680723-2

680723-2 is a type of industrial standards for cranes, pendant controllers, and associated apparatus. This standard converts the electrical signals generated by the controller to the physical output movement of the crane or other similar apparatus. While the safety and reliability of this type of apparatus is mainly determined by the manufacture, the standard 680723-2 is an important factor to ensure that the equipment works as desired.

The 680723-2 application field covers all kinds of crane types, including mobile, bridge, gantry, and electric overhead cranes, as well as portal and railway cranes for indoor or outdoor applications. It applies to a variety of crane types which include all types of hoists and lifting devices, monorail systems, spreader beams, and personnel carriers.

The selection of the 680723-2 standard for the application defines the necessary technical requirements that must be considered and met. Specifically, the standard covers details of the following sections:

• Pendant controls: This involves the operator\'s cab, control columns, control panels, switching functions, display systems, emergency stop systems, brakes, and limit switch systems used to control the motion of the crane or other related apparatus.
• Motor control: This involves the equipment necessary to control the motor speed and torque of the crane or other related apparatus.
• Safety equipment: This involves protective devices to ensure the safety of people and equipment, such as overload protection systems, personnel carrier protection systems, and interlock controls.
• Peripheral equipment: This involves ancillary equipment used to operate the crane or other related apparatus, such as radio communications, signal systems, and visual displays.
• Safety regulations: This involves regulations concerning the inspection and control of the crane or other related apparatus, such as procedures for maintenance and testing, and inspection and certification.

The 680723-2 standard consists of a set of requirements that must be met in order to meet the application of the standard. The requirements are divided into four categories:

• General requirements: This covers the scope of the standard, definitions of the components, the type of electrical equipment to be used, and safety requirements to ensure that the equipment meets the highest safety standards.
• Design requirements: This covers the requirements for the design of control systems, motor control systems, and safety systems, including the requirements for the installation and tests.
• Testing requirements: This covers the requirements for the testing of products, components, and materials used in the production of crane and other related apparatus.
• Maximizing safety: This covers requirements to maximize the safety of equipment, such as requirements for the use of protective devices and protective measures.

The working principle of the 680723-2 standard is based on the process of converting electrical signals to physical output movement. The electrical signals generated by the controller are sent to the load, such as a motor or a servo motor, and the load is used to generate the desired movement. The signal is also sent to the actuator, which is used to control and limit the motion of the crane or other related apparatus. The output of the actuator is then used to control the crane or other related apparatus.

In addition to the electrical signals, the 680723-2 standard also defines the safety requirements necessary for safe operation of the crane or other related apparatus. In general, safety measures are required to ensure that the equipment is able to stop in a predictable manner, thus preventing unexpected accidents.

The 680723-2 application field and working principle is an important standard which ensures that the crane or other related apparatus is safe and reliable. The main features of the standard are the comprehensive requirements which must be satisfied in order to ensure the highest safety and reliability. The working principle of the standard is to convert the electrical signals generated by the controller to the physical output motion required for the crane or other related apparatus.
