Ladders for loading and unloading of cargo vehicles
A ladder for loading and unloading a cargo vehicle according to the present invention comprises: a ladder frame having one side installed on a cargo vehicle and forming an incline with the ground; and an anti-slip plate installed on the ladder frame at a predetermined interval to form an inclined surface; wherein the anti-slip plate is formed by being bent in the longitudinal direction and comprises: raised parts having smooth surfaces; an inlet part formed between the raised parts; and first and second support parts bent downward along the longitudinal direction at both extreme ends. On the smooth surface of each raised part, a friction protrusion part is formed by burring upward from the inner surface. Discharge holes are formed in the inlet part at predetermined intervals. Accordingly, the ladder can help improve productivity.
본 발명에 따른 화물차량의 상,하차용 사다리는 화물차량에 일측이 설치되어 지면과 경사를 이루는 사다리프레임과, 상기 사다리프레임에 소정의 간격을 설치되어 경사면을 형성하는 미끄럼방지플레이트를 구비하며, 상기 미끄럼방지플레이트는 길이 방향으로 절곡되어 형성되는 것으로, 평활면을 가지는 융기부들과, 융기부들의 사이에 형성되는 인입된 인입부와, 양측가장지리에 길이 방향을 따라 하방으로 절곡된 제1,2지지부를 구비하며, 각 융기부의 평활면에는 내면으로부터 상방향으로 버링되어 마찰돌기부가 형성되고, 상기 인입부에는 일정간격을 배출공이 형성된다.
