TRAVELLING THICK MATTER PUMP

摘要

The invention relates to a travelling thick matter pump with a driving mechanism presenting an automobile engine(40) and a gear box (42), wherein the driven shaft (46) of the gear box can be connected via an interposable transfer gear (48) to a hydraulic pump (54) in order to drive the thick matter pump (24) and a speed limitation device for the setting of a maximum engine speed during operation of the pump. In order to selectively ensure optimum pump operation, according to the invention the transfer gear (48) presents at least two step-up ratios after whose activation differing maximum engine speeds can be set via the speed limitation device (70).
