● Synchronous pushing: Move the main transformer out of the station and out of the tooling, and use the rail clamp with push and pull hydraulic cylinder
● Aiming: Due to the main transformer is too close to the surrounding wall, the personnel cannot carry out the construction. Only when the main transformer is moved out of a certain distance can the staff facilitate the operation.
● Synchronous lifting: 4 synchronous lifting hydraulic jacks are installed around the main transformer, once the hydraulic system gets started, adjust the cylinder, synchronous lifting of the jack is well controlled, the main transformer is jacked to the height of the base caster where it can be removed, and the cushion block is placed in the corresponding position as a safety guarantee.
● Dismantle the base caster: the walking wheel which was used previously has now become a burden to the bearing capacity and long-distance walking, so it had got to be removed。
● Walking: Drive the platform trolley into place and descending the jack, let the main transformer fall into the platform trolley, start the walking function, until it has reached to the area where track is changed, the motion stopped.
● Reversing: First, use the synchronous lifting system to stabilize the transformer and start the trolley to support the jack, so that the rim of the walking wheel falls off the track, which is convenient for the caster to change the position. When the rim of the caster stops rising after coming off the track, turn the caster directly above the guide rail perpendicular to the current track and slowly retract the support jack until the power trolley falls steadily on the vertical track. Finally, the synchronous lifting system is launched again and the transformer back on the transport vehicle again.
