– The new low-cost depth and slope control system from Spectra Precision
recognised that there was a need for a system like the XDS in the
construction market,” explains Peter Brooks, Spectra Precision UK
Machine Control Manager. “There are others available but they are not
so easy to use and are much more expensive – they just don’t have
the profit potential of the XDS.”
system has various operating modes including the facility to pre-set a
required depth in centimetres and then excavate until the display shows
that the bucket is at the correct depth. Alternatively, the operator can
locate the bucket at a given point first and then set that reference
into to the control unit and continue to work to it. A “keep and
save” option allows a depth reference to be carried from one work area
to another so that depth control can be maintained when excavating in
locations with differing heights. A sloped reference may also be pre-set
to assist with working to grade or to a horizontal plane.
optional boom-mounted laser “eye” receiver is available to allow the
excavator to work with a rotating laser plane for use when the
excavation level must be related to an absolute site reference. The
system simply requires the machine’s boom to pass through the laser
beam to acquire the reference.
are three shock proofed angle sensors, one on the boom, one on the
dipper arm and the other on the bucket that measure the angle of the
boom elements relative to a gravity reference. The bucket sensor is
waterproof to allow work in flooded ditches etc.
information may be viewed on both a main and a remote display unit and a
buzzer is also available for situations where the operator cannot take
his eyes off the job at all. Both visual displays show when excavating
is on-target position plus when it is lower, higher or far higher than
the programmed reference. The remote unit is mounted according to
individual preference and allows easy repositioning when operators
