Field of the Invention
The present invention relates to a method of assembly of a portable track way system. More specifically, the present invention relates to a track way system that is flexible, adjustable so as to be able to align to any ground surface in a way to have the maximum possible contact area with the ground thereby making said track way system capable of carrying heavy loads in a desert.

Background of the invention
Track way systems are employed for the purpose of mobility and supply of ammunition vehicles carrying loads, bridging vehicles and artillery guns. Such tracks are designed so as to be able to bear heavy loads and extreme climatic conditions. There are various kinds of track way systems available all over the globe depending upon the conditions of the place of use of such track.

Such a track has been disclosed in US4488833A. Said track comprises of a plurality of rectangularly shaped planks, each of said planks having a first long side provided with a male portion and a second long side provided with a female portion, said male and female portions of adjacent planks being interengagable; an elongated passage extending along the length of each of said long sides of each of said planks and being generally parallel to said male and female portions; flexible continuous hinge members joining adjacent ones of said planks to each other to form said surfacing system, each of said hinge members having a generally rectangular base portion with first and second bulb portions extending along first and second long sides of said base portion, said first bulb portion of each of said hinge members being removably positionable within said elongated passage adjacent said male portion of a first of said planks and said second bulb portion of each of said hinge members being removably positionable within said elongated passage adjacent said female portion of a second adjacent one of said planks, said hinge member being connectable to said adjacent planks when said planks lie in intersecting planes thereby joining said adjacent planks so that said planks may be folded in an accordion fashion, said flexible continuous hinge members preventing the penetration of water, and the pumping of mud from beneath said modular surfacing and between said adjacent planks during traversal of said modular surfacing system by vehicles when said planks are positioned in substantially the same plane to form said surfacing system; and, hinge retainer means secured in said elongated passages and abutting the ends of said bulb portions of said flexible continuous hinge members to prevent lateral shifting of adjacent ones of said planks in said surfacing system.

Such a mobile platform has been disclosed in US5020411A. Said platform comprises of a plurality of propulsion engines carried by said platform, each of said engines including an array of plasma induction motors, each of said plasma induction motors being coupled to a silicon nitride sintered turbine; energy weapons carried by said platform; programmed control means coupled to said propulsion engines and to said energy weapons for controlling the direction and magnitude of the thrust from said propulsion engines and for firing said energy weapons, all in accordance with an operational program in said programmed control means; and, a source of electrical power carried by said platform and electricity coupled to said propulsion engines, to said energy weapons and to said programmed control means for operating the same.

Detailed description of Drawings

Figures 1-5 illustrate the assembly procedure for lengthening the said track way system and widening the said track way system. The procedure for lengthening of the track involves the following steps:
1. Laying out two singular track parts in such a way that all the sides as numbered 4 are placed to the left and all the sides as numbered 3 are placed to the right;
2. Fitting of the crest shape comprising of 10 crests on side 1 (F1) in the trough shape comprising of 10 troughs on side 2 (F4);
3. Setting the crest shape comprising of 10 crests on side 2 (F3) with the trough shape comprising of 10 troughs on side 1 (F2);
4. Pivot joining of the track parts as described in steps 2 and 3 by way of passing a pin “P1” through the holes in F1 and F3 present in between the two track parts;
5. Preventing the ejection of said pivot pin from either side of the track parts by employing a grub screw at each end; and
6. Repeating steps 1-5 to form track way system of the desired length.

The procedure for widening of the track involves the following steps:
1. Laying the track of the desired length in a manner that side 4 of the track part meets side 3 of the other track part;
2. Repeating the step 1 until desired width of track is obtained;
3. Setting a projection on side 3 (F6) in between a depression on side 4 (F7);
4. Joining the tracks by way of passing a pivot pin “P2” through the hole in between F6 and F7; and
5. Locking the pivot pin “P2” from inserting end by employing grub screw M6

Figure 5 illustrates the packing of the track way system of desired length and width on a spool. The track for the purpose of easy and fast installation and pack-up after use is rolled on the spool comprising spool pins (F9). Said procedure involves the following steps:
1. Sliding the unjointed side of track with F1 and F3 into F9 for anti-slipping track on the spool;
2. Sliding F9 into the open hole on either side 1 or side 2 of the tracks; and
3. Rolling the spool and winding of the track on said spool.

Figure 6 describes the track way system that is a singular part of the modular track which can be joined in any direction (in length or in width) thereby making a track or a mat of any size ranging from 1 meter X 1 meter to any extreme dimensions.

Figure 7 illustrates a Joining Pin P1. Said pin is used to join the track along larger side to increase the length of the track. The length of P1 may depend upon the width of the track. The length of the pin P1 is directly proportional to the length of the track way system. If the said track is 1 meter wide then the length of the pin P1 shall be 1 meter.
Also, a Joining Pin P2 is described in Figure 7 of the invention. Said pin is used to join the track along shorter side to increase the width of the track. The length of pin P2 shall always remain constant that is of dimension 90 mm.

Figure 8 of the invention illustrates an anchoring nail. The track way system is anchored to the ground by a number of anchoring nails. The track is anchored to the ground at every 5 meters of length of the track.
Figure 9 of the invention illustrates a grub screw. Grub screws are used to lock sliding movement of the joining pins P1 and P2. For the purpose of locking of Joining Pin P1, 2 grub screws are employed at each end of the track way system whereas for locking Joining Pin P2 only one grub screw is required.

Figure 10 of the invention illustrates the spool. The track way system is winded on the spool for easy and fast installation of said track. The spool comprises of spool pins (F9) that aids in the rolling and winding of the track on the spool.
