The pump cylinders areplaced immediately behind the beam and are similar in opera-tion to a horizontal jack. To adjust the plungerand cylinders to the proper height for work, asocket wrench is used to operate the four ele-vating screws, placed at the four corners of thetruck and all operated at one time by means ofa chain passing around the four sprocket rack and pinion, at the front of the cylinder,forces the ram up to its work, and hydraulicpower is applied by the pump, wh
