Abstract: A damper system for a power cell includes a single-piece top damper element disposed on the power cell, a pair of middle damper elements disposed about a mid-portion of the power cell, and a single-piece bottom damper element that is formed from a material having Shore hardness in the range of about 90 A to 95 A. The middle damper elements are mutually identical in construction, and include interlocking features that are configured to allow a releasable engagement therebetween. The bottom damper element defines a central opening therein, and includes a base plate disposed about the central opening. The bottom damper element further includes appendages extending axially from a top side of the base plate, and a lateral projection extending radially inward from each of the appendages. The lateral projection is configured to abut a top side of a keel member defined at a bottom portion of the power cell.

Abstract: Impact rippers are useful for transmitting high impact blows to a hard material for fracturing the material. When a linear reciprocating ram is used a mounting arrangement which maintains the ram in a neutral position, when no force is applied to the tip, must be used to divert impact force into a pivoting shank assembly. The subject impact ripper apparatus includes a shank assembly with an impact surface and a cavity for mounting a linear ram having an impact surface. Means positions the linear ram within the cavity so that the impact surface does not extend outwardly beyond a rear impact surface of the shank assembly when no force (F) is applied to the tip. This arrangement provides for diverting impact force into the shank assembly when no force is applied to the tip.

Abstract: Impact rippers are useful, for example, in fracturing rock and other hard material which is to be excavated. Known systems using structures which mount the impact hammer and the linear ram within a single housing transmit vibrations into the mounting frame and are difficult to service and expensive to maintain. The subject linear impact ripper apparatus has an impact hammer having one end resiliently mounted to a mounting frame and another end slidably mounted on one of the linear ram and the tool holder. Thus, the disclosed linear impact ripper apparatus reduces vibrations transmitted to the mounting frame and has separate elements for ease of service and reduced maintenance cost and maintains the alignment between the separate parts of the structure. The arrangement allows the connection between the impact hammer and one of the linear ram and the tool holder to be sealed from atmosphere.
