Offering high performance, HİDROMEK's new H4 Series excavators stand out with their operating speed. By changing the diameter of hydraulic cylinders, tubes and bars, the working speed of H4 Series has been increased. The power boost and the maximum hydraulic system pressure have been improved to reach out the required power as well. These improvements have led to create faster, more productive and efficient machines. Earning is more now than ever with H4 Series, which produces more work with less fuel.
During the design process with the aim of rendering the use of the machine easier for the operator, H4 Series has an electronic system with an increased capacity facilitating to find out the condition of the machine and its integration with additional equipment. H4 cabins are designed and built to offer maximum safety and durability under ROPS & FOPS standards.
