Why APPI: Raytheon Company, one of our country’s largest and most experienced aerospace and defense contractors, is the proprietor of the Patriot Missile Anti-Missile System (MIM-104 Patriot). This system’s heart is an independent mobile guidance tower towed into the location on a trailer.

Many nations around the globe now possess the technology required to build and guide intercontinental ballistic missiles – including those with nuclear warheads. The capability to intercept and destroy incoming “hostiles” in flight is critical to our national and battlefield defensive strategy. Raytheon Company, one of our country’s largest and most experienced aerospace and defense contractors, is the proprietor of the Patriot Missile (MIM-104 Patriot), which has proven to be among the most effective missile defense systems in production.

What separates the Patriot from most other SAM (surface-to-air missile) systems is its all-encompassing electronic guidance package which manages detection, tracking, and engagement. This system’s heart is an independent mobile guidance towed into the location on a trailer.

The deployment consists of the tower’s four legs using compressed gas cylinders that lock into place to provide a stable and level platform. Due to rigorous maintenance schedules and a lack of space on the trailer for a hydraulic system, Raytheon turned to Allied Power Products Inc. (APPI) in Beaverton, OR for assistance. In addition, Raytheon had worked with APPI on other application-specific winch and hoist solutions. Therefore, Raytheon knew that asking APPI for a positioning hoist to pull the cylinders back into their compressed position when the towers moved would be well within their capabilities.

APPI’s solution was a 1,160-pound capacity positioning hoist mounted at each leg of the tower. To keep the hoists as compact as possible, they were rigged with “four parts of line,” which increased their pulling power to over 4000 pounds while keeping the package as small as possible. In addition, to ensure the highest possible dependability of the system, APPI equipped one of their standard model hoists with custom features that met Raytheon’s stringent operational requirements, including the use of high-tech synthetic rope.

As evidenced by the battery of environmental and performance tests passed before service, the hoists are rugged and reliable. However, compared to the complex electronics of the Patriot System, they are a simple electro-mechanical solution. Still, in the end, they are a critical part of making it possible for the Patriot to do its job.
