Hydraulic breaker (hammer) is a heavy construction machinery, installed in excavators, backhoe loaders, skid steer loaders and fixed equipment. It is hydraulically driven to break rocks into smaller sizes or concrete structures into manageable fragments. They are such versatile tools that can handle a wide variety of jobs and come in different sizes and models to meet specific needs.
A good breaker is built durable and is commonly used in a variety of applications such as demolition, construction, road-building, mining and quarrying, tunneling, and landscaping.
