Examples of Transport Dolly Configurations
#1 3-Point Support System for Standard Applications
Recommended Configuration!
Employed Dollies: (Position B) Steerable transport dolly
(Positions G & I) Straight-line transport dolly
Consideration: Weight is equally divided across all 3 contact points. Load cannot rock on even or uneven ground. Dollies will stay in place even under pulling and tugging action.
(Assumption: Center of Gravity in middle).
#2 3-Point Support Configuration with Shorter Turning Radius
Employed Dollies: (Position B) Steerable transport dolly
(Positions D & F) Straight-line transport dolly
Consideration: The straight-line dollies will carry 70% of the weight, while the steerable dolly is used for support only. The advantage: The turning radius is dramatically reduced.
For the steerable dolly not to slip out from the pulling force, the steerable dolly is required to carry at least 25% of the load weight.
To utilize system, straight-line dollies must have a higher capacity than with a standard system.
#3 4-Point Support System for Loads on Legs or on C-Channels
For Special Application Only!
Employed Dollies: (Positions A & C) Steerable transport dolly
Positions (G & I) Straight-line transport dolly
Consideration: Use only if 3-point support is not possible, for loads with legs or C-channel.
Load can rock when travelling over uneven surface resulting in: (1) A shift of weight, (2) loss of contact with one dolly, (3) possibly overloading other dolly, and (4) slipping of dolly out from underneath.
#4 Configuration for Added Maneuverability on the Back End
For Special Application Only!
Employed Dollies: (All Positions) Steerable transport dollies
Consideration: Configuration provides added maneuverability on front and back end for movement around tight corners.
Not recommended for loads over 10 tons due to need for forklift assisted steering on both ends as front and back end travel in separate directions.
#5 Rotating Dollies with Steerable Transport Dollies for Short Radius Turns
Mix and Match!
Employed Dollies: (Position B) Steerable transport dolly
(Positions G & I) Rotating dollies
Consideration: Ideal for short radius turns - Steer or tow around corner and swing the backend around for short turning radius.
#6 Configuration for Loads That Sag in the Center
For Special Application Only!
Employed Dollies: (Position B) Steerable transport dolly
(Positions D & F) Rotating dollies
(Positions G & I) Straight-line transport dolly
Consideration: Steerable system, with rotating dollies that will support the load from sagging in the center.
If the load is able to rock on uneven ground like a seesaw, center dollies will carry all the weight and may get overloaded. Please use large safety capacity for center dollies accordingly.
#7 Configuration for loads that sag in the center
For Special Application Only!
Employed Dollies: (Positions B & H) Steerable transport dolly
(Positions D & F) Straight-line transport dolly
Consideration: Configuration provides complete maneuverability.
If the load is able to rock on uneven ground like a see-saw, center dollies will carry all the weight and may get overloaded. Please use large safety capacity for center dollies accordingly.
#8 Configuration for straight-line transport
For Special Application Only!
Employed Dollies: (All Positions) Straight-line transport dolly
Consideration: For straight-line transport only.
Aligning front and back rollers in same direction is difficult. Roller material may wear down over time from misalignment.
