force to roll the handle for opening or closing and let your work very safe and convenient. 

It is new design, and we can manufacture lifting magnets according to customers requirement.

The safe coefficient of magnet lifter is > 3.0

3. Super Magnetic lifters (Magnetic Lifter, Permanent Magnetic Lifters)

Dailymag manufacture super 300KGF, 600KGF, 1000KGF, 1500KGF, 2000KGF Magnetic lifters for worldwide customers.

This type of Magnetic Lifters have very good quality and nice appearance, and the price is a little higher than universal type.
The safe coefficient of magnet lifter is 3.5

How to distinguish between high-quality permanent magnet lifter and inferior permanent magnet lifter?

The core component of the permanent magnet lifter is Neodymium magnet. Neodymium belongs to rare earth metal. The mining rights of rare earths are now controlled by state-owned enterprises, with Minmetals Rare Earths in the south and Baosteel Rare Earths in the north in China. And a few part circulating material on the market are sludge produced by machining in processing plants.

It looks same magnet with similar magnetic force. Why there are some magnetic lifers the magnetic force decays significantly after used for a period like 2-3 months? or even 1 month?

Because in inferior producer, their neodymium magnets are doped with other cheap materials, non-rare metals, the Hcj value of the neodymium is very poor, much lower than the standard value, they can maintain the Gaussian value in a short time, but after two or three months, the magnetic force will be unstable and begin to attenuate. 

The product will be NOT as good as before after one year. At that time, users can just feel the difference between the products of good suppliers and those of inferior suppliers.

You can investigate whether your friend or colleague who have purchased cheap lifters and whether they have similar experience.

Of course, using lower grade Carbon steel materials for the hardware shell of the lifter is also a way to reduce cost.

Dailymag magnetic lifters could used for 5+ years under 60 degrees Celsius(Normal grade neodymium magnets are 80 degrees Celsius temperature resistant), you can also check with customers who have purchased Dailymag magnetic lifters, if the units still working well, if the customers are very satisfied with Dailymag products.

Dailymag guarantee that our magnetic lifters use Top grade N52 Neodymium magnets, Intrinsic Coercive Force Hcj value≥ 876kA/m (≥11kOe). Magnetic safety factor is 3.5 times as marked. 3.5 times is International standard requirements.

How to choose a permanent magnet lifter which could meet your budget？

First of all, determine the magnetic force requirements of your working environment, the price of different magnetic capacity magnetic lifters have big difference, product price is proportional to the nominal magnetic force. If you often lift cylindrical steel pipes, usually around 1000kg, then you should choose PML-10 1000kg model. If you basically lift square billets, then you choose PML-6 600kg model is enough, because the Dailymag magnetic lifter has 3.5 times safety factor, it can pull up a flat square billet weight 600x3.5=2100kg.

In addition, for loose parts, you can choose the most suitable model magnetic lifter according to the weight of the iron parts you will probably handle at one time.

Secondly, If you still have limited product cost tolerance, you can request to reduce the product's magnetic safety factor to 3.0 or 2.8, and the product can still work safely in most work environments. In this way, we can reduce the size of the assembled magnet and reduce the product cost to reach your budget.
