TR550型旋挖钻机在关键结构件上选用了日本JFE780型高强度钢材、铁路货车专用高强度耐候钢、高强度结构钢钢管等特殊高强度材料,让整机强度有明显提升。上车采用了卡特彼勒大型上装,并选用了德国卓轮减速机与力士乐马达,关键部位的国际化配套能有效提高该机的可靠性。该机采用卷扬加压的加压方式,使得加压力得到有效保证。箱型截面钢板焊接式下桅杆采用高强钢焊接而成.突破了国内同行业在高强钢使用的技术难关,使得整机机械性能大幅提升。大三角
TR550 rotary drilling rig in the selection of the key structural components of Japan’s JFE780-type high-strength steel, high-strength special weathering steel for railway trucks, high strength structural steel pipe and other special high-strength materials, so that machine strength has improved significantly. Caterpillar on the car with a large coat, and the selection of Germany Zhuo round reducer and Rexroth motor, the key parts of the international package can effectively improve the reliability of the aircraft. The machine uses hoist pressurized pressurized way, making the pressure to be effectively guaranteed. Box-type steel welded under mast using high strength steel welded together, breaking the domestic industry in the use of high strength steel technical difficulties, making the machine a substantial increase in mechanical properties.
