Phelps Industries is a family owned business which has been manufacturing materials handling equipment since 1927. The early years focused on pneumatic loading systems. In the early 1970’s Phelps Industries expanded in the manufacturing of truck dumpers, various hoppers and hydraulic power units. Hydraulic telescopic cylinders became a part of our offerings in 1980. At the present time, Phelps Industries has more than 950 dumpers in service all across the United States and 29 other countries around the world.
Phelps Industries has technical staff who have been designing and building the dumpers, hydraulic systems and large telescopic cylinders for over 20 years. The Phelps President, Ivo Phelps, has been designing and building heavy industrial equipment for over 40 years.
Equipment manufactured by Phelps Industries include: Truck Dumpers with a variety of lengths and options; Semi-Portable, and Fully Portable Truck Dumpers; Receiving Hoppers with moving floor (Corn Hopper), drag chain or screw bottom floor options; Portable Landfill Tippers; Reclaimers; Up-ending Container Loaders/Unloaders; Large Telescopic and Rod Cylinders and Hydraulic Power Units designed to meet the application. We also engineer and fabricate custom equipment designed to meet the specialty needs of our customers. Our years of experience in design, development and manufacturing assure you of the finest products at the most competitive prices. Our goals are clear in our company and its’ industry. We manufacture rugged dependable equipment and follow up with comprehensive service.
The Phelps Low Profile Landfill Trailer Tipper is designed for over-the-road transportation, when several major components are unpinned and removed comprising a second trailer load. Tipper is designed to raise itself in front for coupling to a truck/tractor or converter dolly for relocation in the landfill. Time required for in-the-cell relocation is approximately fifteen minutes. This ease of movement is critical to landfill operation to save the costs of long distance pushing of materials away from tipper. All portable landfill tippers utilize a self-contained diesel powered hydraulic power unit.

These models are set on a poured concrete foundation at your plant. We manufacture a variety of different models. Each model is determined by the length and its tilt angle. Our assembly mission is to build a strong rigid platform. This is why the dumper is fabricated 10′-0″ wide by the desired length. This means one large fully welded deck shipped to you. Our standard lengths are 35′. 40′, 45′, 50′, 60′, 65′, 70′ and 75′ which indicates the amount of useable deck. Standard tilt angles are 36, 45, 55, and 63 degrees. The product you are handling will determine the needed tilt angle. This is directly related to the angle of repose of the product. We will be happy to consult with you regarding this, given our experience.
If you would like to know more about specific engineering data, please call or fax in your inquiry. We will discuss your application and the design criteria required. Keep in mind all parameters of your application, length of trailer or truck, gross weight, product handled, and if you would like to back on or drive through the unit. We look forward to designing and supplying the best engineered product to accomplish your task.
Portable Units equipped with axles, wheels and tires are designed for over-the-road transport of complete tipper when several major components and unpinned and removed comprising a second trailer load. Actual tipper is deisgned to be coupled to a truck by king pin arrangement and hauled as a self-contained unit.
Our fully portable units* are offered in different styles. A standard elevated unit utilizes an extended approach ramp. Low Profile design uses short approach ramps for applications with limited space or where an extended approach ramp is not practical.
These portable units may be equipped with either electric or diesel powered hydraulic power units.
A portable unit designed to be moved with less frequency utilizes a subframe only, with the dumper sitting directly onto a flat surface. This unit is portable in that it is fully capable of being moved, yet must be lifted onto a flatbed trailer for transport. These portable units are also offered in both the standard and low-profile types which utilize a simple, shortened approach ramp. The low-profile style portable unit may also be used in combination with a live floor hopper.
Phelps Industries, Inc. offers tilters that can be designed to either load or unload 20 to 40 foot intermodal containers. These can be set up to work with flatbed trailers or a transfer car rail system. The bulkhead retainer, with or without a discharge manifold, can be used to interface with your takeaway system. Our systems are not a “one size fits all”. We will modify our equipment to suit your systems and materials handled. Tilters can be set up to elevate from 30 degrees to 65 degrees. Phelps’ tilters may be permanently affixed to a concrete foundation or equipped with a sub-frame for semi-portable operation on a concrete slab. Tilters may be equipped with a scale system for continuous weighing. Bulk loads delivered in intermodal containers are a step to the future, and we’re here to help.
Our extended arm dumper follows and extended radius over our 4,400 cubic foot hopper for complete unloading. This in turn allows for full turn around for hauler and plant receiving operations.
Several standard live bottom receiving hoppers are available in a variety of holding capacities and discharge rates. All hoppers are available for handling wood chips, bark, wood waste and other bulk materials, such as produce, scrap tires and solid waste. Mechanical and hydraulic drives operate a choice of drag chain or reciprocating floors.
Paper mills and biomass plants that receive bark, hogged fuel and wood waste for energy or paper production have seen a change in the quality of these raw materials. New and existing bark hoppers all have the same coherent problem handling these raw materials regardless of the hopper width or length – bridging inside the hopper or bottlenecking at the metering gate.
This is where the Phelps Backrake comes into play. Like no other device, the Phelps Backrake is designed to break-up this raw material and create a consistent hopper discharge rate. The Backrake is custom fit to virtually all types of truck dump hoppers regardless of the manufacturer.
The Backrake is essentially a set of paddles with spikes that revolve in an upward rotation. It is positioned at the discharge end of the hopper at a specified height above the hopper floor based on the desired discharge rate. The continuous lifting motion of the paddles and cutting action of the spikes breaks up clumps of material allowing a consistent discharge under the rake and out of the hopper.
Phelps specialize in large multiple stage single acting telescopic hydraulic cylinders. They offer a full line of four stage, single acting telescopic cylinders with five standard series of sizes. These range from a smallest (final) moving stage O.D. size of 125mm to 250mm. Phelps Hydraulic Telescopic Cylinders can replace existing telescopic cylinders and retrofit to any existing truck dumper. Phelps Telescopic Cylinders meet or exceed O.E.M. specifications.
Custom Telescopic Cylinders: Phelps’ engineering department can also design and manufacture custom telescopic hydraulic cylinders from one to five stages.
Hydraulic power units , with certain design criteria and circuitry, can be supplied complete. Controls can be arranged to extend a single telescopic cylinder or to operate a series of telescopic cylinders. Reservoir sizes can range from 240lt to 8,000lt.
