Rad Tolerant Handling Equipment

TensileTruss Technology

PAR Systems’ TensileTruss technology utilizes a custom Mobile Tool Platform (MTP) which serves as a stable platform for remotely operated tools.

Our TensileTruss application is composed of two triangular shaped platforms, upper and lower, connected by six wire ropes and positioned by six hoists. The hoists raise and lower the platform and can sustain significant horizontal loads and torque generated by tools. This rigid platform provides an ideal delivery system for remote tooling that is required in long-term projects like the dismantling of the Chornobyl Nuclear Plant.

A unique platform for the movement of materials & equipment.

Key features & benefits include:

  • High side load capability
  • High overturning moment resistance
  • High rotational moment resistance
  • Anti-sway due to high side load capability
  • High lifting capacity
  • Self-fused during seismic events
  • Long vertical reach (engineered)
  • Compatible with multiple tools for one system
  • Operability in air or submerged
  • Proven up to 75 m (250 ft) extension
  • Capable of being radiation hardened to 10E8 rad lifetime for extremely high radiation resistance
  • Easy decontamination since all surfaces accessible
  • Remotely operable through wired or wireless controls
  • Less weight than equivalent-sized mast
  • Single failure proof

Highly customizable for specific applications

PAR developed TensileTruss™ technology to provide an advanced method of equipment deployment and lifting capabilities for nuclear and commercial applications.

What is TensileTruss?

The TensileTruss is a multi-axis equipment delivery platform that is based on an inverted Stewart platform but uses cables instead of struts. It offers the ability to work in very large workspaces while providing high stiffness and 6 degrees of freedom for the lower platform that typical cranes or telescoping masts cannot offer.
