FIELD: aircraft engineering.
SUBSTANCE: moving part (2) with bed (1) are attached and unlocked at vibratory platform automatically with the help of the system including retainers with reversing geared motors (6) and end switches (15) operating at extreme positions of said moving part to disconnect said geared motors. At unlocking of moving part is gets connected with fixed bed via four bumpers (4). Every said bumper is composed of a cross of four identical twisted steel round wires without pre-tensioning that make cylindrical expansion springs with one ends articulated at the cross centre. Opposite ends of two horizontal springs are connected via frames (3) with said fixed bed while two vertical springs are connected by brackets (5) with platform moving part.
EFFECT: higher efficiency of platform.
