Items such as loaves of bread are typically held for transport in a plastic crate. Often such crates are stacked on one another in a factory-bakery, a warehouse, a freight vehicle or a retail outlet. It can be problematic move stacked crates as lifting 5 machinery is often not able to adequately hold on to them. If they are not held securely then crates may drop from the stack, which is inconvenient, not to mention a safety hazard. An object of a preferred form of the invention to address this problem by way of a crate lifter 1 comprising a main support mast 3, a carriage 8 engaged with the mast and rollers 6, 7 that enable the lifter to be moved. The carriage has 10 clamps 9 adapted to move laterally with respect to the mast 3 to grip one or more crates 2 so that the crate(s) can be moved by the carriage up and down the mast. The carriage has a keeper 14 arranged such that it is caused to swing in response to the clamps 9 engaging the crate 2, or the lowest crate to be moved if there is more than one, to bring a ledge 14b of the keeper 14 into engagement with that crate to 15 prevent it dropping free from the carriage.
