Vacuum Track System

Promotech’s vacuum fixing system provides firm grip of rail tracks on both ferromagnetic and non-ferromagnetic materials. Lightweight and modular design enables easy adjustment and fitting of the system to specific needs depending on welding or cutting applications and working positions (e.g. flat, horizontal, or vertical). A vacuum fixing system can be applied to both rigid and semi-flexible tracks to enable usage on surfaces with a radius of more than 5 m (16 ft).

  • Back up a reservoir for added safety in case of a power failure; a back up vacuum offers additional time to safely secure
  • A welding tractor and tracks; also greatly reduces the installation time of the whole system
  • Maximum plate temperature up to +320°C (608°F)
  • Only 100 mm (4”) minimal distance from the heat source to the vacuum pads

Vacuum Track System

Up to 4 rails can be connected separately for rail leapfrogging during operation

The permitted load is up to 30 kg (66 lbs) – welding/
cutting tractor with accessories.

Semi-flexible track enables fixing on curved surfaces with a radius of at least 5 meters (16ft)

Specification

Promotech’s system consists of a vacuum pump that generates vacuum and of vacuum units that fix the semiflexible or rigid track to the surface. A single pump provides gauge pressure sufficient for up to 21 vacuum units. A single vacuum unit provides suction power of 1400 N (at gauge pressure of –0.7 bar / –10 psig). The permitted load is up to 30 kg (66 lbs) – welding/ cutting tractor with accessories. Semi-flexible track can be fixed on flat or curved surfaces with a radius of at least 5 meters (16 ft). An optional manifold can separately connect vacuum units of up to four rails, what allows rail leapfrogging during operation. Temperature of material on which vacuum pads are used cannot exceed +320°C (608°F). Heat source must be kept at least 100 mm (4″) away from vacuum pads. Safety eye bolts are provided to suspend vacuum rail tracks and protect them against accidental fall.
