In case of overloading, the sound-light alarm of the load indicator will be triggered and signals will be sent out. Together with the Peripheral Control Circuit of the crane, it stops the crane from moving towards dangerous directions (for instance, lifting the hook). Operators should first and foremost reduce the weight or move the crane towards safety directions (for instance, lower down the hook) until the alarm stops. Then, proceed to further operations of the crane. | A2B switch
The switch is installed with a weight of appropriate weight, and the up and down movement of the hook is used to lift or release the weight. When the weight is disconnected or the switch is turned on, the power supply brake system of the winch is automatically cut off to limit the overwinding of the wire rope and to achieve the purpose of lifting the hook within a certain height. | ZX load cell
The ZX axle pin weight sensor is installed at the axle pin of the fixed pulley on the lifting rope, replacing the original axle pin installation position. The fixed pulley is close to the axle pin sensor. When the fixed pulley is stressed, the part close to the sensor will generate force, causing the sensor to deform, thereby outputting the corresponding modulus value to detect the stress condition. It is suitable for lifting equipment with rigging, connecting forks, lifting rings, etc. |
Wireless transmission module and angle sensor | Angle sensor
JD-180 crane angle sensor consists of a potentiometer and a pendulum, which can be installed on the boom of the crane. The angle of the boom to the ground is measured by the weight driving the potentiometer to rotate and output the corresponding voltage value.
This angle sensor has the characteristics of stable performance, high reliability and simple installation. |
