Gantry Crane (gantry crane)

Structural Components:
Metal Structure: Primarily composed of the main beam, outriggers, and lower crossbeam, forming the gantry frame and providing support and load-bearing capacity for the crane.
Mechanical Transmission System: Includes the hoisting mechanism, trolley mechanism, and trolley mechanism.
Electrical Control System: Controls various operations, including starting, stopping, and speed regulation, to ensure accurate and safe operation.
Operating Principle:
The hoisting mechanism uses an electric motor to drive a reducer, which, through a gear transmission, drives a reel. The wire rope controls the hook's rise and fall, achieving vertical transport of cargo. The trolley and trolley mechanisms are each driven by an electric motor, moving the gantry crane longitudinally along the ground track and the trolley transversely along the main beam track, transporting cargo to the designated location.
Classification:
- By Main Girder Type: Gantry cranes can be divided into single-girder and double-girder cranes. Single-girder cranes have a simple structure and are suitable for smaller loads, double-girder cranes have a higher load capacity and are used for larger loads.
- By Outrigger Type: Gantry cranes can be divided into L-type and C-type outriggers. The L-type is easy to manufacture and install, while the C-type reduces interference between cargo and outriggers.
- Based on support method: They can be divided into rail-type and tire-type. The rail-type is stable and adaptable, but requires track installation, the tire-type is flexible and unrestricted by site conditions, but is slower.
