MB Series Multifunction Excavator Breaker

Attachment Introduction
YTCT MB Series Breakers are a versatile range of multi-function hydraulic breakers designed for two main applications: demolition and post driving. Save time and reduce costs—multi-function capability, all in one machine.

Two Function In One Attachment: Post Driver and Breaker

Inter-Change Adapter

Suitable for demolition and post driving. Breaks rock with a chisel tool and drives posts using a post driver cup tool.
 

Less Rebound Force

The side adapter reduces rebound force, decreasing the machine’s workload and improving overall effectiveness.

Box Bracket Protects Main Body

A fully enclosed case shields the main body from rocks and dust.
 

Post Driver Function

The side adapter drives posts vertically, providing a clear view during post driving.

YTCT MB Series Multifunctional Box Breaker

MB Series YTCT breaker features an interchangeable adapter, allowing the operator to easily switch adapters by loosening or tightening the bolts. This design enables the hydraulic breaker to work from either the top or the side, adapting to different job site conditions. It can also be used as a post driver by attaching the post driver chisel tool and connecting your machine with the side adapter.
