VMRR & VMBB Metallic 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.
