9. The apparatus of claim 1 , wherein the first and second extension assemblies are connected to opposing ends of the pressure plate.

10. A method, comprising:

activating a clamp assembly so that a pallet load on a pallet is supported by the clamp assembly, the pallet load in a clamping zone and the pallet in a pallet-receiving zone; and

wherein the clamp assembly includes at least one clamping mechanism having a pressure plate and first and second extension assemblies connected to the pressure plate and independently actuatable to adjust an angle of the pressure plate by advancing a first end of the pressure plate further into the clamping zone than a second end of the pressure plate to secure the pallet load.

11. The method of claim 10 , further wherein, the pallet load comprises product with voids, the pallet load is irregularly shaped, or both.

12. The method of claim 11 , further comprising:

lowering the pallet from the pallet load;

detecting whether the pallet load is securely clamped.

13. The method claim 12 , further comprising:

removing the pallet from the pallet-receiving zone;

moving a different pallet into the pallet-receiving zone;

raising the different pallet to the pallet load; and

deactivating the clamp assembly so that the pallet load is supported by the different pallet.

14. The method of claim 13 , further wherein:

the different pallet has a different pallet load;

during the raising of the different pallet, the different pallet load is raised to the pallet load; and

during the deactivating of the clamp assembly, the pallet load is supported on top of the different pallet load on the different pallet.

15. The method of claim 11 , further comprising:

lowering the pallet from the pallet load;

removing the pallet from the pallet-receiving zone;

moving a different pallet with a different pallet load into the pallet-receiving zone;

raising the different pallet to the pallet load so that the different pallet load is raised to the pallet load;

deactivating the clamp assembly so that the pallet load is supported on top of the different pallet load on the different pallet.

16. The method of claim 10 , wherein the first and second extension assemblies are connected to opposing ends of the pressure plate.
