Side Breaker – Complete Guide to Side Type Hydraulic Breaker for Excavators
A Side Breaker, also known as a side type hydraulic breaker, is a powerful excavator attachment designed for breaking concrete, rock, asphalt, and reinforced structures. Unlike box-type or top-type breakers, the Side Breaker features a side-mounted design that provides easier maintenance access and a lighter overall structure.
The Side Breaker is widely used in demolition, road construction, mining, quarrying, and foundation engineering projects. It is especially suitable for medium to heavy-duty applications where high impact force and operational reliability are required.
Side-mounted housing structure
High-impact hydraulic piston system
Easy access for maintenance and servicing
Compact and lightweight design
Durable alloy steel chisel
Efficient hydraulic energy transfer
Side Breaker attachments are commonly used for:
Concrete demolition
Road surface breaking
Rock excavation
Foundation removal
Trenching operations
Quarry and mining work
The Side Breaker is ideal for construction sites where performance and serviceability are key priorities.
The side-opening structure allows quick access to internal components, reducing downtime and maintenance costs.
Compared to box-type hydraulic breakers, the Side Breaker has a simpler housing, making it lighter and easier to handle.
Optimized piston and valve systems deliver consistent impact energy for efficient material fragmentation.
Due to its simpler design and lower production cost, the Side Breaker offers excellent value for contractors.
