Abstract: Pump assembly for the lift cylinder of a hand fork-lift truck includes a piston pump activated by a bar of a hand fork-lift truck and has a piston chamber and an annulus collector. A three stage control valve connects the lift cylinder with a tank in the lowered setting and connects the piston chamber with the tank in a neutral setting and in a pump setting, connects the piston chamber with the lift cylinder through a first check-valve, with the tank through a second check-valve, a third check-valve between the piston chamber and the annulus collector open to the piston chamber, and a reversing valve between the piston chamber and the annulus collector.

Abstract: A tiller for a pedestrian-controlled fork-lift truck, comprising a hollow tiller rod which has its lower end hinged to a support for a steerable wheel and has its other end connected to a loop-shaped handle which, at the rear end, has a gripping portion extending crosswise to the tiller rod, a retaining extension extending into the interior of the handle as an elongation of the tiller rod, a handle means pivotally supported by the retaining extension which is coupled to a lifting means via a pusher or puller element within the tiller rod, wherein the handle means having an intermediate neutral pivoting position and two opposed pivoting positions in which it actuates the lifting means for a lifting or lowering operation, characterized in that the handle means is a loop-shaped elongated gripping element including two approximately parallel extending long element portions which extend crosswise to the tiller axis, and two curved, short element portions (interconnecting the long element portions which are located
