Rope grab device for a portable power driven system

A rope grab device for a portable power driven system, the portable power driven system adapted for advancing a rope, the rope grab device comprising:

• an essentially circular rope grab, wherein the rope grab is adapted to, during operation, engage the rope along at least a section of a circumference of the rope grab and the rope grab comprises a rope engaging face including a concave surface that curves inwards from outer edge flanges, the concave surface is configured to engage the rope and the concave surface includes a plurality of pins adapted to contact the rope along the section of the circumference of the rope grab engaging the rope during operation of the rope grab device,
• a securing device comprising a lever portion, a first roller arranged at one end of the lever portion for guiding an unloaded end of the rope and an anchoring point arranged at the opposite end of the lever portion adapted for receiving an anchoring force from a load connectable to the portable power driven system, wherein the lever portion is attached with a hinged connection arranged between the one end and the opposite end to the rope grab device and is adapted to, by the first roller, exert a pressure to the rope for forcing the rope towards the rope grab at a portion of the section where the rope, during operation, is engaging the rope grab upon applying the anchoring force on the anchoring point,
• a heel portion arranged adjacently to the first roller, the heel portion having a maximum thickness side, whereby the maximum thickness side of the heel portion extends past the outer edge flanges towards the concave surface of the rope engaging face for preventing the rope from re-circling the rope grab, wherein the heel portion comprises:
• a body portion, wherein the body portion extends past the outer edge flanges towards the concave surface of the rope engaging face for preventing the rope from recircling the rope grab;
• and
• a flange portion having a first side and a second side opposite the first side, wherein the first side of the flange portion extends past the outer edge flanges towards the concave surface of the rope engaging face for preventing the rope from re-circling the rope grab, wherein the second side of the flange portion extends away from the rope grab and beyond the body portion, and wherein the body portion and the flange portion together define the maximum thickness side of the heel portion, and
• a second roller for guiding a loaded end of the rope, whereby the rope grab is arranged essentially between at least two of the first roller, the second roller and/or the anchoring point.
