ABSTRACT:
A soil compacting device has a vibrator unit dependent from a follower tube and so connected thereto as to be able to swing transversely relative to the tube. The connection is effected by at least one internally disposed flexible tension element such as a rope or cable. A resilient sleeve forms a seal between the adjacent ends of the vibrator unit and the follower tube and restrains relative rotation therebetween. The sleeve is pre-compressed by the tension in the wire or rope. The vibrator unit, sealing sleeve and follower tube form an elongated cylinder-like assembly with a substantially uniform cross-section.
