Lifting equipment is an important tool for engineering construction and port terminal hoisting. Its large size and high safety requirements are related to the life safety of the operators and the protection of the equipment and the huge property used. Generally, the outdoor environment used by the crane is relatively harsh, so the safe and reliable operation of the automation and monitoring of the crane equipment It seems particularly important.
The crane has lifting, slewing, luffing and running mechanisms. The first three mechanisms are installed on the rotating part and participate in the operation in each cycle. The rotating part is also equipped with a tiltable single boom or a combined boom and a driver's cab. The crane needs precise positioning of the angle during the slewing process to ensure the accuracy of the position of the hoisted items and the safe distance between the cranes. Crane angle acquisition is generally the rotation of the main shaft is converted to the connected pinion through the reduction gear, and the rotation position and the number of turns of the pinion are recorded. At this time, Idico bus type modbus 485 absolute encoder is needed.
This series of products is Modbus-RTU standard communication protocol, single-turn encoder resolution can reach 4096; with zero line and direction line, programming permission line can be set; client configuration tool is supported; small housing size is 38mm. It is economical and reliable, and has been used in batches on equipment such as lifting monitoring and smart construction sites.
