Abstract
A rotary concrete mixing drum (16) for a vehicle (10) having a drivetrain (18) for rotating the drum (16) includes a wall (33) having an opening (67) and a hatch cover assembly (37/200) removably closing the opening. The hatch assembly (200) may include a hatch cover (202) coupled to a panel (204) by bolts (212).
Claims76
A concrete mixing truck for transporting concrete from one location to another comprising:
- a chassis including:
- a frame, wheels coupled to the frame, a first power source coupled to the frame, and a first drivetrain coupling the first power source and the wheels;
- a second drivetrain coupled to a second power source;
- and
- a mixing drum coupled to the frame and to the second drivetrain, the drum comprising:
- a wall defining an inner surface and an outer surface and including an opening;
- and
- a hatch cover assembly coupled to the opening, the hatch cover assembly comprising:
- a first member located on a first side of a portion of the wall proximate the opening;
- and
- a second member located on a second side of the portion of the wall proximate the opening, the second member being coupled to the first member;
- wherein when the first member and the second member are coupled, the first member and the second member substantially close and seal the opening.
A heavy duty rotary concrete mixing drum for coupling to a vehicle having a drivetrain for rotating the drum, the drum comprising:
- a wall defining a volume and including an opening;
- a hatch cover assembly releasably coupled to the opening, the hatch cover assembly comprising:
- a first member located on a first side of a portion of the wall proximate the opening;
- a second member located on a second side of the portion of the wall proximate the opening, the second side of the wall being opposite the first side of the wall;
- and
- a coupling member coupling the first panel to the second panel;
- wherein when the first panel and the second panel are coupled together, the first panel and the second panel substantially close and seal the opening.
