LARGE PERMANENT MAGNETIC LIFMA [Model LPH]
Permanent magnetic Lifma with smooth operation and enhanced safety realized by pursuing the optimum magnetic circuit to the limit.
[Application]
Permanent magnetic type lifting magnets used as a lifting section of cranes and hoists for transportation of steel materials in warehouses and machining shops or for loading and unloading workpieces to and from machine tools.
These are suitable for transporting semi-finished products having a flat surface such as machine parts, press dies and plastic molds and for transporting mill scale steel plates and flat steel materials.
[Features]
-
All types are capable of lifting steel plates and round steel bars.
-
The ON/OFF handle operating force has been reduced to a half max. of that of the conventional models. The operability in lifting thin workpieces and pipes that are difficult to lift with conventional models has been improved. (Patented)
-
In addition to the conventional handle lock mechanism, a safety stopper is provided as a standard accessory. These double safety measures prevent falling of lifted objects due to unexpected returning of the handle. (Design registered)
-
These are of permanent magnetic type requiring no power source. Thus, there is no risk of falling workpieces due to power failure or failure of wiring systems.

*If plates are thinner,the handle operation becomes harder. The handle operation also becomes harder when there is clearance. The return of the handle at the time of OFF operation becomes faster. |

･The capacity varies depending on the wall thickness of pipes. If pipes are oval or curved, lifting them, even if they are short, is risky. In the case of pipes, the handle operation is harder than when handling steel plates.
･In the case of pipes of thin wall thickness, the handle operation becomes difficult. The return of the handle at the time of OFF operation becomes faster.
･The lifting capacity varies depending on the diameters of round steel bars. When workpieces are longer than 3m, it is very dangerous to lift them with one unit of the Lifma since they cannot be held in balance. For long workpieces, consider the use of several beams.
※Keep in mind that the capacity drops when lifting pipes or workpieces the max. diameter of which is smaller than the attractive face or workpieces the max. diameter of which is shorter than the lifting standard length(LPH-2000). |
