Downstroke Movable Support System
13. Operating requirements and attention of Downstroke Movable Support System
The operators must read the instructions carefully, and stick with the regulations to operate the machine. The specific requirements are as following:
● Fasten the machine bottom with pier top and beam surface embedded parts while the support legs are working. The professional personnel must check it carefully before the next procedure.
● After finishing the poles’ installation, the professional personnel must check it carefully before casting the beam.
● No operations in the bad weather such as: strong wind, rain, heavy fog and icy snow.
● No operation and working if the wind force has exceeded grade 7. Take some protection measures to guarantee the machine’s stability when the wind force exceeds grade 11.
● Equip the lighting device when the machine operates at night in the working area and passageway to guarantee the construction safety.
● Make sure that the traveling rail is smooth without the obstacles. g, The operators must accept the professional training and achieve the operations certificates of special equipment.
14. The maintenance time and item of Downstroke Movable Support System
● After construction are finished everyday, the workers must check the following content: if the level of main longitudinal girder meets the requirements or not; the connection of bolts and pins are firm or not; the electrical wires are broken and extruded; hydraulic system is regular or not; the track joints are plain and smooth or not; the connection of position limiter of crane and trolley are firm or not; the rail clamping device is in the working position or not; bed timber is plain and stable and the size of gauge is right or not etc.
● The welding lines are checked every month ::upper and down chords of main girder , web plate, vertical welding lines of legs and the welding lines of connecting frame etc. The operators should stop working when the welding lines are broken or fatigue crack. When the users find the crack by eyes, but they can’t make sure the dangerous degree, so they should use the welding inspection instrument to test and then adopt reasonable steps to deal with.
● About the painting of structure which should be painted again every two years. The users should clean the primary surface by steel brush and pay attention to the welding lines before the structure are painted.
The lifting mechanism, traveling mechanism of crane and trolley, reducer of motor and steel rope of winch are lubricated and maintained according the rules of specification.
15. The disassembly and site-transferring steps of Downstroke Movable Support System
The dismantling, transferring scheme is opposite with the installation scheme. The procedures are as following:
● Choose the hoisting equipment according to the part weight
● Disassemble the special shape mould plate and pier top bulk mould
● Dismantle the wing mould plate
● Disassemble the side mould plate and poles
● Dismantle the base mould structure and plate
● Disassemble the cantilever beam
● Dismantle the main girder
● Disassemble the front and rear support legs and auxiliary support legs
● Loading and transferring
