What is an idler frame?
It is the welded structure that mounts the idler rolls at the correct spacing and trough angle and bolts to the conveyor stringers.

Usage
Usage
H-Frame (Support Stand) — the vertical stand that carries the troughing idlers and holds the belt line at the correct height and alignment. As the backbone spaced along the route, its rigidity decides whether the belt runs straight and the idlers stay in plane.
Operating conditions
Operating conditions
| Working temperature | Ambient service range (-20 °C to +40 °C); the coating protects the steel, stainless for aggressive sites. |
|---|---|
| Dusty environment | Suitable — all-steel structure with no bearings or seals to contaminate |
| Moisture & water | Suitable — hot-dip galvanized or stainless frames for outdoor, port and washdown service |
| Corrosive environment | Powder-coated for ordinary acid or alkali · Galvanized for coastal and semi-outdoor · Stainless for high-salinity and high-humidity sites |
| Certification | MA coal-mine safety certified versions available — confirm the certified SKUs for your project |
| Outdoor use | Suitable — coated and stainless options for coastal and weathering service |
Technical overview
Idler frames and structures hold the rolls in alignment and transfer belt loads into the foundations. HBXM supplies carrying, return and training frames in galvanized or painted steel, cut and drilled to your belt width and trough angle.
How do I specify a frame for my conveyor?
Give us belt width, trough angle, idler arrangement and stringer spacing; we cut and drill to match so installation is bolt-on.
Are frames supplied pre-assembled?
We can ship loose sets for container savings or pre-welded frames for faster site erection, depending on your logistics.
Galvanized or painted steel?
Galvanizing suits outdoor and corrosive sites; painted frames are fine for enclosed or dry plants and cost less.
