Safety operation rules of electric hoist chain

In the process of electric hoist maintenance, we found some customers are not operating correctly in the using process, in order to make customers operate electric hoist correctly, following by WOKAITE to share how to use electric chain hoist safely:
1.Do not operate the electric hoist in explosive gas environment.
2.Stable and accurate button operation is required, do not operate button intermittently and fast.
3.Try to avoid excessive point operation.
4.Make sure that the motor is completely stopped before doing the reverse movement.
5.After chain electric hoist operation is completed, please let the controller cable and the hook in vertical static state, not swing or sliding.
6.When lifting, the load must be on average and close to the center in order to ensure the balance, do not lift the weight imbalance.
7.Do not use the electric chain block hoist to do the action of dragging the weight laterally.
8.Please do not lift while using the hook to hook the chain which blind with heavy objeacts.
9.Do not stand under the heavy objects when lifting.
10.When lifting operation, the operator must face to and pay attention to lifting weights.
11.The overweight lifting is risky and should not be attempted.
12.Don’t lift when the chain is tangled.

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...
