Grove GMK8700 vs. CAT TH1255: Two Machines That Both 'Lift,' and Why That's the Only Thing They Have in Common
Grove GMK8700 vs. CAT TH1255: Two Machines That Both 'Lift,' and Why That's the Only Thing They Have in Common
Every so often a contractor asks us to compare a crane against a telehandler the same way they'd compare two excavators, and the honest answer is that we can't do that — not responsibly, anyway. Grove's GMK8700 is a 700-US-ton all-terrain crane, Manitowoc's flagship. Caterpillar's TH1255 is a 12,000-pound-capacity telehandler built to move pallets and materials around a jobsite. Both machines technically "lift" things. That's close to the only spec they actually share, and pretending otherwise would do you a disservice. What we can do is lay out honestly what each machine is actually for, so you're buying — or financing — the right one.
The Numbers, Side by Side, Without Pretending They're Comparable
The GMK8700 carries a maximum rated capacity of 700 US tons and, with its luffing jib system, can reach up to 351 feet. The TH1255 carries a maximum rated capacity of 12,000 pounds — six US tons — with a maximum lift height around 55 feet. Put plainly: Grove's flagship lifts roughly 117 times more weight than Cat's telehandler, and reaches more than six times higher. These aren't two machines competing for the same job. They're not even in the same conversation on a spec sheet, and any article that tries to score them against each other point-for-point is selling you a false comparison.
What the GMK8700 Is Actually Built to Do
The GMK8700 exists for heavy structural lifts — bridge girders, precast panels, wind turbine components, steel erection on high-rise work — jobs where the load itself can weigh tens or hundreds of tons and the crane needs to reach well past the structure it's working around. Grove's Variable Position Counterweight and CCS 2.0 load-management system let the GMK8700 work configurations that would be impossible or unsafe without precise, continuously recalculated capacity data. This is specialized, project-specific equipment, typically rented or owned by a dedicated crane and rigging business rather than a general contractor's everyday fleet.
What the TH1255 Is Actually Built to Do
The TH1255 exists for the material-handling work that happens on almost every jobsite, every day: moving pallets of block or shingles, setting trusses, placing materials at height on a residential or light-commercial build, loading and unloading delivery trucks. It's built to be driven around a site constantly, operated by a broader range of crew members, and used for dozens of small lifts in a single shift rather than one carefully planned heavy pick. Caterpillar's Next Generation telehandler lineup, which the TH1255 belongs to, focused on cab visibility, controls, and ease of operation — features that matter when a machine gets used all day, every day, rather than for one or two major lifts a year.
The Honest Disclosure: These Solve Different Problems, Not the Same One
If you're trying to decide between a GMK8700 and a TH1255 for the same job, stop — that's almost never the actual decision in front of you. The real question is usually one of these instead: do you need a heavy structural pick that justifies bringing in a specialized crane (rent or buy the GMK8700, or a crane sized appropriately to the load, which for most jobs is nowhere near 700 tons), or do you need a workhorse machine for daily material handling on an active jobsite (the TH1255, or a telehandler sized to your typical pallet weights and reach needs). Very few contractors are weighing these two specific machines against each other, because very few jobs actually call for both at the same decision point.
Where the Comparison Does Make Sense: Planning a Mixed Lift Strategy
The place this comparison genuinely earns its keep is fleet planning for a contractor who does both kinds of work — say, a heavy-highway or structural contractor who needs daily material handling on-site (a telehandler) and occasional heavy picks that require bringing in a crane (rented, or owned if the volume justifies it). Understanding that these are two entirely different capital decisions, with different financing structures, different utilization patterns, and different rent-vs-own math, is the actual value of laying them out side by side. A telehandler is a daily-use asset you likely want to own. A 700-ton all-terrain crane is a specialized asset most contractors are better off renting unless heavy-lift work is a core, recurring part of the business.
Financing Considerations: Why They're Also Different Loans
The financing conversation is as different as the machines. A telehandler like the TH1255 is a relatively standardized asset with a well-established resale market, straightforward for most equipment lenders to underwrite and finance over a typical term. A crane in the GMK8700's class is a far larger capital commitment, with a smaller buyer pool, a longer useful life, and underwriting that benefits from a lender who understands crane-specific utilization and resale patterns — which is exactly the kind of equipment-specific financing conversation we've covered in detail in our breakdown of the GMK8700's luffing jib and the bridge-contractor financing case. We've also compared Cat's current telehandler lineup directly in our TH1055 vs. TH1255 sizing guide, which is the more apples-to-apples comparison most telehandler buyers actually need.
