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). At the heart of this system is an independent that is towed into 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. This is why the capability to intercept and destroy incoming “hostiles” in flight is so critical to our defensive strategy both nationally and on the battlefield. 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 being made.
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. At the heart of this system is an independent mobile guidance tower that is towed into location on a trailer.
To deploy the tower, its four legs are extended by compressed gas cylinders which then lock into place to provide a stable and level platform. Due to rigorous maintenance schedules and lack of space on the trailer for a hydraulic system, Raytheon turned to Allied Power Products Inc. (APPI) in Beaverton, OR for assistance. Raytheon had worked with APPI on other application specific winch and hoist solutions, and knew that asking them for a positioning hoist could pull the cylinders back into their compressed position when the towers were being 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. 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 – which included the use of high-tech synthetic rope.
As evidenced by the battery of environmental and performance tests passed prior to being put into service, the hoists are both rugged and reliable. Compared to the complex electronics of the Patriot System they are a simple electro-mechanical solution but in the end, they are a critical part of making it possible for the Patriot to do its job.
