Shipping a Hydraulic Breaker or Rock Hammer: Transport Guide
Hydraulic breakers — also called rock hammers or demolition hammers — are heavy excavator attachments used for breaking concrete, rock, and frozen ground. These units range from compact 500-pound attachments for mini-excavators to massive 12,000-pound box-style breakers for 50-ton machines. Shipping them requires proper preparation, secure crating or skidding, and the right trailer selection based on the unit's size and weight.
Hydraulic Breaker Weight and Dimension Ranges
Hydraulic breakers are classified by the carrier machine weight class they're designed for. Transport specifications vary widely:
| Carrier Class | Breaker Weight | Approximate Dimensions | Typical Transport Method |
|---|---|---|---|
| Mini-excavator (1–5 ton) | 120–500 lbs | 2'–3' long, 8"–12" wide | Pickup truck, cargo van, LTL freight |
| Small excavator (5–15 ton) | 500–2,000 lbs | 3'–5' long, 12"–18" wide | Flatbed, step deck, LTL with pallet |
| Medium excavator (15–30 ton) | 2,000–5,000 lbs | 5'–7' long, 18"–24" wide | Flatbed, step deck |
| Large excavator (30–50 ton) | 5,000–8,000 lbs | 7'–9' long, 24"–36" wide | Flatbed, lowboy |
| Heavy-duty/mining (50+ ton) | 8,000–12,000+ lbs | 8'–12' long, 36"–48" wide | Lowboy, RGN, specialized trailer |
Pre-Transport Preparation
Proper preparation prevents damage and ensures DOT compliance. Before shipping a hydraulic breaker:
- Disconnect and cap hydraulic lines: Hydraulic fluid leaks during transport can damage other cargo and create environmental liability. Use proper hydraulic caps rated for the system pressure.
- Secure the chisel (working tool): The chisel should be pinned in place or removed and shipped separately. A loose chisel can shift during transport and damage the breaker body.
- Mount on a skid or crate: Breakers should not be shipped lying loose on a trailer. Build or use a purpose-made skid that allows forklift access and provides stable support for the unit.
- Drain nitrogen if required: Some breakers use nitrogen-charged accumulators. Check manufacturer guidelines — some units should be depressurized before transport, others should not.
- Document the condition: Photograph the breaker before loading, including the chisel, mounting bracket, and hydraulic connections. This protects against damage claims.
Trailer Selection
The right trailer depends on the breaker's weight and dimensions:
- Flatbed (48' or 53'): Best for medium to large breakers on skids. Legal height limit is 13'6" including the load. Most breakers on skids fall well within this limit.
- Step deck: Useful when the breaker on its skid exceeds 13'6" total height, or when loading from a dock that's too high for a flatbed.
- LTL freight (palletized): Appropriate for small breakers under 2,000 lbs that are properly crated. Requires accurate weight and dimension data for freight class determination.
- Lowboy or RGN: Rarely needed for breakers alone, but may be used when shipping a breaker alongside the carrier machine it's matched to.
Shipping a Breaker with the Carrier Machine
Many customers ship a hydraulic breaker alongside the excavator or backhoe it's matched to. This is often the most cost-effective approach:
- The breaker can be placed in the excavator's bucket or on the trailer deck alongside the machine
- Ensure the combined weight (machine + breaker + trailer + truck) doesn't push the GVW over permit thresholds
- Secure the breaker independently — don't rely on the machine to hold it in place during transport
- If the breaker is in the bucket, ensure the bucket is curled tight and the boom is in the lowest transport position
Permit Requirements
Most hydraulic breakers shipped on skids or crates fall within legal dimensions and don't require oversize permits. However:
- Very large mining-class breakers (8,000–12,000+ lbs) may require overweight permits when combined with trailer weight
- Breakers shipped with the carrier machine will almost certainly require oversize and overweight permits based on the machine's dimensions
- Breakers with extended chisels or mounting brackets may exceed legal length if not properly prepared for transport

Common questions
Do I need to crate a hydraulic breaker for shipping?
For breakers over 500 lbs, a skid is strongly recommended. A purpose-made skid allows forklift access, provides stable support, and prevents the breaker from rolling or shifting during transport. Full crating is recommended for smaller breakers shipped via LTL freight.
Can I ship a hydraulic breaker in the excavator's bucket?
Yes, this is common practice. Place the breaker in the bucket, curl the bucket tight, and lower the boom to the transport position. Secure the breaker independently with chains or straps — don't rely on the bucket to hold it. Verify the combined weight doesn't push the load over permit thresholds.
Do hydraulic lines need to be capped before shipping?
Yes. Always disconnect and cap hydraulic lines before transport. Hydraulic fluid leaks can damage other cargo, create environmental liability, and may violate DOT hazmat regulations if the fluid is classified as a hazardous material.
How much does it cost to ship a large hydraulic breaker?
Shipping costs depend on the breaker's weight, dimensions, and distance. A large breaker (5,000–8,000 lbs) on a skid shipped 500 miles on a flatbed typically costs $800–$2,500. Contact IronHaul for a specific quote.
Can IronHaul ship a breaker and excavator together?
Yes. We regularly ship excavators with their matched attachments, including hydraulic breakers, thumbs, and couplers. Shipping together is often more cost-effective than two separate moves.
