Company: Roadtec Inc.
The SB-2500D Shuttle Buggy® material transfer vehicle can store hot mix asphalt and transfer it from a truck to a paver for continuous paving. A patented antisegregation auger remixes materials just before they are delivered to the asphalt paver. The 25-ton (22.7 MT) surge capacity of the SB-2500D allows trucks to unload material immediately and return to the asphalt plant. Options include a windrow pickup head and road widener attachment.
CAT® C9-300 HP, Tier llI, 6-cylinder diesel engine, 300 HP (224 kw) @ 2,200 rpm. Engine instrumentation includes
tach/hour meter, oil pressure, voltage and emergency shutdown system. Easy access to oil cooler/radiator.
Operator positions on both sides. Control panel pivots for use from either station allowing for same-lane or adjacent-lane operation from either side. One-piece hydraulically-raisable hood allows easy access to engine, pumps and motors. Inside turning radius 26™6″ (8.1 m).
All hydrostatic for continuously variable speed control with two speed ranges. Electric-over-hydraulic shift between working and transport ranges. Maximum speed (working range) 3.0 mph (4.8 kph). Maximum speed (travel range) 9 mph (14.5 kph).
Large, high-flotation – 21:00 x 25″ (53.3 m x 635 mm).
Standard system includes heavy-duty alternator, battery, and circuit breaker protection of all systems.
