500 Stroke Oscillating Frame Sash Gang

Cost-efficient sash gang for the use in medium-sized sawmills

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 feed
speed. Maintenance free spindles and worm gears adjust the overhang plates.


Oscillating frame

The HDE-S is fitted with an oscillating frame. The combination with the automatic over-
hang adjustment achieves very advantageous sawing conditions, without rubbing of the
saw blades. The ejection of saw dust to the top is eliminated as far as possible and the
sawing of large logs is made considerably easier.



The hardened rollers are split and easily changeable. Besides the model with 4 feed rollers
a model with 8 feed rollers for the sawing of short logs (min. 1 m) or for curve sawing is



The sash gang HDE-S can be fitted on the foundation of the models S71 / SS71.


Main drive
The sash gang saw is fitted with fix and idle pulleys for the shifting of the drive belt.


Hydraulic system

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.


Hydraulic shifting saw banks

Optionally the sash gang HDE-S is available with a symmetric hydraulic shifting saw
bank system „SV“. The adjustment of the saw banks is possible from the operator
control panel during normal operation.
