proper.
Large amount Of labor required to
get package freight to and away from
lconveyor when same is worked to ca
pacity.
|, High cost Of operation of complete
system, due to rehandling OF freight
piece by piece, at the ends of the con-
veyor. Also, increased cost of in
stallation and loss of time OF men
and trucks when same are carried on
tconveyor.
Necessity Of providing for adjust
ment Of lower end of conveyor to take
care of changes in stage Of river.
This complicates the mechanical fea-
lures and makes the cost of the sys-
tenn much higher than that of systems
with fixed ends, such as are extern
sively used on shore.
Cannot handle all freight coming
to the terminal, but only package
freight up to predetermined size or
weight.
Conclusions: From the above, we
may conclude that continuous con-
veyors are best adapted to the hand
ling Of bulk commodities where same
are automatically fed onto the con-
veyor from hopper and discharged
by the conveyor into a bin or through
"a chute into the hold of a vessel.
Continuous conveyors are also we'll
adapted to handling packages of uni
form size and weight where the ends
Of the conveyor do not have to pc
adjusted to meet varying stages Of
water. Such adjustment adds greatly
to the cost of the installation in
CONFERENCE.-The, hosting and equaliz-
ing machinery, supporting trusses,
etc.
THE use OF continuous convey
ors is only recommended for hand
ling bulk cargoes, as mentioned
above. or for handling large numbers
OF packages of practically uniform
size and weight, such as barrels OF
apples. or sugar, flour, sacks of cof-
fee, etc, where the ends of the con-
veyor are fixed in position. Their
use at universal freight handlers be-
tween vessel and dock is not recon-
mended because of the expense of
rehandling at the ends of the con-
veyor, nor where the variation in
water level is large, owing to the ex-
Ipense of the adjustment necessary to
meet such variation in water level.
In special cases the use of the con-
veyor may be warranted to assist the
hand truck by lifting it UP short,
steep grades
