But they are! You can find lifting magnets based on permanent magnets all over in machine shops.
To lift a heavy load from the floor, start by bending your knees and keeping your back straight to avoid strain. Grasp the object with a secure grip, engage your core muscles, and lift with your legs rather than your back to reduce the risk of injury. Make sure to use proper lifting techniques and, if needed, ask for help if the load is too heavy for you to lift alone.
Using tools such as levers, pulleys, or hydraulic systems can help people lift heavy objects with less force by multiplying the input force exerted. These mechanisms allow for a distribution of the load over a larger area, making it easier for individuals to lift heavy objects.
A wheelbarrow uses a lever to lift a load. The handles act as the effort arm, while the wheel and the load act as the resistance arm, allowing the user to easily move heavy items by leveraging the load against the wheel.
In a class 2 lever, the effort required to lift a load is greater than the weight of the load because the load is between the fulcrum and the effort. This means the effort arm is longer than the load arm, which increases the mechanical advantage of the lever, making it easier to lift heavy loads.
The load arm of a lever is the distance between the fulcrum (pivot point) and the point where the load or resistance is applied. It determines how effectively a lever can lift or move a load. A longer load arm typically results in a greater mechanical advantage, making it easier to lift heavy objects.
They can become demagnetized by impact, if they're picking up something which is also magnetic (which steel is), the magnet would need to be changed when the polarity was wrong, and then there's the matter of how you detach the magnet once you got the load into place.
A lever
The fulcrum should be placed closer to the heavy load to balance it. By positioning the fulcrum nearer to the heavy load, more leverage can be generated to lift the load with less effort.
you get it up to operating speed and see if it delivers full load voltage and current. if it has been severely overloaded the permanent magnet can be discharged causing the output to be low

an inclined olane allows you to lift a heavy load by using greater force over a shorter distance
more than force muscles fibres inside the body are mainly responsible for lifting heavy load.force comes from them to lift the heavy load.

If it's possible, get help from another person or two; don't do it yourself. If it's so heavy you can't even lift it, consider a fork lift or something.
