Smooth transition
August 1st 2008 Stertil Stokvis has launched
a new generation of
ergonomic dock levellers:
the S series that features a
swing lip; X series, with a
telescopic lip; and P series –
a parallelogram model, with
special lip design.
All can be either pitmounted
or frame-mounted/
suspended, depending on
the application. The hinged
lip of the S series is
hydraulically extended into
position and is suitable for
most standard applications.
The telescopic lip of the X
series gives it a greater
operating range, enabling it
to accommodate many
different vehicle sizes, as
well as stepped vehicle
floors, such as in refrigerated
trucks. The telescopic lip
can bridge a vehicle tail-lift
if required and can be
infinitely adjusted to allow
unrestricted use of the full
loading area right to the
back of the vehicle.
The P series leveller has a
hinged parallelogram lip
which remains horizontal at
all times, giving an optimum
lip-to-platform angle. This
reduces impact on loading
trucks, resulting in reduced
maintenance. Impact on the
human body is lessened too.
The design is also said to
eliminate problems
associated with 'lip crown'
angles, especially when
operating below dock. More articles from Stertil UK Ltd: |
