Abstract

910,818. Endless-chain trench excavators. EBERHARDT, R., EBERHARDT, W., EBERHARDT, A., EBERHARDT, D., [trading as EBERHARDT GEB.]. Feb. 17, 1959 [Feb. 19, 1958], No. 5514/59. Class 68 (1). A digging chain-supporting boom 2 is at the upper end mounted on a tubular shaft 6 so supported in and transversely of the chassis of the machine that the shaft 6 may be rotated about the axis thereof and also at the end remote from the boom about an axis 9 parallel to the longitudinal axis of the machine, these movements of the shaft 6 being controlled so that the boom, when once in a desired position, can be maintained in the position irrespective of the movement of the chassis by feeler devices 63, 93 associated with electrical relay systems operating standard servomotor systems associated with the jacks controlling movement of the boom.
