Description

Mechanical jack (also known as hand-cranked jack, rack jack);It consists of three parts: a rack, a gear, and a handle. It operates by moving the handle to raise or lower the rack; this is a common type of jack used in ordinary cars. It is not very large, making it easy to store. However, this also limits its maximum lifting weight.

Instructions for use:

1. Select the appropriate placement position based on the center of gravity of the heavy object to prevent tipping during lifting;

2. When lifting and lowering, the area of the sling plate or sling feet must be in contact with the heavy object to ensure sufficient strength and prevent the heavy object from slipping;

3. The surface where the top tray is placed should be solid. If the surface is soft, add padding under the base, and place the top tray in the center of the padding;

4. Before use, shake it empty once, starting from a low level and increasing gradually, to check for any blockage or abnormalities. Use it only if everything is normal.

Precautions:

1. Before use, it is necessary to understand the weight of the heavy object and the operating range of the road leveling machine. Overloading must be strictly avoided to prevent equipment damage or accidents.

2. If the weight exceeds the rated lifting capacity, multiple cranes must operate simultaneously to ensure uniform load distribution among them and consistent lifting and lowering speeds for stable operation;

3. After the heavy object is lifted, if it cannot be unloaded within a short period, auxiliary pads equal to the height of the object from the ground must be added under the object to provide support.
