Operating the Powered Mast
NOTE: Numbers in parentheses () correspond to item numbers in the
Powered Mast Subassembly
bill of materials on p. 11.
Units equipped with the powered mast option (-PMO) use an electric
motor and gearbox (5) to raise and lower the stretch wrap carriage.
The motor and gearbox interface with a chain-and-sprocket drive
system (12 and 4). The chain forms a loop through the mast (2). It
attaches to both the top and bottom of the stretch wrap carriage (1).
When the sprocket turns clockwise, the chain is pulled up the mast,
which causes the carriage to rise. The carriage descends when the
sprocket turns counterclockwise. A 2-button, handheld controller allows
the operator to select the direction the carriage travels, i.e. UP or
DOWN. The carriage only moves while a button is pressed and will
maintain position when the button is released. Limit switches (item 22
on p. 11) at the top and bottom of the mast prevent the carriage from
being raised, or lowered, too far.
Use the handheld controller to change position of the stretch wrap as necessary while wrapping an
item.
