The spring elements (28, 29) are likewise fastened to the vertical column (26) by means of pipe clamps (42, 43). Through the fastening via pipe clamps (40, 41; 42, 43), the vertical beam (26) designed as a tube and the spring elements (28, 29) can be adjusted continuously in the vertical direction and in the circumferential direction.",
