  • Patent number: 3940338
    Abstract: A pallet truck is provided with a tiller and a lift device including a lift jack. This is pumped by means of the tiller. In the upper part of this tiller is pivotally mounted a control lever for controlling the lift device for its functioning in different ways. For this purpose the lever is adjustable into three different positions, two outer ones and a middle one, and is by means of a link rod connected to the lift device. The link rod is spring loaded in such a way that it tends to move the lever from one outer position to the other outer position. One outer position is a pumping position for raising the jack. The other outer position is a release position for lowering the jack; while the middle position is a neutral position.
