International Classification:

B62D033/02

US Classification:

2961832, 2961831

Abstract:

A reinforced payload container may include a panel forming at least one of a floor, a sidewall, and a front wall. A first plurality of ribs may be attached to the panel and may include a first free edge and a first panel edge. A second plurality of ribs may also be attached to the panel and may intersect with the first plurality of ribs. The second plurality of ribs may include a second free edge and a second panel edge. The first plurality of ribs may include first rib slots along the first free edge, and the second plurality of ribs may include second rib slots along the second panel edge. The first rib slots and the second rib slots may be aligned so that the first rib slots receive the second ribs and the second rib slots receive the first ribs.

Clifford E. Miller - Clinton IL

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

B62D 5514

US Classification:

305145

Abstract:

An undercarriage assembly of a work machine includes a first drive track chain and a second drive track chain. The undercarriage assembly also includes a first hydraulic actuator mechanically coupled to the first drive track chain so as to adjust tension on the first drive track chain and a second hydraulic actuator mechanically coupled to the second drive track chain so as to adjust tension on the second drive track chain. The undercarriage assembly further includes a slack adjuster assembly. The slack adjuster assembly has (i) an adjuster housing defining (a) a main chamber, (b) a fluid inlet, (c) a first fluid outlet which is fluidly coupled to the first hydraulic actuator, and (d) a second fluid outlet which is fluidly coupled to the second hydraulic actuator, (ii) a first piston positioned in the main chamber, the first piston selectively couples the fluid inlet to the first fluid outlet, and (iii) a second piston positioned in the main chamber, the second piston selectively couples the fluid inlet to the second fluid outlet. Movement of the first piston from a first decreased-tension position to a first increased-tension position causes actuation of the first actuator so as to increase tension on the first drive track chain. Movement of the second piston from a second decreased-tension position to a second increased-tension position causes actuation of the second actuator so as to increase tension on the second drive track chain.

International Classification:

F16D 6538

US Classification:

188196A

Abstract:

A hydraulic brake slack adjuster disposed between a brake valve and an actuator of a brake mechanism has a first piston exposed to pressurized brake fluid from the valve and a second larger piston connected to the first piston for outputting brake fluid to the brake actuator with the fluid output to the actuator being greater than the volume of input fluid from the valve. This permits a smaller pump to be used while maintaining sufficient brake operation speed.
