The quarter ramp/door consists of three parts

main section, folding section, and flap. The cylinder installed between the primary and folding sections adjusts the ramp tilt angle according to the quay height.
This has been designed in a structure to fully satisfy heavy loading strength and accommodate the balance and slope of the vessel.
They are not limited to the quay wall strength conditions by reducing the pressure on the pier through an auto-tension function.
The system is generally operated and controlled through the PLC program, and various operation methods are available according to customer requests.

– main ramp and flap.

or upwards.

Door are used for PCTC.

They are used simultaneously or alternately for fast loading/ unloading of thousands of vehicles.
