SECTION 11.5
The lowering operation for stern ramp and side ramps are different. The height of the
stern ramp can not be adjusted, where as the height of the side ramps can be adjusted to
maintain the correct angle to the wharf in different draft and tide conditions.
11.5.2.2.1 Lowering of Stern Ramp.
Check the stopper pin of hydraulic securing cleats has been disengaged.
Check for the height and clearance between the ramp and the wharf.
Tighten the main wires on the winch.
Tighten the sub wire.
Turn the wheel and remove the manual pin.
Disengage the hydraulic securing cleats of section II and hydraulic lock of Section I.
Slack the sub wire just to remove wooden wedges. Then shift the sub wire control to
neutral.
Remove the padding wedges
Start lowering the ramp by main winch very care fully up to an angle of 25 degree to the
vertical.
The push cylinder will automatically push the ramp out.
After 25 degree angle, you have to hoist on the sub wire. Till the time the cylinder is
retracted fully.
Continue to lower the ramp with main wire.
Check the rubber mats or plywood is kept below the edge of the ramp.
Do not stop the ramps in the mid way of operations for long interval
Allow the ramp to rest slowly on the wharf over the mat.
Slacken the main wire sufficiently.
Slacken the sub wire completely
Angle of the ramp may be slightly increased by tightening on sub wire.
Lower deck flaps
Rig up the safety walkway
Do not switch off the power supply to control panel after use.
We may require adjusting the angle some times between section I and II, when the ramp
is sitting on the wharf. This may be achieved by hoisting the main wire and fixing the
angle by the wedge. Once the angle is fixed by the wedge, lower the ramp again.
11.5.2.2.2 Lowering of Side Ramp.
The side ramps are two types i.e. one with fixed height and one with adjustable height. The
operations of fixed type side ramps and adjustable type side ramps have been explained
differently.
11.5.2.2.2.1 Lowering of Fixed height Side Ramp.
The operation of this type of side ramps can be simply explained as under:
Check the stopper pin of hydraulic securing cleats has been disengaged.
Check for the height and clearance between the ramp and the wharf.
Tighten the main wires on the winch.
Turn the wheel and remove the manual pin.
Disengage the hydraulic securing cleats.
Start lowering the ramp by main winch very care fully up to an angle of 20 degree to the
vertical.
Do not stop the ramps in the mid way of operations for long interval
The push cylinder will automatically push the ramp out.
