Portal & Gantry Systems
Project-specific gantry systems that carry the robot to the workpiece for ship panels, transformer tanks and heavy steel.
What the system does and how it is engineered
On large workpieces the part stays put and the robot travels. Robentex portal and gantry systems are engineered with axis lengths from 12 to 36 metres, carrying the robot to every point of the part and correcting paths against real geometry via laser seam finding.

12 m X Gantry
Column Gantry Robotic Welding System
Robotic welding of large machine bodies within a 12 m × 3.5 m × 3 m envelope, with laser seam finding and offline programming.

24 m Slider
Twin Inverted Robots on a 24-Metre Slider
Two robots work in sync on HEB600 class profiles; both sides of a long beam are welded simultaneously and the part is never turned.

9 m Gantry
Inverted-Robot Gantry Tray Welding System
Access to every inner and outer seam on trays up to 3,000 × 1,800 × 400 mm, with two L-type positioners alternating.

Twin Cells
Dual-Cell Tank Welding System
Two robots, two gantries and four positioners; X-Y-Z gantries reach every face of the tank while laser seam tracking follows the joint live.

20 m Slider
20-Metre Slider Side Wall Welding Line
20 metres on X and 1,200 mm on Y: several build areas are served by one robot, welding side walls up to 4 metres wide.

Panel Line
Twin-Robot Panel Welding Portal
Two robots travelling along a bridge over the panel table, with a walkway platform, torch cleaning stations and perimeter guarding built in.

Scans · Analyses · Plans the Path
Four-Camera Scanning Portal for Shipyards
Four cameras on the bridge scan the part, analyse it and determine the weld path themselves. Developed specifically for shipyard conditions.

Runway Mounted
Twin-Robot Portal on Building-Mounted Runways
The portal runs on runway beams fixed to the building columns instead of its own legs, so the floor stays clear for crane access.
