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.

Q:Is hanging basket equipment special equipment? Need to record it?
After the completion of the installation of special equipment, construction safety supervision station shall apply for registration procedures
Q:Tensioning sequence of hanging basket
The general situation is to pull the first part of the prestressed steel strand
Q:Characteristics of the hanging basket
The so-called hanging basket construction refers to the casting of Large Span Cantilever Beam Bridge, the use of hanging basket method, the local segmental cantilever operation. It does not need to install the bracket and do not use large crane. The hanging basket construction compared with other methods, has the advantages of light structure, simple and convenient, no heavy pressure, etc..
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:What is the bridge hanging basket through hole
Mainly refers to the basket itself on the track to move forward
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:Unit price analysis of hanging basket service
Do not know if you are a contractor or the contractor, is a general contractor and then do subcontracting work needs to do cost analysis
Q:Technical requirements for hanging baskets
Three the assembling and dismantling of the hanging basket shall meet the following requirements:1 hanging basket rod and the use of machinery and equipment (such as Jack, chute, hand hoist, steel wire rope, etc.), should be checked, the use of unqualified.2 hanging basket assembly should be symmetrical, timely and stable components, together as one, to prevent dumping wounding.3 hanging basket operation platform should be linked to the safety net, surrounded by a fence, there should be a special staircase.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 hanging basket assembly process, it is strictly prohibited to cut holes on the bolt hole, when the hole is necessary, must 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:Are there any hanging baskets on both sides of the hanging beam 0
First, the height of the test results. In line with the requirements do not pre pressure, followed by hanging basket construction 0# block is the most important, pre pressure pouring.
Q:Management measures of hanging basket
12.3. fence. In the hanging basket around the set of sealed guardrail, to prevent high-altitude operation, object tools fall wounding.12.4. body tie. The construction of the box beam is placed on the river, and the height is 8. 15 meters, in case of safety requirements for the construction of high-level personnel, tied to the waist belt.12.5, avoid the wind. When the wind up to 7 or more, the hanging basket construction must stop operation, 012.6. lamp. Due to the duration of the project is tight, almost two days and nights of continuous bridge shift work, night construction site must be equipped with adequate lighting to ensure the safety of construction personnel.
