Trailer-mounted log loader FB84DT

tractor-mountedknuckle boom

The Crane FB84DT is the largest and most powerful forestry crane in the FB series, designed for high lifting capacity, optimized motion paths, and a maximal reach of 8.4 meters, making it an agile and productive loader for forestry operations. Its construction is based on heavy-duty professional cranes, ensuring extraordinary durability and reliability for forest work, while minimizing maintenance costs. Forestry cranes like the FB84DT are typically used with timber trailers but can also be mounted on tractors using a 3-Point attachment, or used with wood chippers and splitters, providing a safe and efficient way to handle materials. All Källefall cranes are prepared for winch installation, extending the working range and facilitating the collection of single logs.