Where an Independent Lender Like BFC Fits In
Whether you need a telehandler for daily jobsite work, a crane for a specific heavy-lift project, or both as part of a growing fleet, an independent commercial equipment financing company like BFC doesn't force either decision into a one-size-fits-all box. We finance Caterpillar, Grove, and every other brand on our approved list under one roof, working with startups and existing businesses nationwide across any credit profile. That matters most for a contractor trying to figure out which asset actually belongs on the balance sheet versus which one makes more sense to rent for a single project.
What This Means for a Growing Heavy-Lift or General Contracting Business
A startup or growing contractor often makes the mistake of thinking bigger capacity automatically means more capability, when in practice a telehandler and a heavy-lift crane serve completely different points in a business's growth. Most contracting businesses need a telehandler long before they need to think seriously about owning a crane in the GMK8700's class — and many businesses that do heavy structural work are better served renting that capacity project-by-project rather than carrying it on the balance sheet year-round. Understanding which category your next equipment decision actually falls into is worth more than any spec-sheet comparison between two machines that were never competing for the same job in the first place.
Operator Requirements: Another Place These Machines Split Completely
The gap between these machines shows up just as sharply in who's allowed to run them. Operating a crane in the GMK8700's class typically requires NCCCO certification and extensive, specialized training — this is not a machine a general laborer gets handed the keys to on day one. A telehandler like the TH1255 still requires proper operator training and, depending on the work, OSHA-compliant certification, but the pool of crew members who can be trained up to run one safely is far larger, and the ramp-up time is measured in days rather than years. That operator-availability gap is itself a real-world factor in deciding which machine actually fits your business: a crane sized like the GMK8700 isn't just a capital decision, it's a staffing decision.
Transport and Site Logistics: Also Not Comparable
Moving a GMK8700 between jobs is its own specialized operation, typically requiring permitted oversize transport, careful route planning, and significant setup and teardown time on each site before and after it can lift anything. A TH1255 generally rides on a standard trailer and can be working within minutes of arriving on a jobsite. This logistics gap reinforces the same point the capacity numbers already make: one of these machines is built for occasional, carefully planned deployment, and the other is built to show up and get to work.
What a Rent-vs-Own Decision Actually Looks Like for Each Machine
Because a telehandler gets used nearly every working day on an active jobsite, the rent-vs-own math tends to favor ownership once a contractor's utilization is consistent enough to justify the payment — which is exactly the kind of decision we walk through with TH1255 and similar telehandler buyers. A crane in the GMK8700's weight class is the opposite case for most contractors: unless heavy structural lifts are a recurring, core part of the business, renting that specific capacity project-by-project is usually the more financially sound call, with ownership reserved for crane and rigging companies whose business model is built entirely around that utilization.
What This Means If You're Scaling a Contracting Business
For a growing general contractor or subcontractor, the typical equipment-acquisition sequence runs through telehandler-class material handling well before it ever touches crane-class capacity. A roofing or demolition contractor adding a telehandler is solving an everyday productivity problem — getting materials to height faster, with fewer hands, on every job. A contractor that eventually needs a GMK8700-class crane is almost always either a dedicated crane and rigging company, or a heavy-highway or structural contractor whose project mix has grown to include recurring major lifts. Confusing which stage of growth you're actually in — and buying, or financing, equipment sized for the wrong one — is a far more common and costly mistake than most contractors expect.
A Quick Gut-Check: Which Category Do You Actually Need?
If the job is daily pallet, block, or material handling across a jobsite, you need a telehandler class machine, not a crane
If the job is a single heavy structural pick — a girder, a precast panel, a turbine component — you need crane capacity sized to that specific load, which for most jobs is nowhere near 700 tons
If you're doing both regularly, you likely want to own the telehandler and rent crane capacity project-by-project until heavy-lift volume justifies owning one
If you're not sure which category applies, that's worth a direct conversation before signing any financing paperwork, because the two loans look nothing alike
The Honest Bottom Line
The Grove GMK8700 and the Cat TH1255 both move loads into the air, and that's genuinely where the similarity ends. One is a 700-ton specialized heavy-lift crane; the other is a 12,000-pound daily-use material handler. Neither is "better" than the other, because they were never built to compete — the real decision for most contractors isn't picking between these two machines, it's correctly identifying which category of lift equipment their next job, or their next phase of growth, actually calls for.
