21.5 kg medium-duty breaker balancing impact power and portability
B47 is a 21.5 kg medium-duty pneumatic breaker for concrete, asphalt, frozen soil and soft rock. Its approximately 76 J impact-energy class gives stronger breaking performance than a light pick while remaining easier to handle than 39–42 kg heavy breakers.
- 21.5 kg body balances maneuverability with medium-duty breaking power
- Approx. 76 J impact-energy class suits concrete, asphalt and soft-rock work
- Lower mass than B87C/TPB90-class breakers improves handling for general demolition

B47 configuration review
Check delivered pressure/flow, hose bore, inlet and coupling standard.
Use the data sheet for the quoted model and configuration.
Pneumatic Impact Design
Working end selected for the task
The retained tool transfers the body’s impact into the material.
Buyer value
A task-specific moil or chisel enquiry can identify the required tool form as well as the body.
Selection condition
Material and access must suit the selected duty and working tool.
Complete air-line specification
Pressure and flow reach the breaker through the hose and couplings.
Buyer value
Recording the site arrangement supports a usable body-and-air-system match.
Selection condition
Do not infer actual output from a model number or nominal compressor rating.
Configuration-specific quotation
The B47 enquiry is identified by its catalog model/family and the requested connection, application and supply scope.
Buyer value
The written offer can return a reviewable part/configuration identity and itemized supply list.
Selection condition
A model or page reference is not itself a complete order code; approve the offered configuration before ordering.
Application Scenarios
- Material breaking or chipping selected to the identified tool duty
- Road, construction, stone or mining removal enquiries after matching the material and work position
- Fleet replacement enquiries with the exact model and existing tool dimensions

Quality and Pre-Shipment Checks
01
B47 identity and configuration check
Acceptance requirement: compare the offered item with the approved model/part/drawing revision.
This is an order-inspection requirement, not a completed inspection result or certification statement.
Agree checks covering exact model and revision; material and removal/breaking task; working direction and access; tool shank shape and dimensions before order release.
02
Interface and functional evidence
Acceptance requirement: agree the relevant dimensional and, where applicable, functional verification for the quoted configuration.
No test outcome or universal performance figure is claimed. The test arrangement and pass criteria must be tied to the actual offered item.
Use the agreed pneumatic pick / breaker drawing/data sheet and record the relevant connection, fit or operating conditions.
03
Supply, quantity and packing reconciliation
Acceptance requirement: match each delivered line item to the approved supply scope and packing list.
The required marks, protection and document scope must be written in the order.
Check item identification, quantity, visible condition and the agreed packaging/documentation.

Frequently Asked Questions
How much does the B47 weigh?
The established B47 model weight is 21.5 kg.
What impact performance does the B47 provide?
Current references consistently place the B47 around the 76 J impact-energy class and about 21–21.6 Hz, commonly expressed as roughly 1,400 blows per minute.
How much air does the B47 consume?
Published references vary from about 23 to 28 L/s. Use this range for preliminary compressor matching and confirm the supplied configuration in the quotation.
What shank size does the B47 use?
25 × 108 mm is the common B47 configuration. Replacement tooling should still be matched to the actual retainer and shank on the breaker.
What working air pressure does the B47 use?
Use approximately 0.5 MPa as the preliminary working-pressure reference.
What applications suit the B47?
The B47 is suited to concrete demolition, road and asphalt breaking, frozen-soil excavation, soft-rock breaking and general construction or utility work.
What should I send for a B47 quotation?
Send the material to be broken, working position, required chisel, compressor pressure and airflow, hose length, quantity and destination. For replacement orders, include current shank dimensions or interface photos.
Required Air and Tool Interfaces
Match the chisel to the supplied retainer and shank; 25 × 108 mm is the common reference. Use about 0.5 MPa working pressure and 23–28 L/s air demand as preliminary compressor-matching values, then account for hose losses.
