Technical information

With each field test, complete training in the safe operation of the machine was provided.

Additionally, operators and their supervisors were provided a copy of the Automated

Cone Machine Safe Operation documentation (Appendix D). Training continued on an

as needed basis during field testing. Technical support was a priority in order to facilitate

a successful testing period.

Caltrans’ interest in the ACM has grown strong; therefore, they have decided to acquire

the machine from the AHMCT Center. Field support will be provided by AHMCT

Deployment Support to facilitate Caltrans’ evaluation of the machine. Extensive training

was also provided for the Caltrans representative assigned to the machine. A transfer

document was prepared and is included (Appendix E) in this report.

2.7 Automated Roadway Debris Vacuum (ARDVAC)

As a result of the effort to commercialize the ARDVAC, a field test and evaluation phase

was not feasible. However, testing was conducted and supported along the AHMCT test

road. The support included the design of an analog control interface, contributing

information regarding current debris removal needs and removal processes, operation of

the machine, and assisting in the evaluation.

Initial testing was conducted along the AHMCT test road in order to observe the nozzle

motion and debris removing capability. A variety of debris was spread along the

roadway and then retrieved using the ARDVAC. Video footage of the testing was taken

along with still photographs.

2.8 Summary

Deployment support has provided a means to integrate prototype machines into the

workplace. Over the course of each supported project, reverse engineering changes have

been implemented to increase the robustness of the machines and serve as information for

future design considerations. In addition, valuable feedback from operators and field

supervisors has been gathered.

The primary work has involved preparing safe machine operation manuals and

conducting field training for the assigned crews. Furthermore, field support is provided

to address any machine failures or problematic operations. Repairs and modifications are

generally conducted in the field as soon as reasonably possible. Occasionally, more

involved modifications are conducted at the AHMCT facility and scheduled in between

field assignments.

Throughout the course of this contract, deployment support has worked closely with

Caltrans on several projects. The coordinated efforts of the AHMCT Center and the

Caltrans Equipment Service Center and Maintenance division will continue to grow,

enhancing the relationship and technology of projects developed by Caltrans and the

AHMCT Research Center.
