R2S-S LASER RECEIVER. Detects the laser beam and sends correction signals to the Remote
Interface Box. Corrections are then sent to raise/lower the grader blade.
EM2E-24 ELECTRIC MAST. This is a telescoping mast for the R2S-S Laser Receiver, and is
mounted to the top edge of the blade. The EM2E-24 Electric Mast, with the R2S-S Laser Receiver,
electronically measures vertical movement and sends signals to the Remote Interface Box for
MAST RISER. Attaches between the mast mount and the shock mount. Adds to the overall height
of the mast assembly to ensure the R2S-S Laser Receiver's height over the cab can be obtained.
MAST MOUNT. Used to connect the mast assembly to the machine blade. The unit is adjustable so
that the EM2E-24 Electric Mast can be put in plumb position if the blade is rolled.
SHOCK MOUNT. Attaches to the EM2E-24 Electric Mast as part of the mast assembly. Protects
the EM2E-24 Electric Mast and the R2S-S Laser Receiver from vibration.
