Apparatus, system and method for use within a tank

An apparatus for vacuum cleaning a tank, the apparatus including a main body coupled to a vacuum conduit and a plurality of support legs coupled to the main body,

• wherein the main body includes a main conduit extending lengthwise therethrough and a common central actuator including a movable cylinder fitted about the main conduit, and wherein the vacuum conduit is communication with the main conduit via a vacuum swivel joint,
• wherein the plurality of support legs are operatively coupled to the cylinder of the common central actuator so as to be moveable between a collapsed condition, in which the plurality of support legs are positioned alongside the main conduit so as to allow the main body to pass through an opening of the tank, and an extended condition in which the plurality of support legs are extended within the tank, and
• wherein the vacuum swivel joint is adapted to allow the vacuum conduit to move in a range of motion including a rotational motion of about 360 degrees relative to a vertical axis and a pivotal motion between a lowered position and a raised position.

An apparatus for vacuum cleaning a tank, the apparatus including a main body coupled to a working arm and a plurality of support legs coupled to the main body at a main body pivot points,

• wherein the main body includes a main conduit extending lengthwise therethrough and a common central actuator including a movable cylinder fitted about the main conduit, and the working arm includes a vacuum conduit in fluid communication with the main conduit,
• wherein each of plurality of support legs are operatively coupled to the movable cylinder of the common central actuator by respective struts so as to be simultaneously moveable between a collapsed condition, an intermediate condition, and extended condition, wherein in the collapsed condition the plurality of support legs are positioned alongside the main conduit in a retracted state so as to allow the main body to pass through an opening of the tank, in the intermediate condition the struts support the plurality of support legs in an over centre position relative to the main body pivot points, and in the extended condition in which the plurality of support legs are telescopically extended to an extended state within the tank.
