The current disclosure relates to a tank trailer for transporting meat packaging by-products. The tank trailer has a cylindrical body having a sloped rear end. An opening is formed in the sloped rear end, and a gate selectively blocks the opening. A locking mechanism is provided to securely lock the gate to the cylindrical body, thereby sealing the cylindrical body. The sloped rear end forms a chute through which meat by-products can be poured. The chute extends for a distance rearwardly of the trailer's rear wheel assembly.

21. Sludge Containment Vessel and Method for Use in Concert with A Vacuum Truck in Spill Containment Inventor Terrance Terry R. Thomas II Abstract of the Disclosure

The invention provides a heavy-duty door lock (22) adapted for locking a door (10) of an intermodal container (12) comprising an internal lock member (24) arranged within the container (12) so as to lock a door (10) from with inside the container (12), the internal lock member (24) being displaceable between a locked and unlocked position; actuating means (26) arranged within the container (12) for displacing the internal lock member (24) between the locked and unlocked positions; and a locking mechanism (28) including an internal lock (52) which is located within the container (12) and which in a locked position prevents the actuating means (26) from displacing the internal lock member (24), and in an unlocked position allows the actuating means (26) to displace the internal lock member (24); and an external lock (54) which is located on the outside of a door (10) of the container (12) and which operatively displaces the internal lock (52) between the locked and unlocked positions.

A bar lock assembly including a lock rod defining a rotational axis for the bar lock assembly. The lock rod includes a first elongated lock rod portion and a second lock rod portion. A lengthwise section of the second lock rod portion telescopically extends from a first end of said first lock rod portion when the bar lock assembly is in a first condition. The second lock rod portion is substantially retracted within the first lock rod portion when the bar lock assembly is in a second condition. An elongated handle with opposed ends extends from the lock rod. One end of the handle is pivotally connected to the first lock rod portion to effect rotational movements of the bar lock assembly about the rotational axis. The handle moves in a fixed arc about a fixed pivot point whereat the handle is connected to the first lock rod portion. Linkage connected between the handle and the second lock rod portion telescopically moves the second lock rod portion relative to the first lock rod portion in response to pivotal movement of the handle about the first pivot point. To enhance the ergonomics of this bar lock assembly, the linkage and handle are configured such that an included acute angle ranging between about 35 and about 50 is defined between the handle and the longitudinal axis of the bar lock assembly when the bar lock assembly is in the first or locked condition.

An inner lock of a door of a container is provided, in which the door of the container includes: a plurality of locking rods installed on an outer side of the door; a handle formed on the locking rods; a retainer which is coupled to the door and on which the handle is seated; and a handle hatch which is rotatably coupled to an upper side of the retainer and binds or releases the handle, and the inner lock includes a rotation shaft passed through the door and extended to an inner side and an outer side of the container; a plate coupled to the rotation shaft extended to the inner side; a lifting member rotatably coupled to the plate; and a locking bar coupled to a lower side of the lifting member to lock or unlock the door by being fixed to or separated from a lower frame, in which the handle hatch is coupled to the rotation shaft extended to the outer side such that the locking bar is manipulated by rotating the rotation shaft from the outer side of the door.
