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:The difference between cast in place and hanging basket construction
The carrying capacity of the hanging basket is limited, and the bracket can be set up according to the requirement.
Q:Hanging basket construction and demolition of blue construction should meet the following requirements
(4) for the increase in the basket on the facilities (such as anti canopy, cold shed, shaft frame etc.), must be on the overall stability of the hanging basket is checked, and shall not damage the hanging basket structure and change the stress form.(5) during the assembling process of the hanging basket, it is strictly prohibited to cut and enlarge the hole of the bolt at any time, and it is necessary to obtain the consent of the hanging basket design unit. It is strictly prohibited to carry out electric welding and fire on the steel bar of the finish rolling. All of the finished steel bars must be locked with double nuts.
Q:Can the vertical prestress of the hanging basket be tensioned after the subsequent section construction?
In order to improve the service performance of prestressed structure, during the construction to the structure of pre applied stress structures of pre compressive stress can be wholly or partially offset load caused by tensile stress, avoid structural damage. Commonly used in concrete structure, concrete structure under load is before, in advance to put pressure on it to make it in the outside load when the concrete tensile stress compressive stress produced in order to offset or reduce the load due to the tensile stress, the structure in the case of normal cracks or crack late.
Q:How does the prestressed tensioning in the construction of the bridge hanging basket?
After pouring a concrete, such as the strength of the aging period, the tension of a paragraph, and then continue to the next section of constructionSpecific construction process and other prestressed construction process the same
Q:Summary of hanging basket construction:
In the development process of long-span cable-stayed bridge, it is necessary to pay more attention to the problem and further explore the problem of the long cantilever asymmetric construction of prestressed concrete cable-stayed bridge. Attention should be paid to the change of mechanical model. 2 cable tension test and long cable stress relaxation
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:Unit price analysis of hanging basket service
First, you need to determine what you need, I can help you analyze!
Q:Continuous beam cantilever hanging perfusion, the most reasonable construction period is how long
And the weather is ideal. The highway is low, the theory is OK, the 12 days on the railway is the least time
Q:What are the characteristics of the suspension bridge
Continuous beam bridge hanging basket construction method. Therefore, for the hanging basket bridge can not answer.The answer is recommended by friends
Q:Cantilever pouring construction should pay attention to what
Prestressed concrete continuous beam bridge, continuous rigid frame bridge span and span rivers, valleys, so the main use of cantilever pouring construction. Cantilever pouring method refers to the construction of the bridge on both sides of the working platform, a balanced section to the middle of the cantilever pouring cement concrete beam, and the construction of the application of prestressing. The main equipment is a pair of walking hanging basket, pull anchor in Zhang and pier has connected mobile beam on the whole hanging basket, and binding steel formwork, pouring concrete, prestress are carried out on the. After the completion of the construction of this section, the hanging basket symmetrical move forward a section, the next pair of beam section construction, in advance, until the cantilever beam section pouring completed.
