Abstract: The invention relates to a pneumatic hoist and a method for capturing and storing operating states and operating parameters of a pneumatic hoist. In order to provide a pneumatic hoist and a method for capturing and storing operating states and operating parameters of a pneumatic hoist, which allow operating states and operating parameters of the hoist to be reliably determined with a high degree of accuracy in a structurally simple manner, it is provided that the pneumatic hoist comprises a pneumatic motor for lifting and lowering a load, a first fluid inlet of the motor for lifting the load, a second fluid inlet of the motor for lowering the load and a fluid outlet exiting the motor, wherein at least one, preferably two pressure sensors are arranged in the region of the first and/or the second fluid inlet and at least one further pressure sensor is arranged in the region of the fluid outlet.

Abstract: The invention relates to a handheld controller for the indirect control of a fluid-operated hoist with at least one control fluid inlet and at least one control fluid outlet, a control valve arranged between the control fluid inlet and the control fluid outlet and a control element for actuating the control valve by a user. In order to provide a handheld controller for indirect control of a fluid-operated hoist and a fluid-operated hoist which have a particularly precise control characteristic adapted to the respective user and the respective usage situation and are thus perceived as particularly pleasant in use, it is provided that an input choke is arranged in at least one control fluid inlet in order to adjust the flow rate or the volume flow to the control valve and/or the control characteristic of the handheld controller.

Abstract: A fluid-operated hoist and method for operating a fluid-operated hoist. The hoist is particularly convenient to produce and install and can be permanently and reliably operated without frequent maintenance. The hoist includes a fluid supply line supplying an operating fluid to the hoist for operating the hoist, a generator connected to the fluid supply line for generating electricity by the operating fluid, and an electrical consumer on the hoist that is operated by the electricity generated by the generator.

Abstract: A control valve assembly for indirect pneumatic control and method for controlling a working fluid pressure, which enable precise, sensitive and speed-variable controlling. The assembly includes two valve units, a working fluid inlet, and a control fluid inlet. A working fluid channel connects the working fluid inlet through the two valve units to an outlet. A valve piston arranged within a valve cylinder of the valve units is movable between open and closed positions. A spring element biases the valve piston toward the closed position, and a control pressure chamber applies a control pressure counteracting the spring element's bias. When a control pressure is applied in the first chamber, the first valve piston is moved to the open position.
