BTI Rock Breakers - civils & demolition

BTI’ breakers are well known for underground and mining applications, but also have growing applications in civil construction and demolition.

The BTI breaker can be fitted, as an attachment onto a suitable hydraulic carrier – from excavators and mini-excavators to TLBs, skid steers and loaders. There are two ranges of BTI breakers – each offering different energy ratings and designed for use on different size carriers. The BX Hydraulic Breaker series includes eight models ranging from an energy rating of 550 Joules for the BX4 to 5 400 Joules for the BX40. They can be fitted onto smaller equipment – carriers up to 20 tons.

The larger BXR Series includes six models ranging from an energy class for the BXR50 of 6 800 Joules to the mighty BXR160 with an energy class of 21 500 Joules.  This series is suitable for 20 – 100-ton carriers.

The machines boast a host of features that enhance speed and efficiency for construction site applications like foundations, trenching and demolition.

A BTI unique feature on the hydraulic breakers is the narrow nose design which enhances visibility as well as minimal over-breaking in trenching applications. The oversized, full length, oval retainer pins on the BX10 through BXR160 have excellent resistance to blank fires and expansive load transfer area to front head. The large tool diameters deliver longer life and superior transmission of impact energy.

All BTI hydraulic breakers feature a high strength alloy plate steel construction with abrasion resistant plating which allows for continuous duty in harsh environments. The noise dampening material used throughout the breaker eliminates metal-to-metal contact, reducing wear and noise. 

Every BTI breaker is fitted with top and bottom isolators to absorb recoil energy. The cryogenically enhanced, heat treated alloy pistons and precise tolerances deliver high breaker efficiencies. The short length, large diameter tie rods with integral vibration dampeners provide an exceptionally strong structure.

The remote air breather is positioned above the main control valve on the BX10 through BXR160 models, which provides easy access and clean air intake and a connection for underwater operation when required.

On the BX10 through BXR160 there are remote grease line connection and hydraulic porting on the power cells that allow for easy accessibility for use with carrier or breaker mounted greasing systems.

BX Series

Looking specifically at the BX Series, Booyse notes that these all have breaker mounted manual high/low stroke selector (BX8-BX40) which improves production capability and the long stroke piston design provides high levels of constant blow energy. 

The pressure balanced piston optimises blows per minute (BPM) and blow energy, while the anti-blank fire on/off selector on the BX8 through the BX40 models alternates modes when operating in varying rock conditions.

On the BX6 and larger models, BTI offers an optional sound dampening to further reduce noise levels, which is especially pertinent in high density population areas.

BRX Series

The BXR Series models are equipped with a two speed hydraulic pilot power control. This controls blow energy in varying material conditions. 

The BRX oil regeneration system increases BPM without decreasing energy in harder material applications and the high volume nitrogen charged accumulator provides constant blow energy and recoil absorption.

The button nose piston design maximises energy transfer to the tool and the anti-blank fire interlock protects front head and retainer pins.

The BXR Series uses recoil sensing technology with operator actuated two-speed control and an oversized piston. “This combination maximises blow energy and BPM under varying rock conditions,” Booyse notes. “For example, in hard rock conditions, the BPM is increased providing up to 80% operating efficiency versus 50% efficiency of a conventional breaker. This translates into maximum production and minimal costs,” he stresses.
