Flat locating bushes of the Erwin Halder KG
All lifting pins made by Erwin Halder KG are composed of a bolt with a movable shackle. The balls located on the lower end of the pin lock into place automatically, thus securing the lifting element. For unlocking, an aluminium push-button is integrated below the shackle. A locking stud safeguards against unintentional unlocking.
“All the user needs to do in order to use the lifting pins is to insert the pin into the ready-made hole – or into one of our locating bushes. They hold the loading-handling devices securely in place even if the material of the component to be lifted is soft such as, for instance, aluminium. Thus, our tools allow for the application of significantly higher forces”, explains Bernd Janner, Sales Executive at Erwin Halder KG.
Flat surface without interfering contours
However, there are countless applications where locating bushes jutting out from the components are undesirable or even interfere with the seamless use of the components. Examples of such scenarios are house fronts, mobile base plates such as those used in stage construction, and fixtures. Erwin Halder KG has devised locating bushes that suit these applications perfectly. When screwed into the component, they do not create any interfering contours and afford the user a flat surface.
The flat locating bushes are made of precipitation hardened stainless steel 1.4542. This makes them exceedingly resistant to corrosion and wear. They are also available from stock with inner diameters in grades from 8 to 20 mm. The thread diameter ranges from M16 to M36 depending on the model used. The locating bushes are suitable for lifting pins with nominal lengths ranging from 10 to 75 mm.
Installation is quick and easy
If using our optional tools, the user can install the bush reliably and with ease into various supporting materials including thin-walled parts. The tools come in two different models. Available in two different versions, the adjustable face wrench makes screwing in all flat bushes quick and easy. If, however, installation space is limited, preventing circular turns of the adjustable face wrench, the best tool to use is the face and socket wrench. It can be used in combination with a ratchet or a torque wrench. The four sizes Halder offers cover all diameters of the locating bushes.
