    Abstract: A crane has a generally vertical, pivoting crane shaft (17) which supports a crane boom (23, 24) which can be raised and lowered by means of a hydraulic cylinder (28). The crane shaft (17) is supported at its lower end by a pivoting arm (20) which is actuated by a power unit (31), the crane shaft (17) being capable of being turned about its own longitudinal axis. Changes in the angle of the boom are reduced by the axis of the crane shaft (17) being tilted at a narrow angle by the supporting arm (20). The rotating movement of the crane shaft (17) is controlled by a link arm (37) which is firmly attached at one end and joined to an arm (36) which protrudes from the side of the crane shaft (17).

    Abstract: Piston engine, with a cylinder housing (11) with at least two cylinders (12, 13) each containing a piston (17, 18) with a piston rod (19, 20) which is linked to a rocker member (23). The rocker member is integrated with a crank mechanism (26) carried by a shaft (14) being journalled in the cylinder housing. The shaft is operating a valve (15) integrated in the cylinder housing (11). The rocker member (23) is annular and linked to the crank mechanism (26) over a connecting element (31). This piston engine can be provided as a steam motor and as a combustion motor or Stirling motor. It can also provide a pump or compressor.
