New technology, such as intelligent steering and sensors, has been included in the development of these forestry cranes.
Cranab has focussed on functionality, ergonomics and service-friendliness. Increased use of sensors will take place in the slewing motor, main boom, outer boom and telescopic boom. The first cranes to be launched will be the medium sized range of forwarder cranes (FC 6, FC 8, FC 10, and FC 12). These cranes are currently undergoing field tests and will be mass produced from 2012. The world premier of these cranes will take place at Skogsnolia 2011. Some of the key new components of these cranes are as follows:
-
Crane pillar and main boom – The crane pillar is angled backwards and the main boom has been extended. The crane does therefore not end up in the top position as often when working at close range, requiring less of the operator’s attention. Lifting and loading capacity is improved when working with branches, tops and brush. The new geometry also makes it easier to load directly against the gate of the forwarder and achieve better load distribution.
-
New brake solutions – The solution consists of a double brake at the crane nose that can be used during active braking. Continuous work becomes easier as the grapple is better controlled. When the crane swings, the pressure in the slewing cylinder is used and transferred to the brake, which is activated.
-
Hose routing protection – The hydraulic pipes and hoses have been routed together in a protected location at the crane nose. The routing passes through the link to the rotator. The cranes will have two extra hydraulic lines routed to the crane nose, with one being used for the active brake.
-
Service friendliness – These include individual tensioning of hoses in the telescopic boom, more powerful chains in the chain mountings, soft-sealing hydraulic couplings, as well as lateral slide blocks on the intermediate boom which can be adjusted from the outside.
