Why can't the spud of Cutter Suction Dredger sink


Recently, some users have repeatedly reported on the Internet that the spud of a small Cutter Suction Dredger they operate cannot be lowered during operation.

Through the joint efforts of editors and technicians, this problem was finally solved. The following describes in detail the reasons why the spud cannot be lowered.

Since the spuds of Cutter Suction Dredgers mainly rely on the hydraulic system for retraction and release, when encountering the problem that the positioning piles cannot be put down, the consumption of hydraulic oil should be carried out first.

If too much oil is consumed, the power of the hydraulic system will be affected to a certain extent, and within a certain limit, the positioning pile may not be retracted and loosened.


Secondly, if the hydraulic oil pump or pipeline leaks, the hydraulic system may fail and the spud cannot be recovered correctly.

Before each operation, carefully check the service condition of oil products and the tightness of pipelines to avoid problems.

In addition, when the Cutter Suction Dredger is used, if it works in a hard soil environment, or there are a large number of stones under the water, it may cause the spud to be unable to loosen.

Therefore, the positioning of positioning piles should be carried out in areas with soft soil.
