Clement utilized computer "finite element anaylsis (F.E.A.)" to develop an extremely strong, relatively light weight trailer that was quite simple to manufacture. The results of which offer the customer a "workhorse trailer" and long life at a reasonable price.
   Evidence of the strength built into the trailer are the 3/16" HT50 high tensile steel side sheets assuring extended life expectancy when compared to other trailers.  Supporting these heavy duty side sheets
.

are two massive 4" x 6" tube bottom rails with 4" x 6" bracing. 
  Another innovative feature built into the Clement is utilizing the bottom rails as our 80 gallon air tank for the gate, eliminating cost and weight.
   Finally as with all Clement trailers, our foundation is strong and stable with 102" 25,000 pound axles; common inner and outer bearings; a 40,000 pound four-spring suspension as standard with 50,000 pound single point as an option.

The all new Clement JobStar ... loads, fast, hauls more, dumps dependably

8-inch diameter cylinders.

 

 

JobStar's extra heavy-duty timing gear
Front view of the extra heavy-duty timing gear that never needs replacing, adjusting or maintenance. Also illustrated is the positive five-position gate positioning bar.

JobStar's 80-gallon air tank in the bottom rail
Clement's innovative air tank eliminates the weight of an extra tank. At the same time it provides an early warning in the event that this vital member is damaged and requires immediate repair.

The muscle of the JobStar — the hopper
The hopper with 3/16-inch Hiten-50 steel as standard is nearly double that of competitive units, thus you get double the wear. As an option, 3/16-inch AR450 abrasion resistant steel is available to further increase the life
of the trailer.

 

Clement Air Cylinder
Cross Sections and Features

A. Solid aluminum head and cap and black anodized for corrosion resistancee.
B. Piston machined from solid aluminum bar stock
C. Hard anodized ID aluminum tube
D. Lip-type low friction urethane piston seals are pressure-energized.
E. Nitrile O-ring design is pressure compensated and reusable.
F. Rod lip seals with a rod u-cup is completely self conpensating for zero leakage at all pressures.
G. The new wiper wipes dirt out for less maintenance.
H. Piston wear ring is nylon material designed for low friction, and to ensure maximum wear in the cylinder.
I. Bronze gland is externally removable without cylinder disassembly for easy maintenance.
J. Piston rod high steel. Nitrocarburizing treatment on the rod gives better corrosion-resistance properties (outperforms 12-micron (.0005 inches) Chromium electroplating by ratio up to 20:1).
K. Tie rods have corrosion resistant (Nitro carburizing)., stress proof steel.
