GP Autolift GP 147 Top Line T8

The GP 147 Top Line T8 hammerhead tower crane represents GP Autolift’s dedication to precision-engineered lifting solutions tailored for complex and large-scale construction projects. Designed by engineer Emanuele Greppi, the GP 147 T8 was crafted to meet stringent European standards EN 13001 and EN 14439, ensuring safety and operational reliability across various job sites.

The crane offers a maximum freestanding hook height (H.U.H.) of up to approximately 48 meters and boasts a modular jib that can extend up to 60 meters. Even at full reach, the GP 147 T8 maintains a tip load capacity of 1.43 tonnes, while offering a significantly higher lifting capacity of up to 7.04 tonnes at shorter radii such as 25 meters. The capacity transitions are smooth and progressive along the jib, with configurations such as 5.50 tonnes at 31 meters, 4.00 tonnes at 40 meters, and 2.09 tonnes at 54 meters.

One of the crane’s hallmark features is its optional Autolift control system, which intelligently optimizes performance and safety. When Autolift is not in use, intermediate loads are reduced by 10%, making the inclusion of this system a strong recommendation for maintaining efficiency and safe handling under varying loads. The system uses a current sensor for automated speed regulation, which helps prevent overload and maintain smooth lifting motions even under challenging conditions.

Mechanically, the crane is driven by dual rope winches with a standard winch power configuration of 2 x 4.0 kW motors for primary lifting, and 2 x 3.0 kW for trolley movement. The main lifting speed can reach 19 meters per minute depending on the load and rope layer, providing balanced speed and control. The lifting rope is a φ12mm LEBUS type, with a maximum available rope length of up to 670 meters on higher-capacity winch configurations.

The turntable base dimensions are 4.5 x 4.5 meters, giving it a stable footprint for high-reach operations. This stability is crucial when paired with the long jib and significant payloads, ensuring safety during dynamic lifts.

The GP 147 T8 is engineered not just for strength, but for intelligence, adaptability, and operator convenience. It’s well-suited for urban construction, high-rise development, and infrastructure projects where high hook heights and long outreach are essential. With precise load chart data and modern lifting automation, it stands as a premium solution for contractors needing efficiency without compromising safety or reach.
