hydraulic synchronous lifting jacks mainly works on the principle of hydraulic pressure.
hydraulic synchronous lifting jacks have a hydraulic pump that is connected to the hydraulic cylinder of the jack by tubing. When the hydraulic pump works, the hydraulic oil will be transported to the hydraulic cylinder. With the continuous injection of hydraulic oil, the piston in the hydraulic cylinder begins to rise under pressure, and then pushes the jack rod to rise to achieve the jacking action.
hydraulic synchronous lifting jacks system is equipped with corresponding control system. This system can monitor the pressure, travel and speed parameters of each jack through sensors. When the lifting parameters between jacks are found to be different, the control system will adjust the hydraulic oil flow and pressure of each jack, so as to ensure that multiple jacks are lifted simultaneously. For example, in the overall upgrading of large Bridges or the installation of large equipment, the various lifting points are moved synchronously in this way.
1. Installation instructions
1. hydraulic synchronous lifting jacks Site preparation
- Select a solid, flat installation site to ensure that the ground can withstand the total weight of jacks and heavy objects. If the ground is soft, it should be strengthened in advance, such as laying steel plates or using sleepers.
- Clean up debris on the site, avoid debris affecting the placement and work of the jack, and ensure that there is enough space around the installation location to facilitate operation and maintenance.
2. Check the hydraulic synchronous lifting jacks
- Before installation, carefully check the appearance of hydraulic synchronous lifting jacks to ensure that there is no damage and no leakage. Check cylinder, piston, tubing and other key components are in good condition.
- Check whether the type and specification of hydraulic synchronous lifting jacks meet the working requirements, especially the carrying capacity and travel range. At the same time, check whether all components of the synchronous control system (if any) are complete and properly connected.
3. hydraulic synchronous lifting jacks
- Place the hydraulic synchronous lifting jacks smoothly in a pre-determined position, ensuring that the bottom of the hydraulic synchronous lifting jacks is in full contact with the ground and perpendicular to the lifting direction of the heavy object. When multiple hydraulic synchronous lifting jacks are used at the same time, measuring tools should be used for accurate measurement to ensure that the position and spacing between the jacks meet the requirements.
- If the hydraulic synchronous lifting jacks are equipped with fixed devices, such as anchor bolts or jigs, they should be properly installed and fixed according to the requirements of the manual to prevent the jack from shifting during the work.
4. Connect tubing and power supply (if applicable)
- When using hydraulic synchronous lifting jacks, make sure the tubing is clean and free of impurities and moisture before connecting. Securely connect the oil pipe to the hydraulic synchronous lifting jacks and the corresponding interface of the hydraulic pump station, and fix the oil pipe with pipe clamp or other fixing devices to prevent the oil pipe from falling off or leaking.
- For electric jacks, connect the power supply according to the installation requirements of the electrical equipment. Check whether the power supply voltage and frequency are consistent with the jack's rating, and ensure that the ground is good to avoid electric shock accidents.
5. System debugging (for synchronous lifting system)
- After all hydraulic synchronous lifting jacks and related devices are connected, enable the synchronous lifting control system. Calibrate the sensor according to the system operating manual to ensure accurate measurement of jack displacement, pressure and other parameters.
- Carry out no-load debugging to check whether the lifting and descending action of each jack is flexible and whether the synchronous control system can work normally. Observe the display data of the control system to confirm that the synchronization error between the hydraulic synchronous lifting jacks is within the allowable range.
Ii. Precautions
1. Safe operation
- The operator must be professionally trained and familiar with the hydraulic synchronous lifting jacks operation method and safety precautions. During operation, wear personal protective equipment, such as safety helmet, gloves, etc.
- hydraulic synchronous lifting jacks are strictly prohibited. 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 hydraulic synchronous lifting jacks, check the accuracy of the synchronous control system 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
- Regular maintenance of hydraulic synchronous lifting jacks, check the oil quality and oil amount of 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 work, clean the hydraulic synchronous lifting jacks and store them 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 synchronous lifting jacks), etc., so that the problem can be dealt with in an emergency.
