Having used all flavors of shipper over my 17 years as a Fire Commissioner -- and the Fire Dept. deals with a LOT of unusual, unwieldy, heavy shipments for all kinds of Fire tools & implements -- I can say that UPS is near the bottom. FEDEX in my experience much better. But for a heavy shipment that requires LTL (tractor trailer) shipment, there are any numbers of companies that do this, including transportation brokers who will help find the most cost-efficient options. Locally, we use J.B. Hunt, a national shipper, who has a depot about 15 miles fron us. Last 2 times, I used them to ship a fire pump (maybe 400 lbs) and a large air compressor (about 250 lbs).
