Dozer-blade Cylinders

The dozer blade is an attachment on mobile excavators. The dozer blade is also used as a support to improve the stability of the excavator. Two hydraulic cylinders bring the blade into the support position. Integral check valves provide leak-free shut-off and offer pipe rupture protection. In a similar manner, when the dozer blade is in the raised position a check valve prevents it from sinking.
