A ram assembly comprises a top plate defining one or more clamp openings and one or more top plate lift openings, a bottom plate defining one or more anchor openings, a lift plate defining one or more lift plate ram cable openings, and one or more ram wire rope assemblies. Each ram wire rope assembly extends through one lift plate ram cable opening and between one clamp opening and one anchor opening to inhibit movement of the top plate, the bottom plate, and the lift plate relative to each other. The top plate lift opening is sized and dimensioned to allow at least a portion of the actuator rod assembly to extend through the top plate. The lift plate is adapted to be secured relative to the actuator rod assembly.

Segmented ram systems and methods for hydraulic impact hammers

A hydraulic impact hammer for striking a pile has a main housing, a ram supported, a coupler rod, a conversion housing, a hydraulic actuator, and a ram connector. The hydraulic actuator defines an actuator rod, a lifting head, and a lift connector. The lifting head defines an upper wall and a lower wall. The lift connector attaches the actuator rod to the upper wall of the lifting head. The ram connector attaches the coupler rod to the lower wall of the lifting head. Operation of the hydraulic actuator raises and lowers the ram to strike the pile.

Hydraulic impact hammer systems and methods

A guide system for allowing a diesel hammer to be supported by a plurality of support systems comprises a primary channel system and a pair of first and second channel adapter assemblies. The primary channel system rigidly connected to the diesel hammer to define a pair of primary channels and a primary spacing distance. Each first channel adapter assembly defines a first secondary channel. The guide system operates in a first configuration and a second configuration. In the second configuration, each of the first channel adapter assemblies is detachably attached to the primary channel system such that the first channel adapter assemblies define a first secondary spacing distance between the first secondary channels, the first secondary spacing distance is different from the primary spacing distance, and portions of a second support system of the plurality of support systems are received within the first secondary channels.

Guide systems and methods for diesel hammers

An adapter assembly for transmitting a drive force from a pile driving system defining a drive axis to a pile defining a pile axis comprising a base assembly and an adapter assembly. The base assembly is operatively supported such that the drive force is transmitted to the base assembly. The adapter assembly comprises a plate member, a skirt member defining a skirt chamber, and an adapter connector configured to support the skirt member relative to the base assembly, the plate member, and the pile member. The adapter assembly substantially aligns the drive axis with the pile axis. The drive force is transmitted from the base assembly to the plate member. The pile is received within the skirt chamber such that the drive force is transmitted from the plate member to the pile. The skirt member is substantially isolated from the drive force.
