Synchronous lifting overcomes the single jack lifting weight should be inclined, resulting in damage to the weight and produce danger.
Synchronous lifting uses multi-top synchronous shunt valves, and the load of each top is balanced to keep the speed of lifting and dropping synchronously. It should also be considered that the ground may sag due to the uneven weight of the lifting object, which may cause artificial damage.
Synchronous lifting is equipped with pressure retention and overflow device to prevent overload, and equipped with safety valve to protect Synchronous lifting to achieve safe operation and the purpose of protection of lifting objects, pressure retention device is more suitable for the bridge construction with high pressure requirements of falling beam
