specific Embodiment approach
[0022] 1. On-site survey, determine the track installation position of the hydraulic jacking device and other matters, and formulate the installation plan.
[0023] 2. On-site assembly and testing of the hydraulic jacking device.
[0024] 3. Lifting and unloading of motor stator:
[0025] After the motor arrives at the site, the trailer loaded with the stator is reversed between the four hydraulic trolleys, and the two beams are moved so that they are above the hoisting ring of the stator, and two of the four movable lifting lugs on the beam of the jacking device are used ( The numbers are 1, 3 or 2, 4) Hang the wire rope and fix the wire rope on the hoisting ring of the stator, hoist the motor stator with packaging base to a position near the horizontal centerline of the motor, and make sure that the load side of the stator is facing the direction of the rolling mill.
[0026] 4. Lifting and unloading of motor rotor and installation of extension shaft:
[0027] Move the bea...
