Stiffener Mounting Gantry

The Stiffener Mounting Gantry is designed to assist operators in accurately positioning and tack-welding stiffeners onto panels. An integrated welding power source and conveniently located controls ensure efficient tack-welding, improving both ergonomics and operator control. This enables safe, efficient work with consistent, high-quality results.

The Stiffener Mounting Gantry is designed to assist operators in accurately positioning and tack-welding stiffeners onto panels. An integrated welding power source and conveniently located controls ensure efficient tack-welding, improving both ergonomics and operator control. This enables safe, efficient work with consistent, high-quality results.

All you need to know

Without using force, the operator can accurately move the gantry, clamp lift and position the stiffener to the preferred location. When the stiffener is positioned accurately, the Stiffener Mounting Gantry maintains its position for tack-welding and applies pressure to push away any gap between the stiffener and base plate resulting uninterrupted welding upstream.

Lifting and pressing capacity

This gantry lifts stiffeners with magnetic force and presses them into place with controlled vertical pressure, guaranteeing accurate positioning for tack welding.

Integrated tack welding equipment

Each mounting gantry features onboard tack welding gear, allowing the operator to position and tack each stiffener directly from the gantry.

Faster, more consistent outfitting

Significantly reduces the time needed to place and tack stiffeners compared to manual handling — while improving alignment, repeatability, and eliminating the need for continuous use of overhead cranes during panel assembly.

Designed for operator control

Every detail of the gantry is designed with the operator in mind. From the intuitive handle controls to the smooth manual movement in all directions, the system enables fast, comfortable and precise stiffener handling — without the strain.

When size and strength matter

From heavy profiles to long panels, this machine delivers consistent results in real-world conditions — day in, day out.

Individually controlled magnet cylinders for varying stiffener heights

Individually controlled hydraulic cylinders

Each hydraulic cylinder holds a magnet and can operate it independently, enabling precise alignment and gap closing — even when stiffeners vary in height along the panel.
