Side guards may be provided along two edges of the frame to prevent movement of the
loads beyond the roller span. Side guards are particularly necessary at the curved sections of a conveyor.
(iii) Stands or Trestles: Stands or trestles support the conveyor frames with roller assemblies, from the ground. Stands are generally fabricated from pipes or structural sections, with provision for grouting on the floor. Height of stands are chosen to keep the articles at a convenient level on the conveyor.
Small portable conveyors often have telescoping legs for the stands, such that the inclination of the conveyors can be suitably adjusted in situ.
