This inv~ntion relates to a container carri~r truok of the
typ~ provid~d witt, a mechanism to load a contain~r thereon and to
unload the ~ame~
A mechani~n! of th~ abovs type is described in Canadian Patent ~ -
No. 956,911 dated Octob~r Z9~ 1974 and ~ntitled. I'D~lCE FUR LOADIN~ A
SKIP ON TO A VEHICLE". ThiR m~chanism includes an L-~haped arm slidabla
in slides pivot~d to the vehicl~ chas~ieO Hydraulic jasks s~rve to
piuot the assembly of slid~s and arm for loading and unlDading a con-
tain~r~ Th~s~ jackx aot on the elid~s9 which in turn rotate the L-~haped
1~ arm. This arrangem~nt r~4uires h.igh pressur0 jack~ and uery sturdy
construction of ths arm and elides, resulting in a mschani~m o~ sxcessiue
w~ight with a resultant decrea~e uf the truck payload~
It is an obj~ct o~ the preeent invention to prouide a
mschanism oP ths charactsr d0scribed, which is o~ min.~mum wsight for a
given payloadO
It is a further obJect of the present inuentlon to prouide
a self-loading oontainer carrisr truck wh~rein the squipm~nt or mechaniam
for the s~ loading and unloading alao prod`uces~irm holding cf the
- container in ~ranaport p~sition thereon. ;~;

An L~shape arm i9 mounted on the abo~e-rnentioned movable
frame and pivoted relative ther~to. The L-shape ar~ has a rigid ~tructuro
including a base section 9 and a post section 10. The base section 9
comprises a pair oP eide memb~rs 11 rigîdly interconn~ctsd by cro
m~mbsrs 12 and by nross me~ber 130 The post seation 10 comprises ~
1~ pair oP opposite 9ide walls 14; a rear wall 15~ and a top 16 cooperatively
forming a forwardly open ancloeura. A hook 17 i3 weldsd on the top 16~
The ~ore and a~t sliding D~ the movable frame 6-7_~ and o~ the
arm 9-10 therewith is produced by a pair o~ hydraulic cylinders 1
longitudinally extending l~ngthwise of the truck chassis.
The cylind~rs 1
are connscted at the rear to a pin 19 extending transversely of the
truck chas~is. The forward end of the cylinders 1~ ara fixedly connected
~ to a crossbar 20 piuotally extending tran~v~rsely ~hrough brackets 21
; projecting from the fres end of the side members 11. A pair of poats 22
upwardly stand in linB with the di~placement of the movable frame.
, . . .
The posts 22 arB rigidly ~ountsd on a transverse plate 23
in turn rigidly seour~d to tha truck chaesis. The post~ 22 are eQch
provided with a forwardly opening notch to cooperati~ely form a plvotal
ab~tment ~ar the cro~ar 20 upon rear~a rd displacement of the latter
to the position o~ Figure~ 2 and 3.

thereaftar extended to rearw~rdly pi~ot th~ arm 9~}0 abaut the trane~
verse pivot axis ~efin~d by th~ notch in the post~ 22, ~e ~hown in
Figure 3. The hook 17 is then unhooked Pro~ the ro~pin 2~ at the
front ~nd top o~ the container C.
To load 9 container~ the hook 17 ie eng~ged under a oros~pln ~;

cylinder 23 to retr~t th~ same~ The front of the cont~iner C is thu3
ll~ted up and th~e~fter pulled ~or~ard o~er the truck body. The
hydr~ulic cylinders 1~ ~re oynohronouoly aGtuated to fully pull the
