The upper part and lower part is pivotally attached to each other at the middle or back part, and via a pivotal and slidable connection (11, 12) in the front part.

The rotor assemblies drive a planetary member (50) for rotation about its axis through a sliding pin connection (56).

At least the first rotator (12) is mounted rotatably and slideably for rotation and axially movement relative to the second rotator (13) in response to water pressure when the shaft is moved forwardly in a body of water.

The upper part and lower part is pivotally attached to each other at the middle or back part, and via a pivotal and slidable connection (11, 12) in the front part.

The rotor assemblies drive a planetary member (50) for rotation about its axis through a sliding pin connection (56).

A first pivotal connection pivotally secures the pivotal link relative to the chassis and defines a first pivot axis and a second pivotal connection couples the pivotal link to a trailing arm and defines a second pivot axis.

According to the invention, the slipform sides have no connecting yoke.

The reciprocating tool attachment includes an oscillating link having a pivot at an end of the link and a blade coupled to the pivot.

The access door assembly may be pivotally coupled to the support surface and may include a major door pivotally coupled to a minor door.

A pivot link is pivotally mounted to the bracket.

Pivot connectors are provided that are received in pivot recesses formed in the latches.

The actuating end (212) of the linking member has a sliding-contact surface with which the latch member (260) makes sliding contact.

A sleeve connecting casing (6) coaxial with the ball journal (7) is fastened to the ball journal (7).

A swivel is pivoted at (42) to the second link.

The fourth connection point is closer to the pivot axis than the second connection point.
