1. The trapezoidal steel plate is bent and connected to the top of the column: the trapezoidal steel plate is thickened to ensure that the auxiliary arm runs smoothly and more firmly. 2. Enhanced version of the Trinity auxiliary arm: thickened square tube design, easy to deal with a variety of explosion-proof tire flat tires; Auxiliary arm travel price is high, easy to deal with modified tires. 3. The auxiliary arm gas pipe adopts imported flame-retardant nylon network management, which has high wear resistance and is more durable. 4. Auxiliary arm connection shaft thickening and thickening: thickened iron plate fixed, no tilt no deformation, more durable. 5. Press the lock design 6. Nylon double pressure tire wheel: the internal skeleton structure is more durable, high toughness, the downtilt 25° roller tire pressure effect is more ideal, more convenient to disassemble and install tires. 7. The column and the box integrated connection: the column 980 high, the use of widening and thickening double bending seamless welded steel plate, 65° mechanical principle support, stronger tensile force, to ensure high strength working quality, no tilt no deformation, more durable. 8. The small cylinder is 370 long, and the gas pipe joint is copper. Export standard small cylinder, tensile strength is better, corrosion resistance does not rust. 9. The thickness of 13mm thick with a scale square disk, can be used for a long time, never deformation, safer and more durable. 10. The universal shovel can switch the Angle of the shovel tire at will. The laser cutting integrated lengthened shovel tire arm makes the shovel tire more powerful, and does not deform or break. 11. Classic five-foot, easy maintenance, internal use of a set of control system, protection switch durable, not easy to damage. 12. Explosion-proof export standard oil-water separator 13. The rubber rings inside the five-way valve and the big cylinder and the small cylinder are all imported rubber rings, which are more durable
