How to Select Castors and Wheels
To identify the castor and wheel best suited to your needs, simply answer these six questions:
| Question 1: Which category most closely matches the intended use? |
| |
Some Typical uses |
Max.Load kg/castor |
| Super |
Maintenance platforms and trolleys, cargo trolleys, mobile lifting equipment |
2000 - 10,000 |
| Heavy Industrial |
Heavy duty trolleys, heavier mobile equipment, waste bins |
250 - 2000 |
| Industrial |
Heavy bakery trolleys, engine stands, heavy laundry trolleys, lighter trolleys used frequently or outdoors |
110 - 700 |
| Towing |
Equipment moved at speeds exceeding 5km/h |
80 - 10,000 |
| Scaffold |
Scaffold equipment |
225 - 1,000 |
| Medium Industrial |
Medium trolleys, bakery oven racks, larger display stands, laundry trolleys, equipment racks |
45 - 400 |
| Commercial |
Medium/light trolleys, display stands, heavier furniture, tool boxes |
15 - 205 |
| Institutional |
Hospital beds and furniture, office quipment, serving trolleys, computer equipment and display stands |
75 - 125 |
| Furniture |
Light furniture, chairs, light display stands |
30 - 50 |
| Question 3: What load must each castor carry? |
Under ideal conditions the load is equally shared by all castors.
However, for uneven floors use the actual number of castors less one for calculation purposes. |
| |
| Example: |
Max Load + Weight of Trolley
No. of Castors - 1 |
| Load per castor = |
402 + 105
4 - 1 |
= 525 =
3 |
175 kg |
|
| Max Load: |
420 kg |
| Trolley: |
105 kg |

| Question 4: How big should the wheels be? |
| The larger the wheel, the easier it rolls |

Long Towing |
Irregular large obstructions |
Note: In situations where equipment operating space is limited, for example where there is a low overhead clearnance, the overall height and swivel radius of the castor will become important selection criteria.
Note: Wider wheels are harder to push but can carry heavier loads. |
| Question 5: To what will the castors be attached? |
| There are 2 types of castor frame. |
| Plate mounted |
Attaches directly to the underside of your trolley via a number of fixing bolts.
Available in both fixed and swivel types. |
| Bolt Hole |
Allows mounting with a single bolt or fitting to round or square tubing with optional pintles. |
| Note: The overall durabiltiy of the castor frame depends largely on its construction. See table |

| Question 6: Do the castors need brakes? |
| Brake mechanisms can be added to most Lemcol Castors. |
| Type |
Code |
Description |
| Wheel Brake |
B or H |
