How does a gantry crane work?
Working principle of the gantry crane hoisting mechanism: The basic principle is that the rotation of the motor is transformed into the lifting and lowering movement of the load. When the power is suddenly cut, the brake is applied and the load is stopped at the specified position.
How do gantry cranes move?
A gantry crane is a type of overhead crane with a single or double girder configuration supported by freestanding legs that move on wheels or along a track or rail system.

What is gantry system?
A motion-centric system designed for multi-axis operation with an overhead bridge is regularly called Gantry System. In general, using Gantry System is ideal for dynamic and high duty-cycles processes, which requires high throughput and high precision.
What is gantry operator?
