As businesses continue to grow, some customers are moving beyond the traditional, single-method approach to crane operation. Instead, they are increasingly tailoring their electrical control systems to meet their unique usage patterns and specific requirements—leading to a more diversified range of operational options. Below are the three primary crane operating methods: remote control, operator cab operation, and ground-level control. ) An introduction to it.
1 , Ground Gymnastics
Ground operations adopted 8 + 1 Operation of the button station (waterproof type), where the two lifting mechanisms are controlled by single-speed buttons, each managing the up-and-down movement of its respective mechanism. The trolley mechanism, meanwhile, is operated via dual-speed buttons, allowing separate control of the trolley’s fast and slow speeds—specifically, the first press activates slow-speed operation, while a second press switches to fast-speed control. 1 The knob is the power control. The secondary control circuit uses 36V Safe voltage, via 36V The relay is used to control 380V The contactor. Final execution of the control mechanism's action.
2 , Remote control
Remote control is implemented using 8 The dual-speed button controls are operated via a remote receiver installed inside the electrical control box. The receiver picks up signals transmitted by the remote transmitter, which then activate the mechanism accordingly. This remote control method is favored by many users due to its wide visibility range and convenient operation. However, it still has some drawbacks: for instance, the receiver’s output relay tends to fail easily, and there must be no obstructions within its designated operating range. Additionally, the system requires a dry working environment, free from water, dust, or other contaminants.
Note that the switching between the three operating modes is controlled using a transfer switch.
3 , Driving control
The driving operation is conducted by installing a control panel inside the driver's cabin, with the operation buttons mounted directly on the panel. The button functions are identical to those used in ground-based operations. Additionally, the setup includes features such as an electric bell, lighting, a fan, a start/stop mechanism, a key switch, and indicator lights.
There are many electrical control methods for cranes, and even cranes of the same type may differ in their control approaches due to variations in electrical configuration. The key to design is to maximize the crane's control performance while ensuring that it meets the equipment's process and technical requirements.
