APPARATUS FOR LOOSENING FROZEN COAL IN HOPPER CARS

Frozen lumps of coal in conventional hopper cars are loosened by lowering an assembly of vertically oriented probe elements into the car while simultaneously vibrating the assembly. The vibratory structure is mounted on a gantry arrangement which also supports a supplemental probe arrangement utilizing impact forces to loosen coal in hopper cars having interiors different from those of the cars operated on by the vibratory arrangement.
