Single girder overhead cranes are typically made up of several key components, each performing a specific function to ensure safe and efficient operation of the crane. Here is a breakdown of the main components:
| Component | Description |
|---|---|
Main Beam (Girder) |
The main structural part of the crane, typically a box-shaped steel beam. It bears and transmits the weight of the lifted load. The length and height of the beam depend on the crane's usage requirements and site conditions. |

|
1. Mainly bears translational transportation: the end beam is the key component for bearing translational transportation. 2. Connecting the main beam and wheels: The end beam is connected to the main beam, which is where there are four wheels at both ends of the crane beam. There are two wheels on one side, one driving wheel and one driven wheel. Each end beam is equipped with a motor to bear the translation of the crane. |
| Electric hoist
|
The core component of the crane, including electric hoists, winches or manual hoists used to lift loads. Usually driven by an electric or manual drive system. It consists of a frame, motor, gearbox and brake, which enables the crane to move horizontally on the main beam to complete the lifting task. |
| Control System
|
The critical part of the crane that includes the electrical control box, control buttons, remote controllers, etc., used to control the crane's movements. The control system typically includes safety features such as overload protection and limit switches to ensure safe operation. |
Electrical System |
Includes the power cables, motors, inverters, etc., providing power and control signals to the crane. The quality and stability of the electrical system significantly impact the crane's performance and safety. |
| Auxiliary Equipment | Additional equipment like counterweights, limit switches, and safety protection devices that ensure the stability and safety of the crane during operation. |
Different types of single-beam cranes may have slight variations, but the components listed above are typical for most single-beam crane configurations.
