About Us

Phelps Industries, Inc. is a unique company in that our focus is specifically on truck dumpers/tippers. We have been manufacturing our own telescopic cylinders designed specifically for truck dumpers since 1980.

Our philosophy is to build a dumper that is designed to lift the load, as if no product is emptying from the trailer. This means that the dumper is raising its lifting capacity throughout the tilt cycle. Therefore, the supplied motor horsepower, pump output, and cylinders are sized with that service factor taken into consideration. This philosophy leads to a unit with a longer life span and better safety rating, and safety factor.

Our engineering guidelines lead us to use the proper platform construction, larger diameter cylinder sizing and related pivot radius (the distance between the pivot point of the platform and the cylinders attachment points). The pivot radius is an important factor in design because it directly relates to the fatigue rating of the platform. Because we manufacture our own large telescopic cylinders we can set the pivot radius to achieve the desired lifting capacity (weight that a dumping platform can raise) and design life of the dumper. We state this point, because other manufacturers in the market, tend to mention only the platform construction, as though that is the only factor to consider in the entire dumper design. We believe that the longer this pivot radius, along with proper dumper construction, will lower the pressures seen on the hydraulic system and give you platform with less bending moment/better rigidity.

We challenge anyone to compare our finished dumper weigh to our competitors.

Phelps Industries, Inc. has been building dumping platforms for over 40 years, while constantly updating our designs and listening to the input of our clients to improve design. Throughout this period, we have had dumpers that exceed their life span, and are still in use today. This simply reflects on our design philosophy. We have dumpers that are still in use for their applications since the late 1970s and early 1980s.

Phelps Industries does consider itself a custom dumper manufacturer. This also separates Phelps Industries in this niche market. Phelps Industries can fabricate different lengths of dumper platforms.. The lengths of a dumper platform are determined by the length of the trailer or truck and trailer.

We do not tell you what you need, we can build to suit your request. If you feel your need is a bit different and needs certain specifications, we are willing to achieve your request. We can custom build a platform based on a specific need or product that is to be unloaded. We are flexible and purpose driven for every client.

After we manufacture our units, they are “test assembled” in our plant in Little Rock, Arkansas. Others may have their manufacturing outsourced. We welcome visits by clients to view their equipment during the manufacturing process.
