Accessories & Related Parts
Lift Bars & Hook Guards
A-Frame braces for front structural support
Sub-frame rollers & mounts for body support
Finish options include powder coating; top longsill areas should be inspected/covered to avoid surface rust.
A SwapLoader sub-frame is the steel frame integrated into the container or body that interfaces with the hook-lift hoist. It ensures correct hook height, alignment, and enables secure lifting/dumping without misalignment or damage.
Match hook height, truck and hoist model, container length, and required durability. For instance, use the 100 Series for lower hook heights and smaller bodies; the 400 Series for larger containers with higher clearances.
No—basic sub-frames typically exclude body rollers, brackets, or hook guards. These are ordered separately to suit your specific needs.
Keep finishes protected (especially longsills), inspect lift bars and hook guards for wear, grease any pivot or moving parts, and ensure that rollers & mounts are aligned correctly to avoid excessive wear.
SwapLoader offers robust technical support, parts availability, and manuals. Warranty specifics can depend on model and usage—consult with your Tracey Road Equipment rep for full details.
