1. Introduction
This machine is used for the assembly of
U-beam&Box-beam. Place the plates on the bracket with auxiliary centering
device. Motor drives gantry to travel; and the upper press cylinder and side
press cylinder press the plates to finish the assembly and tack welding.

3. Working principle
The machine is mainly used for U-beam and
box-beam assembly during production of U- beam/box-beam bay. Work-piece is put
on the conveyor with assistant alignment unit. Motor drives gantry into working
area. With down-stroke cylinder and side-stroke cylinder on the travel gantry,
the web and flange of work-piece are pressed, and spot-welded will be performed
on the pressed section. Via travel of gantry, manual spot-weld is carried out
along the whole length of work-piece.
4. Main features
The standard models of our U-beam&Box-beam
assembly machines have the following features:
 Gantry is the main body of machine. All the clamping devices are
arranged on the gantry.
Two motors via worm and gear reducer to drive two wheels travel
along the rail.
Rail is 38KG/m heavy duty rail.
All motion parts have lubrication system;
Main electric elements are ABB/Siemens brands;
