Grove AT865, AT1100: the number after AT marks the tonnage class
On Grove all-terrain cranes, AT stands for "All Terrain", and the number that follows roughly indicates the capacity class in US tons. Factory data puts the AT865's maximum lift capacity at 130,000 lb, just under 59 tonnes, while the AT1100 reaches 220,000 lb, roughly 100 tonnes — the model number sits noticeably above the actual maximum load because it marks the broad market class rather than the exact figure from the load chart.

The "Grove All Terrain Crane" bucket spans smaller classics like the AT400, mid-range models such as the AT422E, AT635E and AT745, up to the large AT865, AT880 and AT1100. Letter suffixes such as E or S generally mark updated variants within a given tonnage class, though the available sources do not support a single, consistent meaning for these letters across every class.
The register's 57 active models span an operating weight of 10,500 to 91,327 kg, engine power from 110 to 447 kW, 6- to 10-cylinder engines, and displacement from 5701 to 16,000 cm³ — a wide technical spread between compact site cranes and heavy-lift machines.
Buying used, what matters most on all-terrain cranes is the condition of the telescopic boom and its slide pads, along with the load-test history. Checking the supplied load chart shows whether the real capacity at a given boom angle still matches the factory figures.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Ask about parts availability for this build year — the running costs hang on it.
