Swing-Rotator-Grapple for skidders

What are the requirements involved in skidding?

Skidders with crane can handle both short and long timber. A particular challenge here is posed by long timber. When skidding, the machines generate high traction forces, and the load transported in the grapple heavy shocks.

What is the ideal combination of brake link, rotator, and timber grapple?

1. It is very important that skidders are fitted with a HULTDINS crane suspension. This relieves the peak loads on the crane and machine and the strain on the driver.

2. While the forces raising the timber grapple on the truck crane or forwarder are predominantly vertical, the traction forces generated by the skidder induce considerable transverse and lever forces. The timber grapples must be built far more solidly at the claws and in the top section. The best solutions here are the HULTDINS SuperGrip I-S-VM and SuperGrip I-RS series.

3. A double braked swing link (braked in both directions in direction of the crane and sideways) serves to reduce the disruptive swinging motion of the timber grapple when travelling empty. We are sure INDEXATOR MPB is the best solution on the market.

4. The S and G versions of the Indexator rotators are particularly ideal for these large traction forces and heavy shocks.
