Wheel and casters configuration

 

Three swivel castors of the same height

 
 
This option is used for light loads and provides the ability to move in all directions. The disadvantages are the limited stability of the rectilinear movement and the tendency to capsize.
 
 
 

Four swivel castors of the same height

 
 
This option is used in the presence of narrow passages, as provides good maneuverability in all directions. The disadvantage of this solution is the limited stability of the rectilinear motion.
 
 
 

Two swivel and two fixed castors of the same height

 
 
The most commonly used solution. Provides stability as a rectilinear motion, and movement along a curve. The disadvantage is limited maneuverability in narrow aisles. Alternatively, it is possible to replace both fixed rollers with a pair of wheels (two wheels on one axle).
 
 
 

Four fixed rollers, of which medium two are higher rollers

 
 
Inexpensive solution. Provides high stability of rectilinear movement with relatively easy control. The disadvantage is the tendency to capsize. Alternatively, medium fixed rollers can be replaced with a pair of wheels (two wheels on the same axle).
 
 
 

Two swivel and two fixed castors, of which fixed are of higher height

 
 
Provides high stability of rectilinear movement and the possibility of a turn in place. Due to the possibility of tipping over, it is recommended to use it on even floor surfaces. Alternatively, it is possible to replace both fixed rollers with a pair of wheels (two wheels on one axle).
 
 
 

Four swivel and two fixed castors of the same height

 
 
An expensive solution. Recommended when transporting heavy loads on long platforms. Easy to manage. Alternatively, it is possible to replace both fixed rollers with a pair of wheels (two wheels on one axle).
