Trestles/galleries are load-bearing construction for the route of belt conveyors transporting material to various altitudes and at various distances, frequently between two facilities.
These are usually lattice-work constructions supported by pillars and featuring platforms with railings for pedestrian movement, service platforms, and lighting. Depending on the inclination angle of a gallery, platforms with plain lattice, anti-slip lattice, and steps are used.
. The construction of a trestle in case of long conveyors is adjusted to fitting a load stretching station, whereas in the place of locating drive and maneovre station and telphers, facilitating servicing the drums and drive, are optionally fitted.
