Cable handling apparatus
A feed control assembly for feeding a cable on to a rotatable reel has a primary guide for controlling the location of the cable as it feeds on to the reel, and a drive assembly arranged to reciprocate the primary guide means as the cable feeds through the primary guide.
1. A cable laying vehicle for feeding cable on and off of a rotatable reel as the vehicle travels along the ground, comprising:
a driver's cab;
a tray behind the driver's cab;
a module removably mounted on the tray;
a cable return guide arranged to guide the cable over the cab;
wherein the module comprises:
a mounting assembly for a rotatable shaft;
a rotatable reel offset from the rotatable shaft;
a rolling ring drive mounted on the rotatable shaft for reciprocation along the length of the shaft;
a switch on the rolling ring drive set to reverse the direction of travel of the rolling ring drive along the rotatable shaft when it reaches a stop provided proximate each end of the rotatable shaft;
primary guide means mounted on the rolling ring drive arranged to direct cable passing through the cable return guide onto the rotatable reel;
a stabilizer assembly for preventing the rolling ring drive from rotating with the rotatable shaft; and
a pitch control for setting the length of travel of the rolling ring drive along the rotatable shaft per rotation of the shaft.
2. The cable laying vehicle according to claim 1 wherein the stabilizer assembly comprises a stabilizing bar extending generally parallel to the axis of rotation of the rotatable shaft and a pair of guide wheels connected to the rolling ring drive the guide wheels being arranged to travel lengthwise across top and bottom surfaces of the stabilizing bar.
3. The cable laying vehicle according to claim 1 wherein the module comprises a motor arranged to drive the rotatable reel and the rotatable shaft.
4. The cable laying vehicle according to claim 3 wherein the motor is a hydraulic motor powered through hydraulic fluid lines from a gear pump provided on the tray between the driver's cab and module, the hydraulic motor being arranged to directly drive the rotatable reel through a central shaft which is connected by chain drive to drive the rotatable shaft.
5. The cable laying vehicle according to claim 1 comprising a video camera arranged to provide the driver of the vehicle with a view of the cable unwinding at the back of the vehicle through a screen provided in the cab.
