Grove's TMS500-2: Manitowoc's Return to the 40-Ton Truck Crane Market After a 12-Year Absence

For about twelve years, Grove was out of the conventional truck crane market in North America, having shifted its boom-truck-class offerings toward the National Crane brand it also owns. The TMS500-2 marks Grove's return to building a true truck-mounted crane under its own name -- a 40-ton-capacity machine mounted on a purpose-built carrier rather than a repurposed commercial truck chassis, and the comeback is worth understanding both for what it says about the market and for what the machine itself actually offers.

Real Specs on the TMS500-2

• Maximum capacity: 40 US tons (36.3 tonnes)

• Main boom options: 29-95 ft or 32-102 ft, four-section full-power boom

• Offsettable telescopic swingaway jib: 26-45 ft

• Maximum tip height: 128.2 ft (on the 95 ft boom configuration)

• Total gross vehicle weight: 55,944 lbs

Why a Dedicated Truck Crane Carrier Still Matters

The practical distinction between a true truck crane and a boom truck built on a commercial chassis comes down to the carrier. A purpose-built truck crane carrier is engineered from the ground up around outrigger placement, counterweight, and crane-specific load paths, rather than having crane capability added onto a chassis designed first as a highway truck. That generally means a cleaner load chart and more predictable rigging behavior at the carrier's rated capacity, which is exactly the kind of machine a crane rental fleet or a rigging contractor wants when the job calls for genuine truck-crane capacity rather than a boom truck pressed into crane duty.

Why Grove Stepped Back In

Grove's twelve-year gap in this specific class tracked a broader industry shift toward all-terrain and larger boom-truck-class machines for a lot of the work that used to go to conventional truck cranes. The TMS500-2's return signals Manitowoc sees renewed demand for a dedicated 40-ton-class truck crane distinct from both its National Crane boom trucks and its larger GMK all-terrain line -- likely driven by rental fleets and contractors who want true truck-crane rigging characteristics at a capacity point that doesn't require the cost or complexity of an all-terrain machine.

Financing a Machine Re-Entering the Market

A model returning to a market after a long absence is worth a slightly different conversation than financing a well-established, continuously updated line, mainly around resale expectations. Because the TMS500-2 doesn't have twelve years of continuous used-market comparables behind it the way an uninterrupted product line would, we lean on current new-equipment data and Grove's broader truck-crane and all-terrain resale history when structuring terms, rather than pointing to a deep used-TMS-series comparable set that doesn't fully exist yet. That's a normal part of financing any genuinely new or returning model, not a reason to avoid it -- just a reason to have the conversation directly rather than assume the numbers work exactly like an established product.

Who This Actually Fits

Crane rental fleets rounding out their capacity range between boom trucks and all-terrain cranes, and rigging contractors who specifically need genuine truck-crane load characteristics at the 40-ton class, are the realistic buyers here. If your fleet already runs a comparable National Crane boom truck or a Grove GMK all-terrain crane covering this capacity range, the TMS500-2 is worth evaluating specifically for jobs where a boom truck's chassis-sharing compromises or an all-terrain crane's extra cost and complexity don't fit the work.
