Product Description:

STAYED-CABLE CANTILEVER TRAVELLER

Stayed-cable cantilever traveller is applicable to large-scale stay-cable
cantilever casting bridge with wide bridge deck, heavy and long segment. Most of
the componants concentrates on bottom frame and walking system. It has no main
frame, at the same time, the lift is done by the stay-cable of the bridge. Comparing
with other types, the sigle weight of stayed-cable cantilever traveller is heavier.

●Low gravity of front trancerse beam

●Applicable to large-scale stay-cable cantilever casting bridge with wide bridge deck

●Safe & easy operation, easy fixing, and safty during walking

●Big operational space under the main frame, and easy installation and removal

Q:Seven techniques of hanging basket
10.5. tube. When the concrete is vibrated, we should pay attention to avoid the bellows to prevent the vibration rod from leaking;10.6. to nap. Because of concrete pouring, the surface still paving asphalt concrete, in order to enhance the bonding between the deck and asphalt layer layer of political government must firmly on the concrete surface roughening treatment:10.7. maintenance. After the concrete pouring, maintenance to improve the strength of concrete and prevent the formation of fine cracks, has an important role. Therefore, water conservation should not be less than seven days.
Q:Are there any hanging baskets on both sides of the hanging beam 0
Down to the basket pre pressure, that is, 1# block, in the continuous beam hanging basket in addition to 0# block 1# is the heaviest
Q:Can the vertical prestress of the hanging basket be tensioned after the subsequent section construction?
Prestressed concrete structure, before the load in advance, put pressure on it, in the external load when the concrete tensile stress compressive stress produced in order to offset or reduce the load due to the tensile stress, the structure used in the normal circumstances does not crack or crack late.
Q:Characteristics of the hanging basket
Main features of hanging basket construction1 can bear the weight of the beam section and construction load:2 stiffness, small deformation;3 lightweight structure, easy to move forward;4 the scope of adaptation is large, and the bottom mould frame is easy to lift, which is suitable for different beam height.
Q:When the hanging basket method is used for the construction of continuous beams, the adjacent fast
1, have been pouring section (such as 0# block) of the end of the concrete to do all the processing of cutting hair.2, the first of two adjacent segments (such as 0# and 1#, 0# and 1 '#) all the longitudinal bars between the (steel web comprises a bottom plate, the roof and corresponding welding together).
Q:Hanging basket in the construction of the 2 block construction is also need to press it
6 when you walk in the basket, be sure to move smoothly.7 cantilever pouring concrete should be from the basket to the front of the basket to the end of the basket.8 jack is an important tool in construction, must be carefully maintained.9 walking system should be lubricated regularly.
Q:What should be paid attention to in the construction of cast in place box girder of long span bridge hanging basket
Preventive measures: with good insulation performance wood template (preferably professional manufacturers), have a certain thickness and stiffness of the template surface to be coated with special treatment, release agent, to ensure the quality of cast-in-place concrete.The contents of the above are based on the actual work of the students to meet the problem of finishing, for reference, if there is a problem, please timely communication.
Q:What is hanging basket construction
As the starting point of this section, the bridge pier is the center, and the concrete is filled by the hanging basket symmetrically
Q:Production and installation of hanging basket
8.4. plugged. The corrugated pipe is connected with the embedded steel plate, pipe and horn anchor plate hole is not less than 5 cm, corrugated pipe and anchor plate around with sponge tightly, prevent the cement mortar into the anchor plate in o
Q:Under what circumstances the use of hanging basket construction
In the reinforced concrete rigid bridge construction across the deep river, river, the busy traffic arteries, usually are used as hanging basket technology oh;
