A bidirectional garbage compactor comprises a compacting chamber which is provided with a first-direction compacting mechanism and a second-direction compacting mechanism.

The tamping mechanism is set at the back of the base (16).

The storage chamber is vertically aligned with the compactor mechanism.

The front end of the tamping mechanism is connected with the back end of the base (16).

A compacting mechanism is fitted to the lid and comprises a compacting plate (22) mounted under the lid and an actuating rod (24) coupled to the compacting plate through an aperture (26) in the lid.

A loading door is formed in an end of the body for receiving refuse from a compactor mechanism.

The opening of the trash chute may be horizontally offset from the vertical alignment of the storage chamber and compactor mechanism.

A filling and supporting hydraulic support with tamping mechanism includes a roof brace (3), a base (16), a prop (19) and a four-bar linkage.

The compacting mechanism shall be operated using the maximum compaction power corresponding to the combination of the highest frequency and the highest possible amplitude for that frequency as declared by the manufacturer

This invention also relates to a device which is used for padding ground below a duct (1) and comprises a device (106) for hanging a soil-compacting mechanism (103) to the vehicle (6).

The compacting mechanism shall be operated using the maximum compaction power corresponding to the combination of the highest frequency and the highest possible amplitude for that frequency as declared by the manufacturer

Hydraulic cylinders operate the compacting mechanism, which takes the trash out of the hopper and places it into the body of the truck.
