Overload protection: This can be achieved through a variety of mechanical mechanisms, such as load cells or pressure sensors, that detect when the load being lifted exceeds the maximum rated capacity of the crane. Once the overload is detected, the system can automatically shut down the crane or limit the crane's lifting capacity to prevent further overloading.

Overheating protection for lifting motor: This protection system monitors the temperature of the lifting motor and can automatically shut down the motor if it reaches a certain temperature threshold to prevent damage or failure.

Overcurrent protection for lifting motor: This protection system monitors the current flowing through the lifting motor and can automatically shut down the motor if it exceeds a certain current threshold to prevent damage or failure.

Motor insulation protection: This protection system monitors the insulation of the lifting motor and can automatically shut down the motor if the insulation is damaged or deteriorating, which could lead to electrical shock or other hazards.

Limit switches: These switches are used to prevent the crane from traveling beyond its designated working area or to prevent the trolley from traveling beyond the edges of the runway.

Rope slacking protection: This system monitors the tension in the lifting ropes and can automatically shut down the crane if the ropes become slack, which could cause the load to fall or the crane to tip over.

Declining lifting protection: This system can detect if the load is declining or if the crane is becoming unstable, and can automatically shut down the crane to prevent accidents.

Alarm horn and flash lights: These safety features can alert workers and others in the area if there is an emergency or danger present.

Safety latch for hook: This latch ensures that the load is securely attached to the crane and prevents it from accidentally falling off the hook.

Bridge gear motor locker and single girder trolley locker: These features lock the bridge and trolley gears to prevent unintended movement of the crane.

Low voltage protection: This system can automatically shut down the crane if the voltage drops below a certain threshold, which could cause the crane to malfunction or fail.
