    Patent number: 4062136
    Abstract: A scraper vehicle includes a body having a longitudinally shiftable apron therein for pushing a load of material from the scraper body. The apron is shifted in a fore-and-aft direction by a pair of hydraulic rams. A retractable and extensible power assist mechanism is connected to the apron and is in a retracted energy storing condition when the apron is in a rearward position. The release of stored energy in the power assist mechanism assists in shifting the apron in a forward or unloading direction.
