## Abstract

The invention relates to a passenger or load raising aid for ladders (2), ascending ramps, or similar ascending devices, having a lift element (3) that can, for example, be driven by a motorized drive, particularly implemented as an endless cable, that can be connected to a belt system (5) that can be fastened to the person (1) or the load, and having a safety device attached to the belt system (5), implemented, for example, as a fall protection runner (10), secured to the ascending device (2). In order to implement a safe fall protection, the lift element (3) can be decoupled from the belt system (5) depending on the load.

## Claims

### Claim at position 1

-9. (canceled)

### Claim 10

A climb assist for a climbing device, the climb assist comprising:
a driven pulling element;
a belt system to be secured on a person climbing on the climbing device or a load to be raised on the climbing device;
a safety device secured to the climbing device and to the be system;
wherein the pulling element is connected to the belt system by a connection provided with a load-dependent decoupling action.

### Claim 11 (depends on 10)

The climb assist according to claim 10, wherein the driven pulling element is an endless driven cable.

### Claim 12 (depends on 10)

The climb assist according to claim 10, wherein the safety device is a fall arrest slide.

### Claim 13 (depends on 10)

The climb assist according to claim 10, wherein the connection between the pulling element and the belt system comprises a connecting element that has a separation site providing the load-dependent decoupling action.

### Claim 14 (depends on 10)

The climb assist according to claim 10, wherein the safety device comprises a connecting snap hook.

### Claim 15 (depends on 10)

The climb assist according to claim 10, wherein the load-dependent decoupling action is an adhesive connection.

### Claim 16 (depends on 10)

The climb assist according to claim 10, wherein the load-dependent decoupling action is a shock absorbing lanyard with a tear-off seam connection.

### Claim 17 (depends on 10)

The climb assist according to claim 10, wherein the load-dependent decoupling action comprises a shear bolt.

### Claim 18 (depends on 10)

The climb assist according to claim 10, wherein the load-dependent decoupling action is a connection comprising couplings or clamps.

### Claim 19 (depends on 10)

The climb assist according to claim 10, wherein the load-dependent decoupling action is a separable magnet connection.

### Claim 20 (depends on 10)

The climb assist according to claim 10, wherein the load-dependent decoupling action comprises one or more connections selected from a tight hook-and-loop connection, a vacuum connection, a shrink-fit hose connection, and a connection comprising a break-off bolt connection.
