Rollers Speed Up Loading and
Unloading Of Lumber-Four-
wheeled Trailers Aid With
Logs and Machinery.

When buying trucks for commercial
and industrial use tine shape and
weight of the commodity to be hauled
should determine the style Of body
as we'll as the springs or the type of
motor. Nowadays manufacturers build
an almost endless variety of special
bodies to suit special purposes. Inter-
esting examples of bodies and varia-
lions used in numbering and other
trades show how necessity is mother
ing invention every day in the truck
world.
Usually lumber comes in length
greater than the usual motor truck
BODY. Often the individual pieces
weigh considerable and it takes a
quantity of different pieces to make a
capacity load for an ordinary heavy
motor truck. Where the standard body
is used each board or plank must be
lifted to the height of the load plat
form from AZ to As inches and
pushed into place. When loaded II
will be found that a considerable por-
ton of the average load extends back
beyond the trail board of the body,
unbalancing the load and overlooking
the rear axle, springs and tires.
ENTER THE ROLLER BED
! Arrived at destination it must be
painstakingly unloaded piece by piece
SO slow and expensive is this method
| of handling lumber-which was uni
versal when the horses sway was held
without dispute--that very few pro-
handle lumber by truck without spe-
cial appliances.
The most common and generally sat
isfactory appliance for handling lum-
/ Der on a motor truck chassis is the
roller bed. This comprises a series OF
rollers laid transversely across the
chassis sills, as wide as the load plat
form. They are placed from two IL
three feet apart and run in large bush
ings which are kept well creased. The
rear-most roller is usually provided
with ratchet and pawl so that it may
be restrained from turning backward
the other rollers being free. Stakes a
the side are provided to hold the lum
her laterally Usually also this role
bed is set at considerable incline
| higher at the front than at the rear
In some cases this angle is grea
enough to permit the longer boards t
extend forward over the drivers seat
thus properly distributing the load. II
other cases the drivers seat is singh
width, with an extension Of the Loaf
pla tform at his side SO that half of tn
load can overhang at the front.
TRAILER FOR LOGGING
Such bodies are sometimes loaded
piece by piece by an adequate loadin,
force at the lumberyard and in othe
cases the lumber is slid from han'
wagon the same height as the true.
platform. When in place the rear role
is locked by means of the pawl an,
the lumber roped in place. Arrive,
at destination the ropes are cast of
and the pawl released, whereupon tn
angle of the bed causes the lumber Il
slide backward and off the truck.
Long logs, spies or telegraph pole
are usually carried on trucks and trail
ers. These trailers are known as dol
lies and are sometimes two wheeled
and sometimes four wheeled, beini
provided with flat pivoted bolste
over it's wheels, carrying heavy stake
on either side. The dolly has shor
tongue to which a chain is usual
fastened and connected with the rea
end of the truck. Where four wheel
are used these are placed very clos
together, with no provision for turning
such dollies being used only for Yer
heavy loads and to decrease the stres
on the wheel boxes.
Sometimes trucks used for this pur
pose are fitted with collapsible der
ricks by which the long poles may b
lifted to vertical position and b
maneuvering the truck actually set i
, their holes.
Heavy machinery is usually handle
on four-wheeled trailers, provide
with undressing frames to bring tn
load platform as near to the ground a
, possible. In some cases the truck plat
form itself Is brought very low by fit
ting goose neck frame, slung beneat
. the rear axle, or by fitting very sma
wheels to the truck.
Large steel beams or sections 90

ried on trailers having very larS
, wheels and an arched rear axle, S
that the beam or pipe may be tied t
