As its name implies, the "overhead crane" is a car that walks in the air. The crown block is also called travelling crane or crane, which all refer to hoists in the workshop.

[Features]

The characteristic lies in that the transport track is on both sides of the top of the workshop. The main part is the main girder across the tracks on both sides and the hook for suspending heavy objects. Therefore, the corresponding crown block wireless remote controller is also called travelling crane wireless remote controller and crane wireless remote controller; Industrial remote controller, wireless remote controller and industrial wireless remote control are the common names of remote controller in industry.

Wireless means there is no line connection for transmission. The crown block wireless remote controller transmits signals in the form of radio waves. The crown block wireless remote controller is composed of the transmitter part and the receiver part of the wireless remote controller of the crown block. The telecommunication distance of crown block wireless remote controller is usually 100 meters, and the characteristic of radio wave transmission is that the wavelength is longer, and obstacles basically have little effect on it. As long as there is a little gap, it can bypass obstacles, ensuring the effectiveness of its communication. Just like the principle of radio wireless signal transmission, the signal transmission is not influenced by environment, no matter in an open environment or a closed environment.

[Application]

The crown block wireless remote controller is mostly being used in single-girder and is basically popular for single-speed crown block, and the remote controller for single-girder and double-speed crown block, double-girder and single-speed crown block and double-girder double-speed crown block (travelling crane or crane) at present.

[Advantages]

The usage of crown block wireless remote controller mainly brings convenience for workers, ensuring their safety and improving work efficiency. As far as the cost of the enterprise is concerned, it can save the cost of frequent replacement of the original control cable handle and the labor fees and trouble caused by it. The investment in driver for those crown block needed to be operated by people can be saved by improvement of remote controller! At present, the remote controlling modification of crown block is becoming increasingly popular due to saving manpower, convenience to use, improved life safety factor and distance from dangerous environments.
