Components · Load Zone Impact Control · Zone 01
At the load zone, falling material impacts the belt, off-centre loading unbalances it, and the belt sags between idlers — and every component downstream inherits the result. Tru-Trac impact beds absorb that energy and hold the belt flat across the loading length.
01 / Engineering logic
Absorb, support, seal — in sequence.
Tru-Trac specifies load-zone equipment around three control objectives, in sequence.
02 / Dynamic Impact Bed architecture
The architecture, up close.
The Dynamic Impact Bed is built for the hardest load zones — heavy aggregate falling from height. Where a static bed resists the impact, the Dynamic bed absorbs and dissipates it.
- 01
Dynamic energy absorption
Engineered to take heavy aggregates falling from 3.5–10 m, delivering maximum shock absorption and reducing the velocity of falling rock before it loads the belt.
- 02
Dynamic idler arrangement
Absorbs the peak of each impact rather than transmitting the full blow straight to the belt and structure.
- 03
Medium and heavy-duty frame
A 1300 mm bed, available in all belt widths, built for severe-duty loading.
- 04
Adjustable troughing angle
Sets to the belt's trough profile to support the belt and hold the skirt seal through the impact.
- 05
Painted frame
Corrosion protection across the life of the bed, with an arrangement designed for straightforward maintenance.

03 / The range
The impact-zone range, by duty.
Selection is by impact energy — lump weight × drop height — plus belt width, tonnage, trough angle and installation access. Every figure is from the catalogue; engineering confirms the final specification.
