The paper considers the conditions ensuring the stability of vibratory compactors in cramped urban environment. There are presented classification characteristics of the equipment, special attention is paid to the parameters that are the most important to the study: the magnitude of the centrifugal force, the mass value, availability of reverse movement (reversing plate), the drive type. The authors present the schemes of vibration plates with a vibrator of directional and non-directional action. The mathematical description of the stability of vibrating compactors is offered. The reaction under the drum from the supporting surface is evaluated, as well as the moment of inertia of the sealing part of the vibratory compactor in regard to the axis of the drum in the vibration compaction mode.
