Nobles are partnering with Roborigger to bring their recently commercially released, patented crane hook auto-rotation control device, the AR10, to our customers. Roborigger is designed to allow the positioning and landing of lifted loads to be undertaken without the need for workers to be in the vicinity of the load. This reduces the risk to personnel and eliminates the need for tag-lines on loads.
Not only does the Roborigger create a safer working environment but it also improves productivity. Lifting operations can be completed faster without the need for tag lines to be attached or removed and loads are rotated in the air during the lift which means they can be lowered immediately once the position has been reached. Roborigger also makes challenging tasks easy and safe, for example, loads with large windage such as panels can be lifted in stronger winds giving significantly increased crane utilisation.
The Roborigger can position the loads when hanging on a single wire with a swivel, it does not need anything attached to it. The autorotating system uses inertia and gyroscopic forces from rotating flywheels to position the load, this is similar technology to that used to orient spacecraft. Controlled wirelessly using a handheld remote, it can be used in manual mode or can store two headings and automatically rotate the load to either heading using its control system. The unit has sensors which detect the rotation rate and the heading. The sophisticated control system ensures that the load rotation is controlled within strict parameters and that the unit can hold the load at a constant heading when required even if there is gusting wind.
The optional wireless release system allows the operator to release the load remotely. The system has inbuilt safeguards to prevent release under load and has a dual command system requiring two buttons to initiate a release. The Roborigger includes a video camera and load cell and is fully internet connected so all lifts are recorded on an online database complete with date, time, location, weight and a high-resolution image. Load ID can also be recorded.
Key features of Roborigger AR10:
- Ability to rotate and position load using a wireless remote control with 100m min range
- Optional remote hook release that requires two button press and will not release under load
- Camera that takes snapshots of all lifts and set downs as well as providing video feed to crane operator
- Ability to have two pre-set orientations to simplify repetitive operations
- Battery operated with capability to last at least 12 hours, batteries rechargeable overnight from a standard 240V power outlet
- Optional exchangeable battery module allowing 24x7 operation
- Minimal operator training required
- Integrated load cell with load readout on remote handset
- Inbuilt condition monitoring, lift logging and diagnostics direct to the internet.
AR10 Key Specifications:
- WLL: 10,000kg
- Size: 1400mm (diam) x 900mm(H)
- Weight: 720kg
Design, strength and safety
Roborigger is designed as a lifting appliance to AS 4991. ultimate strength = 5 x SWL. Each unit is load tested to 2 x SWL. The remote control complies with the Australian Crane Code AS1418 and includes all the safety features required for crane operation. The electrical system uses low voltage DC and does not require licensed electricians.
Training and Competence
To use Roborigger functionality, it is almost as simple as just pressing the clockwise or anticlockwise buttons. Experienced riggers and crane drivers are working proficiently within 10 minutes. A comprehensive training programme has been developed to cover prestart inspections, troubleshooting, basic maintenance and use of the internet monitoring.
How can you use Roborigger?
Roborigger can be used with tower cranes, mobile cranes, for installing wind turbine blades, lifting frames and spreader beams and for offshore applications. Nobles currently has an AR10 unit with fixed hook now available for customer trial/hire in South Australia (or interstate subject to application).
