Wolffkran Wolff 7534.8 clear

The WOLFF 7534.8 clear is the largest and most powerful flat-top crane in the WOLFF clear series, designed specifically for demanding inner-city construction sites where space, speed of assembly, and efficient operation are paramount. As the flagship of WOLFFKRAN’s 315 mt class flat-top lineup, the 7534.8 clear boasts a maximum load capacity of 8.5 tons in double-reeved configuration, with a tip load capacity of 3.4 tons at a 75-meter radius.

Its seven-section trolley jib extends from 30 meters up to 75 meters in 2.5-meter increments, enabling flexible site configurations. The crane uses high-performance hoisting winches—either the 45 kW Hw 845 FU or the more powerful 75 kW Hw 875 FU—allowing partial load working speeds up to 185 m/min and hook paths up to 460 meters in 2-fall operation. An automatic power reduction feature ensures optimal performance even under weak mains supply conditions.

Assembly and transport are designed for maximum efficiency. The compact cab station attaches with just two bolts and can be transported as a single unit. The crane’s flat-top design, with no tower top section, means the jib can be assembled entirely in the air—ideal for sites with limited ground space or smaller mobile cranes. Additionally, components are optimized for container transport, and the counterjib folds or separates easily to fit on standard trucks.

Operator comfort and safety are central to the 7534.8 clear. The spacious WOLFF Cab offers wide visibility, ergonomic controls, air conditioning, modern technology including Bluetooth hands-free, USB/SD ports, and a touchscreen PC. The hoist drive with WOLFFKRAN’s frequency converter allows precise load positioning and smooth handling.

Standard safety and control features include WOLFFBoost electronic overload protection, slack rope monitoring, anti-collision interface, working range limitation, electronic load measurement, and the WOLFFLink data transfer system. The tower system uses WOLFF’s proven bolt connections, and optional climbing devices allow external or internal climbing as required.

Overall, the WOLFF 7534.8 clear delivers exceptional lifting performance, smooth operation, high-end safety, and efficient assembly—all essential qualities for modern high-rise and confined-site projects.
