In the crane industry, there are 4 common control methods:
1. Pendent line control
2. Wireless remote control
3. Joystick remote control
4. Cabin control
Below we introduce these four control methods in detail.
1.Pendent line control
This kind of remote control is generally mainly used in a single mechanism of the hoist, generally four main mechanisms for up and down lifting and left and right running. Simple control structure, it is the default configuration of the hoist remote control
Advantages: waterproof and dustproof, protection grade IP65
Disadvantages: simple structure, only suitable for hoist mechanism
2. Wireless remote control
A remote control is a device that uses radio transmission to perform remote operation control or remote control of industrial machinery. It is composed of a handheld or waist-mounted transmitter and a receiving device fixedly installed on the equipment. The operator mouses people's operation instructions into the transmitter through the operation panel of the transmitter, and then the transmitter digitizes the instructions (coding, After encryption, it is transmitted to the remote receiving system in a wireless way, and the receiving system restores the control instructions after decoding and conversion, so as to realize the control of various mechanical equipment.
This remote control is suitable for crane control in most cases. The wireless design makes the operation easier and more convenient. It can receive clear signals within 100 meters.
With receiver total stop indicator
When working, the indicator light is on to make the operation more intuitive
The back of the receiver is equipped with a shock-absorbing rubber pad, which is easy to install and fix and avoid vibration
Advantages: strong operability, convenient operation, high accuracy, sensitivity, signal continuity, anti-interference, remote control distance, waterproof and dustproof, high and low temperature resistance,
Disadvantages: relatively high cost, not suitable for complex institutions
