Abstract

A hand trolley, with a hydraulic cylinder to raise and lower the load carrying platform, has a pump which supplies the cylinder and which is in the bottom of the vertical hollow control shaft with the fluid reservoir and the distributor valve. A control trigger for the valve is mounted inside the handle at the top of the shaft and is connected to the valve by a rod passing down through the hollow handle, which itself forms the reservoir. This valve has two side by side spring loaded valve balls which are moved alternately from their seatings by a spring loaded forked member attached to the bottom of this rod.
