2.JPG
OTL 54-50 crane has been designed for performing technological works on forest areas during loading and unloading timber on forwarding and transportation vehicles.
The crane is adapted to:
- attachment to an assembly plate of a loader or stabilizers improving stability of the set during work,
- work with tractors equipped with external hydraulic connectors or other system of hydraulic supply of specific parameters.
OTL 54-50 crane is to be mounted on trailers of 7000 kg payload. The construction of the trailer should provide a proper strength together with stabilizers – should provide stability during work.
The crane is for performing forestry (or agricultural) works. It is equipped with a timber grapple. It can be intended for ordinary loading and unloading works and it is forbidden to assemble a lifting hook at the end of the crane's arm.
