A surface mining and testing apparatus and system provides for the adaptation of a surface miner to the specific geological conditions of a new area of use. The special features of the surface miner are the arrangement of the milling roller (5) in front of the chassis (1) in the direction of mining,
A surface mining and testing apparatus and system provides for the adaptation of a surface miner to the specific geological conditions of a new area of use. The special features of the surface miner are the arrangement of the milling roller (5) in front of the chassis (1) in the direction of mining, the undershot direction of rotation of the milling roller (5), as well as the adjustability of the milling roller (5) in its height and transverse slope in relation to the level. These functional features are accomplished with the testing apparatus in order to obtain the same kinematic conditions as in the surface miner. To make it possible to extrapolate the results obtained with the testing apparatus to the surface miner, the parameters overall weight, drive output and throughput of the testing apparatus are used as constant, lower ratios in relation to the surface miner. The circumferential velocity of the cutting tools (13) and the force acting on each of the individual cutting tools (13) shall be equal in the testing apparatus and the surface miner. To achieve this, the velocity of travel of the apparatus, which is also the rate of feed, as well as the speed of rotation of the roller, which determines the circumferential velocity of the cutting tools (13), which is also the cutting speed at the same time, are variable. Since the testing apparatus is substantially smaller than the surface miner and the changing of relevant parameters of the apparatus is simpler, costs are saved during the technical adaptation of the surface miner to the specific geological conditions of the site of use.

The dual row outdoor leisure rocking chair of claim 1, wherein the top bracket has a coupling section to fasten with each other in a male and female coupling fashion. 7. The dual row outdoor leisure rocking chair of claim 1, wherein the top bracket has a transverse top stretcher bridged therebetween, the top stretcher being fastened by a fastening element. 8. The dual row outdoor leisure rocking chair of claim 1, wherein the top bracket being covered by a waterproof canvas canopy. 2, wherein said fixed body members comprise at least one central member of an indo-skeletal structure that abuts a pair of said safety beam lower elements and a pair of said safety beam upper elements, and thereby resists, lateral forces from compressive loads incurred by at least one of said safety beam lower elements and at least one of said safety beam upper elements during impact. 13. The vehicle structure of claim 2, further comprising a construction of said vehicle with minimal components for resistance to lateral collisions except for safety zones, said safety zones being the areas of which are covered by said shock absorbing devices and force distributing protector shields, thereby reducing the mass and resulting weight of the vehicle. 14. The vehicle structure of claim 2, further comprising a compressive load bearing auxiliary beams mounted in the vicinity of the passenger seat(s) to increase the compressive load bearing capability of the structure. 15. The vehicle structure of claim 2, where said protector shields include vertical extensions that protrude vertically above the protector shield and shock absorbing devices to provide resistance to lateral forces at higher physical levels thereby providing further protection to the passengers, and to provide a rigid member that can resist vertical forces adequate to support said vehicle in a roll over situation, thereby protecting said passengers. 16. The vehicle structure of claim 15, further comprising a lateral beam across the top of the vehicle that engages said vertical extension when said element of the safety beam upper element set is in said operating position, to provide a safety cage, thereby providing greater side impact protection and protection in a roll over situation. 17. The vehicle structure of claim 15, wherein said vertical extension
