Safety protection for a double girder overhead crane should not be treated as a simple checklist. The required configuration needs to match the actual operating conditions, load characteristics, working environment, and risk scenarios of each project.

Common protection functions may include overload protection, power-loss protection, travel and lifting limit switches, emergency stop systems, overheating protection, and anti-collision devices. However, the specific requirements and configuration can vary significantly between different crane projects.

For this reason, safety functions should be clearly defined in the technical agreement before production. Buyers and suppliers should confirm which protection devices are included, their operating logic, and any additional requirements for the actual application.

The video below explains why a clearly specified safety configuration is an important part of selecting and purchasing a double girder overhead crane.
