BELT DOORS FOR SELF UNLOADING VESSELS
design has three door panels in one. The door panel
is located between the conveyor belts and rotates parallel
within the frame when closed and 90 degrees perpendicular
with the frame when open. When the panel is rotated
in the closed position it has two wedging panels that
expand at the top and bottom to seal against the bottom
of the carrying belt and the top of the return belt.
The rotating panel is attached to the frame by two
keyed shafts that the panel rotates on.
open the door panel rotates parallel to the deck and
is between the two conveyor belts preventing the belts
from any contact with the panel, which would cause belt
wear. The door is rotated by hydraulic cylinders that
are connected to a rotating door lever at one end and
the front face of the frame on the other end. When the
rotating panel is closed to the vertical position the
carrying belt will now be flat instead of dished. This
procedure does not take up belt slack between bulkheads
that requires excessive hydraulic pressure increasing
with every bulkhead door being closed. When the door
is in the vertical position the expansion wedge plates
can be extended to form a watertight seal on the belt
surfaces. These expansion plates are located both at
the top and bottom of the rotating panel. The expansion
plates are guided and held in place with adjustable wedge
plates. Attached to each expansion plate are hydraulic
cylinders. When they are energized the rods extend forcing
the two expansion wedge plates to extend. When
this procedure is complete the belt plugs are extended
to the sides of the conveyor belts completing the watertight
integrity of the bulkhead opening.
design is supplied with a local modular control plate. This
plate has the door controls mounted, pre-wired and pre-piped
making it very easy to install. The door and frame assembly
is complete with pre-mounted hydraulic cylinders that are
pre-piped making it one modular assembly. Our modular design
makes it installation and maintenance friendly.
The doors are custom designed to each conveyor system. We have 28 years of experience
in this field, worldwide and have certifications from all of the major Regulatory
