SELF-LOADING CONTAINER CARRIER TRUCK

Abrégé anglais

ABSTRACT OF THE DISCLOSURE
A self-loading container carrier truck is disclosed.
This truck includes an elongated truck chassis, slide rails fixed
to the chassis and longitudinally extending lengthwise thereon,
a frame slidably engaging the slide rails and slidable fore and
aft longitudinally of the truck, an L-shaped arm mounted on the
slidable frame and pivoting relative to the latter, hydraulic actuators
connected between the frame and the chassis to slide the frame between
a foremost and a rearmost position, and a double-acting, telescopic
hydraulic cylinder and piston unit pivoted to the frame and to the
elbow portion of the L-shaped arm for pivoting the latter.

Revendications

The embodiments of the invention in which an exclusive property
or privilege is claimed, are defined as follows:
1. A self-loading container carrier truck comprising a truck
chassis, a guideway mounted on said truck chassis and extending longi-
tudinally thereof, a movable frame operatively engaging said guideway

Description

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

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.
