BTI’s large-size BXR Series Hydraulic Breaker Attachments are designed for both speed and strength without compromising longevity. The hydraulic breaker’s blow energy is maximized in varying rock conditions by using recoil-sensing technology with operator actuated two speed control and an oversize piston. This design boosts speed without the need for additional flow to power your productivity.
APPLICATIONS
Primary Demolition // Primary or Secondary Breaking // Concrete Structures // Pavement // Trenching // Tunneling // Underwater

The extra-long stroke pressure balanced piston, oil regeneration system and button-nose piston design maximizes the blow energy needed to break hard rock.
High-strength alloy plate steel with abrasion-resistant plate housing and heat-treated alloy pistons means your rockbreaker will withstand the hard conditions it’s working in.
BTI’s oil regeneration system increases bpms without decreasing energy in harder material applications.
Anti-blank fire on/off selector keeps your rockbreaker from firing until tool force is applied, protecting your internal components from unnecessary damage.
Long/Short stroke selector (manual or remote) optimizes power and speed, giving you options for different applications.
Boxed housing keeps the noise levels down, essential in high-density population areas.

BTI’s BXR Series Hydraulic RockBreakers break-up concrete, aggregate, limestone, hard rock, and granite. To get the best performance from your hydraulic breaker, you need to account for three things: your carrier size, the material your breaking, and your production goals. Your carrier’s operating weight and hydraulic system capabilities determine your breaker size. Use the chart to determine the size range of the rockbreaker, based on your carrier’s weight.
HOW TO USE THIS CHART
If you know the working weight of the carrier you wish to mount the hammer on, you can simply use the chart above to determine which hammer is suitable. Typically there will be two or more choices available. Looking at the chart, to the far right, you can find out the machine working weight in the “Recommended Carrier Range” column. Once you have found it, you can follow across to the left to determine hammer sizes available for your weight range. The working weight of the machine should be substantial enough to form a stable unit with the hammer mounted, but also light enough to prevent overpowering the hammer when raking and maneuvering pieces. Once you have verified which models are comparable to your weight range, you can then check our hydraulic systems capabilities.
PRODUCTION RATES
Based on production rates in cubic yard per eight hour shift.
Note: Values are non-binding industry guidelines by foot-pound class and will vary depending on rock formation, machine, operator and job conditions.
SMALL BREAKERS
Up to 1100-ft.lb. class (1627 Joules), are typically used in concrete and other light duty work.
MEDIUM BREAKERS
1200 - 4000-ft.lb. class (1627 - 5423 Joules) are used in both concrete and rock applications with limitations on the size and amount of material to be broken.
LARGE BREAKERS
Over 4000 ft. Lb. class (5423 Joules), are typically used in hard rock, high production applications.
PRODUCTION RATE MATTERS
The hardness of the materials you’re breaking will identify the right breaker for your job. The material size and hardness plus hydraulic rock breaker size will determine your production flow rate. Use this chart to ensure you’re maximizing your production rate and getting the most from your rock breaker.
BREAKING OVERSIZE
When breaking oversize material the hydraulic breaker is expected to break the material down quickly into multiple pieces. This is optimum production. If the operator has to re-position the breaker towards the edge of the rock and gradually downsize the material, production rate slows down.
To assess which breaker will effectively handle this application, the size and hardness of the material must be known. For example, if a 4 cu. yard piece of hard rock (20,000 psi or greater) needs to be broken in half you require a 7,500-ft. lb. or larger breaker. If a 2 cu.yd. piece of limestone (20,000 psi or less) needs to be broken in half you require a 3,000 - 5,000-ft. lb. hydraulic rock breaker.
The key to getting the highest productivity from your BTI RockBreaker is to choose the right tool for the job. Although there are many types of tools available for your hydraulic rock breaker, the most common tools are the chisel, blunt and moil tools.
