The difference between rotary hook and chain hoist block

Recently there are some customers inquiry chain hoist block, but is not very clear described by the customer, and after communicating with customer patiently, we understand what customers want is the rotary hook on the manual hoist. About the doubts about the rotating hook and chain hoist block, following by WOKAITE explains the difference of the rotary hook and the manual chain fall for you.
The lever hoist is used for guiding the user to operate the gourd from any angle, so as to avoid the operation standard of the ordinary chain pully block which can not be oblique pulled, and leading to the user work in the dangerous area. The rotary hook relates to the internal design of the lifting hook of an arbitrary rotation angle when lifting heavy objects. For example, in the hoist lifting weights, sometimes the hook opening towards the west, and we tied rope weight is in the direction of east-west, then if the hook can not rotate, and the lifted goods is heavy, it will be very troublesome. The design of rotary hook is to avoid this situation.

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...

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...
