Structure characteristics and application of electric chain blocks

Structure characteristics of electric chain blocks

The body is made of high strength tensile shell or die cast aluminum shell, precision manufacturing by thin wall extrusion, small size, light weight and high strength. Standard electric chain hoist with an independent transmission system, the transmission of the two coaxial transmission gear box, use of long life oil bath lubrication system. Electric chain block hoist powder metallurgy clutch for overload protection device, brake disc using DC electromagnetic field brake, the brake torque is large, stable, rapid and low noise.

Application of electric chain hoist

Mainly used in large factories, warehouses, docks, wind power, logistics, construction and other industries, lifting or handling of goods can also be used for heavy lifting. Electric chain hoist by the operating personnel with button on the ground follow the manipulation can also be manipulated or used in the control room wired (wireless remote control. Electric chain blocks can be suspended and fixed, can be equipped with electric monorail trolley and push / pull monorail trolley traveling.

The tonnage of the ring chain electric hoist: 0.1t ~ 100t.

Electric chain block hoist installation and use.

Single beam hoist, bridge crane, gantry crane, hanging crane can be equipped with single beam and I-beam, can also be equipped with double beam trolley.Therefore, electric chain block is factories, mines, ports, warehouses, freight yard, shops and other one of the common heavy equipment is the necessary machinery to improve labor efficiency and improving working conditions.

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 ...
