Many factors determine the choice of a wheel
WORKING CONDITION
The weight to carry, the intense utilization of full or average load, frequency utilization of the cart, type of utilization (manual traction or with motorized engines)
NATURE OF SURFACE
Plain, rough or very uneven.
PARTICULAR REQUIREMENT
Utilization in corrosive atmosphere or in an oxidizing environment, hygienic norm to be respected, temperature usage.
EXPLOITATION CRITERIA
Smooth rolling, non-marking tread, requires little physical force.
HOW TO DETERMINE YOUR UNIT LOAD IN ALL SECURITY
You have a cart equipped with 4 casters:
We suggest dividing by 3 the total load (do not forget that on irregular surface the weight can momentarily be spread on 3 points instead of 4). However, the load capacities indicated in our catalogue takes in consideration a maximum safety margin for a manual movement of 1.9 mile/hour (3km/hour).
HOW TO SELECT YOUR BEARING TYPE
|
BALL BEARING : |
DELRIN® : |
|
Continuous or intensive usage on maximum loads. |
Usage in presence of corrosive substance. |
|
STANDARD ROLLER BEARING: |
PLAIN BORE : |
|
Intensive usage on average load. |
Intermittent usage (economical) |
PATTERN POSIBILITIES UNDER CARTS
|
Very easy maneuver 4 swivel castors. May be hard to steer over long distances or on uneven ground |
 |
Long distances with infrequent changes of direction 4 fixed castors, the 2 central ones being raised. (Economical) |
|
|
Maneuver in restricted spaces 2 swivel castors, 2 fixed castors. Precise steering |
 |
Long and varied distances (regular pattern) 2 swivel castors, 2 fixed castors. Precise steering |
|
|
Handling heavy loads and for very long carts 4 swivel castors, 2 fixed castors. Very stable. Easy to handle |
 |
Small loads 3 swivel castors. Very easy to handle. Difficult to steer in a straight line, precarious balance. |
