COTS Crane for Nuclear Applications With MotoSuiveur Protection

Aerospace, Nuclear & Defence

The challenge

A Commercial-Off-The-Shelf (COTS) crane solution is a cost-effective and easy to maintain option for nuclear applications, but will not always provide the required safety and control standards that the sector demands for effective mitigation and prevention of emergency situations.

These can take the form of uncontrolled loads caused by hoist brake, gearbox, motor, or control system failures, including overspeed and overhoist scenarios. They require near-instantaneous action when detected, plus suitable recovery options to facilitate a safe return to normal operation.

The solution

SCX Special Projects has integrated a revolutionary load arrest device into a COTS hoist for use in setups where a bespoke solution is neither straightforward to maintain, cost-effective, or necessary.

The combination of the COTS hoist’s industry-proven technology and integral protection from the failsafe MotoSuiveur load arrest and recovery device delivers a verified nuclear crane solution that can fit the requirement of all budgets while preserving the highest operational standards.

A robust base

  • A COTS hoist is built for endurance, with its modularity enabling a wide range of lifting speeds, heights, and safe
    working loads
  • The heavy-duty electric wire rope hoist is mounted on a low headroom crab unit, incorporating overhoisting and overloading limit switches
  • MotoSuiveur device can be integrated into a wide range of COTS hoists of different sizes and capabilities, even when retrofitted

 

Industry proven

  • A COTS hoist brings the reassurance of tried-and-tested industrial reliability and ease of maintenance
  • Adding a MotoSuiveur device creates a simple, cost-effective, and fit-for-purpose solution to nuclear lifting challenges
  • MotoSuiveur meets the recommendations of the ONR’s Technical Assessment Guide 56 (TAG 56) for Nuclear Lifting Operations in addressing uncontrolled load scenarios

 

Unparalleled protection

  • The compact self-locking MotoSuiveur device is mounted directly onto the drum and follows the normal rotation of the hoist
  • Any abnormal operation will see the device automatically arrest the load, incorporating damping to ensure maximum protection
  • The integrated wheel and sliding worm drive prevents free-fall conditions from developing, safely and smoothly stopping a hoist barrel within 30° of angular rotation

 

Let's talk more about nuclear cranes.

The nuclear sector demands high levels of safety and integrity that cannot be fulfilled by commercial-off-the-shelf lifting equipment on its own. Our innovative engineering approach takes proven components from reputable manufacturers and combines them with innovative protection systems to deliver a verified nuclear crane solution.

We have decades of experience in engineering nuclear cranes. Talk to us today.
