Plan The Mainframe Unload
Unloading the main frame can be a safe, smooth
operation if it is properly planned in advance.
▲ Scope the lift equipment and team size required.
▲ Review the steps with all lift team members.
▲ For multiple lifters, gather lifters and practice simultaneous
lift. Learn control operations for equal lift rates.
▲ Designate an observer to be lift leader.
▲ Have an agreed signalling or command for simultaneous
halting of the lift if any team member detects a problem.
▲ Move the trailer, not the planter.
Use a Hoist or One to Four Lifters
Use lifter(s) with a combined capacity greater than the
weight of the planter main frame.
Do not use more than 4 lifters. There are no safe rear lift
points for more than one lifter.
When using N (2 to 4) lifters, do not assume that each is
getting
1 ⁄
N
th of the load. Plan excess capacity. Monitor
load indicators and overload indications or alarms.
Location Requirements
Until assembled, the planter mainframe is impractical to
move. It needs to be unloaded directly above the spot
where final assembly takes place.
This location needs to be:
• firm level ground or pavement -
the parking stand loads can approach 100 psi
• there must be adequate space to pull the trailer out
from under the lifted mainframe, without turns,
• there must be adequate open space behind the
mainframe to attach the seed substructure,
• there must be adequate space all around to easily
maneuver fork lifts on both sides, and later behind the
seed frame, and
• there must be adequate space in front of the planter to
attach a tractor and move forward for delivery.
Mark the parking location with traffic cones or pavement
markers.
Note: Unless it is certain that the assembled planter will
only be moved with the tractor on which the
steering sensor is installed, allow ample room in
front of the planter, so that non-sensor tractors
need only make forward moves.
