Standard blocks, with from one to six pulleys, can be produced in a short time, with components assembled from stock. Special customised blocks can be designed for producers of overhead cranes, mobile cranes, tower cranes and off-shore cranes. In cases of special needs, one-off products can be created which satisfy even the most unusual requirements. In addition, considerable expertise has been acquired over the years in the construction of motorised and armoured blocks for steelworks.
