The electric wire rope hoist case we share you today is a very representative customized solution. These 2 units electric hoists are fixed on a frame, they work together, raised and lowered synchronously, just like looking a mirror.
In June 2022, the Vietnam customer contacted us to inquire electric wire rope hoist products. Since the lifting capacity required by the customer is 32 tons and with 12 meters lifting height, we recommend the QDX model trolley. Customer told us his special working conditions; he only needed a hoist which couldn't move, just fixed on a frame.
Detailed working conditions of Vietnam customer

Vietnam customer showed us his drawings which are a good illustration of his specific working conditions and the hoist usage. According to the drawings, we need to install two electric hoists on both sides of the frame to lift the mold (oven cover) in the middle blue part. The mold needs to be raised and lowered at the same time, and does not need to run left and right.
In addition, the custom-made movable pulley block also replaces the traditional hoist hook block, and the movable pulley block has a fixed base for fixed connection with the mold. The pully arrangement of the pulley block is shown in the figure below:

At the same time, we provided the customer with two schemes, one is 32t and the other is 20t. After comparing the schemes, the customer finally decided to choose the 20 ton electric hoist solution, which can meet the needs of use.
Customers are more rigorous in communication, and they will repeatedly ask for confirmation on the issues they want to confirm. Such as product type, model, brake type, frequency conversion, product configuration and so on.
Among the questions asked by customers, the most important one is frequency conversion. The mold cover of the customer has the large tonnage and high value feature. It is necessary to reduce the impact on the mold during the lifting and lowering process. The more stable the better. Therefore, we equipped the two electric hoists with frequency converters to make the whole lifting process very smooth and stable.
The lifting and lowering button have two key strokes, slow speed and fast speed. Lightly press for slow speed, deep press for fast speed.
Experienced operators generally press the lifting button lightly when operating the lifting, and then press the lifting button deeply after the heavy object to be hoisted rises at a slow speed. This switches to a fast speed, and the same when a lower operation is required. The electric hoists can achieve the smooth and safe lifting and lowering of heavy objects by this way.
