Crane dampers

Crane damper for lifting and turning. It is accumulators that sit on turn and lift. Works in the same way as a load absorber on loaders for tractors. An accumulator is a container with some gas and second part oil. When you turn, some of the oil enters the accumulator due to gas being compressed but not liquid and part to the turn, until the accumulator is up in pressure, the same if you release the lever. This will give you a softer start and stop on the turn. The lift works in the same way. One more advantage with the crane damper on the lift, when you let go of the crochet, then the crane is lifted a little. Due to the stored energy in the accumulator, the wood rolls out more evenly.
