Overview
The compact modular design ensures optimal hook approach, adhering to FEM/DIN/ISO standards.
Operational efficiency is enhanced by eliminating counterweights. All variants up to 15t , come with a standard supply of Duty Class ISO M5/FEM 2m. The flange width is easily adjustable through threaded screws and fasteners. Standard inclusion of frequency inverters in both lifting and cross-travel movements ensures increased longevity of mechanical components. Speed control via inverters allows for selectable speeds, providing precise handling and smooth movement.
