发明名称 SHIP{40 S LOADING RAMP
摘要 A loading ramp pivotally connected to a ship comprises two unitary side beams and a travelling track carried thereby. This travelling track is composed of two parts of which an inner one extends outwards from the ship along part of the length of the beams to which it is permanently fixed. An outer part of the travelling track is hingedly connected to the inner part and is longer than the difference between the inner part and the length of the beams. The outer part is further provided with laterally extending portions upon which the ends of the beams will rest when the ramp is folded down.
