Product Description

raulic Post Driver with Open Jacket

The Hydraulic Post Driver with an open-jack (open-center) system is a rugged, high-frequency impact attachment engineered for fast and safe installation of fence posts, signposts, and utility poles. Its open-center hydraulic design ensures direct compatibility with standard flow hydraulic systems on excavators, skid steers, and tractors. The unit operates via a trigger-type control or optional remote valve, delivering consistent striking power through a nitrogen-assisted hydraulic piston—ideal for compacted soil, rocky terrain, and frozen ground.

Key Advantages

Broad compatibility: Open-center valve allows plug-and-play connection to most standard hydraulic power units without complex modifications.

High-speed operation: Delivers up to 1,200–2,300 blows per minute, drastically cutting installation time.

Operator safety: Remote activation keeps the operator away from the drop zone while maintaining precision control.

Low maintenance: Simple internal structure with fewer wear parts reduces long-term service costs.

Drawbacks

System limitation: Not suitable for closed-center hydraulic systems unless an auxiliary valve kit is added.

Noise level: Generates high impact noise (approx. 110–115 dB), requiring mandatory hearing protection on site.
