## Abstract

A conveyor apparatus with a plurality of transport units movable along a guide means, on the upper side of said transport units there being provided in each case a pusher means which can be driven contrary to a direction of travel of the transport units so that unit load items can be picked up and/or discharged gently.

## Claims

### Claim 1

A conveyor apparatus with a plurality of transport units movable along a guide means, on an upper side of said transport units there being provided in each case a pusher means which can be driven contrary to a direction of travel of the transport units so that unit load items can be picked up and/or discharged so that the unit load items drop vertically down into a receiving means with substantially no relative horizontal speed, characterised in that the pusher means is drivable at a pushing speed which is at least as great as a speed of travel of the transport means concerned.

### Claim 2 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that the pusher means is designed as a pusher, belt conveyor or roller table.

### Claim 3 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that a conveyor surface of the pusher means is arranged parallel to the direction of travel.

### Claim 4 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that the transport units are arranged spaced apart from one another in the direction of travel, by a distance which corresponds at least to a longitudinal dimension of a unit load item to be transported.

### Claim 5 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that a conveyor surface of the pusher means is arranged at an upward slope, seen in the direction of travel.

### Claim 6 (depends on 5)

The conveyor apparatus as claimed in claim 5, characterised in that the transport units are arranged spaced apart from one another in the direction of travel, by a distance which is smaller than a longitudinal dimension of the unit load items to be transported.

### Claim 7 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that a conveyor surface is arranged at a downward slope, seen in the direction of travel.

### Claim 8 (depends on 7)

The conveyor apparatus as claimed in claim 7, characterised in that the transport units are arranged spaced apart from one another in the direction of travel, by a distance which is greater than a longitudinal dimension of a unit load item to be transported.

### Claim 9 (depends on 5)

The conveyor apparatus as claimed in claim 5, characterised in that the conveyor surfaces are arranged sloping at an angle of at least 2°, 5°, 10°, 15°, 20° or 30° to the horizontal.

### Claim 10 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that each transport unit is arranged spaced apart laterally beside the guide means.

### Claim 11 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that two transport units in each case are arranged on either side of the guide means, opposite each other.

### Claim 12 (depends on 1)

The conveyor apparatus as claimed in claim 1, characterised in that the transport units are arranged spaced apart above the guide means.

### Claim 13 (depends on 12)

The apparatus as claimed in claim 12, characterised in that the transport units are arranged on a C-shaped mount, seen in the direction of travel.

### Claim 14 (depends on 12)

The apparatus as claimed in claim 12, characterised in that a receiving means is arranged in a gap between the guide means and the transport units.

### Claim 15 (depends on 1)

The apparatus as claimed in claim 1, characterised in that the transport units are arranged spaced apart beneath the guide means.
