600 and 700 Stroke Oscillating Frame Sash Gang
For highest requirements
Feed drive system
The sash gang saw is equipped with a hydraulic feed drive with variable speed control
over the full speed range. In combination with the automatic overhang adjustment the
feed speed for an optimum relation between saw speed and relative feed speed is
achieved. The rubbing of the saw blades is eliminated as much as possible which results
in a good lumber surface quality.
Automatic overhang adjustment
The overhang of the sash frame is automatically adjusted according to the selected feed
speed. Maintenance free spindles and worm gears adjust the overhang plates.
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.
Besides the model with 4 feed rollers a model with 6 or 8 feed rollers is available.
The sash gang HDSN can be placed on the foundation of the models HD30 and EHD30.
Up to 110 kW drive motors, the sash gang HDSN is fitted with fix and idle pulleys for
shifting of the drive belt. For bigger drive motors (up to 160 kW) the sash gang saw is
fitted with an enlarged fix pulley for direct drive.
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 drive systems
and therefore can be used even when the machine is not running.
Hydraulic shifting saw banks
Optionally the sash gang HDSN is available with a symmetric hydraulic shifting saw
bank system „SV“. Optionally also available with the Vario SV4 quad width adjustment.
The adjustment of the saw banks is possible from the operator control panel during
