Main characteristics of wire rope electric hoist

Electric hoist with compact structure, electric hoist which motor axis is perpendicular to the drum axis adopts a worm gear transmission device. The disadvantage of large length and width, heavy mechanical structure, low efficiency, difficult processing. The hydraulic system is a double control, the overflow control valve and the magnetic contact pressure gauge can control the pressure accurately. Electrical control department adopts low voltage control, increase the safety of the control system, theree is no factory to produce this kind of structure type of products.
Structure and features: the machine adopts the mechanical and electrical integration design, you can press different specifications of the steel wire rope by changing different mold, simple and safe control. The hoist motor is parallel to the drum axis, and the electric wire rope hoist has the advantages of small height and length. The disadvantages are large size, poor grouping, complex manufacturing and assembly.
Wire rope electric hoist is composed of: hoist motor, transmission mechanism, drum and sprocket, can be divided into four different types according to the position of motor and drum. The pressing wire rope is big tension, beautiful and quick, and the pressing of a wire rope can be completed in a few minutes, which greatly reduces the labor intensity and improves the working efficiency.
The electric hoist which motor is installed on the outside of the drum, has the advantages of good grouping performance, high universality degree, easy change of lifting height, convenient installation and inspection.
Electric hoist is widely used, but the operating personnel who can correctly use of electric hoist advantages may be less, we suggest you to know more about electric hoist motor specifications to use it better.

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...

Cause analysis of the damage of electric hoist rope

Electric drum occurs  electric chain block hoist  rope breaking phenomenon after the replacement of the drum for a short time, although the rope guide device is vulnerable parts, but in addition, there is an unexplained collapse. Rope guide specifications: unless calibration, can generally be divided into for cast steel and for cast iron, the steel drum rope guide for the lifting height above 12 meters with smaller diameter, cast iron drum rope guide for lifting height below 12 meters with large diameter. After the replacement of the drum of the  electric wire rope hoist  is not the original component, it may lead to the uneven force of the guide rope, and may be because of the installation procedure or the components do not match.  WOKAITE  recommends you, if parts damaged, must try to contact the buyer at the time of the original components. The maintenance of explosion proof hoist should be carried out in accordance with GB3836.13, the danger zone r...

Overhead gantry crane lifting instructions

The overhead crane in workshop should not use mechanical lifting, because the top of the rail is close to the bottom chord of roof truss, in addition, the volume and weight of the heavy duty gantry crane are large. Small and medium sized overhead travelling gantry crane used single mast upright integral hoisting, which can improve work efficiency, shorten the construction period, reduce high-altitude operations, the construction procedures are as follows. Erecting mast 1.The height of the mast The maximum height of the mast is the height from the ground to the roof, minus the operating space between the top of the mast to the roof panel and the height of the sleeper. Minimum height should meet the needs of lifting height. 2.Mast position Since the mast is to be erected at the center of gravity of the travelling gantry crane between the two main girders of the trolley, the trolley must be biased, and the mast should also deviate from the centre line of the plant. The deviatio...
