Armored and Bullet Proof Vehicles - Using Linear Actuators to lift the windows

In certain parts of the world the need for an Armored car, with Bullet proof capabilities is very real. The challenge with converting a regular vehicle such as a Mercedes G-waggon, into a fully protected vehicle requires a lot of components to be swapped out and beefed up. The other problem is space.  Once you start to increase the window thickness, and add more metal around the door jams, and the rest of the door and other body panels you begin to loose a lot of available space required for opening and closing the windows electronically.  This means even a traditional heavy duty window lift mechanism becomes hard to use, hence why Linear Actuator are mostly used in these types of applications.

 armored Mercedes-Benz G63 AMG and G63 6×6 AMG

In the example above, this Mercedes 6 wheel drive G-Waggon has side windows with Curved ballistic glass with a thickness of around 39mm for the front and rear doors, means the electric window lift mechanism will no longer work. The standard window lift motor is only good for the 4mm thick standard glass, but ballistic glass with a thickness of around 39mm  weighs around 500% more. Armored car manufacturers are now turning to Linear Actuators to do the window lifting for them.

The Linear Actuator choice for each vehicle largely depends on the level of protection required. Lower levels of protection may only require a thinner Bullet proof glass thickness thereby reducing weight allowing for a smaller Linear Actuator to be used. The most popular choice is this type of application is our Deluxe 6" Stroke model it offers a fast 3" per second speed at 100.lbs of force, easy to install thanks to the Clevis fittings on each end that offer a lot of fixture capabilities and enough force to lift a large 50mm thick bullet proof glass window lift.  Longer and shorter strokes are also available but this seems to be the most popular. 

Our Armored Window Door Lifter/Linear Actuator Solutions covers armored vehicles for every level, the most popular being B6 & B7 level.   Armored SUV, Armored sedan cars, Armored Trucks, Armored Tactical Vehicles, Armored Personnel Carriers, all typically use this Actuator.
