e-MIXER RX

e-MIXER RX

KYB e-Control Hydraulic Unit
Computerized control for optimized engine
rotation
The e-MIXER RX is the world’s
first concrete mixer to incorporate
a computer-controlled hydraulictransmission system, whichallows rapid drum rotation
without increasing engine speed.
This reduces fuel consumption over 10% compared withconventional concrete mixer trucks for wet concrete. Lowering
the engine speed also substantially reduces the noise level.
This innovative system won the 2007 Japan Machinery
Federation Chairman’s Award for Excellence in Energy
Efficiency and Conservation.
Compared to the standard type, the e-MIXER RX saves
approximately one liter of fuel per truckload.
Assumptions: Duration of drum rotation at high speed (Mixing:6 minutes; Mixing at construction site: 2 minutes;
Washing after delivery: 3 minutes; Washing after
return to truck yard: 3 minutes)

The e-MIXER RX saves approximately 720 liters of fuel annually.
Assumptions: (3 castings/day, 20 days/month, 12 months/year)

8A computer monitors the e-MIXER RX’s status to prevent accidental
concrete discharge. If the operator attempts to move the truck during
discharge, the drum’s rotation is automatically switched off, stopping
the concrete discharge.

Semi Auto-Clean Function for Drum

Outstanding Mixing and Durability
The e-MIXER RX uses unique mixer blades, designed
after many years of research. The blades can thoroughly
mix concrete without rotating at a high speed. Made ofrugged high-tensile-strength steel developed by a Japanese
steelmaker specifically for this application, using this steel
increases the drum’s working life. Furthermore, the design
minimizes the truck’s weight.

Manually input a certain amount of water and press a single button toautomatically rotate the drum clockwise and anticlockwise. (The number ofrotations and amount of water for cleaning can be set.)Auto-Mixing Function
At the delivery site, the operator can press one button to perform the predetermined mixing prior to discharge. The number of drum rotations androtating time can be set. (Timed operation is also possible for wet mixing.)

High Fuel Efficiency +Low Environmental Impact
KYB is Japan’s largest manufacturer of concrete mixers, with a market shareof more than 80%. Using its advanced technologies, KYB has developed anelectronically controlled model with a 7.5m3 drum.

Standard Equipment to Meetthe Requirements of Any Site
The e-MIXER RX comes with four
extension chutes, an aluminum rearladder, rear steps, digital slump monitor,
emergency stop button, water meter,and other standard equipment to meetthe requirements of almost any deliverysite.

New Easy-to-Use ControllerStandard equipment with a radio and wired
controllers for ease of use.
Button-Type Radio Controller
Single-Hand WiredController
Cab Controller ConsoleThe operator can select a
special mode for concrete
discharge while the vehicle
is moving. (A warning lightflashes during this mode toalert the driver.) In addition, abuzzer sounds while concrete
is discharging.
