Automatic control of crane

With the continuous improvement of the level of production automation, Single girder eot crane can make full use of space, has been used as a carrying robot, and become one of the key equipment of material handling automation. The update and development of single girder overhead cranes, depends on the improvement of automatic control and electric drive. Experts estimate that 20% ~ 30% of the bridge crane need to install automation system in the future.

For the single girder overhead cranes with automatic grab goods function, in order to accurately handling the goods, improve production efficiency and prevent spreader motion can not effectively positioning, should generally be selected anti shake function of the spreader. Sling anti swing with mechanical type, hydraulic type, electronic type and rigid guide rod type and other types, somecountries have developed a kind of fuzzy logic control technology to achieve the best anti swing control.

In some special occasions, such as the lifting of nuclear fuel, the installation of precision parts, require industial EOT crane to be able to positioning precisely. When choosing this kind of single girder overhead cranes, the positioning accuracy should be put forward. According to the needs, can install computer in the cab and the screen automatic display coordinates, automatic process control the handling of various operations. For some important applications of single girder eot cranes, in order to ensure the safe use of the crane, optional install running state and fault self diagnosis and monitoring system. The system can automatic display of most of the routine maintenance inspection contents, such as the load of the single girder overhead crane, force and vibration, the working condition of the major electrical components, temperature rise of the motor, brake lining wear, wire rope, drum and pulley working condition.

How to deal with 3 ton electric chain hoist motor overheating

Any machine has the cycle and time of operation, is not suitable for a long time continuous operation. Long time operation will cause mechanical damage and even accidents, but in general if the 3 ton electric chain hoist surface temperature is too high, we need to check what is the reason. Firstly to check whether it is because the electric hoist weight is too large, beyond the 3 ton electric chain hoist rated weight. Overweight operation will make the motor over heating, overload for a long time will cause irreparable damage to the electric chain hoists for sale.  Electric hoist motor  is not overloaded, but still heating, should check whether the motor bearing damaged; Should also check whether the motor Work according to regulations, which is one of the reasons causing the motor heating. When the electric hoist motor is running, brake clearance is too small, not completely disengaged, causing great friction, while the frictional heating is also equivalent to the additi...

The reason of electrical wire rope hoist does not work after starting

Mainly because of the hoist does not reach to the rated operating voltage, there are generally 3 kinds of situations: 1.Find out whether the power supply system supply power to wire rope electric hoist , generally used test pencil, such as no power supply; 2.The main control circuit of the wire rope electric hoist is damaged, the line is broken or the contact is bad, can also let the hoist motor not be electrified. This situation, need to overhaul the main control circuit. When maintenance, in order to prevent missing phase to burn the motor casused by the main control circuit supply power to three-phase motor, or hoist motor suddenly operate and cause danger, must disconnect electrical wire rope hoist motor from the power supply, only supply power to the main control circuit. Then start and stop switch, check and analyze the working condition of the electric appliance and the line, repair or replace the failed electric appliance or line. When the main control circuit is confirmed...

Working level of overhead gantry crane

Overhead gantry crane  installation site and the work conditions is vary greatly, the use of lifting capacity and working frequency are also different. In order to use the crane economically and reasonably, it is necessary to choose the appropriate working level according to the working condition of the crane. The working level of the bridge crane is divided into A1 ~ A8, according to the level of the crane and the load state, that is, according to the frequency and load degree of the crane through the calculation to determine. The crane has a certain number of working cycles during its useful life. A working cycle of a  travelling gantry crane  is to start the process of loading the goods from the beginning to the next. The total number of working cycles represent the utilization of cranes. In order to facilitate the calculation, the total number of working cycles can be divided into 10 categories. 200-400 ton heavy duty travelling  overhead gantry crane for ...
