Product Description:

TRIANGULAR FORM TRAVELLER

Trianngular form traveler has the advantages of low gravity of front
trancerse beam, safe & easy operation, easy fixing, and safty during
walking, etc..
During the designing of the form traveller, we always provide
different modes of traction, such as hydraulic pushing mode or
pulling mode, and chain hoist mode, etc. to the constructors for their
choice.
The design of the form traveller could be divided into two types:
external sliding girder and self-moving exteral formwork according to
de construction conditions. When the site condition does not allow
to remove the form traveller at the closure part which have to go
backwards to segment, the second type is suggested.

● 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:There are several construction methods of bridge hanging
The front fulcrum hanging basket is commonly used in the cantilever construction of the concrete cable-stayed bridge, the main bridge company has its own design of the patent before the fulcrum hanging basket. The construction of the specific process for stitching the hanging basket, hanging cable, the first half of the cable tension, pouring concrete, second tension cable, half of the rest of the concrete pouring, third tension cable, then demoulding version of push hanging basket, the construction of the next section, repeat.
Q:Hanging basket construction and demolition of blue construction should meet the following requirements
(1) hanging basket and the use of machinery and equipment (such as Jack, chute, hand hoist, steel wire rope, etc.), should be checked, the use of unqualified prohibited.(2) the assembling of the hanging basket should be carried out symmetrically, and the components can be firmly connected in time to prevent the dumping.(3) hanging basket operation platform should be linked to the safety net, surrounded by a fence, up and down should have a special staircase.
Q:Construction technology of bridge hanging basket
D, the crane will be used to bridge the bottom of the bottom of the platform to lift the platform, and with the front sling, and then install the rear sling;D, installing the rear cross member and rear outer belt;E, to the basket to pre pressure to eliminate the plastic deformation, determine the size of elastic deformationF, the installation of internal and external model walking beam and to the 1# position;
Q:What are the key processes of hanging basket construction
1, Block 0 (support) frame construction;2, bearing and temporary consolidation system construction;3, hanging basket construction;4, concrete pouring construction;5, prestressed construction;6, beam body linear control;7, closure section construction and system conversion.
Q:Construction technology of hanging basket construction:
The construction of a steel cable-stayed bridge, most of the factory welding process, transported to the site, with the crane as a whole lifting, or block lifting, in place after the formation of high-strength bolts.Two construction of concrete cable-stayed bridge with cast-in-place and precast assembly and other combinations of construction technology. 1 the installation elevation of the hanging basket should be in strict accordance with the designed value.
Q:The construction of the hanging basket is not every section of the pre pressure
The second step: in the 0# block 1# block assembled hanging basket hanging basket -- 1.2 times the pre load pressure (first), observation, uninstall the pre camber adjustment, bottom plate and web of steel processing and installation, bottom plate and web prestressed pipe laying, installation of roof - mandrel steel processing, installation, installation of prestressed pipe roof 1# block, concrete pouring, the symmetry conservation tension in this section of the longitudinal and transverse steel beam and a vertical section of the finishing rolling rebar and anchor sealing and grouting.
Q:What should be paid attention to in the construction of cast in place box girder of long span bridge hanging basket
Main cause:1) no sprinkler health;2) the thermal insulation performance of the template is not good, the temperature difference between inside and outside is too large.
Q:The definition of hanging basket construction, historical background
With the development of material science and computer science, a lot of cable-stayed bridges have been built at home and abroad since the Stromsun bridge in 1956 started the apex of modern cable-stayed bridge. The cable-stayed bridge has been developed rapidly because of its advantages such as large span, good structural performance, simple construction, easy maintenance, low cost and attractive appearance.
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:The effect of hanging basket
Won a good corporate image and reputation. At the same time, this paper summarizes the experience in the construction and management of the hanging basket, which lays a good foundation for improving the construction quality and management level.
