ERKO offers both hydraulic tools, and mechanical tools. Which of them are considered better? Both types of tools are made with utmost care and guarantee comfortable work. However, we should remember that mechanical tools are designed rather for installation works of low intensity in comparison to the hydraulic tools . In order to perform works of high intensity we choose hydraulic tools.
The most efficient mechanical press allows to crimp tubular terminals and connectors Al on wires with the maximum cross-section to 240 mm2. It should be noted that most of the mechanical crimping tools are designed for crimping cable terminals on wires with significantly smaller cross-sections. For comparison, the hydraulic head GU 625 can crimp cable terminals Cu and Al on wire with the cross-section from 300 mm2 to 625 mm2. The difference is significant. The hydraulic head works with hydraulic units produced by ERKO e.g. pump H 800 and aggregates AH 100, AH 500 and AH 550.
Hydraulic cutting heads
It is also much more efficient and requires less effort to use the hydraulic heads for cutting. In this case, the cable shears, for example RC 100T, can cut the wires with outer diameter up to 100 mm and the cross-section 2×400 mm2. Hand shears are used more often in case of wires with smaller cross-sections. Hydraulic head GC 100 can cut wires with outer diameter up to 96 mm.
When cutting round, square or rectangular holes we ,in most cases, use hydraulic head rather than manual hole punching tool. The head works with different types of punches with bigger sizes. For example WHE 80 hydraulic punching tool works with WO punches from 12,7 -80 mm, WON 12,7 – 32,5 mm, WK 68,5 x 68,5 and WP.
Busbar processing tools
In case of busbar processing we can only talk about hydraulic tools e.g.. bender-puncher HGD 125, busbar cutter HC 125, axial bender HSK 5010 or lateral bender HGP 5010. In most cases we choose to work on busbar processing stations which allow us to perform a complex busbar processing starting from cutting, bending through offsetting and inserting nuts.
