For best surface qualities and high feed speed
Feed drive system
The sash gang saw is equipped with a hydraulic feed drive with variable speed control
over the full feed speed range.
Automatic overhang adjustment
The overhang of the sash frame is automatically adjusted according to the selected
The oscillating frame of the GDZGE is characterized by the oscillation of the bottom sash
guides. The oscillation move is automatically adjusted according to the selected feed speed.
Advantage of Oscillating Frame Sash Gang
- total utilization of the sash stroke
- without rubbing
- better sawn lumber surface
- extended operating time for the saw blades
- superb smooth running
- reduced power requirement
The rollers are split and/or fitted with easily changeable inserts.
Upper sash guides
The upper sash guides are water-cooled by a cooling unit and a closed water circuit to
reduce wear and ensure a smooth running of the machine.
The lifting and lowering and the drive of the feed rollers uses hydraulic power.
The hydraulic system is composed of standard components, using a modular
principle. All parts such as electric motors, pumps and valves are grouped in a
central hydraulic system, separated from the sash gang saw and easily accessible.
The saw dust shaker and the central lubrication system have separate drives and
therefore can be used even when the machine is not running.

Two individually shifting saw banks
Optionally the sash gang is available with shifting saw banks. Each of the two saw banks
is individually adjustable. With one or more center split saws mounted, the saw patterns
can be changed from single cant to double cants or multiples without stop and changing
of spacers, saws and re-adjustment of the outfeed splitter plates. During the setting of
the saw blades in a new position, the outfeed splitter plates open automatically to release
the previous sawn log. After that, the plates move automatically in the new set position.
Optionally also available with the Vario SV4 quad width adjustment. The adjustment of the
saw banks is possible from the operator control panel during normal operation.
