A1™ Performance Features You Can Count On!
The Patz A1™ SERIES II Single Auger Silo Unloader adapts to silos 12 to 24 feet
(3.6 - 7.3 m) in diameter.
Each Patz silo unloader is manufactured at our plant in Pound, Wisconsin with these standard features:
 |
Drive ring. Heaviest, reversible ring in the industry! Heavy 7-gauge (4.5 mm) thick steel, 9 foot (2.74 m) diameter (3 section) ring is flanged to the inside for greater strength and is reversible for greater life. Provides maximum stability for proper machine balance in changing silage conditions. | ||||||
 |
 Ring drive gearbox. Power to the drive sprocket is transmitted from a rugged ring drive gearbox that is shaft driven (one motor drive) or motor driven (two motor drive – pictured). The Patz ring drive torque limiter features a farm proven radial-pin design to provide accurate torque release under adverse conditions of hard-packed and frozen silage while protecting the ring and drive system. Shown with cover and guard removed for viewing purposes only! |
||||||
 |
Torque arm and chute pole assembly. Heavy-duty torque arm and chute pole maintain proper position of unloader. Telescoping chute pole and a continuously self-aligning blower cap mean less door changes. | ||||||
 |
Stainless steel auger cover and powder coated high-strength, corrosion-resistant steel sides resist corrosive acids found in silages. Structure designed for added durability and rigidity. | ||||||
 |
 High-performance auger. Massive heavy-duty 10" (254 mm) high-capacity auger is made with 1/4" (6.4 mm) thick flighting. Double flighting at the chipper wheel end of the auger provides smooth operation while removing the hardest packed and frozen materials. |
||||||
 |
Special hardened steel knives aggressively cut through and deliver frozen, hard-packed silage. | ||||||
 |
Chipper wheel. 6 self-sharpening steel knives welded securely to chipper wheel to clean silo wall. | ||||||
 |
Chipper wheel cover reduces feed buildup on top of wall wheels. | ||||||
 |
 Auger drive gearbox. Powerful beveled gears deliver the power to meet the challenge of hard packed or frozen silage. Heavy flanged coupling separates the auger from the gearbox. Synthetic oil in gearbox performs in the coldest environment. |
||||||
 |
Roller chain-driven single-motor drive for a more positive drive. | ||||||
 |
Two 10" (254 mm) diameter wall wheels. Adjustable, long-life heavy-duty polyethylene wall wheels for accurate positioning of chipper wheel. An adjustment bolt on each wheel allows for a more precise setting of wheels. | ||||||
 |
3-point suspension system keeps unloader level, eliminating the need for counterweights. Choice of suspension arms to fit tripods or hexapods. Optional high clearance suspension arms available for hexapods (16'-24' models) to add extra feed storage and lift. | ||||||
 |
3-cable suspension using high-tensile strength aircraft cable, provides the ultimate stability of unloader. Includes the strongest main cable in the industry at 3/8" diameter! | ||||||
 |
 Heavy-duty blower with impeller. 26" (660mm) high capacity blower features 3 cupped, adjustable paddles to deliver high volumes of silage. Paddles feature stainless steel pins and can be mounted fixed or swinging to ease start up. Air intakes into the blower reduce air resistance for more throwing power. Blower band is made of 1/4" (6.4 mm) abrasion-resistant steel for longevity. |
||||||
 |
Blower cap. Thick steel sides and top for maximum life. Includes holders to keep electric cord securely in place along blower cap arch. | ||||||
 |
 Collector Ring. The Patz electrical joint is the best in the industry, unmatched in design for reliability and longevity.
|
||||||
 |
Motors. Choice of single or three phase motors. | ||||||
 |
A1™ SERIES II Quick ID Logo for easy model identification. | ||||||
 |
  Control panel and remote pushbutton station. Required equipment for your safety and convenience. Single phase, single phase rotation control, and three phase control panels available. Allows the operator to control the unloader while servicing and prevents unintentional 'start-up' by others. |
