Gravel Trailers: Clam Dump

Unibody design - stronger - lighter - bigger payloads...


Many people think that the auto industry was the first to use the unibody design concept. In actual fact, the concept is much older. It goes back to the days of the Vikings.

Their unibody ships were light enough to navigate hundreds of miles inland, on shallow rivers. They were fast, maneuverable and carried huge cargo loads.

As for strength, those beautiful ships could pretty well take anything the North Atlantic could blow at them.

The Vikings expected a lot from their ships and the unibody design didn't let them down.

Today, contractors expect a lot from their gravel trailers and Castleton's unibody design fills that need. Castleton trailers are tough and rugged, yet clean and sleek in their appearance. They also have good road handling qualities on and off the road.

A Better Clam

There are times, during the road building process, when you don't even want to see the punishment your trailers are getting. However, it's got to be done.
It seems that contractors are depending more and more on trucks and trailers to go and do what tractors and scrapers did in times past.
The Castlton is designed to do the hard hauling and the unibody design helps optimize payload and strength.
If you want to haul sticky clay, goop, gunk, A-base, asphalt, - whatever, wherever, - choose the Castleton clam. It's got an aweful big mouth (55" x 96") with as much ground clearance when it is open as when it is closed. Fewer hang up problems.
To give you extra shock protection, the clam opens against mechanical stop in the full open position.

Electronic Clam Control with "Override" is Standard Equipment


The Castleton electronic clam control is designed to keep you moving. It features a cab contolled panel with open - stop - close and override.
From the cab, the driver can open the gate to an adjustable, preset opening width to dump, then override the preset opening to clean the last bit of asphalt off the gates - without stopping or leaving the cab.
