Australian businesses working together to keep improving safety

Best of Breed innovation between Webbair and SITECH Construction Systems has produced a ground-breaking Dynamic 3D Motion Control System (SMC)

Webbair together with SITECH Construction Systems has produced a ground-breaking Dynamic 3D Motion Control System (SMC) thanks to extensive field testing and collaboration with Winslow Constructors. Most importantly, this technology is ready to go and is currently being rolled out on worksites.

This Best of Breed innovation is the direct result of industry collaboration between key Australian industry businesses who each have a commitment towards increased safety through continuous improvement. Together they have created a tangible innovative response to an industry need that is unparalleled in the construction sector. In their continued pursuit of excellence, Winslow Constructors dedicated both machinery and personnel to facilitate extensive field-based trials by creating mock-sites. This ensured on-hand expertise was available and real-life scenarios were considered with the technology being rigorously verified.

Winslow are industry leaders in the civil construction space and having the SMC solution in their stable shows their commitment to innovation and safety whilst maintaining productivity and efficiency.

“Adding this type of engineering control to our existing set of Safety Controls and Procedures (alongside our best-in-industry locating, exposing, mapping and modelling capabilities), will set us apart from the competition. It will significantly help us on our journey to continually improve safety.”

(Hugh Peck – General Manager Winslow Group Services).

Webbair Engineering Director Peter Stanley had this to say about the project. “An SMC type satellite-based 3D control system has been the Holy Grail for safety conscious companies for several years now. The project has thrown more than a few engineering roadblocks in our path and it’s very satisfying to finally see a product ready to go to market.”

The SMC system takes 3D motion control to the next level, providing full failsafe systems, dynamic in-field definitions of restriction zones, supervisor key lockout and is fully compliant in the rail industry based on the base motion control system which is already currently used by Tier 1 companies and rail providers nationwide. Using Webbair’s thorough knowledge and expertise of motion control requirements, this system ensures that no stone is left unturned and implements a safety-first procedure with true “proportional” machine control. Combining the industry recognised PME motion control systems and the Trimble Earthworks machine guidance solution means the system is built on proven technology and brings with it the respective productivity and safety benefits.

The SMC system will deliver robust engineering controls to keep machines out of any pre-defined high-risk areas and significantly reduce risk of sub surface service strikes that are extremely costly in both money and time. Allowing for the operator or supervisor to add in any new hazards or high-risk areas on the fly without requiring them to be defined digitally is potentially one of the biggest benefits of the system which was demanded from the market at the start of the due diligence phase.

Joe Lloyd from SITECH CS has been on the journey with Webbair from concept to completion and is incredibly satisfied with the result. “From the initial engagement with Webbair to signing the MoU, we have had a strong focus on delivering a real dynamic and flexible system that meets the requirements discovered during our due diligence process. One of the key elements to the design of the system was utilising the Webbair PME system to allow for dynamic limits to be entered manually in the field and locked by the supervisor. Having this functionality was imperative to keeping machines working under protection when new hazards were identified in the field. We are extremely pleased to be able to deliver this unsurpassed 3D motion control system to market. We would like to acknowledge the team at Winslow Constructors for their part in this success. Allowing us to rigorously beta test the system for the past 4 months in the real world was a real commitment from them, showing a dedication to improving and innovating in the safety space”.

Why the SMC Solution?

The PME400ME Component has the following features:

Full smart height limiting with ground reference sensors.
Slew limiting fully adjustable limits from cab.
Full virtual walls
Corridor setup and limitations
Maximum radius
Cabin protection, minimum radius
Dig depth control
3 colour touch screen
custom motion cut valves with emergency override facilities.
Supervisors key switch

Motion cut is provided to the following movements:

Boom Up
Boom Down
Arm In
Arm Out.
Slew Left
Slew Right
Blade Down (On Limitation where applicable)

Live Limitations that are setup in the digital design files: These limitations, or no-go zones, are predetermined at the planning stage of a site or added along the way as the site works progress. Obstacles such as power lines, bridges, buildings, geofences, underground telecommunications, gas lines, and electrical lines can all be built into the file and as the machine moves around the site it will be continually monitored through GPS and motion controlled to stop the machine from hitting any of the above.

The applications for such ground-breaking technology are endless and never has there been a solution for machines to be aided in control within the working environment from the planning stage right through to the completion of the project.

The SMC system provides the following features and benefits, all of which means the machine works as and the operator is always protected by the system ore readily aware when protection is less accurate.

Dynamically add limits in the field in real time; the system is not wholly reliant on updated digital designs being supplied. There is no need to wait for new digital designs to keep working under protection. Hence field employees are given with the full flexibility to adapt based on data received, whilst maintaining protection and maximising production times.
Fully proportional valve control means that the machines hydraulics are protected reducing wear and tear on the machine and the operator is truly safe in his seat without the risk of jolting or sudden unexpected movements.
Stops only the motion of travel that caused the alarm and allows that to be reversed immediately to come out of the danger zone. It does not lock up the whole machine or make the operator wait until he can remove himself from danger to be safe.
Full redundancy and manual override facility to ensure operator safety protection and ability move away from danger immediately.
Full fail-safe system with machine locking out with loss of accurate positional GPS data or any software crashes. This means the operator is confident he is protected all the times without having to focus on a screen and can’t miss a visual warning that could mean he is many metres out of position and allow him to breach exclusion zones.
Logging of alarm events for historical QA and safety incident reporting.
