Product Description

Efficient engine of logistics warehousing - synchronous lifting jacks: In large warehouses, goods are stacked and shelves are installed, which makes the process run quickly. The operation is convenient, and the workers can learn to use it in a short time. Rapid improvement, accurate positioning, save manpower and material resources, optimize the utilization of storage space, and contribute to the fast-paced development of modern logistics.

Working Principle

At the start of work, the power unit is energized, the hydraulic pump works, and the hydraulic oil of the oil tank is extracted, pressurized and injected into the jack cylinder. The piston in the cylinder rises under the action of oil pressure. The jack is equipped with an intelligent synchronization module with a variety of sensors and controllers. Sensors capture changes in displacement, speed, and pressure, and the signals converge to the controller. The controller dynamically adjusts the flow rate of each jack according to the synchronization strategy. Like large equipment installation, multiple linkage, using the controllable characteristics of hydraulic oil, to ensure that the support points are evenly stressed, synchronous lifting, and ensure the accurate positioning of equipment.

Installation Instructions

I. Installation Instructions

1. 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 device
- Before installation, carefully check the appearance of the jack 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 specifications of the jack 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. Jack placement
- Place the jack smoothly in a pre-determined position, ensuring that the bottom of the jack is in full contact with the ground and perpendicular to the lifting direction of the weight. For the use of multiple jacks at the same time, it is necessary to use a measuring tool to measure accurately to ensure that the position and spacing between the jacks meet the requirements.
- If the jack has a fixed device, such as anchor bolts or clamps, it should be properly installed and fixed in accordance with 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, ensure that the tubing is clean, free of impurities and moisture before connecting. Firmly connect the tubing to the corresponding interface of the jack and the hydraulic pump station, and fix the tubing with pipe clamps or other fixing devices to prevent the tubing 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 connecting all jacks and related equipment, turn on 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 jacks is within the allowable range.

II. Precautions

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.

Frequently Asked Questions

What is a synchronous lifting jack system?

It is an advanced hydraulic system that utilizes multiple jacks connected to an intelligent synchronization module. This setup monitors displacement and pressure variables to ensure large and heavy structures are raised or lowered completely evenly.

Why is ground preparation critical before installation?

Proper ground prep ensures that the surface can fully support the intense weights involved. If the ground is too soft, it can settle unevenly under pressure, disrupting the synchronization system and compromising safety. Placing steel plates or sleepers is highly recommended for softer surfaces.

How does the system handle an unexpected power failure?

For jacks equipped with self-locking mechanisms, the self-locking system will automatically secure the current height to prevent loads from dropping. If there is no self-locking unit, auxiliary mechanical supports must be positioned immediately to securely hold the load.

How often should the hydraulic oil be maintained?

The oil quality and level must be inspected regularly. If you notice any discoloration, debris, or contamination, the oil should be replaced immediately. Always top up the fluid level to the specified limit using high-grade hydraulic oil.

Can these synchronous lifting systems be customized for different load capacities?

Yes. The parameters table details various models ranging from 45 to 300 tons of safe working load. Depending on your project requirements, the system can dynamically adjust the linkage and synchronization strategies across multiple jack units.
