How to Ship a Hydraulic Hammer or Breaker Attachment

Hydraulic Hammer Size Classes and Weight Ranges

Hydraulic breakers are classified by impact energy and working weight into three primary categories:

Class	Working Weight	Impact Energy	Typical Carrier Machine
Small	400–1,200 lbs	Up to 1,200 ft-lbs	Mini excavators (1–6 ton)
Medium	1,900–3,700 lbs	1,200–4,000 ft-lbs	Mid-size excavators (6–20 ton)
Large	5,000–7,500 lbs	4,000+ ft-lbs	Large excavators (20–100 ton)

Most hydraulic hammers fall well within standard flatbed or step-deck weight limits when shipped as standalone attachments. However, when shipped mounted on an excavator, the combined weight must be calculated carefully for permit purposes.

Trailer Selection for Hydraulic Hammer Transport

The right trailer depends on whether the hammer is shipped as a standalone attachment or mounted on the carrier machine:

Standalone Attachment Shipping

• Flatbed trailer: Suitable for most small and medium breakers (under 3,700 lbs). The hammer can be blocked and secured on a standard 48' or 53' flatbed.
• Step deck: Preferred for larger breakers or when shipping multiple attachments together. The lower deck height provides better stability for tall, narrow attachments.
• LTL freight: Small breakers (under 1,200 lbs) can sometimes ship via LTL freight on a pallet, though specialized heavy equipment carriers are preferred for proper blocking and securement.

Mounted on Excavator

• When the hammer is mounted on the excavator for transport, the combined weight determines trailer selection
• The hammer adds 400–7,500 lbs to the excavator's operating weight — this must be included in permit calculations
• The hammer's position (boom-mounted) affects the overall height of the load; confirm total height before selecting trailer
• Most carriers prefer to ship the hammer detached from the excavator to reduce height and simplify securement

Nitrogen Accumulator Safety

This is the most critical safety consideration when shipping hydraulic hammers. Most medium and large breakers contain a nitrogen accumulator (gas chamber) that maintains operating pressure. Before transport:

• Do NOT depressurize the accumulator unless specifically required by the carrier or DOT regulations — the nitrogen charge is part of the hammer's design and is safe at normal transport pressures
• Confirm the accumulator pressure is within the manufacturer's specified range (typically 1.4–1.6 MPa / 200–230 psi for the gas side)
• Ensure all hydraulic ports are capped with the manufacturer's plugs to prevent contamination and leakage during transport
• The hammer should be positioned with the chisel pointing down or secured in a cradle to prevent accumulator damage
• Inform your carrier that the attachment contains a pressurized nitrogen accumulator so they can document it appropriately

Chisel and Tool Steel Protection

The chisel (moil point or blunt tool) is the most vulnerable component during transport:

• Inspect the chisel for mushrooming or cracking before shipping — damaged chisels should be replaced before transport to prevent further damage
• The chisel should be retracted into the hammer body as far as possible and secured with the retaining pin
• Wrap the exposed chisel tip with rubber or foam padding to prevent contact damage during loading and unloading
• If the chisel is shipped separately, wrap it in heavy-duty foam and secure it to the trailer independently

Tie-Down and Blocking Requirements

Hydraulic hammers have an irregular shape that requires careful blocking and securement:

• Use hardwood blocking (4x4 or 6x6 lumber) to cradle the hammer body and prevent rolling or shifting
• Minimum 4 tie-down chains or straps rated for the hammer's weight, positioned at manufacturer-specified lift points
• Avoid placing chains or straps over hydraulic hose ports, accumulator housing, or the chisel retainer
• For large breakers (5,000–7,500 lbs), use 3/8" or 1/2" grade 70 or grade 80 chain with appropriate binders
• FMCSA requires working load limit (WLL) of tie-downs to equal at least 50% of the cargo weight for articles under 10,000 lbs, and specific requirements for heavier loads

Shipping Hydraulic Hammers with Excavators from Auction

When purchasing an excavator with a hydraulic hammer attachment at auction (Ritchie Bros., IronPlanet, Purple Wave), confirm with the auction yard whether the hammer will be shipped mounted or detached. Most auction yards prefer detached shipping for safety and ease of loading. Ensure the hammer's hydraulic quick-coupler is capped and that all hoses are bundled and secured before the carrier arrives.
