Abstract
The present specification describes a boarding ramp which, in use, is pivotally secured to a waterborne craft said boarding ramp comprising an elongate passageway. One end region of the passageway is pivotally attached to a waterborne craft, and a hydraulic ram is connected to the passageway and to the craft. In use, the ram controls pivotal movement of the passageway, and a magnet is arranged on the other end region of the passageway for use in securing the said other end region of the passageway to an unloading location.
Claims11
A boarding ramp which, in use, is pivotally secured to a waterborne craft, said boarding ramp comprising an elongated passageway, one end region of which is adapted to be pivotally attached to the waterborne craft, a hydraulic ram being connected to the passageway and connectable to the craft to, in use, control pivotal movement of the passageway, a controllable bypass connected across the hydraulic ram, a solenoid valve disposed and operative for controlling said controllable bypass, and an electromagnet being arranged on the other end region of the passageway for use in securing said other end region of the passageway to an unloading location.
A boarding ramp which, in use, is pivotally secured to a waterborne craft, said boarding ramp comprising an elongated passageway, one end in the region of which is adapted to be pivotally attached to the waterborne craft, a hydraulic ram connected to the passageway and connectable to the craft to, in use, control pivotal movement of the passageway, a controllable bypass connected across the hydraulic ram, a solenoid valve disposed and operative for controlling said controllable bypass, and a remotely controlled electromagnet arranged on the other end region of the passageway for use in securing the other end region of the passageway to an unloading location, wherein the controllable bypass is coupled to the electromagnet so that when the electromagnet has been energised the bypass is opened.
