Product Description:


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.

Q:How to deal with the cracks in the box girder
Your cantilever cast-in-place box girder is not prestressed construction.Need to identify the type of crack, if it is hot up cracks or superficial expansion cracks, the depth of not more than 2mm, not to the vertical and horizontal direction of development is not related, you can not deal with.
Q:The construction of the hanging basket is not every section of the pre pressure
The construction of the hanging basket is not the pre pressure of each section.Hanging basket construction steps are as follows:
Q:The post tensioned prestressed anchorage of suspension bridge can be reused?
Prevention of shrinkage and stress loss of prestressed reinforcement
Q:There are several construction methods of bridge hanging
The rear support hanging basket is commonly used in the cantilever construction of continuous beam bridge or continuous rigid frame bridge. The construction process includes the 0# block after concreting, splicing hanging basket, splicing template, binding of steel bar, concrete pouring, and then remove template, tensioned, pushed into the construction hanging basket in the next section so few steps, again.
Q:What is the meaning of "hanging basket" in building construction
Through the wire rope and special tools for lifting, standing on the platform to operate.
Q:Can the vertical prestress of the hanging basket be tensioned after the subsequent section construction?
Yes, but it should be decided according to the drawings.
Q:In the construction of the bridge hanging basket, the temporary prestress
Slightly under the pull, the clip is loosened, the jack to the starting point of less than the place on the clip
Q:Vertical embedding of hanging basket
Reinforcement and reserved holeIn the hanging basket after the anchor system of the embedded 32 finish rolling screws must be kept vertical, strict inspection in the management, so that the same axis
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: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
