The standard selection of electric chain hoist motor

Electric chain hoist motor is the important part of the whole equipment, WOKAITE have today’s achievement in crane field, can’t be separated from selected materials and exacting standard, the following introduce you electric 1 ton chain motor selection standard.
Ring chain hoist motor with class F insulation. When the elevation and the ambient air temperature is in conformity with the provisions, the motor winding temperature ceiling value of resistance should not exceed, the allowable bearing temperature (temperature) should not be more than the ring chain electric hoist lifting the rated load, when the terminal voltage of the 1 ton chain motor for rated voltage of the agencies can work normally, for conical rotor motor and disc brake motors and residual magnetic pull.
When the three-phase power supply is in balance, the deviation of the average value of three-phase 1 ton chain motor no-load current of any one phase of three-phase should not exceeding three ring chain electric chain hoist motor in reference rated power and rated voltage, locked rotor torque, maximum torque respectively to guarantee the ratio of the rated torque value should not be less than the provisions of the meter.
Locked rotor current provisions should not be greater than the meter to ensure that the ratio of the rated current value; for double speed chain hoist motor, high-speed the assurance value and the provisions of the agreement, extremely low speed to ensure that the value corresponding to the table in the same power to ensure value is allowed to be reduced.

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
