To provide a lift device for a motor truck which enables a table to be turned into a horizontal state in response to inclination of the table caused by a situation of a road surface and a vehicle attitude.SOLUTION: In a lift device for a motor truck, a loading platform 1 is mounted at a rear part of the motor truck, and a parallel linkage 5 is pivotally mounted on a main frame 4 laterally installed on an underfloor space of the loading platform 1. A table 3 is pivotally mounted on a tip of the parallel linkage 5. Further, a lifting cylinder 40 which rotates the parallel linkage 5 and a rising/falling cylinder 7 which rises and falls the table 3 are provided. The lift device for the motor truck is provided with: detection means 50 which detects an attitude of the table 3; and control means 55 which turns the table 3 into a horizontal state based on a signal from the detection means 50 when the table 3 is inclined. Enabling the table 3 to be lifted in a horizontal state allows the table 3 to be turned into the horizontal state regardless of a situation of a road surface and a vehicle attitude.SELECTED DRAWING: Figure 2
【課題】路面状況や車両姿勢によるテーブルの傾斜に対応して、テーブルを水平状態とすることができる貨物自動車用リフト装置を提供する。【解決手段】貨物自動車の後部に荷台1を搭載し、この荷台1の床下に横設したメインフレーム4に平行リンク機構5を枢着し、その平行リンク機構5の先端にテーブル3を回動自在に枢着するとともに、平行リンク機構5を回動させる昇降用シリンダ40と、テーブル3を起伏させる起伏用シリンダ7とを設けた貨物自動車用リフト装置において、テーブル3の姿勢を検知する検知手段50と、テーブル3の傾斜時に検知手段50からの信号に基づきテーブル3を水平状態とする制御手段55を設け、テーブル3を水平状態で昇降可能とすることで、路面状況や車両姿勢とは関係なく、テーブル3を水平状態とすることができる。【選択図】図2
