Bridge girder frame work process and precautions (part 2)
(3) Lifting beam
① any time before hanging beam operation, try hanging once required. After tying the beam that should be first winch brake test for 2 to 3 times, and then lift the beam a little, check whether the quit rope, iron tile or without guard beams move and jump off, etc., before the official confirmation reliable operations.
② hoist lifting beam should be the same action, even by force. Prevent the emergence of hoist partial load is too large and violent swing beam and so on.
③ beams when lifting, walking and falling, should be kept level. Should alignment in a timely manner If found tilt. Sometimes in order to facilitate the falling beam, allowing there be a small amount of vertical tilt, but not too large.
④ When walking beam to prevent chaos and hopping around the rope, cables are crushed and its breaking phenomenon. Impact of walking beam must be cleaned of all kinds of obstacles.
⑤ should walk in the high beams. Easy to cause collision accident prone if it walking swing in the low volume.
⑥ beam should let someone go in PIERS monitoring beam operation. Especially beams in place soon, PIERS surveillance personnel, command staff, operating drivers to be especially careful and close cooperation to prevent beams hit the front leg. Piers surveillance personnel necessary to pull the limit switch, to ensure safety.
⑦ not overloaded crane girder bridge machine.
(4) off the beam
① Do not drop the beam into position to take appropriate measures on the lateral roof, pull, to prevent accidents.
② off when the beam must be hand pull gourd in front, the back-end to take protective measures. Chain hoists to hang on a firm place.
③ beam to fall from 200 ~ 300mm seat when the seat and make sure that the device is ready and then continue sliding off the beam.
④ off the beam when seated at one end of the two jack ups and downs should be synchronized to prevent beams deflected accident.
⑤ When erecting machine traverse beam, there should be someone to monitor traffic traversing a small, rear beams in place, the application of forest wedge or wheel stopper will traverse a small lane walking wheel fixed to prevent slippage small lane.
