Two stage hydraulic tool, lightweight, compact and ideal for working in confined spaces.
   HT 51 develops a crimping force of 6 tons for installing electrical connectors on copper cables up to 500 MCM.
   Spring loaded handles allow the operator to advance the dies with one hand, leaving the other free to position the connector. For ease of operation and comfort of the operator, the tool head rotates 180 degrees.
   The built-in safety valve will by-pass the oil supply when the maximum pressure is reached, and a pressure releasing system can easily be operated at any stage of the compression.
   The isolated version maintains the same range of compression of the non-insulated version.
