    摘要： A tamping pad includes cutout along the length of the leading edge thereof to support at least one wear-resistant insert rigidly positioned therein. The wear-resistant insert comprises a body having a first side and a second opposed side, first and second opposed major surfaces and first and second opposed shoulders. The first side of the insert body defines a tamping blade leading edge which is arcuate in shape between the opposed shoulders. The arcuate leading edge of the insert body has a radius which defines the length of the arcuate edge to be of a ratio of about 1.3 relative to the width of the carbide insert. Preferably, the plurality of inserts extends end to end along the length of the leading edge of the blade to define the interrupted leading edge of the tamping pad as formed by the curvilinear leading edge of each of the plurality of inserts.

    摘要： The handle of a tie tamper is connected to its vibration generating motor, to which a beater is rigidly fixed to be vibrated thereby, by a combination of a Neidhart damper fixed to one end of the handle, a shackle-link pair fixed at one end to the square shaft of the damper, and an arcuate leaf spring pin-connected at its one end to the link pair and at its other end to the motor and by a two-bar linkage connected at its two ends via Neidhart dampers respectively to an intermediate part of the handle and to the motor, and a balance weight is provided at the pin joint between the two links of the two-bar linkage. This construction greatly reduces the vibration transmitted from the motor to the handle.

    摘要： A hand-held tamper for underfilling ballast of a track. The tamper has a drive motor for the rotation of an unbalance and a tamping shovel fastened to a lower end of a shaft which is joined to the drive motor and has a longitudinal axis. The shovel consists of two shovel halves each joined to the shaft. Each shovel half has an upper shovel part nearer to the drive motor and a lower shovel part positioned at a first angle
