PRP-58, PRP-58W

Product catalog summary

Overview: The PRP-58 and PRP-58W are advanced saw machines designed for cutting logs of various lengths and diameters. The PRP-58 can handle logs up to 350 mm in diameter, while the PRP-58W can accommodate logs up to 430 mm due to its larger vertical clearance between rollers.

Horizontal Clearance: 580 mm for both models.
Vertical Clearance: 350 mm for PRP-58 and 430 mm for PRP-58W.
Saw Frame Stroke: 300 mm for both models.
Main Shaft Rotational Speed: 330 r.p.m. for PRP-58 and 300 r.p.m. for PRP-58W.
Working Feed Rate: 0.5 - 2.5 m/min for both models.
Blade Dimensions: PRP-58 uses 815 x 70 x 1.6 mm blades, while PRP-58W uses 915 x 80 x 2.0 mm blades.
Maximum Number of Blades: 12 for PRP-58 and 10 for PRP-58W.
Main Motor Power: 15 kW/400V (or 11 kW) for PRP-58 and 15.0 kW/400V (or 18.5 kW) for PRP-58W.
Feed Motor: 0.75 kW/400V for both models.
Hydraulic and Lubricating Pump Motors: 0.75 kW/400V and 0.18 kW respectively for both models.
Minimum Sawing Thickness: 13 mm for PRP-58 and 9 mm with special blade adaptors for PRP-58W.
Minimum Log Length: 1.8 m, or 1.2 m with optional equipment for both models.
Overall Dimensions: PRP-58 is 1.20 x 1.70 x 2.10 m, and PRP-58W is 1.20 x 1.70 x 2.20 m.
Net Weight: 3200 kg for PRP-58 and 3450 kg for PRP-58W.

Innovations and Features: The PRP-58 series incorporates several technical innovations, including dynamic blade stress management, openwork saw blade construction, and devices for quick feeding of short logs. The feeding truck construction has been updated for enhanced performance with both long and short logs.

Applications: The PRP-58 functions as a traditional saw, multiple-saw, and circular saw for pallets, characterized by a minimal saw cut, making it versatile for various sawing needs.

DROZDOWSKIZaktad Metalowy www.drozdowski.com.plPRP-58, PRP-58W PRP-58 saws the logs of each length and diameter up to 350 mm. Thanks to bigger vertical clearance between the rollers, version PRP-58W may cut diameter up to 430 mm The frame horizontal clearance of 580 mm makes it possible to cut a very thick log after one- or two side cutting off in the band saw. Several technical innovations is used in PRP-58 machine. Among others: the dynamic stress of blades, special openwork construction of saw blades, device for short logs inserting and set for their quick feeding. The construction of the feeding trucks has been completely changed with reference to those traditional ones. They may be used for the long and short logs after minimal reinforcement. The PRP-58 machine functions as a traditional saw, multiple-saw and circular saw for pallets. It is characterized by a very small saw cut.
