Permanent Magnet Manual Lifter
Permanent Magnet Manual Lifter: Efficient and Safe Material Handling
The Magnetic Lever Lifter is an innovative, manually controlled permanent magnet system expertly engineered for the seamless movement of ferromagnetic materials. This includes a wide array of items such as sheet metal (whether flat plates or round shapes) and various iron materials, facilitating their lifting, transportation, and precise lowering in diverse industrial settings.
This essential lifting equipment harnesses the inherent properties of powerful permanent magnets to generate a robust magnetic field. This field is precisely calibrated to attract and securely hold ferrous materials, ensuring operational efficiency and safety. At its core, the lifter is activated by a manual lever mechanism that rotates an internal assembly of high-grade neodymium magnets. Neodymium magnets are renowned for their exceptional magnetic strength, allowing the device to achieve a powerful magnetic current. During the operating phase, this magnetic current is directed through the load to be moved, effectively binding it to the lifter. Conversely, during the release phase, the lever mechanism short-circuits the magnetic field within the lifter itself, allowing for a clean and effortless detachment of the load. A significant advantage of these permanent magnet lifters is their independence from electrical power. They operate without an electronic circuit, rendering them immune to power outages and significantly enhancing safety compared to traditional electromagnetic systems.
Advanced Features and Operational Reliability
The design philosophy behind the Permanent Magnet Manual Lifter focuses on maximizing both performance and user safety. Its robust construction ensures durability even in demanding industrial environments. The integrated safety features, such as the automatic safety switch, provide an additional layer of protection, preventing accidental release during lifting operations. The careful selection of neodymium magnets ensures a high lifting capacity relative to the lifter’s size and weight, making it a powerful yet compact solution for various material handling challenges.
The absence of electrical components not only enhances safety but also reduces maintenance requirements and operational costs. Users can rely on consistent performance without the concerns associated with power supply fluctuations or electrical failures. This makes the permanent magnet lifter an ideal choice for operations where reliability and uninterrupted workflow are paramount.

- Warehousing and Logistics: For efficient loading and unloading of ferrous goods from trucks or storage racks.
- Shipbuilding and Construction: Aids in handling large steel plates and profiles with precision and safety.
These lifters are particularly valuable in any workplace that utilizes bridge cranes, gantry cranes, jib cranes, or other lifting equipment, providing a fast, reliable, and safe method for manipulating iron loads.
Working Principle and Safety Guidelines
Adhering to the correct working principle is crucial for maximizing the lifter’s efficiency and ensuring paramount safety during operations:
Prior to any lifting operation, it is imperative to thoroughly clean the surface of the ferromagnetic material. Rust, burrs, paint, oil, or any other contaminants on the sheet metal surface can significantly reduce the magnetic contact and, consequently, the actual lifting capacity. A clean, flat surface ensures maximum magnetic adhesion.
The Magnetic Lifter must always be positioned precisely in the center of gravity of the sheet metal part to be transported. This ensures balanced lifting and prevents the load from tilting or slipping during movement. Once correctly placed, lower the crane hook onto the lifting eye of the Magnetic Lifter. Then, firmly turn the operating lever from the “-” (OFF) position to the “+” (ON) position until a distinct “holding” sensation is felt and the safety switch on the handle automatically locks into place. This locking mechanism is a critical safety feature that prevents accidental disengagement of the magnet during lifting. Only after confirming the safety switch is engaged should you commence lifting the load.
Critical Safety Precautions:
- Overloading is Strictly Prohibited: Never exceed the rated lifting capacity of the Magnetic Lifter. Overloading can lead to magnet failure, load dropping, and severe accidents.
- Personnel Safety: Under no circumstances is anyone permitted to pass or work directly underneath sheets or loads held by the Magnetic Lifter. Maintain a safe distance from suspended loads.
- Temperature Limits: The temperature of the Fe content metal to be transported, as well as the ambient temperature, must remain below 80 ºC (176 ºF). Higher temperatures can demagnetize the permanent magnets over time, reducing their lifting capacity.
- Environmental Stability: The operational environment should be free from strong vibrations and impacts, as these can affect the lifter’s stability and the integrity of the magnetic hold.
- Cylindrical Parts Handling: When lifting cylindrical parts (e.g., pipes or rods), the actual lifting capacity will generally be 30-50% of the rated lifting capacity for flat materials. This reduction is due to the smaller contact area. It is crucial to ensure that the cylindrical surface makes contact with the lifter’s V-Slot along two distinct lines for maximum stability and grip. The V-slot design is specifically engineered to cradle cylindrical objects, maximizing the contact surface for a secure hold.
Upon completion of the lifting and transporting process, carefully lower the load to a stable surface. To release the load, press the lower part of the handle to disengage the safety switch from its pin. Then, turn the operating lever from the “+” (ON) position back to the “-” (OFF) position until the load is fully “Released.” The Magnetic Lifter can then be safely removed from the part surface while it is in its neutral (demagnetized) state.

