Synchronized jacks, large-tonnage synchronized jacks are mainly used for the overall lifting of railway bridges, the synchronous lifting and lowering of large machinery and equipment, etc., with a large volume of the lifted objects.

The synchronized jacks prevent the tendency of a single jack to tilt when lifting heavy loads, which could damage the load and pose a hazard. When in use, a multi-jack synchronous分流 valve should be employed, ensuring that the lifting loads on each jack are balanced and that the lifting and lowering speeds are synchronized. It is also essential to consider that the ground may sink due to uneven weight distribution of the load, causing the load to tilt and potentially resulting in human-induced damage. The series of synchronized jacks are equipped with pressure retention and overflow devices to prevent overloading, and are fitted with safety valves to protect the synchronized jacks during safe operation and to safeguard the lifting loads. The pressure retention devices are particularly suitable for bridge construction where high pressure retention requirements are necessary during beam lowering.

Usage Instructions:

Ensure all parts are in good working order before use.

2. Adhere strictly to the specifications in the main parameters when in use, and avoid overloading or exceeding the limits; otherwise, when the lifting height or tonnage is concerned,

Exceeding the specifications can lead to severe oil leakage at the top of the hydraulic cylinder.

3. If the oil level in the manual pump body is insufficient, it is necessary to first add N33# hydraulic oil that has been properly filtered to the pump before operation.

4. Please refer to the user manual for electric pumps.

5. Choose a moderate center of gravity for heavy loads, select a reasonable fulcrum point for the jack, ensure the base is leveled, and consider the ground surface.

Soft and hard conditions, whether to use sturdy wood pads, ensure even placement to prevent sinking or tilting under load.

6. After jacks have lifted heavy objects, they should be promptly secured with support devices. It is prohibited to use jacks as support.

Use. For long-term support of heavy loads, please select the CLL self-locking jack.
