升降工序机械化机具的配套使用是减轻工人劳动强度、节约劳动力、提高升降速度的主要途径。我机自1962年下半年以来,即对拧管机、关门山提引器、简易摆管装置等升降工序机械化机具的配套进行了研究、试验和使用,经过实际应用证明效果良好。 Lifting process The supporting use of mechanized implements is the main way to reduce labor intensity, save labor, and increase and decrease the speed of workers. Since the second half of 1962, the machine has been researching, testing and using the supporting equipment for the screwing machine, the Guanmenshan lifter, and the simple oscillating device, and has proved to be effective after practical application.
