Product Description

Zoomlion crane accessories maneuvering room conversion flameout start emergency stop forced operation switch panel assembly

Function:

The changeover flameout start emergency stop forced switch in the crane operator's cab serves the following important functions:
1. Switching function
Power switching: It is possible to switch between different power modes, such as switching from main power to standby power or switching between different power-using equipment, in order to meet the power requirements of the crane under different working conditions. When the main power supply fails or when specific operation of the crane is required, switching to the standby power supply or other suitable power supply through the changeover switch ensures the normal operation of the crane's electrical system.
Function Selection: Used to switch between different operating modes or functions of the crane. For example, switching between normal operation mode and special operation mode, or switching between different control modes of hoisting, slewing, luffing and other movements, in order to adapt to different hoisting tasks and operation requirements.
2. Engine stop function
Engine stop: it can control the engine off of the crane. When the crane finishes the operation or needs to pause for a period of time, the operator can stop the engine through this switch to save fuel consumption, reduce noise and minimize exhaust emission, and also help to protect the engine.
Safe operation: In some cases, such as emergencies or when the crane needs to be maintained or overhauled, turning off the engine in time is a necessary safety measure. It prevents injury to personnel or damage to equipment caused by accidental operation of the engine.
3. Starting function
Engine start: As an important control component for engine start, the operator can start the crane engine through this switch to provide power for the crane operation. Its design usually takes into account the convenience and reliability of starting to ensure that the engine can start smoothly.
System initialization: While starting the engine, the switch may also trigger the initialization process of the crane's electrical system, so that each electrical device and control system can be restored to its initial state and be ready for subsequent normal operation.
4. Emergency Stop Function
Emergency stop: In the course of crane operation, if an emergency situation suddenly occurs, such as heavy load out of control, mechanism failure, etc., the operator can immediately press the emergency stop switch to stop all the movements of the crane instantly, so as to avoid the occurrence of accidents or to reduce the hazardous degree of the accidents.
Safety guarantee: Emergency stop switch is an important safety protection device, which is independent of other control circuits and operating systems, and can quickly cut off the power source and action actuator of the crane at the critical moment to ensure the safety of personnel and equipment.
5. Forced function
Troubleshooting: When a certain mechanism or system of the crane fails, resulting in the inability to stop its action through normal operation, the forced switch can play a role. The operator can use the forced switch to directly cut off the power supply or control signal of the mechanism to stop its operation so as to carry out troubleshooting and maintenance.
Emergency operation: In some special cases, such as the electrical system out of control, hydraulic system failure, etc., it may be necessary to use the forced switch to take emergency measures to ensure the safety and stability of the crane. For example, when the hydraulic system fails to unload the pressure properly, the forced switch may be used to open a specific unloading valve to release the pressure.
To summarize, the change-over flameout start emergency stop mandatory switch in the crane operator's cab is crucial to the safe and efficient operation of the crane, which not only improves the convenience of operation, but also enhances the adaptability and safety of the crane under various complex working conditions.
