SA-YZ2x40 Hydraulic Tensioner

The machine is suitable to string one or two ropes or bundled conductors with two pairs of bull-wheels with completely independent controls.
The bull-wheel grooves are made up of high resistance interchangeable nylon sectors.
The machine is completely electronically controlled.

About E-Grid                                            Ningbo Eastern Grid Power (E-Grid) is China leader in designing, manufacturing and supplying hydraulic brake tensioners for stringing operations, ideal to allow operations to be carried out with the highest accuracy, speed and safety.
