Abstract: Failure difficulties due to high stress conditions in truck loading mechanisms are avoided in a construction including a tilt link (44) pivoted to a secondary link (46) which extends under and up the front of the dumpster (20) located on a truck. A dump link (50) is located under the dumpster (20) and is pivoted to the truck frame (14). A first extendable motor (82) is provided for tilting the secondary link (46) relative to the truck frame (14) and a second extendable motor (74) is provided for pivoting the tilt link (44) relative to the secondary link (46). The tilt link (44) has a tab (106) underlying a tab (94) on the dump link (50) so that when the tabs (94, 106) are engaged, the entire linkage (16) may be operated in a dump mode and when the tabs (94, 106) are disengaged, the secondary link (46) and the tilt link (44) may be moved in an on or off loading mode.
