The remote operation of the crane is simple and has hidden safety hazards, which increases the failure rate of the whole machine. Therefore, some customers will switch to wired remote control operations. The correct use of the remote control for cranes can reduce equipment failures and potential safety hazards.
Should the crane be operated by a cable remote control or a wireless remote control? Before long-distance control of cranes was widespread, small-tonnage cranes were operated by remote controls, while large-tonnage cranes were basically operated by the driver's cab. The remote control is actually a set of switches. In order to facilitate the operation of the crane, the designer leads the switch of the electrical control system through the remote control cable, and leads it from the bridge position of the crane to the remote control on the ground. The operator can control the corresponding actions of the crane through the micro remote control.
Because of the cable tying, the operator inevitably needs to pull the remote control wire when using the bridge crane. Therefore, the remote control rope generally has one or two steel wires, and the effect of the steel wire is to accept the pulling force. However, in actual application, many users did not notice the effect of the steel wire, and the loose steel wire cannot be bundled with a special wire buckle in time. In this case, if you continue to use it, the remote control wire will be disconnected, causing the crane to malfunction.
Violent operation of the remote control is also a common problem. The remote control is basically made of insulating plastic materials. If the operator does not pay attention to the protection, it is very easy to damage the shell. For example, after using a bridge crane, the operator releases the remote control away from the hook. Because of the inertial effect, the remote control often collides with the hook severely. After repeated many times, the remote control is completely different. Especially once the emergency stop button of the remote control fails, it is very dangerous in an emergency.
Regarding the use of the remote control, the unit using the crane should pay attention to its daily operation and management. Once a problem occurs, it must be dealt with in time, and the crane must not operate with illness.
Although the crane remote control is easy to use, many users are particularly worried that it will not work due to malfunction. In order to avoid or reduce the impact of the crane remote control, what should we do?
1. If the crane remote control has not been used for a long time, please reinstall the battery before reusing the battery and continue working after receiving the indication signal.
2. The user should remember how to deal with emergencies.
3. The transmitter should be placed as far away as possible to avoid accidental contact. If you use it for more than 8 hours a day, you should store the crane remote control battery for 15 days to check the power supply once to ensure normal use.
4. If the lifting fails during the lifting process, check whether the power supply or fuse of the remote control of the crane is normal. It should be restarted after each check and then re-enabled.
Mastering the above four points can well protect the remote control of the crane. If this is a simple jumper crane remote control, just disassemble the original remote control, and then set the new remote control according to the internal coding dial, and the remote control will work.
Modern remote controls are mainly composed of integrated circuit boards and buttons. These buttons are defined by messages used to generate different messages. The main component of the transmitter part of the remote control is the infrared light-emitting diode. Because its internal material is different from ordinary light-emitting diodes, when a certain voltage is applied to its two ends, the driving wireless remote control will emit infrared light instead of visible light.
