Rexroth Valve Hydraulic Puller Tensioner With Hydraulic Oil Cooling
System
Our SA-YQ40 Hydraulic Puller has an overload automatic protection
function. The maximum traction force for conductor stringing
operation is able to be preset. Another function is the automatic
action of spring applied hydraulically released brake. Owing to it,
our product is safe to be operated, in case that the motor suddenly
turns off, or other reasons cause the hydraulic failure.
In use of this SA-YQ40 Hydraulic Puller, both pulling speed and
traction force are steplessly adjustable. The pull in the rope can
be clearly displayed on the line pull gauge. Moreover, our product
employs the steel wire rope automatically winding device, for
automatic rope arrangement as well as easy loading and unloading.
