Success Case

 

  

Application case of excavator hose in construction machinery

Widely used in various types of construction machinery such as excavators. It has the characteristics of long life (5 years weather resistance, 2 years warranty), high pressure (25% higher than SAE/DIN standard), pulse resistance, low bending, etc. It is suitable
for excavators and other large construction machinery.

 

Successful Use of Hydraulic Hose Assemblies

When assembling the hose, the recommended insertion depth has not been followed and the fitting has come off. After replacing the hose assembly, before crimping the new hose, mark the outer rubber of the hose according to the insertion depth indicated on our sample, and then insert the hose until the edge of the sleeve aligns
