ORFS-design.
Toplift attachment
The primary function of the attachment is to firmly attach
the container during lifting. This is done with four
twistlocks which rotate, thereby securely gripping the
container’s corner fittings. The mechanical levelling
ensures that the twistlocks reach the corners, even if the
container is leaning. The attachment can easily be
adapted to different container standards. A hydraulic
motor drives the function via chains. The container can
also be moved sideways to facilitate loading and
unloading, or to compensate for unbalanced loads. Two
hydraulic cylinders perform the side-shift movement.
The DRT reachstacker is available with a
variety of drive trains and optional equipment
to fulfil demands of customers worldwide.