An Industrial Permanent Magnet Manual Lifter is a compact, heavy-duty hoisting device suspended from a factory crane. Utilizing an internal array of ultra-strong Neodymium (NdFeB) magnets, it allows a single operator to safely lift, move, and release massive steel plates and heavy blocks by simply turning a mechanical lever (ON/OFF) without requiring any electricity.
They are mandatory safety tooling in CNC machine shops (loading heavy steel blocks onto milling tables), heavy steel fabrication yards, shipyards, mold and die workshops, and steel service centers where moving heavy steel manually causes severe back injuries.
The device contains two massive Neodymium magnet arrays: one fixed in the lower body, and one attached to the rotating rotor (the lever). When the lever is OFF, the magnetic fields cancel each other out (short-circuit internally). When the lever is turned ON, the magnetic fields align, driving a massive, deep-penetrating magnetic flux directly down into the heavy steel workpiece.
Built for brutal B2B environments, we manufacture models with Safe Working Loads (SWL) ranging from 100 kg up to massive 6,000 kg (6 Tons). For supreme safety, they are engineered with a 3:1 (or 3.5:1) Safety Factor, meaning a lifter rated for 1,000 kg actually requires 3,000 kg of pull force to break away under ideal conditions.
No, and this is their greatest advantage. They require absolutely zero electricity (100% fail-safe). If the factory loses power while a 3-ton steel block is suspended in the air, the load will never fall. The permanent Neodymium magnets will hold the load securely forever.
They are highly versatile. The bottom contact face of the lifter is precision-machined with a deep "V" groove. This allows the lifter to seat perfectly onto flat steel plates, but also securely straddle and lock onto round steel pipes, solid cylinders, and heavy shafts without rolling off.
Absolutely. Industrial safety is our priority. The manual lever features a heavy-duty, spring-loaded mechanical safety lock. Once the lever is engaged in the "ON" position, it automatically locks into a steel slot. The operator must consciously press a release button to turn the lever "OFF," preventing accidental load drops if the lever is bumped.

Factors affecting lifting capacity
The main factors affecting the lifting capacity of the Permanent Magnet Magnetic Lifter.:
- It is affected by the thickness and surface quality of the component.
- Before operation, it is necessary to find out the percentage of steel thickness-lifting capacity according to the component and capacity curve. If the surface roughness is less than Ra 6.3 um, there will be no lifter surface gap, the lifting capacity will be 100%. If the surface roughness is above or worse than Ra 6.3 um, the lifter surface clearance should be estimated. Find out the percentage that the hoisting capacity of the lifter can reach from the air gap hoisting capacity curve shown in the performance table. Combine these two factors and calculate the lifting capacity that the lifter can reach. The curves are on both sides of the lifter.
- It is affected by the composition of the steel component.
- After measurement, if the low-carbon steel component is taken as reference and the lifting capacity coefficient is fixed: the following table can be taken as a basis.
