Cable handling system

摘要

A cable handling system has a cable traction unit having a sequence of cable-driving pulleys, a cable path coiling partially around each one of the cable-driving pulleys in the sequence, the cable traction unit being mounted on a rear portion of the vehicle; a cable accumulator unit mounted on the vehicle, having an cable chamber fixed relative to the vehicle and having an annular cable receiving area between a cylindrical outer wall and a cylindrical inner wall, and a cable channel having a first end communicating with the cable traction unit, and a second end communicating with the annular cable receiving area.

主权项

1. A cable handling system for a vehicle, the cable handling system comprising:
a cable traction unit having a sequence of cable-driving pulleys disposed on a common plane, a cable path coiling partially around each one of the cable-driving pulleys in the sequence, also having two end traction wheels, each one being adjacent to a corresponding endmost one of the cable-driving pulleys in the cable path and movable to press the cable thereagainst for traction, the cable traction unit being mounted on a rear portion of the vehicle, the sequence of cable-driving pulleys also having a plurality of intermediate pulleys between the endmost ones of the cable-driving pulleys in the cable path, wherein the cable path coils around more than half the circumference around each of the intermediate pulleys; a cable accumulator unit mounted on the vehicle, having an cable chamber fixed relative to the vehicle and having an annular cable receiving area between a cylindrical outer wall and a cylindrical inner wall, and a cable channel having a first end communicating with the cable traction unit, and a second end communicating with the annular cable receiving area wherein the cable traction unit has a frame onto which the cable-driving pulleys are rotatably mounted, the frame being connected to a cable force sensor at a front end thereof, further comprising a mount freely connecting the frame to the vehicle, in a manner allowing resistance to the cable force exerted by the sequence of cable-driving pulleys during operation of the system to be transferred to the cable force sensor via the frame.
