The U-MAD TMA is mounted on a truck chassis with a uniform clearance of 11 \n to 13 inches (28 to 33 cm) between the bottom of the cartridge and the roadway. \n 2. All welds on the U-MAD TMA have been made by certified welders. \n 3. All exposed steel and aluminum surfaces of the U-MAD TMA will be primed and \n painted. \n 4. The U-MAD TMA and support structure in the up position have a total height of \n 8’ 3” (2.5 m). \n 5. A 12 volt or 24 volt preassembled and mounted hydraulic system will be provided \n to raise/lower the TMA from 0° to 90°. This comes standard with locking pins to \n manually lock the system when in the up position. \n 6. Optional support structures are available when clearance is required for truck salt \n spreading units, long truck decks, and other equipment. \n 7. All cartridges will be approximately 90” (229 cm) in width to protect the support \n vehicle and errant motorist. \n 8. The U-MAD TMA rests upon the support structure when in the up position to \n significantly reduce wear and tear from the riggers of travel. \n 9. All standard U-MAD TMAs shall have a complete cab control box for lifting and \n lowering of units. \n 10. All U-MAD TMAs are to be equipped with (2) jack units at the front and (2) \n detachable storage stands at the rear of the cushion. \n 11. The U-MAD TMA is subject to a full QC inspection by the manufacturer before \n being shipped.","bbox":{"left":0.176471,"top":0.443136,"width":0.674828,"height":0.38612100000000005}}],"images_bbox":[],"images_bbox_not_text_overlap":[]}
