With the heaviest chassis in its class, the TUG 660 BELTLOADER assures years of dependable service in the most demanding ramp applications. The central mounted conveyor is elevated at both ends by lift arms that are activated by single-stage, double-acting cylinders. The front of the conveyor operates at heights between 43 and 170 inches (1.09 and 4.32 m) while the height at the rear of the unit can be adjusted between 13 and 37 inches (0.33 and 0.94 m). The unit is equipped with belt controls operable from either end of the conveyor and an interlock prevents the engine throttle from being advanced for adjustment of belt speed unless the Direction Control is in neutral. A guide on each side of the conveyor assembly can be retracted if a clear conveyor surface is required. A collapsible safety rail is fitted on the side of the conveyor and an emergency hydraulic pump is standard equipment.
