Abstract:
1. A system for stacking distribution transformers for shipping and storage, the system comprising: a first pallet to which a first distribution transformer is attached; a second pallet to which a second distribution transformer is attached; and two vertically extending side supports on opposite sides of the second distribution transformer that support the first pallet above the second pallet, with each side support contacting the second distribution transformer and being attached to the second distribution transformer using a threaded device that is fixedly attached to the second distribution transformer at a lift bolt provision of the second distribution transformer, wherein each side support includes an upper yoke in which a side stringer of the first pallet fits, wherein the side supports directly contact the second pallet such that the side supports are at least partly supported by the second pallet and such that most of the weight of the first distribution transformer is supported directly by the second pallet through the upper yoke and side supports, wherein the upper yoke is a U-shaped piece defining an internal rectangular channel into which the side stringer fits; and the upper yoke is attached to the side stringer with a fastener; and the upper yoke includes a slot around the fastener that allows the side stringer to be removed from the upper yoke without fully removing the fastener.
