Overhead cranes are widely used in companies that need to move large parts inside their warehouses. Synchrony and assertiveness in the movement direction are extremely relevant factors for this kind of component transport. Without these factors the large parts could fall, consequently, causing accidents and financial losses. Often, depending on the size of the object, it is necessary to use more than one associated bridge crane to succeed in moving the materials.

A Brazilian aviation company uses two parallel bridge cranes to carry parts of aircraft, such as wings. To ensure that there are no problems between the two bridge cranes a system was required to prevent asynchrony since even a simple power failure could interfere with the system's operation. A NOVUS solution was developed with a provider partnership for customer safety. Consisting in a PLC - Programmable Logic Controller - monitoring the variable-frequency drives and an AirGate Modbus communicating between the two bridge cranes. The application can immediately send a command that interrupts the operation of the two bridges when there is a difference of direction or speed between them. The NOVUS gateway was chosen mainly for two reasons. The first one its wireless communication, so that it wouldn’t interfere in the mobility of the bridges. The second one is the reliability in the communication link, essential to identify any failure instantly. This solution guarantees the safety of the items transported and prevents accidents.

Economy: with AirGate Modbus communication system you save time.
Safety: for accident prevention and material loss.
Link Reliability: secure communication between the two overhead cranes.
