Usage:
1. According to the weight center of gravity, choose the fixed placement of the cross, so that the lifting will not be overturned; 2. The area of the slat or the foot of the slat must be in contact with the weight when lifting and landing, so as to ensure sufficient strength to prevent the weight from slipping down. 3. The ground on the top of the slung should be solid, if the ground is soft, it should be added under the base, and the top of the slung should be placed in the center of the slung. 4. Before use, you should shake it by air once, from low to high, check if there is any stuck or abnormal phenomenon, and it can only be used normally.
Matters needing attention:
1. Please understand the weight of heavy objects and the use scope of the track hoist before use, and it is strictly prohibited to overload the machine to avoid accidents caused by equipment damage;
2. If the weight exceeds the rated lifting weight, multiple slings should be operated at the same time to keep even load of the top of the slings, consistent speed of rise and fall, and stable.
3. If the weight cannot be unloaded within a short time after lifting, auxiliary blocks equal to the height of the weight from the ground must be filled under the weight for support.
Working principle:
The track lifting machine (the top of the arm of the hand) is driven by the hand through the gear rotation, the shell up or down. When unloading or descending, the left pawl will turn the handle backward, manually controlling its speed
