摘要

The vibrator consists of a motor which drives two symmetrical sets of vibrating wheels, the trailer or tanker having a special suspension consisting of rubber studs, pneumatic cushions, spiral springs or another suitable suspension method. The vibrator consists of two identical wheels which are each provided with an out-of-balance mass disposed symmetrically. The vibrator is mounted at a variable angle underneath the trailer or tanker, one end being hinged, the other end being connected to an hydraulic jack, screw or another type of adjuster. The speed of unloading is altered by varying the frequency of vibration.
