Overhead Power Line Hydraulic Pulling Machine Hydraulic Pull Rope Pinch Device
Overhead Power Line Hydraulic Pulling Machine Hydraulic Pull Rope Pinch Device
Our SA-YQ220 Hydraulic Puller features high-security operation, especially when a hydraulic failure occurs resulted from the sudden flameout of motor or other reasons. This is because the spring applied hydraulically released brake can act automatically.
Another striking characteristic lies in its hydraulic type rope clamping device. Owing to it, the steel wire rope reel can be replaced conveniently. With the steel wire rope automatically winding device, our puller is able to arrange the rope by itself as well as load and unload easily.
This SA-YQ220 Hydraulic Puller possesses the overload automatic protection function, so our users can preset the maximum traction force for conductor-stringing operation at random. Both traction force and pulling speed are steplessly adjustable. The pull in the rope can be clearly displayed on the line pull gauge.
