Combilift makes a number of units that would ideally suit your load including one that will still load standard trailer with pallets. I think the reason you are seeing quotes for such large units has to do with your load center and the length of fork required to get proper engagement. Depending on your need for a dedicated or 'universal' machine there are a lot of options out there for you, reach forks could be a big help to you depending on you specific needs.
Feel free to contact me if you want more info or want to discuss the specifics of your specialty handling needs.
