The work of the synchronous lifting jack begins with the operation of the power source - the hydraulic pump. The hydraulic pump pressurizes the hydraulic oil and transmits it to the hydraulic cylinder chamber of the jack. In a hydraulic cylinder, the pressure generated by the hydraulic oil pushes the piston up along the inner wall of the cylinder. This upward thrust is transmitted through the ejector rod to the weight to be lifted. In order to achieve the effect of synchronous promotion, it is equipped with an intelligent control system. The sensors in the system are distributed in the key parts of each jack and collect information such as position and speed at any time. According to these data, the control system accurately controls the oil intake and return process of each jack, that is, the flow and pressure of the hydraulic oil are adjusted. In this way, each jack works under the same or predetermined lifting parameters to achieve the synchronous rise of heavy objects, effectively avoiding structural deformation or imbalance caused by unsynchronization.

1. Safe operation
- The operator must be professionally trained and familiar with the operation method and safety precautions of the jack. During operation, wear personal protective equipment, such as safety helmet, gloves, etc.
- It is strictly prohibited to use jack with overload. Before working, it is necessary to accurately estimate the weight of the heavy object and ensure that the carrying capacity of the jack has sufficient safety margin. At the same time, during the lifting process, pay close attention to the working state and load of the jack, and stop the operation immediately once an anomaly is found.
2. Synchronous maintenance
- For synchronous lifting jacks, the accuracy of the synchronous control system should be checked regularly. If the synchronization error is found to exceed the specified range, adjust it in time. In the working process, try to avoid external factors to interfere with the synchronous work of the jack, such as uneven ground settlement, external force collision and so on.
- When multiple jacks work at the same time, the load distribution of each jack should be as evenly as possible. This can be achieved by pre-adjusting the initial height or load of the jack to ensure the stability of synchronous lifting.
3. Equipment maintenance and maintenance
- Perform regular maintenance on the jack, check the oil quality and oil amount of the hydraulic oil (if it is a hydraulic jack). The oil quality should be replaced in time, and the insufficient oil should be added to the specified liquid level. At the same time, check whether the seal leaks, if there is a leak to replace the seal in time.
- After the work, the jack should be cleaned and stored in a dry and well-ventilated place. Avoid exposing the jack to damp and corrosive environment for a long time to prevent parts from rusting and damage.
4. Emergency handling
- Remain calm in case of power failure or equipment failure during hoisting. For jacks with self-locking devices, rely on the self-locking function to prevent heavy objects from falling. If there is no self-locking device, take emergency measures, such as using auxiliary supports to support heavy objects, to avoid danger.
- Prepare the necessary emergency tools and equipment, such as backup power supply, hand pumps (for hydraulic jacks), etc., in order to be able to deal with the problem in an emergency.
