Rubbish collection vehicle with an improved container lifter

A rubbish collection vehicle, comprising:

• a frame;
• a propulsion system;
• a caisson received by the frame and to store contents of containers;
• and
• a container lifter mounted to the frame, the container lifter having:
• at least one main arm pivotably mounted about a first pivot axis so as to take a bottom position and a top position relative to a low-high direction;
• a reinforcement member pivotably mounted to the at least one main arm about a second pivot axis;
• a seat mounted to the reinforcement member and which is to receive a container so as to raise same;
• and
• at least one auxiliary arm pivotably mounted about a third pivot axis, and also pivotably on the reinforcement member about a fourth pivot axis;
• wherein:
• a spatial distance between the second pivot axis and the fourth pivot axis is greater than a spatial distance between the first pivot axis and the third pivot axis;
• the seat is pivotably mounted to the reinforcement member about a fifth pivot axis so as to selectively take a position against the reinforcement member between the bottom position and the top position of the at least one main arm, and an unloading position when the at least one main arm is in the top position;
• and
• the seat is pivoted about the fifth pivot axis in such a way that the container received on the seat is also pivoted about the fifth pivot axis in order to be emptied of its contents.

A method for emptying a container, the method comprising:

• providing a container lifter having:
• at least one main arm pivotably mounted about a first pivot axis so as to take a bottom position and a top position relative to a low-high direction;
• a reinforcement member pivotably mounted to the at least one main arm about a second pivot axis;
• a seat mounted to the reinforcement member and which is to receive a container so as to raise same;
• and
• at least one auxiliary arm pivotably mounted about a third pivot axis, and also pivotably on the reinforcement member about a fourth pivot axis;
• wherein:
• a spatial distance between the second pivot axis and the fourth pivot axis is greater than a spatial distance between the first pivot axis and the third pivot axis;
• the seat is pivotably mounted to the reinforcement member about a fifth pivot axis so as to selectively take a position against the reinforcement member between the bottom position and the top position of the at least one main arm, and an unloading position when the at least one main arm is in the top position;
• and
• the seat is pivoted about the fifth pivot axis in such a way that the container received on the seat is also pivoted about the fifth pivot axis in order to be emptied of its contents,
• raising, in a first phase, the at least one main arm to attach the container to a comb of the seat, then raising the at least main arm further in order to raise the container to the starting of the closing of the clamp, and then closing the clamp on an upper edge of the container;
• and
• initiating, in a second phase, rotation of the container, then completing the rotation of the container using a cylinder.
