industry definitions

According to Wikipedia, a heavy hauler is defined as “a very large transporter for moving oversize loads too large for road travel without an escort and special permit…”, but that is only a fraction of what defines Phillips Specialized Heavy Hauling as a business. We offer various services and you may not even understand them all, which is why we’ve decided to explain a bit more of our job to you!


B Train
Two trailers linked together by a fifth wheel; can be up to 26m (85 ft) long.


Used for large items that don’t fit in an enclosed truck; the body of the truck is entirely flat and level, there are no sides or roof.


A part that can be added to flatbeds when you need to carry long, self-supporting loads.


An initialism for Removable Gooseneck, also sometimes known as a double drop or detach. It has a gooseneck that detaches and moves away from the trailer’s lower deck.


This is the shaft that connects a pair of tires and on which those tires rotate.


Step Deck Trailer
A specialized version of the flatbed trailer with two different levels of a deck: a bottom and a top. They are designed to carry and haul truckload freight loads that exceed the allowed limits – particularly height restrictions – for the standard flatbed.


A truck body trailer that can be detached from the chassis for loading into a vessel, a rail car or stacked in a container depot.


A frame with wheels and container locking devices in order to secure the container for movement.
