TELEOP AND RRC FOR UNEXPLODED ORDNANCE CLEAN UP

ABSTRACT

A full-service demolition, environmental remediation, and construction contracting firm, specializing in all phases of hazardous waste management, site/plant cleanup and closure, and general engineering construction projects, implemented Hard-Line’s Teleop Control Station and Radio Remote Control for a live ordnance remediation project and decommissioning of a military base in New Mexico. The environment of the site presented considerable risks that required a solution to safely execute the objectives of the project. As a result, the client successfully completed the job safely, by removing the operators from the hazardous work zone and increased the utilization of its assets. 

INTRODUCTION

Hard-Line’s Teleop Control Station (Teleop) and Radio Remote Control (RRC) technology allow operators to control machinery from a remote or distant location. Hard-Line customizes its systems for any heavy industrial machines, so mixed fleets of various manufacturers are not a problem.

The client applied the use of a Teleop Control Station and RRC for use on a live ordnance remediation project and decommissioning of a military base. The work consisted of the removal of hazardous materials that presented high-risk scenarios, such as loss of life and damage to the company assets. The primary reason for using Hard-Line’s technology was to ensure the safety of its workforce. The secondary reason was the fact Hard-Line had the experience in installing the technology in various machine types and brands over one system and network. The Teleop and RRC systems allowed the heavy equipment to be operated from a safe location while excavating the dangerous materials from the site, ensuring the safety of the workers.

APPLICATION

The client was contracted to screen an entire field for unexploded ordnances. The field had previously been a training facility for the military, where trainees would launch grenades and mortars into the field during practice. The area required rehabilitation because of mandatory re-purposing of the land. The project entailed a Kawasaki 95ZV loader and a Link-Belt 460LX Excavator to be fitted with Hard-Line’s RRC and Teleop technology. The initial installation took place in California and afterward shipped to New Mexico for use on the military project. The project required the control of the machines from two separate locations.

The installation included the network and system to allow for the operator to teleoperate the excavator from a trailer, located 1 km away from the site.
The loader was equipped with the RRC system and was set up in a sea-can surrounded by thick concrete walls.
The walls were necessary due to the enclosure being in such proximity to the working area. A real-time video stream was sent wirelessly back to the sea-can using an extended line of sight video solutions. This entailed strategically placed cameras in the work zone to allow the operator to have visual coverage of the machine and its surrounding environment. Overall, these machines, with the additional technology, worked perfectly as expected, for the entire project length, start to finish. The remediation process involved the teleoperated excavator to excavate the area and load the material into an armored truck. The truck then dumped the material into a stockpile where the
