Analysis of the relationship between the components of electric hoist

The use rate of electric chain block hoist in china is very high, there are a lot of people do not understand how it works, WOKAITE tell you the relationship between the components of electric hoist. First of all, in the process of production, the electric hoist can participate in the specific process operation, its basic structure is similar to that of the ordinary overhead electric hoist, but it also has a special working mechanism or device on the electric hoist. This kind of electric hoist is characterized by frequent use, bad condition and high working level. Four truss type structure is composed of four pieces of plane truss combined into a closed space structure, generally install the platen in the upper horizontal truss surface, light weight, high stiffness, manufacturing is complex and has less production. Truss structure is similar to bias rail box girder, composed of four pieces of steel plate to form a closed structure, in addition to the main web is a external beam, the remaining three steel plates cut into many windows according to design requirements, electric hoist capacity up to five hundred tons, up to 60 meters span. The structure of simple beam overhead EOT crane electric hoist is similar to that of ordinary overhead electric hoist. The main beam and the end beam are rigidly connected, with wheels at both ends, used to support electric hoist run on overhead beam. In the box structure can be divided into the normal box double beam, the deflection of the box girder, the deflection of the box girder, such as a single beam.

WOKAITE is a professional manufacturer and of 5 ton electric chain hoist,high quality and reasonable price,serve for B2B customers,looking forward to get your inquiry.

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 additional load

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 sale
