Abstract

pile driving installation, comprising: a hydraulic cylinder (7) for driving the falling weight, a control unit (6) arranged in the vicinity of the cylinder, a pump (17) connected to the control unit via a pressure conduit (15), and a reservoir (21) connected to the control unit via a pressureless conduit (16), wherein the control unit is arranged such that when pressure is applied to the pressure conduit, the pressure in the pressure conduit lifts the weight and when pressure in the pressure conduit falls away the falling weight moves downward. Because the control unit present at the top of the piling frame thus reacts directly to the pressure in the pressure conduit, the pile-driving process can be controlled from below without transferring signals via extra means for signal transmission such as electrical cables. The above steps further avoid the use of electrically operated valves at the top of the piling frame. This would in any case also very quickly lead to breakdowns. The invention allows the two conduits necessary for supplying energy, in this case the hydraulic pressure, to be used as signal transmission lines. According to a preferred embodiment the control unit comprises a valve (24) connected to the lifting side of the cylinder, which valve is closed when pressure is applied to the pressure conduit and which opens when the pressure in the pressure conduit falls away. <IMAGE>
