Together with its range of accessories, Hultdins patented
6XSHU&XW saw unit is a comprehensive
alternative for all applications with demands on
functionality, reliability, service-friendliness, economy
and the environment.
6XSHU&XW is a complete unit with
integrated feed cylinder, well protected from external
damage. It has been designed for use with hydraulic
motors of the type VOAC F11 - 10 or, alternatively, F11 -
19. The saw motor bracket is assembled in ballbearings in
the saw unit so that the hydraulic motor is stationary when
the saw is fed out. The saw bar is returned either
pneumatically by an accumulator or hydraulically with oil.
In its standard version, the
6XSHU&XW is
equipped with automatic hydraulic chain tensioning and
cam controlled mechanical lubrication pump that
distributes lubricant to the chain during the complete
sawing operation.
The mechanical lubrication pump delivers a maximum
volume of 6 ml and the process can easily be adapted to
specific lubricating requirements with a number of
different cams. All the lubrication oils found on the market
can be used.
All this in combination gives good saw bar, chain and oil
economy.
With the accessories that are available for the
6XSHU&XW

, you can easily design an integrated
unit consisting of the saw unit, cam, saw motor, saw motor
manifold, pressure regulating valve kit and drive sprocket
kits.
Air and lubrication oil tanks are available as extra
accessories and the
6XSHU&XW can be
equipped with a saw home detector sensor and a cut
control kit as options. The cut control kit is used in
combination with a computerized bucking device and
limits the angle to which the saw bar is fed out in
relationship to the diameter of the tree.
