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.

A method for controllably moving a machinery platform of a work machine having an electro-hydraulic system is disclosed. The work machine includes at least one swing motor configured to move the machinery platform . The changing speed of the swing motor is determined. A solenoid actuated valve is controlled in response to the determination. The solenoid actuated valve is configured to responsively produce a relief valve pilot signal . The two-way relief valve is controllably shifted in response to the inputted relief valve pilot signal . At least one of a high pressure by-pass valve and a low pressure by-pass valve is selected in response to the two-way relief valve shifting.

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.

The frames of many construction machines comprise a complex compilation of fabricated sections or massive cast members that are not necessarily intended to handle a specific type of loading applied to the frame assembly. The present invention provides a frame construction that includes a pair of laterally spaced plate members. Each plate member has a first end portion constructed of a substantially solid plate. A second end portion of the plate members define at least one opening that provides an integral portion of a beam assembly. The first end portion is positioned in the frame construction to accommodate a first type of loading, while the second end portion is located in an area to accommodate a second type of loading.

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.

A Rapid Fire Trigger Activator and accessory gun stock used to convert any semi-automatic carbine, rifle, or shot gun to nearly the firing capability of an automatic weapon which includes, a main side plate, having a pivot pin; a slide tube; a fore end hand grip; a slotted cam plate; a transfer bar; a swing out safety block; a trigger activator having a spring load plunger pin; and a nylon bearing block. When the fore end hand grip is pumped back and forth it will cause the transfer bar to pivot about the pivot pin which in turn will cause the trigger activator to be displaced towards the weapons trigger by the swing out safety block due to the up and down displacement of a transfer bar slot pin as it follows the cam slot. The trigger of the weapon is always fully accessible and functional whether or not the safety block is in place or not. The swing of the safety block is fitted with a spring loaded plunger pin that allows for its adjustment to various types of weapon trigger configurations and different types of weapon sear actions. On the forward portion of the main side plate is a nylon bearing block which has a frictional slide lock which functions as an additional safety feature to prevent the unintentional movement of the slotted cam plate due to the accidental displacement of the fore end hand grip.
