ABSTRACT:
The tamping head on a mobile track tamper includes a pair of rigid tamping tool units each consisting of a T-shaped holder whose vertical arm is mounted on a vertically movable carrier and whose transverse arms each have a tamping tool mounted therein. The tamping tool units are vibrated by an eccentric shaft and reciprocated by hydraulic drives linked to the eccentric shaft and to the vertical arms of the holders, respectively. A housing defining an oil sump in the lower portion thereof is mounted on the carrier and holds the eccentric shaft, and bearings which rotatably mount the eccentric shaft in the housing and link the hydraulic drives to the eccentric shaft being lubricated by the oil from the sump.
