Before the advent of armored vehicles, moving safely and currency and valuables was achieved either through deception or by force of arms. In the case of deception, a postman in civilian clothes carrying valuables disguised as regular package or a small piece of luggage. The courier traveled as a passenger in public transport, and though he was armed, the initial protection lies in appearing to the average traveler. The main limitation of this method size. In order to protect the large shipments of valuables, and adopt a tall man at gunpoint. The first convoys surrounded herself with the armed forces. The Spanish galleon filled with treasure from the new world Defender. In recent times, stagecoaches had closed but far from impregnable strong boxes of metal and wood, while the guardian "rode shot gun" to ward off thieves. E-rail cars equipped with cabinets and was guarded by heavily armed Government forces. This method always fails was twofold. First, although the goods were relatively safe while largely protected, stealth, eventually they need to be placed in smaller cars, and more prone to move it to its destination. Final. The second problem that no matter how many soldiers guarded, swords, guns and cannons or precious cargo travel, greater power of thieves with swords and guns and cannons or can muster To steal goods. As weapons became more compact and bouncing dead, this became more of a problem.
She was inspired by the first attempts at commercial success of armored trucks of military armoured vehicles in the first world war and after the war, noticeable increase in robberies of payroll clerks And messengers bearing deposits resulting from the need for safer ways to transfer money. In 1920, a Chicago area called delivery on the verge of starting school bus security vehicles converted by attaching steel plates for the lower part of the body and prevent the Windows. This was followed by every bus T model cars filled with armed guards. Built the first armored real business that same year in Minneapolis, Minnesota, the Saint Paul police commander turned private detective Mike Sweeney. Sweeney vehicle design in the service of his country Sweeney Detective Bureau.
The first armored car wearing only body paint on steel plates. You may keep your hardwood truck chassises were built. This ended in 1927 when bury thieves explosives in the road and the truck exploded brink and carrying $ 100 in payroll money. In the 1930s and 40s, manufacturers have experimented with aluminum, which has a clear weight advantage on steel. Found metal fatigue and crack after a short time, and was stopped. In the 1970s fuel shortage around the globe spurred manufacturers of plastic shields attempt a lightweight, smaller, more fuel efficient chassises, but the results were similar to those with Traditional aluminum and steel regained control in the industry.
Chassis
1 production of armored heavy truck chassis delivery starts bare. Chassis with the arrival of an entire drive train (engine and transmission), and suspension systems. Some manufacturers receive chassis with a cab, which they cut. Then reuse many pieces. Others use the structure, which topped only with fenders and hood.
Body
2 body is built from an armored truck, much in the same way you framed home. First, put parts of steel pipes box vertically on the table known as the dance represent the individual wall shape. Then (because the cross section looks like a flat brimmed hat) placed steel bars called channel lengths Hat horizontally at specific intervals across the vertical pipe sections and tack welded to hold them in place. Partitions are used to shorten the pipe and hat rail in some areas to leave spaces that will become the Windows and doors. The process is repeated on the appropriate dance for each wall and roof deck, bulkhead.
3 Meanwhile, forming large sheets of solid steel body panels. The leaves are cut first to correct size of massive hydraulic shears. Then rolled plates cut on a table where they are cut slots for Windows and doors with high-temperature plasma torches. Some manufacturers used welding torches to run, while some use a computer controlled robotic arms to deal with blocks. With this automated system, plans on a computer. Then instructs the computer automatic weapons to cut shapes and dimensions to match the plans. Robotic arms slide vertically along the path overhead to achieve vertical cuts, while the rollers in the table cutting steel slide across the torch route to deal with horizontal cuts. Then rolled plates on different hydraulic presses where formed curves and angles. Once the steel has been cut and shaped in an appropriate form, against the corresponding frame and welded or riveted in place.
4 floor building is lifted on the chassis. For the first time put a sheet of hardwood in the temple ' Rails framework to insulate against vibration. Then put the floor on wood and attached to the hull at several points with a number of clamps on form c. The walls and every sublimity and tack welded structure or temporarily clamped so join the Earth, where you meet. Then put a roof over walls. Once the entire structure has been validated for integrity and discretion, and all joints and welds and welded completely or her hopes.
Internal processing
5 now that the body has given its structure, pieces that will make running an armored truck in place. First, quit depending on door frames and hung on doors and modify for righteousness. Armoured doors hung on hinges in a belt, which extends horizontally across the face of the door to support the weight of the plating. Seal grease fittings contain stops to allow doors to swing smoothly.
6 and then foam insulation Board is pressure in the spaces between body panels for steel pipe. Internal paper is then welded steel or riveted on the tube. Some manufacturers use cloth, fiberglass woven roving in a place called ballistic steel interior. Infused layers woven roving with epoxy and put them in a template form internal panels from the truck. The layers are pressed together in a template and when dry, forming a solid piece.
7 once it has lined the Interior, installed in the barrier that separates the taxi from the cargo area. Then install any shelves, boxes, cabinets in the field of shipping, and attached to the roof vents and ports gun installed in doors.
Finishing
8. the first step in creating an armored truck is to grind down any rough or irregular seams and seal any seams with dam. Then you are ready painted Interior and exterior are sprayed with several layers of adhesives and the primer before being drawn according to customer specifications.
9. once the paint is dry, and power cord (running all the wires in an armored truck through the channel exposed for easy maintenance) truck, heating and ventilation engineers installing air conditioning and heating unit Background. Then, you install glass; install locks. And are the mirrors, bumpers, grill guards, and boards. Soft trim interior like seats and belts, masks, doorknobs and last substitution to avoid damage during the workflow. Finally, the truck is driven to paint separate booth spray the underside with infrastructure corrosion resistant.
