Product Description:

RHOMBIC FORM TRAVELLER

The rhombic form traveller has the advantages of simple structure, clear
stress, big operational space under the main frame, and easy installation
and removal, etc..
The form traveller adopts wheels with bearing while rolling forward which
reduce the frictional resistance greatly during movement; At the same
time, the stainless steel paltes are welded on the rails which reduced
the frictional resistance bewwen the sliding bearing and the rails during
movement. The combination of these reduce the movement cycle of the
form traveler by simple and convinient operation.
In terms of safety, the form traveler is equiped with walking protection
system which guarantee the absolute safety during working. It’s safe, easy
and practical.

● 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:Are there any hanging baskets on both sides of the hanging beam 0
In the 1# pre pressure when the basket has been removed from the non elastic deformation, so no need to hang basket that is 2# block pre pressure.
Q:This paper puts forward the quality control points and methods of hanging basket continuous casting box girder
The key points of quality control: 1, hanging basket template (including the bottom mold and the side mold) elevation 2, hanging basket preloading ensuring the load quantity; 3, the hanging basket forward, need special attention, when the cradle walking the preparatory work before the improvement, check again walking and walking condition of anchor beam connection rod the bottom, hanging point should adopt steel wedge pad, and ensure the stability of suspension;
Q:How does the prestressed tensioning in the construction of the bridge hanging basket?
The post tensioned prestressed precast box girder is prefabricated by a prefabricated field or a prefabricated factory, and then transported to the site erection; (2) the post tensioned prestressed cast-in-place box girder is directly poured into the box girder and the prestressed tension on the bridge. Cast in situ prestressed box girder, according to the support structure is different, the full frame pouring box beam and hanging basket construction pouring box beam. The hanging basket construction is the use of suspension facilities, segmental mold hanging and binding steel corrugated pipe, installation, concrete pouring, wearing steel strand, stretching and grouting, the completion of a segmental box girder, a segmental box girder, until the completion of the entire construction segment.
Q:The construction of the hanging basket of the bridge needs to be pre - pressed in each suspension section
. After the completion of the construction of this paragraph, the hanging basket symmetrical move forward a section, the next beam section construction, progressive, until the cantilever beam section of the pouring completed.
Q:Why from the beginning of cantilever beam pouring cantilever end?
General joints are the final processing, in accordance with this principle, you can infer the front end (Yuan Duan) pouring, and finally deal with the old and new material seam problem
Q:80m hanging basket construction section of how to pull the longitudinal tensile reinforcement
Internal tooth block! You look at the construction plans will know.
Q:Hanging basket construction 0# block which is, can provide a schematic?
You said the first row should be aware of the 0# pier, 1# pier, pier number, generally starting from the first pier or abutment number. And said that the 0# block is the first section of a pier pouring. It is generally expressed as 1# pier 0# block, n# block n# block.You're not the structure of each row are single pier I understand refers to the single bridge, down line some bridge is separated, so that the bridge is actually two pieces of the bridge, such a position to the two hanging basket, so also on pier two downstream. If you encounter an elevated ramp, it may not be 2, there will be more.
Q:Production and installation of hanging basket
8..5. fixation. In the process of pouring, the anchor plate is easy to loose 1 shift. Therefore, the screws must be fixed on the head template o8.6. positioning. The positioning of the corrugated pipe should be based on the bottom of the corrugated pipe, according to the curve coordinates of the prestressing tendon in the design.8.7. welding. In the process of pouring the bellows lands will be produced in the floating phenomenon, therefore, the bellows in place, can be tied to a "n" type in steel pipe, welded steel bracket and firmly, spacing is generally 60 cm, bracket welding in the stirrups, stirrup below advance real pad o
Q:After the completion of prestressed tension grouting on the basket can move forward
[] the hanging basket is a walk along the railway activities scaffolding, hanging basket hanging in the already stretching and anchoring box girder, cantilever casting box girder formwork installation, rebar, pipe installation, concrete pouring, tensioning and grouting work were carried out in the hanging basket. When the construction procedure of a beam section is completed, the hanging basket is lifted, and the beam is moved downwards. Therefore, the hanging basket is not only the space of the construction equipment, but also prestressed tendons before the beam segment of the load-bearing structure, and now large, medium and large buildings use this equipment.
Q:What is the use of hanging basket
Are you talking about the construction of the bridge? Generally refers to the construction of continuous beams do not support the use of a special construction process
