The coil functions as the electromagnetic core of a solenoid valve, relay, or contactor within the electrical control systems of the machine. It converts electrical signals into a magnetic field, which triggers mechanical movement such as shifting a valve plunger or closing electrical contacts. This component is necessary for the precise operation of hydraulic, pneumatic, and electrical circuits throughout the crane.
This specific component is designed for use in the Tadano 300 crane. It is commonly installed in the solenoid valves that regulate hydraulic fluid flow to the boom cylinders, outriggers, or the slewing mechanism to ensure responsive control. When the coil receives the appropriate voltage, it generates the required magnetic force to actuate the valve or relay, allowing the operator to manage complex lifting functions.
In general engineering, a solenoid coil consists of copper wire windings around a core. The electrical resistance and operating voltage must match the specific requirements of the control system to ensure proper activation. A failure in the coil, such as an internal short or an open circuit, will prevent the associated valve or relay from engaging, which can lead to the loss of specific crane functions.
