Volquetes articulados(fuera de camino)
Operan en caminos húmedos o fangosos debido
su excelente tracción.
Recomendados para situaciones donde no es
económico construir un camino adecuado
(trayecto muy largo o trabajos de corta duración)
Su maniobrabilidad es usualmente menor que la
de un volquete rígido de similar tamaño.

Remolques para traíllas
Ambos remolques, el de descarga posterior y el de
descarga por el fondo pueden ser tirados por la
unidad motriz de un traílla autopropulsada.
La maniobrabilidad es excelente debido a que la
articulación puede girar 180° y cada unidad
puede operar fácilmente en condiciones muy
restringidas ejem. Excavación de un túnel.

Cargadores de ruedas
Solución mas popular para cargar todo tipo de
volquete y camión.
En proyectos de pequeña o media dimensión, ellos
se pueden movilizar rápidamente de un área a
otra.
Acarrean material económicamente, recorriendo
distancias hasta de 200 m. eliminando la
necesidad de transporte en esos casos

Cargador de orugas
Mas difíciles de operar que las de ruedas.
No aptos para recorrer distancias largas. No
superan los 12 km/hr.
Han perdido popularidad
Se tiende a usarlo mayormente en aplicaciones
