PRP-58, PRP-58W
PRP-58 cuts logs of any length and diameter up to 350 mm. The PRP-58W saw, thanks to increasing the vertical clearance between the rollers to 430 mm, can cut thicker logs.
The horizontal frame clearance of 580 mm enables cutting even very thick logs in the case of prior, one or two-sided cutting on a band sawmill. Many technical innovations have been applied in the saw, including: dynamic tension of the blades, a special openwork construction of the saws, a device for introducing short logs (meters), and a set for their quick feeding.
The structure of the feeding trolleys has also been completely changed in relation to the traditional ones. They can be used with minimal conversion to long and short wood.
PRP-58 and PRP-58W, apart from the function of a traditional sawmill, successfully performs the role of a multi-rip saw, a disc saw for a “pallet machine”, and in all applications it is characterized by a very small kerf.
