Motors come in countless shapes, sizes, weights and designs. This makes handling a challenge. Many motor manufacturers plan threaded holes at the design stage, into which either screwable lifting points or simple eyebolts are then inserted during the manufacturing process. Other engine manufacturers provide their components with permanently welded lifting points which then remain on the engine permanently. A variant that is not yet very common is handling with so-called plug-in lifting points. When handling motors with screw-on lifting points or eyebolts, the lifting points must be screwed into the respective threaded holes by hand and checked for tightness. Depending on the number per motor, this may take some time. If the lifting point is then not to remain permanently on the motor, it must be unscrewed from the threaded hole again after the lifting process. Depending on the application, various lifting points are possible solutions.
The particular advantage of plug-in anchor points is that plug-in anchor points are not, as the name suggests, screwed in, but rather plugged in. In practice, this saves the user a considerable amount of time. Instead of a thread, this anchor point uses a threaded lifting pin. This means that the anchor point can be quickly and easily inserted into an existing, suitable threaded hole. The shape of the anchor point includes a safety device to prevent unintentional release from the load. However, it should be noted that ball suspension bolts are not suitable for continuous rotation of the load and dirt can quickly impair the function of the ball suspension bolts.
In a recent case, the customer wanted to significantly reduce the assembly time in the production of its motors for fans, while maintaining safety during the lifting process at all costs. The customer approached the Carl Stahl expert consultant with his requirements. The solution: threaded lifting pins from Erwin Halder. Depending on the application, the threaded lifting pins are available in “self-locking” and “self-locking with rotating shackle” versions.
Unfortunately not. The available load capacities are currently between 0.4 and 3 tons, depending on the version.
The slightly higher price of plug-in anchor points compared to classic eyebolts or screwable lifting points is more than compensated for by the time saved.
No, plug-in lifting points from Erwin Halder are only approved for lifting and holding individual loads. Special lifting points are available for use as fall protection in the area of PPE.
