Liebherr LTM 1750-9.1 load chart summary
What the Liebherr LTM 1750-9.1 can lift at each radius on its main boom, with 204 tonnes of counterweight, outriggers fully extended and 360 degree slewing. Each figure is the highest on the manufacturer load chart at that radius, shown with the main boom length it applies to. The last column gives the load with the boom fully extended to 52m.

Taken from the manufacturer load chart for this configuration and given as a guide only. The hook block and lifting accessories count towards the load, other configurations give different figures, and nothing here forms part of a lift plan: the crane, its configuration and its load chart are confirmed when we quote and plan your lift.
