Erecting machine operating procedures and precautions ( on )

First, when erecting machine moves longitudinally to do all the preparatory work , for once in place, not half-way stop .
Second, the bridge machine running vertically on both sides of the track corresponding to the level specified height and remain stable.hoist gantry crane Before , during and after each lateral outrigger orbit required level , and strictly control the spacing, three tracks must be parallel .
Third, in the oblique concrete beam bridge installation, bridge machine before , during and after walking round outrigger positions , left and right front and rear wheels to stagger , and its pitch angle can be calculated based on bias , so that may be in the same lateral outrigger wheels orbit - specific matters can contact with manufacturing units .
Fourth, the bridge machine crane carrying concrete beams longitudinally running, hand pull the front leg parts required gourd (5t) and sliding rails fixed to enhance the stability of tension .
Fifth , when installed on the bridge when going downhill ,overhead gantry crane erecting machine longitudinal displacement measures should prevent sliding . For example : the use of triangular iron for protection in the front and rear wheels , especially in the legs away from the beam end close, the shift to the attention of the control .
Sixth, erecting machine installation , you should always pay attention to safety checks, each mounting a hole must conduct a comprehensive safety inspection , identify problems and timely treatment to stop work in order to continue operations. Work with mechanical and electrical failures allowed .
Seventh, in addition , the installation does not allow overload operation, not oblique hanging enhance operations.
Eighth, the connection pin of the processing material requirements must be in accordance with the design drawings shall not be replaced with a low steel processing .
Ninth, erecting machine must be carried out after assembly retry crane lifting operation , can also be hanging concrete beam specimens after erecting machine and then run the place to begin the installation .
Tenth, in five more than the wind conditions, the non- job, you must use a solid bridge machine rigging and lifting crane ,  bridge gantry crane  to stop working when you turn off the power , to prevent accidents.
Eleventh , erecting machine in place must be strictly controlled longitudinal position sizes to ensure a smooth installation of precast concrete beams in place .
XII , as the case of the bridge erecting machine installation of large equipment, erecting machine operations must be clear division of labor, unity of command, to set up full operations staff, full-time and full-time electrician safety inspectors .overhead bridge crane Also, there are strict construction organization and measures to ensure construction safety.
