MSD supplies hydraulic DTH hammer breakout benches for 3–12 inch DTH hammers, with three size ranges for controlled removal of top subs, driver chucks, and threaded connections during workshop maintenance.
MSD supplies DTH hammer breakout benches for the controlled disassembly and workshop maintenance of 3–12 inch DTH hammers. The available ranges are 3–6 Inch, 6–8 Inch, and 8–12 Inch, with different overall dimensions, hydraulic tank capacities, and machine weights. Because the nominal size ranges overlap, final selection should be based on the actual outside diameter of the DTH hammer, the component to be removed, and the required fixture configuration. Please provide the hammer brand, exact model, outside diameter, and maintenance requirements for compatibility review before ordering.
| Model | Applicable DTH Hammer Size | Overall Dimensions (L × W × H) | Hydraulic Tank Capacity | Net Weight |
|---|---|---|---|---|
| 3"–6" Breakout Bench | 3"–6" | 820 × 850 × 1000 mm | 40 L | 400 kg |
| 6"–8" Breakout Bench | 6"–8" | 1320 × 920 × 920 mm | 70 L | 690 kg |
| 8"–12" Breakout Bench | 8"–12" | 1400 × 1140 × 1180 mm | 70 L | 820 kg |

Read MoreA DTH hammer breakout bench is a hydraulic workshop machine used to secure a DTH hammer and apply controlled force when loosening tight threaded connections. It is commonly used during inspection and maintenance when the top sub, driver chuck, or another threaded hammer connection is difficult to loosen.
The shortened term DTH breakout bench may also be used for this equipment. The bench provides a fixed servicing platform and a purpose-built arrangement for positioning the hammer and the threaded component being removed.
Final compatibility depends on the actual DTH hammer outside diameter, hammer construction, threaded component, and fixture configuration. Nominal hammer size alone is not sufficient to confirm the correct bench.
DTH hammer threaded connections operate under repeated percussion, rotation, and mechanical loading during drilling. After extended operation, the top sub, driver chuck, or another threaded joint may become difficult to loosen, particularly when the hammer is opened for internal inspection, cleaning, lubrication, or component replacement.
Because DTH hammers are heavy and their threaded joints may be tightly loaded, maintenance requires suitable holding and lifting arrangements. A purpose-built hammer breakout bench supports controlled workshop disassembly by holding the hammer in the required servicing position while force is applied to the selected threaded connection.
The breakout bench does not replace correct hammer identification, suitable fixtures, or approved maintenance procedures. The hammer model and the component to be removed must be confirmed before the servicing setup is selected.
The DTH hammer is positioned on the bench and secured using the fixture arrangement selected for the hammer body and the threaded component. The hydraulic system then applies controlled force to loosen the connection so the component can be removed for further maintenance.
The exact positioning and fixture arrangement vary according to the hammer design, outside diameter, and component being removed. The required fixture configuration should therefore be confirmed for the exact hammer and maintenance task.
Operators should follow the machine instructions and the applicable DTH hammer maintenance procedure. The product page provides general equipment information and should not be treated as a replacement for the machine manual or site safety rules.
MSD supplies three hydraulic breakout bench ranges for DTH hammers: 3–6 Inch, 6–8 Inch, and 8–12 Inch. Their overall dimensions, hydraulic tank capacities, and net weights differ according to the intended hammer range and machine configuration.
The nominal ranges overlap at 6 Inch and 8 Inch. A 6 Inch or 8 Inch hammer should therefore not be matched to a bench from the nominal size label alone. Final selection should consider the actual hammer outside diameter, exact hammer model, component to be removed, fixture requirements, and available workshop space.
The listed machine dimensions and weights are also important for workshop layout, lifting, handling, and installation planning. Any special servicing or fixture requirement should be reviewed before production or ordering.
A DTH hammer breakout bench is intended for trained maintenance personnel working in a fixed repair workshop or a properly prepared service area with sufficient operating space and suitable lifting equipment.
The hammer must be correctly positioned and secured before hydraulic force is applied. Personnel should remain clear of loaded and moving parts, use suitable lifting equipment for heavy hammers, wear the required personal protective equipment, and follow the machine manual and site safety procedures.
For selection or a quotation, provide the DTH hammer brand, exact model, nominal size, actual outside diameter, component to be removed, expected maintenance requirements, available workshop space, lifting conditions, required fixture configuration, and quantity. Any special installation or site constraints should also be supplied where applicable.
MSD can review the information provided and help confirm a suitable standard or customized DTH hammer breakout bench configuration. Final compatibility remains subject to technical evaluation and production confirmation.
