Cantilever segment launching gantry

Brief Introduction

The launching gantry is used to put the pre-fabricated segment
onto the pre-fabricated pier. It is a kind of crane with the main
function of lifting and transfer the segment to designated
position, but very different from the common crane. It’s more
strict than the common one and can be walked on. Launching
gantry can be divided into several kinds such as launching
gantry for highway, for common railway and for passengerdedicated
line, etc..

Advantage

◆ Equiped with protection system which guarantee the absolute safety during working. It’s safe, easy
and practical.

◆ Easy installation and removal

◆ Safe & easy operation, easy fixing, and safty during walking

◆ Simple structure, clear big operational space and high efficient.

Q:Bridging machine construction method? Common types of bridge machine: But it is very different from the general sense of the crane. The requirements of the harsh conditions, and the existence of the beam on the line, or called the longitudinal shift. Bridge machine is divided into the erection of highway bridges, conventional railway bridge, passenger dedicated railway bridge, etc..

Q:DJ180 bridge frame 40 m beam through the hole program.: Beam transport,Motor vehicle and host alignment,

Q:Now the high-speed rail bridge frame span of the beam: But it is very different from the general sense of the crane. The requirements of the harsh conditions, and the existence of the beam on the line, or called the longitudinal shift. Bridge machine is divided into the erection of highway bridges, conventional railway bridge, passenger dedicated railway bridge, etc..

Q:What should be done before the erection of the bridge girder: But what should be done before the erection of the bridge frame? Here for you to explain! 1, bridge erecting machine at the end of the bridge is ready to assemble the beam, should be placed in the bridge at the vertical track, in order to frame beam; 2, the bridge machine cantilever to the next bridge pier; forward process should ensure the stability of truss. 3, the bridge machine in the back of the four hydraulic cylinder at the same time out, so that the bridge machine in the rear of the car to drive, pull the drive car to change the direction of its movement, auxiliary personnel quickly laying the longitudinal track. The hydraulic cylinder is driven by a hydraulic cylinder.

Q:What is the difference between bridge and gantry crane: Mosaic good (girder girder hoisting a piece also has two tablets, user requirements set) on both sides at the same time on the leg lifting, erect, then workers quickly climbed up, tighten the screws, then the trolley to the main girder structure, just part of the installation on all OK.The main movement in the road: beam yard hanging template, hanging beam, frame beamRailway: beam yard hanging template, hanging beam, frame beamShipyard: hanging welded plateAlso used for cargo handling occasionsWrite bad, please forgive me

Q:How to weld the wet joint of bridge erecting machine: Specifically how much I do not know, but the specification can be found

Q:DJ180 bridge machine how to run?: Four. When the bridge crane carries the concrete beam, the front leg part of the bridge crane is required to be fixed by the hand pulling block (5T).Five, when installing the bridge with the upper and lower longitudinal slope, the longitudinal displacement of the bridge erecting machine should be prevented from sliding. For example: the triangle iron for protection on wheels before and after, especially in the leg from the beam end is near, shift to the attention of control.Six, after the erection of the bridge crane must be suspended hanging crane operation, but also can be used to test the concrete beam, bridge erection machine running in place to start the installation work.

Q:How many special operators do you need to build a bridge machine? What kind of special operations personnel should be held?: General bridge machine, the need for a total command, operator 2, mechanical, electrical, hydraulic engineer

Q:How long will it take to set up the 30 - meter girder erecting machine on the highway: Standard 48 meters, when considering the hole is more secure with a total of more than 8 meters, with a total of 56 meters. Welcome adoption

Q:I would like to know the working principle of JQ IV 160t/40m bridging machine?: Working principle: the front assembly, the central assembly and the longitudinal moving flat car assembly are equipped with rotary 0-45 angle of the rotating support to meet the requirements of the bridge girder oblique beam. When the bridge erecting machine is inclined to set up, it is necessary to pre install the central cross beam and the middle part of the roll, the front cross beam and the front roll, the trolley beam and the crane in the angle of oblique installation.
