Terminal bank
A clamping bench is in the forestry used one or more tree trunks back to. A modern clamp bank consists of a cross bar with prongs and two arched clamp pliers, which can be closed by hydraulic pressure and thus clamp the tree trunk (s).
Forwarders , skidders , special forest tractors as well as other machines can be equipped with a clamp bench for the backing of usually long tree poles (long wood). When moving with a clamp bench, however, particular attention must be paid to the protection of the floor, as extremely high loads can be reached. Payloads of over 30 solid cubic meters (approx. 18 t) are possible. The amount of wood that is picked up is often over 30% higher with the clamp bench than with a forwarder, because a good third of the weight of the wood grinds on the ground. The weight of the long timber that is not lying on top must also be pulled. In addition, the resistance of the sanded wood shifts weight to the rear axle. As a result, a clamp bank transfers significantly higher forces to the ground than a forwarder while driving with loads.
