Chernobyl Main Cranes System

Category: Robotics > Dismantling and Retrieval > Bespoke System
Reference # : Model No :

The main cranes system (MCS) integrates overhead bridge cranes, trolleys, and a remote control and video monitoring system for operating the cranes system in a radioactive area. The MCS will be erected and operated inside the New Safe Confinement (NSC) currently being constructed over the wrecked unit 4 of the Chernobyl nuclear power plant in Ukraine. It is allow for the dismantling and cleanup of the site in a controlled environment.

Comments

The MCS includes two 50-tonne trolley hoists that can work in tandem to handle loads up to 100 tonnes. A third trolley suspends a mobile tool platform (MTP), which utilizes a RoboCrane technology that was developed at the US National Institute of Standards and Technology (NIST) and is licensed to PaR Systems.

The MTP incorporates a Modular Suspended Manipulator (MSM), developed at NIST in the 1990s, which expands upon the principle of a Stewart platform, a device that uses three sets of paired winches (motor-driven spools of cable) to suspend and manipulate a platform with six degrees of freedom (lateral, longitudinal, vertical, roll, pitch and yaw). Stewart platforms are most familiar for their use as the base of flight simulators.

PaR will affix a variety of interchangeable tools to the MSM, including a robotic arm, drill, jackhammer, shear, high-power vacuum system, and closed-circuit television viewing system, all of which will be operated remotely.
