A cage welding machine for the production of welded cages – The VTA series

The cage welding machines of the VTA series are designed for the production of cylindrical cages with and without bells. Upon request, additional shapes (e.g., oval or rectangular cages) can also be produced. The VTA is equipped with a cooling unit. The closed cooling circuit guarantees not only greater unit lifetime of the welding machine, but also prevents the generation of wastewater and the wasting of water. If necessary, the cage welding machine can be equipped for inverter welding. The inverter welding unit provides for extremely low power consumption values, a smooth loading of the power mains, uniform welding results, and optimal welding results – with low spark formation.

The cage welding machines are available with several levels of automation:

  • Automatic straightening and cutting of the longitudinal wires using the ESR rotor straightening machine
  • The automatic feeding unit loads the machine with the longitudinal wires
  • The inverter welding unit ensures clean and precise welding
  • The automatic winding wire cutter rounds out the cage production process by automatically cutting the winding wire
  • The fully automatic cage removal cart removes the cage and emplaces it
