A horizontal take-up carriage (Fig. 14) is subject to
misalignment due to loose track gauge, fouled rails, or even
jumping off the track.
V-shaped rails will hold the gauge tight
and, with the apex upward, are self-cleaning. Hold-down rails
or hooks extending under the flange of the track structure will
prevent jumping off the track.
With the empty belt trained satisfactorily, good operation with
load is usually ensured. Disturbances that appear with load are
usually due to off-center loading or to accumulation of material
from the load on snub pulleys and return idlers.
When equipment is known to be properly aligned, training
action should be taken slowly – that is, in small steps, because
the belt requires some time to respond to corrective measures.
It should begin at some point preceding the location where
runoff occurs, and gradually proceed forward in the direction of
belt travel, until the runoff condition has been corrected. Under
some conditions of operation where the conveyor is not level,
is extremely short or is too wide to be affected by permissible
crowning, belts with a special guide strip have been used. This
V-guide strip runs loosely in grooved pulley and idler rolls.
Guide strips are not recommended nor are they necessary for
the long conveyors normally encountered in industrial use.
