Abstract
Abstract A vehicle for loading, unloading and tipping a container comprises a first frame pivoted at the rear of the vehicle on a bedframe, and extending (normally) forwardly from the pivot underneath the container when loaded, a second frame or second members pivoted to the first frame and extending forwardly thereof under the container, an L-shaped third member having the outer end of its horizontal limb pivoted to the second frame members underneath the container and its upright limb provided with at least one hook to attach to the container, with the upright limb in front of the container, two tie-rods-cum-struts pivoted at their front ends to the upright limb and at their rear ends to the rear end of a hydraulic ram, the front end of the ram being connected to the bedframe, the ram also being connected with the second frame or members, so that the one ram can both pivot the third member relative to the second frame or members and also pivot the second frame or members and the third member as one unit relative to the first frame or (when the second frame or members and the first frame are in fixed relationship due to engagement with the container) pivot the first frame, second frame or members, third member and container as one unit relative to the bedframe for tipping.

Total Claims: 19
Claim 1
Independent Claim
329 words
A vehicle for transporting a container, the vehicle comprising a motorised mechanism for moving the container onto the vehicle over any one side of the vehicle, tipping the container and moving the container off the vehicle over said side of the vehicle, the mechanism comprising at least one first member pivotally mounted close to the said side of the vehicle; comprising at least one second member pivotally connected to the at least one first member, comprising at least one third member pivotally connected to the at least one second member, each third member being attachable to the container for the movement of the container onto and off the vehicle by pivotal movement of the at least one second member together with the at least one third member relative to the at least one first member, comprising at least one fourth member and at least one fifth member and comprising motor means, the at least one fourth member being pivotally connected to the at least one third member, the at least one fourth member also being connected to the at least one fifth member, the at least one fifth member in turn being movably attached for relative movement with the at least one second member such that movement of the at least one fifth member relative to the at least one second member produced by the motor means causes linear translation of the at least one fourth member relative to the at least one second member, in turnng causing inter-related pivotal motion of the at least one third member relative to the at least one second member so as to move the container relative to each second member and causing interlocking engagement between corresponding portions of each second member and the container, such that the container and the first, second and third members together with the fourth and fifth members can be tipped by the motor means by pivotal movement as one about the pivotal mounting of each first member.
