- Commodity name: Meiheng MHCASC Load Stability Control System - Software V1.0
- Commodity ID: 1323586974954180608
The Meiheng MHCASC Load Stabilization Control System - Software V1.0 is a mature product created by Meiheng's foreign expert team, validated over many years in the field. Its load stabilization control model is designed to be "user-friendly," easy to use and maintain, and does not require regular parameter adjustments to ensure stable operation of the hook (no swinging).
Meiheng's load stabilization controller has a large number of applications abroad, especially in the European market, including typical cases of replacing other brand products.
It is suitable for cranes that require automated or semi-automated control, such as ship unloaders in material yards, warehouse cranes, garbage hoists, metallurgical casting cranes, clamps, and electromagnetic cranes.Usage of Meiheng Load Stabilization Controller
1. The most basic configuration requirements for the crane control system:There must be a PLC control system. (It is recommended to use Meiheng's PLC that is interchangeable with SIEMENS 300 series or other SIEMENS series PLCs. Other mainstream international PLCs can also be used, but prior consultation with Meiheng is required);
The drive for the main and auxiliary mechanisms must be a frequency converter, and it must be connected to the PLC via a communication interface.
2. Additional equipment and software required:
Add Meiheng Load Stabilization Controller: connect to the original system PLC via communication;
Add height detection for the lifting mechanism: an absolute encoder can be used to detect the position of the lifting drum, and the encoder output is input into the original system PLC, which converts it into lifting height value through the PLC program;
Add load height correction switch (16 positions): input 16 position switches into the original system PLC to correct the distance between the load center of gravity and the hook center;
Add to the original PLC software: Meiheng Load Stabilization Controller Software V1.0. Configure the software provided by Meiheng into the original system PLC software program and configure it according to Meiheng's usage requirements.System Architecture
Parameters of Meiheng Load Stabilization Controller
The load swing amplitude is reduced by more than 95% compared to systems without stabilization control measures.
The swing amplitude after automatic positioning stops is <±5mm.
It adapts to load stabilization control for simultaneous (or non-simultaneous) operation of lifting, main, and auxiliary mechanisms, especially suitable for automatic/semi-automatic operation in crane safety areas.Control Method of Meiheng Load Stabilization Controller
Where:
τ = swing period
π = 3.141592654
g = gravitational acceleration (9.81)
l = length of the lifting rope
Therefore, by setting the hook height detection and correction switch, we can obtain the lifting height of the load. Through the model in the software, we can obtain the swing period of the load. During the acceleration and deceleration process of the operating mechanism, the algorithm in the software controls the acceleration and deceleration according to the predicted swing time, thus eliminating the swing of the hook when it stops at the endpoint.
The load weight does not affect the swing period, so if the lifting rope length is the same, the swing period for 1 kg is the same as that for 1000 kg.
The detection of the load lifting height does not need to be very precise; generally, a height correction error of less than 30 cm is sufficient. -
