umn lift device, with top and bottom anchors, is able
to load side-by-side process vessels from paper bags,
drums, intermediate bulk containers, boxes, bulk bags,
silos, storage containers, and feed bins.
A mobile vacuum conveying system, as shown in
Figure 3, operates in the same fashion as a vacuum
conveyor mounted on a column lift device but is mov-
able with one operator and is able to service multiple
process vessels at varying discharge heights. When not
in use, operators can roll the mobile vacuum conveying
system from the work area to save on floor space.
These two conveyor types are compatible with
OSHA's Walking-Working Surfaces standard to protect
against falls and slips and back injuries from repeti-
tively carrying bags and boxes upstairs to load or clean
equipment. The ability of operators to bring equipment
down to floor level for cleaning reduces downtime,
labor costs, and potential injury costs. And when
constructed within the FDA's Food Safety Moderniza-
tion Act sanitation regulations, the vacuum conveyor
mounted on a column lift device and mobile vacuum
conveying system are ideal for food, nutraceutical, and
pharmaceutical applications. PBE

A mobile vacuum conveying system can service mixers
and other process equipment by allowing for varied
discharge heights, discharge rates, mobility between
process equipment, and easy floor-level cleaning.
