Abstract: A mechanism for transporting a hub is provided. Particularly, a transport mechanism for a pelletizer knife hub is disclosed. The mechanism comprises a clamp for selectively engaging and releasing the shaft of the pelletizer knife hub. The clamp is connected to a support bar. The support bar, in turn, has a hoisting connector for being raised, lowered, and maneuvered by a hoisting system. According to the mechanisms of the present invention, the clamp is rotatable relative to the hoisting system. In one embodiment, a counter-balance to the hub is provided. In another arrangement, the hoisting system supports the hub above the hub for balancing the system.

Abstract: The shelf system of the present invention comprises a tray or wire shelf or rack having double running surfaces on two opposing sides, which in use provide support for said shelf on the runners provided within an oven cavity. The shelf may be placed within an oven and slid over the runners formed on opposite side walls of the surface liner of the oven. Either the top running surface or bottom running surface of the shelf may be supported by a runner on either side of the oven. Therefore the shelf may be placed in the oven where the runner is between the double running surfaces, or the double running surfaces may allow for the placement of the shelf between two runners. Therefore the number of shelf positions within the oven cavity may be up to double that provided in conventional ovens, allowing for a finer adjustment of positioning of the shelf within an oven.
