CTHB Hydraulic Breaker – ST Series
CTHB ST series post drivers include rock breaking and posting wood in one unit by simply switching the chisel tool.
When the operator mounts the cup chisel into the hammer, a post driver is all set to help the excavators do the wood/steel/post/ fence tasks on the farm, riverside, and other soft soil ground.
Specially engineered heavy-duty side adaptor and full-closed bracket encase the mainbody and achieve a high degree of rigidity and strength. The impact power is big enough to break rocks, and post wood into the ground for sure.
The interchangeable adaptor can be easily changed between top and side to fit various working condition. The hole diameter and distance are the same between top plate and side adaptor.
