Classification of industrial handles and typical applications
Industrial handles, as an integral part of the control system of construction machinery and an indispensable part of the human-machine interface, are now widely used in many fields and branches such as handles of domestic construction machinery, agricultural machinery, and aerial work platforms.
In current industrial use, according to the major classification of control forms, there are roughly three types of industrial handles:
1. Mechanical handle; 2. Hydraulic handle; 3. Electric control handle.
Among them, in most industries, mechanical handles have been gradually eliminated in the process of industrial upgrading in my country due to their inability to complete complex analog actions and logic control, and are only used in some low-cost occasions with high cost requirements.
The hydraulic handle, or the industry collectively referred to as the hydraulic pilot handle, is currently the mainstream application in the market. Its advantage is that it can use a lower cost to control the flow of the hydraulic pilot valve and cooperate with the controller to perform basic logic control. In addition, the pilot Because the handle is not involved in electrical performance and other faults, its maintenance and replacement are also more convenient, but there are also occasions where hydraulic handles cannot avoid oil leakage, and cannot be used in some occasions with higher operating environment requirements.
Finally, there is the electronic control handle, which has stable electrical signal, strong editability, and can handle complex operation logic. The tendency of the system to switch to an electronically controlled system. The advantage of the electronic control system is that it can do more complex logic systems and safety systems, and it has been used for decades in the aerial work vehicle industry with high safety factor requirements. And the electronic control handle system can be used in many industries that require high environmental cleanliness, such as supermarket storage, video surveillance, medical treatment, etc.
