[0036] During the implementation of the utility model, when lifting, horizontally moving and loading and unloading large equipment:

[0037] A single first jacking device or a second jacking device can translate and lift large equipment to achieve the purpose of passing through some culverts, bridges, pipe corridors and loading and unloading. Taking the second jacking device as an example, the second jacking device is raised, and after the large equipment is transported to the designated location by a hydraulic flatbed truck, the steel wire rope is used to hold the fixed point of the equipment by an auxiliary crane, and the fixed point area is protected with wood and rubber. The four second hydraulic jacking units of the second jacking device are controlled to synchronously raise the second lifting beam or lower the hydraulic flatbed truck, so that the equipment is 100mm away from the hydraulic flatbed truck, and the flatbed truck moves forward to the other side of the pipe corridor to stand by. Then the second jacking device is controlled to slowly lower the height of the second lifting beam so that the equipment is 50mm to 100mm off the ground, and the second mobile trolley is controlled to move forward synchronously to smoothly pass through the pipe corridor. Finally, the second lifting beam of the second jacking device is controlled to descend, and the equipment is unloaded onto the hydraulic flatbed truck, completing the goal of lifting, translation, loading and unloading, and transporting equipment.

[0038] When turning over a large device:

[0039] The cooperation of the first jacking device and the second jacking device can safely and smoothly flip the large equipment without damage. First, transport the equipment to the designated location, use a 25T crane and a boom truck to connect the sling / wire rope by bundling with lifting ears, and hang the two points on the same side of the equipment on the first jacking device and the second jacking device at the same eccentric angle and height. Operate the lifting beams of the first jacking device and the second jacking device to lift, stop after a certain height, and then simultaneously operate the first lifting beam of the first jacking device to rise, and operate the second lifting beam of the second jacking device to lower at the same time, so as to achieve the purpose of flipping the equipment.

[0040] When lifting or moving equipment over obstacles:

[0041] By cooperating with the first jacking device and the second jacking device, large equipment can be moved over obstacles such as bridges, pipe corridors, small equipment and buildings. The equipment is transported to the predetermined point, and the jacking short section of the first jacking device is controlled to synchronously rise the height of one module assembly, and then the four first hydraulic jacking units are moved by sliding tracks to raise the height of one module assembly respectively, and the modules are gradually increased until the saddle exceeds the top elevation of the obstacle by more than 100mm, and then move forward smoothly. When the equipment moves forward to a proper distance beyond the obstacle, two sets of second jacking devices are used to act on the equipment head and the front half of the saddle respectively. When the second jacking device is fully stressed, the first jacking device is removed and transferred to the other side of the obstacle for installation. When the first jacking device is stressed, the lifting beam of the second jacking device is lowered to allow the equipment to move forward. In this way, the second jacking device and the first jacking device are used alternately to allow the equipment to smoothly and safely cross the obstacle.
