Apparatus for covering a land area with a heavy wide width flexible sheeting

Apparatus for covering a large land area with a heavy, wide width, flexible sheeting such as a geotextile clay liner, comprising:

• a main framework shaped, sized and adapted for mounting engagement onto the end of a moveable work arm assembly called a crowd of a powered excavator vehicle;
• a swivel plate assembly rotatably secured to the underside of said main framework;
• an elongated support member fixed at an intermediate section thereof to the underside of said swivel plate assembly for rotation with said swivel plate assembly;
• a downwardly extending bearing arm assembly having a proximate end pivotably fixed to one end section of said support member and a free lower distal end;
• power means engaging said bearing arm at an upper end portion thereof for impressing a moving force on the pivotable bearing arm;
• a downwardly extending bushing assembly pivotably mounted on the other end section of said support member;
• an arbor assembly including an elongated mandrel sized and shaped for receiving and supporting a roll of heavy weight liner sheeting and having one of its ends journalled in said bushing assembly and its opposite end removably arranged in the lower end section of said bearing arm;
• wherein when aid bearing arm is pivoted away from said other end of said support member the mandrel is released from said bearing arm and is pivoted downwardly whereby a roll of heavy sheeting may be placed on said mandrel;
• and when said bearing arm is pivoted toward said opposite end of said mandrel said opposite end of said mandrel is received in said bearing arm;
• removable locking means engageable with said swivel plate assembly for selectively securing said swivel plate from rotation;
• and
• wherein said main framework, said swivel plate assembly, said support member, said support arm, said bearing arm, said power means, said bushing assembly, said arbor assembly, and said mandrel are constructed and arranged such that when said apparatus for covering is lowered toward a land area and the apparatus is moved by an excavation vehicle a roll of heavy sheeting on said mandrel will unroll and the sheeting placed on the surface of the land area.
