Abstract: A hood assembly for a mobile excavator has a lever arrangement by means of which the hood which--with respect to the driving direction--is arranged behind the driver's cab, can be swivelled up. The hood has a first projecting end wall which is directed toward the driver's cab and which has a set-off area with respect to a second set-back end wall. Both end walls have a course along oblique planes which extend at an acute angle with respect to the body and which are arranged approximately in parallel to one another. Outer side levers and a center lever, which is arranged in-between, of the lever arrangement form a four-bar mechanism with the hood by way of which the lower boundary edges of the end walls during the swivelling in the overlapping area with the driver's cab and a tank can be moved within a gap as well as along a front wall of the tank on a straight course along the planes.

Abstract: A swivellable fastening system for a headlight unit on an excavator comprises a jib which is pivotally connected in a jib swivel block and which, by way of a working cylinder connected with a crank mechanism, can be swivelled into several working positions as well as into a transport position deposited on the excavator body. By way of a holding arrangement, which is supported in bearings of a connecting control arm of the crank mechanism, the headlight unit is swivellably fastened in such a manner that, in the transport position of the jib, the unit is arranged approximately in a vertical transverse plane of the vehicle with a fixedly arranged other headlight unit and has a cone of light aligned in the driving direction which has an angle .alpha.. The headlight unit can be swivelled into the working position by the connecting control arm.
