26 PNEG-707 12', 18', 24' and 30' GSI Commercial Tower Dryer
Pre-assembly
This construction manual provides directions for installation of parts starting at the top section of the dryer
and building down. Some installations can be done simultaneously, and some can be pre-assembled.
The following installations can be pre-assembled on the ground before installing them to the dryer.
1. Interior and exterior walkway sections. (Catwalk and platform.)
2. May need to pre-assemble reducer housing.
3. May need to pre-assemble burner housing.
4. Bolt a splice to each channel before installing it to the preceding channel.
5. Top safety cage can be pre-assembled on the ground before installing it to the dryer.
It is recommended that the remaining ladder and safety cage sections not be pre-assembled. Install
them directly to the dryer.
Ladder Installation
1. Roof access port, bindicator(s), and grain temperature sensors must be accessible from outside
tower ladder.
2. Install outside ladder one (1) bolt hole to the left of a vertical channel. Install outside ladder so it will
terminate with clearance from dryer legs.
Layout and Clearance
Plan ahead to locate tower dryer for the convenience of the dryer operator, and in correct orientation to
existing equipment and structures.
Consider the following when planning dryer layout.
1. Dryer orientation cannot be rotated after start of construction.
2. Determine where utilities will come into dryer. Locate dryer electric and fuel intake accordingly.
3. Plan dryer leg placement so that when dryer is complete, grain unload conveyor is centered
between two (2) dryer legs.
4. Landings (catwalks and platforms) are 42" wider than the perimeter (wall) of the dryer. Plan an
additional 42" for lateral clearance from existing equipment and structures. Total lateral clearance
radius with landings is 12'-8" from center of dryer.
5. Estimate finished dryer height and check for overhead clearance from electrical power lines,
equipment and structures.
6. Follow wall sheet assembly diagram for ladder, platforms, door, windows and sensor placement.
However, these components can be relocated to some degree for convenience.
