What is the main difference between mechanical and hydraulic cutters except for their mechanism of action?

Hydraulic cutter is easier to work with, so the main difference is, of course, comfort. In most cases, hydraulic cutters are designed for cutting various copper and alum cables, steel ropes, stranded ropes, and ACSR. A typical sample of this kind of cutter is models made by KBT: НГР-40, НГР-53, НГР-65, НГР-85. Most hydraulic cutters have a guillotine-type working head that has a big operational resource. Mechanical models of cutters can be of smaller size, thus more compact. One more advantage of mechanical models is that you can work with them in almost all weather conditions. At the same time that demands much care, as small particles in the ratchet can cause a break.
