Appl. No.:

13/677846

Inventors:

Caterpillar Inc. - Peoria IL, US
Jeffrey K. Berry - Yorkville IL, US
John R. Picolet - Manhattan KS, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

E02F 3/40

US Classification:

37444, 414715, 2940701

Abstract:

A machine bucket assembly includes a bucket having a top section, a bottom section, and a curved middle section. The bucket assembly may also include a kinematic reaction point about which the bucket is configured to rotate. A loadability index of the bucket may be between approximately 0.95 and 1.05. The loadability index is a ratio of a distance between the kinematic reaction point and a tip of the bottom section and a distance between the kinematic reaction point and a tip of the top section.

US Classification:

37444

Abstract:

A machine bucket may include an upper pin hole and a lower pin hole. The machine bucket may also include a bottom section. A distance between the lower pin hole and a tip of the bottom section may have a first length. The machine bucket may also include a top section. A distance between the lower pin hole and a tip of the top section may have a second length. A ratio of the first length to the second length may be equal to a value between approximately 0. 95 and 1. 05. The machine bucket may further include a middle section located between the bottom section and the top section. At least a portion of the middle section may be curved.
