Impact or Air-Cushioned Vibrator for Railroad Cars
Installation and Operating
Kits
VMRR
and VMBB air-powered vibrators eliminate the hazards connected
with climbing around railroad cars and poking their contents
to keep the materials flowing freely. In addition, their use
can reduce unloading time by as much as 30%. (These vibrators
can be handled by one man). The VMRR for railroad cars is
designed for use with covered hopper cars that are equipped
with female brackets. The VMBB for railroad cars is used on
all other types of covered hopper railroad cars, as well as
portable installations on large bins. These units utilize
either the VMS (impact) or VMSAC (air-cushion) vibrator with
either the male wedge (VMRR) or bolt-bite (VMBB) mounting
head. Specify VMRR-AC or VMBB-AC when quiet operating,
air-cushioned vibrators are required.
