silenced type hydraulic hammers

BLT-280 Heavy Demolition Rock Breaker for 120-350 ton Skid Loaders

Beilite BLT-280 Sound Surpressed Hydraulic Breaker for 120~350 tons Excavators | Loaders | Backhoes | Advanced Low-Noise Technology

Product Overview
The Beilite BLT-280 represents the forefront of silenced type hydraulic breaker or rock breaker technology, engineered with proprietary MIC shock absorption. Featuring a specialized shock-absorbing shell constructed from high-tech composite materials, this hydraulic hammer delivers dual benefits: significant noise reduction during demolition work and minimized vibration transfer to host machinery. Designed for environmentally conscious construction, the BLT-280 is the preferred solution for modern urban, mining, underwater, and tunnel demolition projects.

Key Features
