A heavy hauler is a very large transporter for moving oversize loads too large for road travel without an escort and special permit.
A heavy hauler typically consists of a heavy tractor unit unit and multi-axled lowboy flatbed trailer. Some trailers may have independently steerable wheels, and several might be towed by one or more tractor units in a train.
Self-propelled modular transporters, some featuring a dozen and more self-steering axles with scores of rubber tires to spread out a load, are increasingly being manufactured. The ability of combination and self-propelled heavy haulers to carry loads of 100 tons is not unusual.
This week we have had a Doll 4axe low lower arrive. This is capable of carrying 55t on our CAT 2 Volvo tractor unit. Scroll down to see some images of the new trailer.
