摘要： In a working vehicle including a crane (21) for handling loads and a driver's cab (11), both crane and cab are rotatably mounted on the vehicle, each about its vertical axis, and controlled such that a turning angle beta of the crane results in a turning angle alpha of the cab, alpha being an optional function of beta, e.g. half of beta. The driver can thus carry out all the working operations desired for the crane without having to turn his head uncomfortably.

摘要： A method of controlling an internal combustion engine (14) having a power control 15) and a variable hydrostatic transmission (16, 17) including a hydraulic pump (16) driven by the internal combustion engine, and a hydraulic engine (17) connected therewith. By automatic adjustment of the power control (15) and the ratio (E) of the hydrostatic transmission (16, 17) independently of each other according to a predetermined mathematical control function (Fig. 1) which describes a desired relationship between power and rotational speed of the internal combustion engine, a specific discrete power output is delivered between zero load and full load only at an associated discrete rotational speed of the internal combustion engine.
