Grove GMK8700 for Bridge and Heavy-Highway Contractors: Financing an 800-Ton Lift

Bridge girder sets and heavy-highway lifts have a way of exposing exactly which crane companies can actually do the work and which ones are one phone call away from subbing it out. The Grove GMK8700 changes that math for contractors bidding DOT and bridge work, and it's worth a look specifically through that lens rather than as a generic "biggest crane Grove sells" story.

The Numbers That Matter for a Girder Set

The GMK8700 is rated at 800 US tons (700 metric tons) of maximum capacity, unveiled at CONEXPO 2026 as Manitowoc's new range-topping all-terrain crane, expanding Grove's all-terrain lineup from 55 to 800 tons. Two boom configurations are available — a 177-ft main boom or a 263-ft main boom — and a luffing jib option extends reach out to 351 ft total. For a bridge crew setting precast girders over an active highway, that reach matters as much as raw capacity: it's often the difference between picking directly from a staging area beside the span and needing a second crane or a more disruptive lane closure just to get the pick within range. Counterweight tops out at 385,000 lbs using Grove's Variable Position Counterweight (VPC) system, which lets the crane trade counterweight positioning for outrigger footprint on a tight highway median or a constrained right-of-way — exactly the kind of site geometry DOT projects hand contractors.

The Carrier and Controls Do the Rest of the Work

An eight-axle carrier with five driven axles gets the GMK8700 across soft shoulders and unfinished grading to a highway pick point without the extra mats and crawler mobilization a comparable-capacity crawler crane would demand — which is exactly the setup advantage all-terrain cranes hold over crawlers on a road project with a compressed lane-closure window. Grove's CCS 2.0 control system and MAXbase 2.0 outrigger positioning let the operator run asymmetric outrigger spreads on a tight median without derating the chart more than necessary, and the crane runs on Grove's MEGATRAK suspension and MegaDrive system for the road transit between sites. Manitowoc builds the GMK8700 at its Wilhelmshaven, Germany facility as the new flagship of a lineup that already includes the Grove GRT765 rough-terrain crane for off-highway lifts and the compact GCD25 carry deck crane for tighter yard work.

Who Should Actually Be Bidding This Crane Into a Job

Bridge and heavy-highway contractors setting precast girders, box culverts, and overhead sign structures on DOT contracts; industrial and power-plant riggers setting cooling towers, boilers, and large tanks where a single super-heavy pick beats a tandem lift; and wind energy contractors who need the reach to set nacelles and hub sections without a specialty crawler mobilization. If your crane needs top out around 300–400 tons, the GRT765 or a smaller GMK model is the more honest fit; the GMK8700 earns its keep specifically on the jobs nothing smaller can pick.

Rent vs. Own at This Capacity Class

An 800-ton crane is one of the most expensive single pieces of equipment a contractor can put on a jobsite, and it's also one of the hardest to rent on short notice — there simply aren't many of these sitting idle in a regional rental yard waiting for your bid window. Contractors who bid heavy-highway and bridge work regularly enough to justify owning one gain something a rental relationship can't offer: the ability to bid the work at all, on your own schedule, instead of hoping a crane happens to be available when the DOT schedule demands it. Every rental invoice for a crane this size is money gone for good; owning one converts that same capital into equity your business keeps building toward the next bridge contract. See our rough-terrain crane buyer's guide for how to think through capacity, boom length, and financing before committing, and our piece on cranes and pavers as overlooked equipment categories for the broader case for owning lift capacity instead of subcontracting it out.

Financing an 800-Ton Crane Through BFC

A crane in this class is a serious capital decision, and BFC structures financing around that reality rather than expecting a contractor to write a check out of working capital. Deposit terms flex with credit profile and deal structure — borrowers with strong, well-established credit can sometimes structure a deal with little to nothing down, while others land in a more moderate range or, depending on the specifics, a larger down payment. Unlike lenders who make you wait years until one machine is fully paid off before touching the next purchase, BFC can help fund the next piece of equipment while this crane is still being paid down — which matters if the GMK8700 is meant to open up a new tier of bridge and heavy-highway bids rather than sit as a single standalone asset.
