What is ISO 2057:1981 Agricultural tractors — Remote control hydraulic cylinders for trailed implements?
ISO 2057:1981 specifies the dimensions and performance requirements of remote control hydraulic cylinders for trailed implements used in agricultural tractors. The standard applies to cylinders that are actuated by hydraulic power from the tractor and are used to control the position or movement of the trailed implement.
The purpose of this standard is to ensure compatibility between different brands and models of tractors and trailed implements, and to provide a common basis for design, manufacture, and testing of remote control hydraulic cylinders.
This standard is designed to ensure that remote control hydraulic cylinders for trailed implements used in agricultural tractors are safe, and reliable. And compatible across different brands and models of tractors and implements.
Requirements of ISO 2057:1981:
The requirements of ISO 2057:1981 Agricultural tractors — Remote control hydraulic cylinders for trailed implements are as follows:
Dimensions: The standard specifies the dimensions of the hydraulic cylinder and the mounting details for the cylinder on the tractor and the implement. Thus, The dimensions include the cylinder bore diameter, piston rod diameter, stroke length, and overall length of the cylinder.
Performance: The standard specifies the minimum performance requirements for the hydraulic cylinder. Including its maximum working pressure, maximum load capacity, and minimum stroke length. The maximum working pressure is the highest pressure that the cylinder can operate at safely. While the maximum load capacity is the maximum weight that the cylinder can support.
Hydraulic connections: The standard specifies the hydraulic connections for the cylinder. Including the type of connection, the size of the connection. Also, the maximum working pressure of the connection.
Mounting: The standard specifies the mounting details for the cylinder on the tractor and the implement. Including the type of mounting, the dimensions of the mounting holes, and the torque requirements for the mounting bolts.
Testing: The standard specifies the testing procedures for the hydraulic cylinder to ensure that it meets the performance requirements specified in the standard. So, The testing procedures include pressure testing, load testing, and cycle testing.
Finally, Marking and labelling: The standard specifies the requirements for marking and labelling the hydraulic cylinder. Including the manufacturer’s name, model number, maximum working pressure, and maximum load capacity.
Overall, ISO 2057 is designed to ensure that remote control hydraulic cylinders for trailed implements used in agricultural tractors are safe, and reliable. Also, compatible across different brands and models of tractors and implements.
Benefits of this standard
ISO 2057 specifies the dimensions and interchangeability characteristics of remote control hydraulic cylinders for trailed implements. Which are used in conjunction with agricultural tractors. The benefits of this standard are as follows:
Ensures compatibility and interchangeability: The standard ensures that remote control hydraulic cylinders used for trailed implements are compatible with agricultural tractors and can be easily interchanged.
Facilitates safe and efficient operation: Standardized remote control hydraulic cylinders ensure safe and efficient operation of trailed implements. It helps to reduce the risk of accidents and equipment failure due to incompatible or poorly designed hydraulic cylinders.
Improves equipment performance: The standard helps to improve equipment performance by ensuring that the hydraulic cylinders used for trailed implements are designed and manufactured to the same specifications.
Simplifies maintenance and repair: Standardized hydraulic cylinders are easier to maintain and repair as they use common parts and components, which are readily available in the market.
At last, Reduces costs: Standardization helps to reduce the cost of production by promoting mass production of hydraulic cylinders. It also helps to reduce the cost of maintenance and repair by simplifying the process.
Who needs ISO 2057:1981?
Therefore, ISO 2057 is mainly intended for manufacturers of agricultural tractors, implement manufacturers, and regulatory bodies that are involved in the design, testing, and approval of tractors and their attachments.
Hence, It provides guidance and specifications for remote control hydraulic cylinders used for trailed implements. Which can improve the safety and reliability of these systems. Agricultural engineers, researchers, and technicians working in the agricultural machinery industry may also find this standard useful.
