SA-QY-90 Hydraulic Cable Pulling Stringing Equipment Hydraulic Transmission
Closed hydraulic circuit for step less speed variation in both rotating directions. This machine is provided
with a pull pro-setting system that maintains the pre-set pulling value (also when the speed is reduced
to "0") by automatically adjusting the operation speed according to the friction and unexpected loads
which may occur.
