ROBORIGGER
Rotate loads by radio and hold their position autonomously – up to 50 t, with no taglines.
The Roborigger is a radio-controlled load orientation system developed by our Australian partner Tensa Equipment and used on major projects worldwide by Multiplex, Rio Tinto, Acciona, Lendlease, John Holland and many others. It adds a solution to our product range that makes taglines unnecessary when positioning crane loads.
Combined with the Ludwig Hook, a single remote control lets you both orient and release a load – a fully radio-controlled lifting process with no personnel in the danger zone.
How does the Roborigger work?
The Roborigger hangs directly from the crane hook and rotates the load using inertial forces: a motor spins up a flywheel whose torque can be applied instantly in either direction. While the button is pressed, the unit rotates at roughly 10 degrees per second. Once released, the Roborigger autonomously holds the last set position — regardless of wind or other external forces.
An onboard load cell shows the weight directly on the remote control, logs every lift and flags overload events automatically. Every lift is pushed via Wi-Fi and 3G/4G to the Roborigger IoT platform, complete with timestamp, location, weight and a high-resolution image.
Key benefits
- No more taglines – no rigger needs to stand in the danger zone
- Increases crane and crew lifting efficiency by an average of 15%
- Typically pays back within 6–12 months, according to the manufacturer
- Keeps working safely at significantly higher wind speeds
- Integrated load cell, IP camera with photo and video streaming
- Combinable with the Ludwig Hook – orient and release from a single remote
Return on investment
According to the manufacturer, large projects have saved up to AUD 950,000 a year using Roborigger — through fewer wind stoppages, faster cycle times between lifts, and eliminating personnel needed to manage taglines. Clients report a 15% increase in lifting efficiency; at typical crane-crew costs of AUD 50,000–75,000 a month, that translates into real savings.
Models & technical data
Two load capacity classes cover most applications. Further variants and special configurations (e.g. the AF12 for very long components up to 300 t, or wireless release hooks up to 85 t) are available on request.

Use cases
- High-rise construction: facade and curtain wall installation, even at extreme heights
- Precast concrete panel, floor element and core placement
- Shipping & ports: loading and unloading containers and breakbulk cargo
- Tunnelling: positioning tunnel segments at the shaft
- Offshore and marine lifting with the rugged ARMR1500-50 variant
- Pipe handling and structural steel / precast installation
Used worldwide
The Roborigger is used on projects by Multiplex, Rio Tinto, Acciona, Lendlease, John Holland, Leighton, BHP, Qube, CIMIC, JRL Group and LTE Structures, among others.
„Roborigger has completely changed the way we handle the installation of our CORECUBE precast lift cores. Roborigger now controls the cubes and accurately orientates them for landing at height. It’s quicker, safer and far easier than using taglines. We are very happy with the solution and use it on all our projects.“
„Since we began using the Roborigger, our facade panel installation has doubled from 10 to 20 units per day, even at excess height of 140m. The ability to remotely control loads has not only improved efficiency but also eliminated the need for workers to be near suspended loads, significantly enhancing on-site safety.“
„The overwhelming potential safety outcomes are what sparked our interest in Roborigger. The device perfectly aligns with our overarching strategy to be safer by design and focus on critical risks, removing the need for workers to be in the proximity of a high risk activity.“
