The Condux Fiber Optic Cable Puller is a hydraulic pulling machine designed for fiber optic
cable placement. It offers bi-directional pulling and load-sensing capabilities. The system
uses a hydraulic motor and capstan with an electronic tension control system.
The tension control system uses an electronic load cell to measure the actual torque at
the puller’s motor. Combining this torque value with the capstan’s diameter ensures accu-
rate tension monitoring. The system’s design gives the operator complete control over the
equipment. It can be set to a maximum tension limit that will stop the puller and give both
audible and visual alarms if the tension limit is exceeded during the pull.
A digital chart recorder continuously records the pulling tensions during operation. The
power pack or the vehicle’s 12 Volt DC power point energizes the electronic tension
control system.
The puller comes standard with a variable speed foot control and hoses to the puller motor,
an adjustable flow control valve for adjusting maximum pulling speed, and a manually
adjustable pressure relief valve for adjusting the maximum pressure supplied to the
hydraulic motor.
