Liebherr Ehingen has increased the capacity of its LR 1600/1 crawler crane model by 25% by developing a new heavy boom head.
This has increased the maximum capacity from 600t to 750t and so the crane has been renamed the LR 1750.
The LR 1750 can lift 750t at an 8m radius when rigged with 35m of main boom, 31.5m of derrick mast, 220t of counterweight and 400t of counterweight on the ballast wagon trailing 20m behind.
With the same counterweight and 140m of main boom, it can lift 105t to a radius of 18m, 60t out to 80m and 16.6t at 124m.
