Using industry trip and distance averages, SMART Drum extends the life of the drum by more than 80-percent! A standard feature is cumulative monitoring of total drum revolutions for management purposes.
Deliver Quality Concrete
A constant drum speed yields a more consistent concrete mix. Over mixing damages the quality of the concrete by increasing the temperature of the mix, lowering the slump, decreasing air entrainment and decreasing the strength of the concrete.
Improve Fuel Efficiency
Fewer drum rotations means less horsepower draw and better fuel economy.
A constant drum speed maintains the center of gravity with a loaded truck for better stability in corners.

SMART DRUM OVERVIEW
Gain control of drum rpm with the new SMART Drum option from Schwing-Stetter. The benefits of a constant speed drum are combined with an innovative control system to optimize drum rpm…automatically. No need to monitor or remind drivers to set a constant speed – SMART Drum does it for you by making drum rpm independent of engine rpm. When your driver accelerates past threshold speed, SMART Drum takes over and the drum speed is held constant. The result is less horsepower draw, less wear and fuel savings from fewer drum rotations. See how SMART Drum from Schwing-Stetter improves your bottom line every day by saving up to 80% in drum wear.
More Stable Operation
Customers report more stable operation due to constant drum speed. By avoiding changes in drum speed due to down shifting in turns, the potential for roll-overs is diminished. See a ready-mix producer’s comments about SMART Drum in our Truck Mixer product reviews.

SCHWING MIXER TECHNOLOGY
Head 1/4” high chromium abrasion-resistant steel Shell 3/16” high chromium abrasion-resistant steel Shape Low profile for fast charging, mixing & discharging Blades 1/4” thick abrasion-resistant steel. Reversed lip mixing blades for optimum mixing
Forged Steel wide roller track to lower stress between drum roller and track.
Two stage 7000 series ZF drive gear box with a deep reduction drive.
Bolted in place 19” x 24.” Located in the front section of the drum. Additional hatch available (Consult Factory).
New ladder design folds down and angles out for easier ascent by drivers. Water plumbed to wash station and at ground level with diversion valve.
Swing Chutes – Four Foot Chute
5’6” chute with 3’2” foldover and one 4 foot chute side frame mounted. Optional liners and additional 4 foot chutes are available. Engine driven chute hoist with controls at mixer rear and in cab. Storage for up to three 4 foot chutes in cradle or gun rack.
Surface hardened 8-inch diameter alloy steel with tapered Timken™ roller bearings with center shaft lubrication. Remote central greasing standard.
Charging Hopper 44.5″ x 28.5″ opening with 30″ throat for smooth charging. Optional flip up hopper available.(Booster)
New 20% larger design for easier clean-up and better flow with 45 degree drop angle.

The durable remote control system allows drivers to start and stop the drum, switch from discharge to charge, throttle up or down, lock or unlock and rotate the chute. Remote is equipped with a powerful magnet for attachment to virtually any part of the truck mixer. The transmitter hops frequencies for a strong signal without interference from competing signals. Mounts in cab for charging next to LED display for instant status and control of drum stop/start, chute lock, throttle up/down, tilt hopper, work lights and up/down/stop and pressure of the booster axle. The system also stores drum speed history and revolutions. An error message displays codes for trouble-shooting.
Rear pendant control is optional equipped with a 25’ mobile hard wire control.
Full width smooth top steel or aluminum. Extra strong fenders with center bracing for extra support. Each fender has recessed stop, turn and tail lights. Rear mudflaps are standard. Optional front mud flaps available.

Mounted each side with two positions. One rigid mount and one with a spring connection. Front pedestal is made from high strength steel.
“After talking to Schwing, we realized our roll-overs were probably preventable. Since we added SMART Drums four years ago, we haven’t had any roll-overs.” Joey Ditta, Carlo Ditta Ready-Mix Concrete, Harvey, LA
