Abstract
Abstract A ballast-tamping unit includes two pairs of surface tampers fixedly mounted on two legs of two carrier elements. A common crank shaft supports the two carrier elements independently and vibrates the elements upon rotation thereof. The carrier elements move freely in a plane perpendicular to the crankshaft, and the crankshaft is supported for free movement in a plane perpendicular thereto. The unit is vertically adjustably mounted.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
255 words
A moBile apparatus for simultaneously tamping the ballast along each side of a track rail and along each side of a tie between adjacent ties of a track, comprising 1. a ballast-tamping unit associated with each of the rails, and each unit including a. two pairs of vibratory surface tampers, each tamper having a tamping element for surface contact engatement with the ballast, b. two carrier elements each consisting of a crossmember and two legs extending from the cross member, a respective one of the pairs of surface tampers being fixedly mounted on a respective one of the two legs of a respective on of the carrier elements, said carrier elements extending in first parallel planes perpendicular to the track plane, and c. a common support means extending in a second plane perpendicular to the first planes and to the track plane, one of said first and second planes extending in the direction of the track rails and the other one of said planes extending in the direction of the ties, the common support means pivotally supporting the two and in such alignment that each two of said surface tampers are positioned in planes parallel to the second plane whereby the four surface tampers of each ballasttamping unit are positionable along each side of a track rail and along each side of a tie at a point where the rail and the tie intersect carrier elements for free movement in the second plane; and 2. means mounting the support means vertically adjustably on the apparatus.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
10 words
means mounting the support means vertically adjustably on the apparatus.
Claim 5
Dependent Claim
47 words
The mobile apparatus of claim 1, wherein the common support means comprises a common crankshaft extending in said second plane through the two carrier elements for vibrating the two carrier elements and the surface tampers fixedly mounted thereon, the carrier elements being pivotally supported on the crankshaft.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
62 words
The mobile apparatus of claim 2, wherein the support means comprises a main carrier member and an intermediate carrier member, a pivot interconnects the main and intermediate carrier members for pivotally supporting the intermediate carrier member in the second plane, the intermediate carrier member supports the crank shaft, and a drive means is mounted on the intermediate carrier for rotating the crankshaft.
Claim 8
Dependent Claim
69 words
The mobile apparatus of claim 4, wherein the support means mounting means includes a vertical guide mounted on the apparatus intermediate the track rails, the main carrier member is a two-armed bracket, the arms of the bracket extending in opposite directions from the vertical guide towards the track rails, and a respective one of the intermediate carrier members is pivotally mounted on a respective on of the bracket arms.
Claim 9
Dependent Claim
25 words
