Hydraulic jacks can be regarded as the "powerful players" in construction operations. They use liquid pressure to lift and lower heavy objects, and are an indispensable and commonly used equipment in short distance lifting operations. To ensure stable operation of equipment and safe operation, the following points should be noted when using hydraulic jacks:

Firstly, the selection and cleaning of oil must be strictly controlled. The appropriate type of oil should be selected according to the working environment, while ensuring that the oil is pure and free of impurities. Before adding, it must be filtered to prevent impurities from entering the hydraulic system and causing wear.

Secondly, during homework, it is necessary to ensure that the ground and contact surface are flat and stable. If the ground or contact surface is uneven during the lifting process, it can easily cause the jack sleeve to tilt and deform, thereby causing irreversible damage to the equipment.

Thirdly, it is strictly prohibited to use hydraulic jacks horizontally. The structural design of this device is suitable for vertical operation. Horizontal operation may damage the internal sealing ring, causing oil leakage and affecting the normal use of the equipment.

Fourthly, regularly inspect key components of the hydraulic system. It is necessary to focus on checking whether the oil pipes and other components of the hydraulic system are cracked, damaged, etc., to ensure that the hydraulic system is always in good operating condition.

In addition, it is recommended that the operation of hydraulic jacks be completed by professionals familiar with hydraulic systems, which can effectively improve work efficiency and fundamentally ensure construction safety.
