Welcome to SHIJIAZHUANG BO XING MACHINE CO., LTD.
Automatic 3D Lattice girder production line, truss girder welding line
● The plant is controlled with a system which is reliable, powerful and flexible and controls all the functions of the machine and allows an easy interface with the operator. The main computer has a diagnostic system which allows an immediate check of all the signals emanating from the machine.
● All the axis parameters, machine times and speeds are adjustable from the computer.
● The programming is quick and easy so as to be as user friendly to the operator as possible.
● The welding is controlled by units which allow the operator to adjust and change the periods and the power relative to the production at hand.
● All the power apparatuses for driving the motors and all other functions are mounted in the electronic switching cabinets; all the signal lights and the various commands are found on the cabinets.
● The operator controls the plant through the electronic control stations which are positioned appropriately.
