Abstract: A floor transport system with a rail guided floor transport vehicle and a guide rail system is recessed in the floor or ground plane and has a slotted track channel for guiding the vehicle along a travel path and at least two current conductors. At least two running wheels and at least one drive wheel as well as guide elements sliding in the track channel and current collector shoes are secured to the frame of the vehicle and operatively connected to at least one drive unit which is secured to the vehicle frame and includes the drive wheel. The front guide elements and preferably also the current collector shoes are combined in particular subassemblies which can rotate about respective vertical axes, wherein at least one of the subassemblies is mechanically and electrically linked to a respective drive unit for steering the vehicle.

Abstract: An agricultural machine has a feed passage for stalk products, a cutting device provided on the feed passage and having a plurality of turnably supported knives which are arranged in a row and extend in their cutting position into the feed passage, spring loaded knife levers which hold the knives in the cutting position, so that under the action of a foreign body the knives can turn out against a spring loading from the feed passage, a joint traverse with which the knife levers are displaceably connected through hingedly connected rods, a frame which is downwardly turnable to a fixed abutment and in which the cutting device is arranged, the frame having side walls provided with slot guides, the traverse being displaceably received at both ends of the traverse in the slot guides of the side walls of the frame, and a cylinder-piston a unit which engages with the traverse.

Abstract: The invention relates to an apparatus for power collection and for control f motors on a chassis of overhead trolleys. The apparatus includes a casing for receiving the control device, which is detachably mounted on the rear side of the overhead trolley chassis by means of a groove-snap lock. The casing is provided on its front side with a receiving device for receiving carbon brushes which engage the power tracks and serve to supply the power.
