Product Description:

STAYED-CABLE CANTILEVER TRAVELLER

Stayed-cable cantilever traveller is applicable to large-scale stay-cable
cantilever casting bridge with wide bridge deck, heavy and long segment. Most of
the componants concentrates on bottom frame and walking system. It has no main
frame, at the same time, the lift is done by the stay-cable of the bridge. Comparing
with other types, the sigle weight of stayed-cable cantilever traveller is heavier.

●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:Does the behavior of American Travelers help Form your opinion of How all Americans really are?
Americans USED to be much better hosts then guests. Now we are pretty much crap at each side.
Q:Summary of the hanging basket construction
2 the girder structure system of the main girder structure system can be divided into four different systems according to the combination of the girder tower and the cable tower:Floating system: Tower Pier tower girder girder consolidation, separation, in addition to support at both ends, all the rest of the cable suspended, this system does not provide effective support for the transverse beam, to the temperature shrinkage and creep force structure, the cross section deformation and internal force changes smoothly, uniform stress, but must be in the cantilever construction in the tower at the temporary consolidation.Support system: Tower Pier tower girder girder consolidation, separation, set the vertical support in the tower, a three span continuous beam or cantilever beam with elastic support, the latter is in a cross hinge or a hanging hole, a hanging hole to a certain length, in order to avoid the side load, resulting in hanging hole excessive tilt.Tower beam consolidation system: the tower beam is fixed and supported on the pier, the stay cable is an elastic support, which can be used for continuous beam or cantilever beam.Rigid frame system: the beam pier is mutually consolidated to form a rigid structure with multi point elastic supports.3 overview of cable-stayed bridge construction process: the construction of cable-stayed bridge erection method in general there are three common methods: support method, push method and cantilever construction method. The first two methods used in the early construction of cable-stayed bridge, the cable-stayed bridge grew up in modern, especially from the tower to the cantilever construction on both sides of the multi span cable-stayed bridge with missile, inclined cable segment support.
Q:Vertical embedding of hanging basket
. The steel wire mesh of the embedded steel bar and the roof must be fixed firmly
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:Can the vertical prestress of the hanging basket be tensioned after the subsequent section construction?
Prestressed concrete structure, before the load in advance, put pressure on it, in the external load when the concrete tensile stress compressive stress produced in order to offset or reduce the load due to the tensile stress, the structure used in the normal circumstances does not crack or crack late.
Q:What is the function of the rain - water hanging basket device in the rainwater collection system
The rain, rain interception hanging basket device on both sides of a basket, can regularly to take out the equipment to remove rubbish.
Q:What is the length of the bridge hanging basket construction?
The bridge hanging basket belongs to the cantilever construction, which can only be designed according to the bridge type, the design of the cable and the weight of the block
Q:Is hanging basket equipment special equipment? Need to record it?
Special equipment regulations on safety supervision of special equipment is the safety of life, the risk of large boilers, air compressor and the air storage tank, tunnel construction hoisting machinery (construction elevator, tyre crane, crawler crane, gantry crane, tower crane, bridge machine), hanging basket construction equipment etc..
Q:Production and installation of hanging basket
In the construction, the construction quality of the corrugated pipe is good or bad, how to ensure the construction quality of the bellows? The main management measures are as follows:8.1. inventory. Bellows transported to the construction site, to enter the warehouse room stacked with the lower part of the board pad high, not rain, prevent rust o8.2. examination. Before the installation of corrugated pipe, to check the appearance to prevent deformation, there are trachoma bellows installed inside the o8.3. seal. The joint of the two bellows joints, to ensure that the length of the joint is not less than 30 cm, the distance between the two ends of the same, sealed with sealing tape joints to prevent leakage of slurry o
Q:Construction of extra large bridge
Demolition of the main pier consolidation, temporary support - drop beam - pouring back wall concrete ---- the demolition of the whole bridge construction load - bridge and railing construction, installation of ancillary facilities - full bridge.
