Hydraulic pressor is actually a standard hydraulic tool, primarily used for crimp engagement of wires and terminals. Because it is a standard hydraulic tool, it must be equipped with a dedicated wire rope adapter die on the crimping jaws before it can be used to attach the wire rope, making it a closed cutting loop. Because it is a standard hydraulic tool, it must be equipped with a dedicated wire rope adapter die on the crimping jaws before it can be used to attach the wire rope, making it a closed cutting loop. The manual hydraulic pliers produced in China generally use power, lighting, and intermediate connection and end-capping operations during cable installation. There are quick devices inside, which can be automatically adjusted. When spring wire ropes were used in marble mines in the early days, copper joints were used to connect the wire ropes, and a manual mechanical press was also widely used at that time. The structure of this kind of crimping pliers is simpler. The pressing parts of the jaws are made into three butt-jointed circular pressing dies with different diameters. According to the pressing order from large to small, the joints are pressed with the steel wire rope and then the wire rope is connected. Although copper joints are usually softer, most of the stones to be cut are soft marble, limestone or travertine, and spring-type wire ropes are used, so manual mechanical clamps can basically meet the requirements. Now such stone mines still use this kind of crimping pliers, which are characterized by simple structure and low price. The disadvantage is that it is only suitable for crimping of copper joints. For some mechanical presses with replaceable jaws, after the jaws are worn, continue to use by replacing the new jaws. If the jaws and the die are integrated, the press jaws can only be scrapped after wear.
