Introduction: Building a Fleet for a New Frontier
Launching a marine scrap business demands more than just ambition—it requires the right equipment to handle massive steel structures, barge dismantling, and future vessel servicing. Selecting a crawler crane and excavator suited for this environment involves balancing lifting capacity, hydraulic versatility, service availability, and long-term reliability. This article explores the decision-making process behind acquiring a 100–120 ton crawler crane and a 30-ton class excavator, enriched with field insights, brand comparisons, and practical anecdotes.
Terminology Clarification
In marine scrap environments, the excavator becomes the most critical piece of equipment. It handles everything from pulling steel off barges to loading roll-off containers. Key features to prioritize include:
A contractor in Pennsylvania leased two Case excavators with full-service agreements. Over four years, each unit logged over 4,000 hours with minimal downtime. The predictable cost structure and dealer responsiveness made Case the most economical choice in his fleet, despite initial skepticism.
Crawler Crane Considerations: Lifting with Precision and Power
Selecting a crawler crane for 100–120 ton lifts requires attention to:
An operator noted that “200+ ton crawlers and budget don’t go well together.” While true, strategic planning—such as sourcing used units from reputable auctions or dealers—can bridge the gap. Preemptive maintenance planning and part stocking further reduce long-term costs.
Best Practices for Equipment Acquisition
A startup in Houston began scrapping barges with rented Komatsu and Hitachi machines. While the Komatsu performed well, limited service availability pushed the team toward Case and Deere for permanent acquisitions. The excavator became the cornerstone of operations, used for everything from torch-assisted cuts to loading steel. Eventually, the team planned to add a shear to streamline processing, reflecting a natural evolution in equipment needs.
Final Thoughts: Strategic Equipment Choices Build Sustainable Operations
Starting a marine scrap business demands more than just heavy lifting—it requires smart decisions about equipment that will define workflow, safety, and profitability. By prioritizing service support, hydraulic capability, and operator familiarity, businesses can build a fleet that grows with their ambitions. Whether choosing a crawler crane or a 30-ton excavator, the right machine is more than metal—it’s a partner in progress.

Terminology Clarification
- Crawler Crane: A mobile crane mounted on tracks, capable of lifting heavy loads with stability across uneven terrain.
- Excavator (30-ton class): A hydraulic machine used for digging, lifting, and material handling, typically weighing around 65,000 lbs.
- Hydraulic Thumb: An attachment on the excavator’s stick that allows gripping and manipulating materials.
- Shear Attachment: A hydraulic tool used to cut steel and other materials, often replacing torches in scrap operations.
- Dealer Support: The availability of parts, service technicians, and maintenance programs from local equipment dealers.
In marine scrap environments, the excavator becomes the most critical piece of equipment. It handles everything from pulling steel off barges to loading roll-off containers. Key features to prioritize include:
- Hydraulic Thumb Compatibility
Essential for gripping irregular scrap pieces and improving material handling efficiency.
- Shear Readiness
Machines should support high-flow auxiliary hydraulics to power shears for cutting steel hulls and beams.
- Operator Comfort and Visibility
Cab design affects productivity and safety, especially during precision dismantling.
- Service Access and Reliability
Machines with easy access to filters, pumps, and electronics reduce downtime.
- Komatsu
Praised for durability and smooth controls. However, limited dealer support in some regions can hinder maintenance.
- Hitachi
Known for hydraulic precision and reliability. Popular in scrap operations due to thumb and shear compatibility.
- Case
Offers attractive lease options with full-service packages. Operators report low operating costs over multi-year terms.
- Deere
Strong dealer network and parts availability. Often used interchangeably with Hitachi due to shared components.
- Caterpillar
Reliable and widely supported, though some users find newer models more expensive without proportional performance gains.

Crawler Crane Considerations: Lifting with Precision and Power
Selecting a crawler crane for 100–120 ton lifts requires attention to:
- Load Charts and Boom Configurations
Ensure the crane can handle barge components at required radii and heights.
- Transportability
Modular design and ease of disassembly affect mobilization costs.
- Operator Familiarity
Crane brands often have loyal followings; comfort with controls and feedback loops matters.
- Budget vs. Capability
Larger cranes may exceed budget constraints, but underpowered units risk inefficiency and safety issues.

Best Practices for Equipment Acquisition
- Split Equipment Research by Category
Investigate excavators and cranes separately to avoid conflated priorities.
- Engage Local Operators and Dealers
Field experience and dealer reputation often outweigh spec sheets.
- Attend Equipment Auctions
Events like Ritchie Bros. offer access to brand-name machines at competitive prices.
- Bring a Knowledgeable Technician
Evaluating used equipment requires mechanical insight beyond visual inspection.
- Plan for Attachments Early
Hydraulic thumbs and shears should be factored into initial purchase decisions, not added later.
- Overlooking Dealer Support
A great machine without local service can become a liability.
- Ignoring Attachment Compatibility
Not all excavators support high-flow hydraulics or thumb brackets.
- Underestimating Transport Costs
Moving large cranes or excavators requires permits, escorts, and specialized trailers.
- Skipping Lease Options
Leasing can offer predictable costs and maintenance coverage, especially for new businesses.
