Clement Half-Round Rock Trailers

Its not often you can decrease trailer weight white increasing the strength of the trailer. But that's been done with Clement Rock Trailer half-rounds, the standard against which other trailers are now judged. Whether it's 14-ton boulders in Ohio, 2-ton rip-rap in Texas, or even shot rock in San Diego, California, Rock Trailers Plus have handled the loads with efficiency. They are just as adept at handling more conventional loads like sand and gravel, liquid concrete and asphalt. This outstanding track record is the result of Clement's outstanding engineering and .

the experience gained from thousands of rock trailers in the field.
Multiple applications
The Rock Trailer Plus standard body shell with 45-inch sides, is made of 1/4-inch AR450, a very tough steel that makes the trailer capable of withstanding severe impact loads, as well as normally anticipated loads such as sand, gravel, coal, scrap, demolition, etc. AR450 steel is the highest strength that steel technology can provide: 32 percent greater yield strength and 36 percent greater tensile strength than AR400.

Features that set Clement Rock Trailers Plus apart —

102-inch, 25,000-lb. axles combined with hub-piloted wheels
Proven on hundreds of thousands of trailers, 25,000-lb. axles feature common inner and outer bearings. Combined with parallel spindles, both axle and bearing life are substantially increased. With hub-piloted wheels there are no inner nuts and all nuts have right-hand threads. Maintenance time and costs are reduced.

Dumps with wheels on the ground
The Clement Rock Trailer Plus half round dumps with wheels on the ground for greater stability..

Air-Lift gate with 81-inch opening and larger
The Clement Rock Trailer Plus standard air-lift gate has
a minimum 81-inch opening that improves discharge.
Mud flaps are attached to the tailgate to reduce flap
damage. Barn door tailgates are optional

Clement's inverted cylinder
With an inverted cylinder there's no doghouse to interfere with the load. And since the kingpin is located forward, the bridge length is longer allowing greater gross weight. An inverted cylinder has no ledges where dirt can collect and contaminate the system. Because the cylinder is externally mounted, it is easier to service and faster to remove.
