Dozer-blade Cylinders

Description

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.

Advantages

  • Very reliable anti-leakage features
  • Consistent, temperature-independent, material-friendly damping
  • Visually appealing and robust construction
  • For use under the harshest conditions
  • Low-temperature service
  • Long bearing life
  • Good cost-effectiveness for the customer
