The person is responsible for the electric pressure of the jack.
Site for people Jiang Gong told reporters, after all, the church has had a more than six years, experience near the tunnel construction, weather, rugged construction is decreased, the relocation back in the same place, Self Propelled Pallet Truck to reinforce the protection construction of the church board more than the previous more than doubled.
The church moved slowly on track bearing.
Reporters saw "packaged" below the church has a thick layer of fixed concrete support. This seems to a tray church firmly placed is 9 track at the top, the lower bracket convenient, Air lift table about half a metre wide track, up to 1 meter. In orbit above each about half a meter was placed a piece of wrist thick solid iron. Painted with lubricating oil, like a root bearing, the church is to be holding bracket, then the bearing track sliding forward.
According to the Jiang Gong. 6 years church before moving to the nearby, the bracket and the track was already pouring completed the, this just use the original most of the foundation, Hand lifter is a newly built into the site of part of the orbital, because before tunnel construction has been removed from a short.
Reporters learned that the first translation went out to spend about about 3000000 yuan, the shift back because of the use of some of the original facilities, the cost savings of half.
450 tons thrust a move 15 cm
How does the church drive it and keep a church that has a century of churches not destroyed? Reporters yesterday scene also saw an interesting scene.
In the south side of the church, electric lift table the nine track has nine jack, beside every jack has 2 to 3, 000 workers in charge of the scene, at the top of each rail also sat a worker, dedicated to the electric jack lost pressure. In front of them, there is a total command, holding a trumpet shouting three, one or two, and then hand press the electric switch, 9 Jack together with force, move the house forward. Reporters to the naked eye is difficult to find the house in mobile, electric stacker but can see the ground on a rope in slowly straightened, moving house will be some small debris falling sound.

the load should not exceed 70% from the weight allowed
weight lifting and lowering speeds should be smooth, uniform, not sudden braking; should balance the right and left to rotate when the rotation is not completely stopped before for no reverse action; lifting at full load or near full capacity, the non-landed arm rod or two actions simultaneously.
lifting objects should pull the rope slipped, the speed should be uniform, prevention of sudden braking and changes of direction; operation controller may not be directly transform the direction of rotation.
when the (track) Cranes For travel with load, the load should not exceed 70% from the weight allowed, walking roads should be solid flat, heavy crane is the former should be the direction of the weight off the ground no more than 500mm, and should be tied good rope, slow moving; non-load driving long distances. Cranes soft ground is not flat, lifting ban two simultaneous movements.
with two or more cranes Hand lifter lifting the same weight, the rope should be kept vertical; each crane lifting, running should be kept synchronized; each station machine heavy machinery to withstand load shall not exceed the rated lifting throughout capability. If not reach the above requirements, should be reduced to 80% of the rated lifting capacity; also be reduced according to actual situation Engineer rated lifting capacity to use. Hanging with time, chief engineer should be present guidance.
crane safety device malfunction, failure or incorrect operation when prohibited ill; in the job, is strictly Electric store Positioner prohibited on transmission parts, moving parts and moving parts house and area to do repair, maintenance, adjustment, etc.; transmission parts should be lubricated Good.
there are six or more in the open air winds or heavy rain, snow, fog and other inclement weather, they should stop lifting operations. After rain and snow before the job, you should try hanging, sensitive and reliable confirmation brake before starting work.
when the height of the lifting operations or the driver can not clearly see that the job location or signal set signal transfer personnel. Lack of natural light in the open place of work or work at night, they should be provided with sufficient lighting
