Double-Girder Overhead Cranes - ORPBA
The double-girder overhead cranes type ORPBA produced by Officine Rovers are designed and manufactured in compliance with the current industry regulations. These cranes consist of box girders connected to end carriages and equipped with motorized wheels, operated by 2 or 4 pendant motor reducers with a three-phase asynchronous motor proportional to the lifting capacity and crane gauge. The motor control is managed through an inverter, allowing precise control of lifting operations.
The lifting group of ORPBA cranes includes a robust ORA-type hoist. This hoist is constructed with a special steel frame on which a winding drum with convergent helical grooves is installed. It is driven by a specially designed parallel shaft reducer and a self-braking three-phase asynchronous motor for lifting service.
The STD (standard) series of ORPBA cranes offers a range of lifting capacities from 2,000 kg up to 30,000 kg. Cranes designed for capacities exceeding 30,000 kg fall under the special series, indicating a customized design based on specific customer needs.
