Turning hook
The turning hook , crampon or general log turner is a tool that is mainly used in the wood processing industry for timber harvesting , and occasionally also by dock workers . It is used to move felled trunks, in particular to turn them; it is also used for the so-called chance bringing of hangers . Before there were larger machines, he also became the Roden of stumps used.
The classic reversible hook consists of a hook attached to a ring. A stable lever (often a lifting tree made of ash wood) is then inserted through this ring in order to transfer the highest possible forces. Its construction is based on the Kant ring used by carpenters . Even though machines are often used in timber harvesting today, working with the turning hook is still part of the training of forest workers .
There are different versions depending on the area of application. The approx. 2600 gram Palatinate turning hook is used for thick logs . The Black Forest reversible hook with a weight of 1600 grams has a ring with a bulge. This is therefore adjustable in size and has a wider range of applications. The versions, which weigh around 800 grams, are lighter, such as the Baak reversible hook or the Orter reversible hook, and are mainly used for medium-thick wood. Even lighter versions can do without the ring; here the hook is attached to a handle like a joint, as is the case with the felling lifter .
The phrase has literally emerged: “have someone on the crampon”, that means: “don't let someone slip away”.
