A hand truck utilizes a pair of permanent magnet unit to secure two metallic cylindrical objects to the hand truck. Each permanent magnet unit has a forward-facing clamping surface for engaging a side of a metallic cylindrical object. Each permanent magnet provides a selective magnetic field sufficient to secure the metallic cylindrical object to the forward-facing clamping surface of the permanent magnet. The pair of permanent magnet units may be simultaneously actuated by operation of a single actuation handle. The hand truck may be equipped with a pair of cylinder safety mechanisms by which an operator may selectively engage a safety plate beneath each of the metallic cylindrical objects. Each safety plate is independently rotatable by the operator thereby allowing each metallic cylindrical object to be separately released from the hand truck.

Systems, methods, and apparatuses are disclosed for locking mechanisms to secure multiple cart components. Example embodiments may include a cart with a lower platform, an upper platform, a first storage area disposed between the lower platform and the upper platform, and a second storage area disposed adjacent to the upper platform. Some embodiments may include a door configured to secure the first storage area, where the door is configured to rotate outwards with respect to the upper platform, a hatch configured to secure the second storage area, where the hatch is configured to rotate upwards with respect to the upper platform, and a locking mechanism coupled to the upper platform and configured to lock both the hatch and the door in a locked position. Unlocking the locking mechanism can unlock both the first access panel and the second access panel.
