Vibrating machine for packing ballast beneath railway sleepers - has vibration reducing connection between motor and handle including three shock absorbers

摘要

The machine has a motor (3) with a long wooden staff (2) attached to it and which vibrates in the ballast under the action of the motor. The motor is connected to the handle (28) by two connections, a leaf spring (5) and a system of connecting rods (10,11) which have a limiting angle of connection between them of less than 180 degrees, the system producing practically no handle vibration. There are three Neidhart shock absorbers, between the handle and the connecting rod (20) fixed to the leaf spring, and at the outside ends of the two connecting rods.
