What this tool answers
You need to know whether a folding shop crane can lift this engine at the boom length the bay actually needs. The checker adds extras on the hook and compares that working load with a published US 2-ton folding chart. It names a 2-ton class when the selected hole is strictly above the load, and NO_MATCH when it is not. It is not a certified lift plan, a stability calculation, or a substitute for the nameplate on the crane in your shop.
The chart
A common 2-ton folding shop crane (Harbor Freight 58755 and similar Sunex charts) stamps four holes: 2 ton (4,000 lb), 1.5 ton (3,000 lb), 1 ton (2,000 lb), and 1/2 ton (1,000 lb). Capacity falls as the boom extends because the load arm gets longer. This site maps those four ratings to boom settings 1 (shortest) through 4 (longest) so the numbers stay attached to reach, not to a brand’s hole index.
Strictly under the hole
Harbor Freight’s 58755 manual says to locate a hole with a weight limit higher than the weight to be lifted, and gives the example of using the 1-ton hole for a load under one ton. The checker therefore fails an exact 1,000 lb load on the 1,000 lb hole. Use the next shorter, higher-rated hole, or a different crane.
Position numbers are not universal
Harbor Freight 58755 and Sunex 5222 treat Position 1 as the long, low-capacity setting. ATD-10141B does the opposite. Always read the pounds next to the pin. This site’s 1–4 scale is shortest-to-longest on purpose so two brands cannot silently swap meaning.
When the answer is NO_MATCH
If the working load is not under the selected hole, retract the boom if the engine bay still lets the hook center, or stop. If the load is not under 4,000 lb even at the shortest boom, a 2-ton folding class is the wrong tool — do not stretch a cherry picker into a gantry or engine crane it was not built as. This site will not show a purchase button on those results.
VEVOR listing vs this chart
The linked VEVOR folding crane (model SDDJ-0917-11-2T) states four boom positions and a 4,400 lb / 2,000 kg maximum. That is a metric-tonne marketing maximum, not a public per-hole table. This checker keeps the conservative US 2 short-ton class (4,000 / 3,000 / 2,000 / 1,000 lb). Read the decal on the unit you receive. Availability on the merchant page was not independently restock-checked beyond the 2026-09-10 fetch.
Safety notes
Lock casters before pumping. Stay out from under the load. Use a hook with a latch and chain or slings rated above the working load. A load leveler’s own rating can be far below the crane (the VEVOR 2-in-1 kit lists 1,500 lb on the leveler). This site does not certify lifts, floors, or rigging.
