Track

Track Part #: TR-5WT

The standard straight track is for use on the APS-438 and APS-438 LP. Standard track length is 5.0' (1.52m) and comes with 3 weld tabs, but custom length tracks can also be ordered. Tracks are set up by tack welding the weld tabs in place using the attached cut-line indicators for reference, and then bolting . (Tracks can also be extended using our Track Connectors)

Includes

Flex Track

Flex Track Part #: TR-FL

The Flex Track works on warped boiler tube panels and is useful on many other applications that include contour and serpentine surfaces. Components include a flexible track backing, studded rollers and a slotted, flexible top plate. Backing is simply tack welded to the application surface before attaching the top plate with bolts to perfectly match the bend of the back plate/application surface.

Includes

Connector

Track Connector Part #: TR-TC

Track Connectors connect lengths of straight track to extend travel and cutting distance. These connectors simply slide on the end of the track and do not require any bolting or fastening for installation.

Wrap tracks are used with the APS-438 LRC or the Universal Pipe Trolley with the APS-438 and APS-438 LP on cylindrical structures such as tube, pipe and tanks from 6.0” (1.8m) - 60.0” (18.3m). Track is easy to setup and can be adjusted/tightened for pipe with varying dimensions. Trolley’s for all saws can also be fine-tuned for smooth motion and firm mounting.
