12" Gauge Cast Iron Dollies

 
Description:

Dollies designed with various styles and heights to accommodate plant requirments.

TYPE "S" Standard Dolly - Suitable for 6", 7", 8" and 9" laydown platforms.

TYPE "SL" Steel Dolly - Suitable for 6", 7", 8" and 9" higher laydown platforms.

TYPE "R" Rotary Top Dolly - Suitable for 7", 8" and 9" laydown platforms.

Maintenance:

Perdiodically check the 1/2" set screws located underneath axle support columns on the dolly base. Ensure that these set screws are neither loose nor missing. If so tighten or replace as needed.

The sole purpose for the 1/2" set screw is to absorb impact forces generated suring roll loading and dolly travel. With loose or missing set screws these forces will elongate the poured babbit axle supports causing loose axles creating premature wear on both wheels and imbedded track.

Check axles for tightness. If still using obsolete needle type bearings, remove wheels and bearings. Inspect axles for wear and galled. If either is present axles(s) will have to be replaced.

Check wheels for wear. (Refer to 7WH-1, 7WH-2) If wheels show any aigns of wear they must be replaced.

If using TYPE "R" (Rotary Top) dollies, inspect index lock pin for wear. If the lock pin shows any sign of wear it must be replaced. Faulty index lock pins will allow the dolly tops to free spin with loaded roll creating a potential accident.

 

12" Gauge Cast Iron Dollies Type "S" Dolly


Description:

 
TYPE "S" dolly consists of a single body casting, two axles secured in babbit with four set screws with removeable locktite adhesive.
 
The axles are fixed into place during manufacturing and are trued in all four axis to ensure proper height and precision alignment with the track.
 
Impact of loading is absorbed by the hardened set screws, thus protecting the softer babbit from compression.
 
Older dollies, utilizing the obsolete needle bearings, have greater chance of the bearing race galling the axle. When this occurs a total dolly rebuild at the factory is required. If the axles are symetrically sound, the wheels with dual sealed bearings can simply be replaced, saving a costly dolly rebuild.
 
Notes:

D) Radius of wheel and track should be mirrored, for proper contour fit, and to reduce wear.

K) 14" Center Line of axles.

 

 
 
 
 
12" Gauge Cast Iron Dollies Type "SL" Dolly

 
Description:
 
TYPE "SL" dolly is typically custom fabricated using quality structural steel to accommodate unique plant requirements. I.E. high laydown area.
 
TYPE "SL" dolly consists of a single fabricated steel body with two welded axles.

Notes:

D) Radius of wheel and track should be mirrored, for proper contour fit, and to reduce wear.

K) 14" Center Line of axles.

 

 
 
 
 
 
 
 
 
 
 
 
 
 
12" Gauge Cast Iron Dollies Type "R" Dolly

 
Description:
 
TYPE "R" dolly consists of a two piece dolly body casting, two axles secured in babbit with four set screws with removeable locktite adhesive and one spring loaded foot operated lock mechanism.
 
The unique feature about the "R" dolly is by depressing the foot operated lock mechanism reel room operators can freely rotate the dolly top allowing rolls to be indexed without having a turntable based track system.
 
The axles are fixed into place during manufacturing and are trued in all four axis to ensure proper height and precision aliginment with the track.
 
Impact of loading is absorbed by the hardened set screws, thus protecting the softer babbit from compression.
Older dollies, utilizing the obsolete needle bearings, have greater chance of the bearing race galling the axle. When this occurs a total dolly rebuild at the factory is required.

K) 14" Center Line of axles.

M) Rotary top dolly index lock pin.
