Mechanics - The difference between tanks and mobile excavators

One likes to think that you can be a lot safer in a 60 ton vehicle. This is a deadly misconception. Anti-tanks-mines (ATM) have been developed to stop and destroy enemy tanks. Mines do this even after the war is over. The destructive force of an ATM can sling a tank through the air like a toy or simply tear it to pieces. Unfortunatly, ATM's can not distinguish between a tank and a schoolbus full of children.
Some organisations use modified tanks that have been adapted for a more humanitarian use. Such vehicles have large ploughs at the front( so called Tiller's), attached in order to dig up and search through the ground up to a depth of 1 metre. If the blade discovers a mine, it is either destroyed or exploded. One of the biggest disadvantages of these machines is undoubtedly their size and weight. Such vehicles could only be used on large areas of agricultured land - not in built-up areas. In addition, they cosume a great deal of fuel and are reasonably temperamental compared to other vehicles.

There are also other machines that are seeningly cheaper and not temperamental or relatively easy to repair. For financial reasons, it is important for us that these vehicles could be supplied in order that they can be used successfully by the people in the crisis regions. This is so that they can be used further, for example in agricultural regions for research so that people can be supported in the long term re-development of their country.

Mobile excavators can be found in every climate on the earth. They can work in 50°C under direct sunlight and also in -50°C in deserts of ice. Jungle environments and areas with high humidity are also possible. Mobile excavators were developed for such work and have been improved in the last few deccades. ATM's are deadly to mobile excavators and their users. This is why, from the outset, they must avoid coming into contact with a so called ATM. So mobile excavators can not be used to search for ATM's. Should an ATM be found and triggered, the majority of the force of the explosion is absorbed by the excavating arm. In the worst case scenario, the arm would be seriously damaged, but the driver would be protected from harm in their armoured cabin.

For the clearance of anti-personnel-mine (APM), they can be used everywhere. They are, for example, outstanding in the removal of wild vegetation, the clearance of rubble and many more obstacles. Excavators, in comparison to tanks, are lightweight. They are more ecomonic to move and easier to obtain spare parts for. The necessary replacements could be delivered by air freight on any working day all over the world. Any metal worker can repair an excavator. For the repair of a tank, a team of specialists would be required.

In order to withstand an exploding mine, how must the equipment be constructed ?

70% of all mines destroy or kill with the shockwave. If the equipment can be developed so that it can withstand the explosive force, then very little will happen too such equipment. The simpler the equipment, the larger the desired effect and thus there is very little damaged after an explosion.

For clearing wild vegetation it is preferable to use a mulcher; this can clear a thickness of up to 15 cm without difficult. With a mulcher on the clearing arm, the driver can safely clear overgrown hedges, bushes and small trees. There are many different possibilities to use mobile excavators. These are just a few examples.
Today the clearance of vegetation is a pethate of deminers. They see it as a great danger as the deminers could overlook a mine, bringing their colleagues into danger. The current method of practise is as follows: every leaf cut away as if with nail scissors. This method is nerve-rocking and extremly tiring.
In our case, the driver would be protected during their work in a bullet proof and shock proof cabin. From here they can control the mulcher hydraulically and clear the vegetation, there would then be less people in direct contact or in danger of coming into contact with a mine.

Machines make humane minesweeping safer !

As there are many different types of mines, the machines must be secured against all types.

Exploding mines or anti-personnel-mines:
These incorporated a strongly shockwave and fragments of earth could also be thrown out.
Danger to the cabin from the shockwave.
Danger to the equipment and vehicle from the shockwave and fragments of earth.

Jumping and fragmentation mines:
These incorporate a smaller shockwave, but steel, iron or glass fragments in varying sizes may be thrown out.
Danger to the Cabin from the Shockwave and projectiles.
Danger to the equipment and vehicle from the shockwave and projectiles.

In general, the equipment should be built so that possible damage can be repaired at the scene without the requirements of specialists and thatcan be simply mended. What does an instrument use that can only be repaired by specialists who have to be flown in in order to repair the damage ?

What does an excavator do after a minefield has been cleared ?

The vehicle remains in the country in order to undertake its primary function (after clearing mines) - to work as construction equipment. The equipment will be modified in Germany, for example through a project with the job centre and in conjunction with "Bagger gegen Minen" and other medium sized enterprises. After that, transportation will be undertaken by small-medium sized transport firms in Germany. The development of the equipment would then be co-ordinated through a project between experienced organisations and my person. As the equipment is introduced, native people in need of work would be trained to use the equipment. When the initial work is completed, the equipment would then be modified by a trained workforce to be used again for construction purposes. Then the excavator can be used for which it was originally designed - to dig irrigation ditches, lay electricity supplies etc.

Conclusion:

A mobile excavator can be deployed in the humanitarian search for mines. These are the advantages of using tanks and not personnel to excavate mines. After the initial task of mine clearing is completed, the machinery can then be used further for humanitarian development. Due to this, there are no transport costs as the machinery remains in the area.
