Abstract
A material handling machine includes a linkage assembly connected to a machine frame of the material handling machine. The linkage assembly configured to transport material from a front side of the machine frame to a rear side of the machine frame. The linkage assembly includes a first and a second guide rails associated with the machine frame. The linkage assembly further includes a first boom and a second boom having one end pivotally connected to the first guide rail and the second guide rails. A first and a second lift mechanism are pivotally connected to the first boom and second boom, respectively.
Claims9
A material handling machine comprising:
- a set of ground engaging members;
- a machine frame connected to the set of ground engaging members, the machine frame including a first side-wall and a second side-wall opposite to the first side-wall;
- a linkage assembly connected to the machine frame, the linkage assembly configured to transport material from a front side of the machine frame to a rear side of the machine frame, the linkage assembly including, a first guide rail associated with the first side-wall, a second guide rail associated with the second side-wall, a first boom having a first end pivotally connected to a first slider, the first slider configured to move along the first guide rail, and a second end of the first boom pivotally connected to a loader bucket, a first lift mechanism pivotally connected to the first boom a second boom having a first end pivotally connected to a second slider, the second slider configured to move along the second guide rail, and a second end of the second boom pivotally connected to the loader bucket, and a second lift mechanism pivotally connected to the second boom;
- a first slider pivotally connected to the first end of the first boom and configured to move along the first guide rail;
- a third guide rail provided on the first side-wall and a third slider configured to move along the third guide rail, wherein the first lift mechanism is pivotally connected to the third slider;
- a first intermediate link connecting the first slider and the third slider;
- and
- a first slide actuator disposed on the first side-wall, the first slide actuator directly connected to the first intermediate link.
A linkage assembly for a material handling machine having a set of ground engaging members and a machine frame connected to the set of ground engaging members, the linkage assembly comprising:
- a first guide rail associated with a first side-wall of the machine frame;
- a second guide rail associated with a second side-wall of the machine frame;
- a first boom having a first end pivotally connected to a first slider, the first slider configured to move along the first guide rail, and a second end of the first boom pivotally connected to a loader bucket;
- a first lift mechanism pivotally connected to the first boom;
- a second boom having a first end pivotally connected to a second slider, the second slider configured to move along the second guide rail, and a second end of the second boom pivotally connected to the loader bucket;
- a second lift mechanism pivotally connected to the second boom, wherein the linkage assembly is configured to cause the loader bucket to move from a front side of the machine frame to a rear side of the machine frame, while the loader bucket is elevated above the machine frame;
- a third guide rail provided on the first side-wall and a third slider configured to move along the third guide rail, wherein the first lift mechanism is pivotally connected to the third slider;
- a first intermediate link connecting the first slider and the third slider;
- and
- a first slide actuator disposed on the first side-wall, the first slide actuator directly connected to the first intermediate link.
