This mod adds a new item to the game: Chest Transporter. This item allows you pick up a chest with its items and place it somewhere else. You can also pick up chests from a storage minecart and place it in a normal minecart. But while you have a chest in your inventory, you dig and walk slowlier, have more hunger and can not jump over one block. The mod is compatible with Multi Page Chest, Iron Chests, CompactStorage, Iron Chest Minecarts, Storage Drawers, Actually Additions, BiblioCraft, Quark chests and iron chests from Fluidity. You can also pick up mob spawners (can be disabled).
You are allowed to include the mod in a modpack if you give visible credit to me (CubeX2).
