TOWER CRANES Ӏ BAUMA 2025
Zoomlion’s R800-40
The Potain MR 30
at a 60.6m height, using 11 mast sections plus nine sections of jib.
When anchored to a building, it needs five anchoring frames to reach 210m with a 65m jib (for a C25 wind profile), says Manitowoc. When rigged with three-fall
reeving and a 55m jib, the MR 819’s 64t maximum capacity can be lifted out to 17m radius and up to 10.8t can be lifted at the jib end. With two-fall reeving and a 65m jib, it can lift 42t out to 21m and 7.4t at maximum radius. Supporting these loads is a new hoisting winch: the 270 LVF 213 Optima. With 838m of rope, the high winding capacity of its 200kW motor can produce line speeds ranging from 183m/min in single- fall reeving to 61m/min in three- fall reeving. The 110kW-rated 150 VVF 90 luffing hoist can raise the jib from 15° to 87° in 2min 20sec.

The cab is an Ultra View model with Manitowoc's CCS control system and Potain Connect telematics platform.
SÁEZ Spanish tower crane specialist Grúas Sáez showed its latest flat-top, the 50-tonne TLS 1100 flat-top (which is also available in 20- and 25-tonne versions). “We produced the 50-tonner in response to customer demand,” says Juan Ballester, sales manager at Saez. “At Sáez we want to offer the full spectrum of capacities.” The 1,100-tonne-metre flat-top has an 86m boom and a hook height of up to 71.2m. At a radius of 86m it can lift almost 11t. The crane has two trollies. With
one trolley its capacity is 25t; this increases to 50t with both. It has a 110kW winch with a maximum speed of 114m per minute.
