The car decks of passenger car ferries are usually loaded through large stern and bow gates. The advantage of this vessel type is quick and easy loading and unloading. There is a ramp in the port for cargo handling, along which vehicles can move to and from the ship.
WE MANUFACTURE CUSTOMIZED CAR RAMPS FOR DIFFERENT APPLICATIONS
The side car ramp can be implemented for passenger cars and vans entering and leaving the ship. The side car ramp connects the port and the ship’s upper car deck. The ramp is designed for light car traffic.
The side car ramp consists of a fixed part and a hydraulically movable upper platform. The parts are connected to each other by a hinged flap.
The moving part of the ramp is controlled either by a control panel placed on the base of the car ramp or by a separate controller. The lifting and lowering of the moving part of the side car ramp takes place by means of lifting cylinders. The longitudinal movements of the vessel are compensated by a wheel beam system located at the end of the moving ramp.
RoRo (Roll-on/Roll-off) car ramps are an adjustable ramp along which cars are driven to the ship through the bow or stern gate. If the ramp is used only in connection with the ship’s stern gate, it is called the stern ramp. The RoRo car ramp is hinged and the hinges are attached to the ground end of the ramp. The height adjustment of the steel flap is done hydraulically with telescopic cylinders and controlled manually from the dock control panel. For smaller stern ramps, the height can also be adjusted using lifting screws.
The RoRo car ramp is locked in its operating position with locking pins, each controlled by its own hydraulic cylinder. In the stern ramp, the locking of the operating position is managed by a locking tower with several different positions as required. An automatic limit switch controls the positions of the steel flap & locking pins and ensures the safe operation of the RoRo and stern ramps in all situations.
The double ramp has separate lower and upper parts that are hydraulically adjusted. The type of ship, the weight of the cargo and the variation of the water level affect the height adjustments of the ramp. The double ramp may also have a separate drop-down section to be used if the ship enters the port bow first. The lower ramp is adjusted by means of hydraulic lifting cylinders whenever the ship’s draft changes. Ramp raising / lowering and automatic travel controls are also equipped with manual controls to ensure operational reliability in all conditions.
The upper ramp consists of a fixed ramp part, an adjustable base part and a lifting flap with a tip flap. The fixed ramp section leads to an upper ramp, the adjustable ramp of which is supported by hinges on the fixed ramp section. The adjustable ramp on the sea side is adjusted / raised with hydraulic cylinders. Lifting the tip flap to the bow of the vessel is done with two double-acting hydraulic cylinders. In this case, the hydraulics are in the float mode, i.e., the lifting flap follows the varying height of the vessel each time it is loaded or unloaded. The hydraulics room controls both the lower and upper ramp functions. For example, upper ramp height adjustment, tip lift, lateral ramp offset, and lower ramp adjustments and positions.
We manufacture and deliver car ramps either on the basis of the customer’s own design plans or the customer’s initial data. For total deliveries, we are responsible for design, manufacture, installation, user training and maintenance. We have extensive experience in the requirements, standards and deliveries of reliable and safe port facilities. The car ramps are pre-welded assemblies, and the elements ready for installation are connected to each other with bolted joints. Car ramps with bolted joints guarantee quick on-site installation and reduce welding work at the installation site.
The steel surface parts of the ramps are equipped with anti-slip features that are highly resistant to mechanical wear and varying weather conditions. Outdoor lighting fittings are frost-resistant LED luminaires suitable for port conditions. Depending on the size and purpose of the ramp, they are often also equipped with traffic lights and booms.
Each delivery is its own project, where the best and most appropriate structural solution is determined together with the customer. Seawater-resistant aluminum and stainless-steel structures in particular are highly resistant to corrosion even in challenging conditions. The corrosion resistance class of the ramps is M5. We supply car ramps with CE marking in accordance with the Machinery Directive 2006/42 / EG and in addition they are manufactured in accordance with the regulations for load-bearing structures EXC2. The loads calculated for the structures and the design of the steel structures meet the strict requirements of Eurocodes 1 and 3.
