During foundation excavation in Zhejiang, the contractor encountered hard granite rock. Pneumatic picks were slow and inefficient, while blasting was strictly prohibited due to nearby residential areas. The project schedule was seriously behind, causing great pressure on the construction team.
Client’s Problems
Hard granite made pneumatic picks extremely slow and labor-intensive
Surrounded by residential areas, blasting was not allowed for safety and noise reasons
Traditional methods could not meet the required progress, putting the project at risk of delay
Our Communication & Solution
Our sales team visited the site and confirmed the granite hardness, working space and noise restrictions. We recommended 6 units of DL130 piston-type hydraulic rock splitters, which work by hydraulic pressure expanding inside pre-drilled holes, splitting the rock safely from the inside without noise, vibration or flying rocks.
We provided a professional layout:
Hole spacing: 2m × 1.5m
Hole depth: 1.5m
Results After Use
With the DL130 rock splitters, the construction team achieved 1000 cubic meters of granite broken per day, far exceeding the capacity of pneumatic picks. The work progressed smoothly, safely and without disturbing residents. The project recovered the delayed schedule and proceeded on track.
Why Choose DL130 Piston Rock Splitter
✅ Safe — No blasting, no shockwave, no flying stones
✅ Eco-friendly — No noise, no dust, suitable for residential areas
✅ High efficiency — Large splitting force, breaks hard granite quickly
✅ Flexible — Works in narrow foundation pits
✅ Economical — Low labor cost, fast return on investment
