Technical information
5. Set the ‘PICK/DROP’ switch to the center position
6. Turn on the computer
7. Turn on the System Power
8. Select machine side ‘LEFT’ or ‘RIGHT’
9. If placing cones, select distance ’25, 50, or 100’ and then choose ‘DROP’
10. If retrieving cones, select ‘FORWARD’ or ‘REVERSE’ and the ‘PICK’

12. Set machine side to ‘OFF’
13. Once the drop box is fully retracted, turn off system power
14. Turn off computer
1.4.2 Dropping Cones
The operator should anticipate where the first cone is to be dropped and start several feet
before. Once the ‘DROP/PICK’ switch is placed in the drop mode, the system will
initialize, grab the first cone, and then release it to be placed. When the cone is traveling
on the lateral conveyor, the operator should start accelerating the truck forward. To
insure even spacing the ACM should be driven at a constant speed. In general the speed
of the truck should be as follows.
1. 3-5 MPH for a 25’ spacing
2. 5-7 MPH for a 50’ spacing
3. <18 MPH for a 100’ spacing
The operator can choose to set an extra, or intermediate, cone by moving the
‘DROP/PICK’ switch to the center position and then back to the ‘DROP’ position.
1.4.3 Picking Cones
There are two items to pay close attention to when retrieving cones, the orientation of the
cone entering the primary funnel and the position of the cone retrieval arm. The primary
funnels are used to knock the cone over and to orientate the cone with the square base end
facing the drop box. If a cone is already knocked over with the square base facing the
drop box, the ‘GATE’ button should be pushed just prior to the contact of the cone with
the primary funnel. Pushing the ‘GATE’ button allows the paddle on the primary funnel
to float permitting the cone base to pass through the funnel. If the cone is knocked over
but not in the right orientation, the paddle is used to stand the cone upright such that the
primary funnel can turn it over and orientate it properly.
The cone retrieval arm grabs the cones from the secondary funnel and places them on the
lateral conveyor. The vehicle speed should be adjusted to allow sufficient time for the
arm to finish placing the cone on the lateral conveyor and return to the secondary funnel.
Failure to provide sufficient time will result in a cone being trapped under the retrieval
arm. If a cone is trapped under the cone retrieval arm, the ‘PICK’ switch should be
moved to the center position hence, raising the retrieval arm and primary funnel. Then
the truck should be driven a short distance in the opposite direction and the pick mode
resumed.
