Abstract

The present invention relates to a safety arrangement for a portable power driven system, such as an ascender/descender arrangement, specifically in relation to safety means for minimizing risks with items rotating during the operation of the power driven system.

Claims (13)

1. A portable power driven system for advancing a rope, the rope extending in a first main direction, the power driven system comprising:

a motor, the motor comprising a drive shaft;

a rope grab configured to receive the rope, the rope grab connected to the drive shaft of the motor for rotation of the rope grab;

a hinged safety arrangement comprising a safety lid configured to be arranged in a closed state to fully cover the rope grab during operation of the power driven system, and to be arranged in an opened state for allowing introduction of the rope to the rope grab, and

an anchoring point adapted to receive an anchoring force, the anchoring force extending in a second direction being essentially opposite to the first main direction, wherein the hinged safety arrangement further comprises a leaver portion connected to and extending in an angle to the safety lid, the anchoring point being arranged at the leaver portion, wherein the safety lid and the leaver portion are arranged essentially perpendicular to each other, whereby the anchoring force when acting on the anchoring point forces the safety lid to its closed state.

2. Portable power driven system according to claim 1 , further comprising a main body for mounting the hinged safety arrangement.

3. Portable power driven system according to claim 1 , wherein the safety lid and the leaver portion are formed from one piece of material.

4. Portable power driven system according to claim 3 , wherein the one piece of material is metal.

5. Portable power driven system according to claim 1 , wherein the leaver portion comprises an elongated pin, the elongated pin provided for receiving the anchoring force.

6. Portable power driven system according to claim 5 , further comprising a safety sling connected to and enclosing a portion of the elongated pin, the safety sling arranged to receive at least one of a maillon, a carabiner, or a rigging plate.

7. Portable power driven system according to claim 1 , wherein the rope grab has a concave form comprising a plurality of ridges for frictionally engaging the rope.

8. Portable power driven system according to claim 1 , wherein the motor is at least one of an internal combustion engine or an electrical motor further comprising a rechargeable battery.

9. Portable power driven system according to claim 1 , further comprising a user interface for operating the motor for allowing rotation of the rope grab in a first and a second direction.
