A vertically stabilized shelf bracket assembly having at least two support strips on which a plurality of shelf brackets are mounted. The shelving is stabilized in several ways. First, the brackets are provided with a shelf engaging recess. The recess is either designed to provide a tight fit for the shelf, or the recess is provided with a shim for tightening the fit. Second, the brackets are provided with a vertical member which engages the shelves. Preferably, the recess and the vertical member will engage the shelf at opposite ends of the shelf, securing the shelf to the bracket. When the shelf is attached to multiple brackets, the shelf will be prevented from pivoting on the bracket. The shelves can be further stabilized by securing the brackets against vertical displacement. This can be accomplished by securing the shelf brackets to the support strip with a locking pin. With the locking pin in place, the shelf bracket cannot be moved upward. Another way of securing the brackets is to provide a vertical stabilizer, comprising an elongated member, preferably of steel or aluminum, having an arm extending perpendicularly therefrom. The arm will fit tightly into a slot in a support strip. When the arm is in place, the elongated member will be positioned over and in contact with the base of the shelf bracket, so that the bracket cannot be moved upward. The vertical stabilizer will be held in place by the cover which fits over the support strips.

A locking mechanism for locking a tilt frame of a hoist to a vehicle frame comprises a semi-annular ring connected in axial alignment to the hub of a hoist lift arm. The ring is adapted to receive a pin connected to the vehicle frame. An opening is formed in the ring and is sized to permit the pin to pass therethrough. When the lift arm is advanced to a retracted position relative to the vehicle frame the opening is positioned below the pin, such that the tilt frame may be pivoted relative to the base frame. When the lift arm is pivoted out of the retracted position to load and unload a container, the ring extends in overlapping position below the pin to prevent the tilt frame from pivoting relative to the base frame.

A portal access assembly includes an inserter that has a needle, a cap moveable along the length of the needle and an infuser having a cannula through which the needle extends. A safety mechanism inside the cap allows the needle to be moved relative to the cap so long as the shaft of the needle biases against an edge of one of the legs of the mechanism. After the cannula is properly positioned in the implanted port to establish a fluid path between the port and the infuser, the needle is removed by being pulled upwards until it no longer biases the one leg of the mechanism. At which time the safety mechanism fixedly captures the needle inside the cap to prevent the contaminated tip of the needle from being exposed to the environment. At the same time, the cap is detached from the infuser.
