Castor wheels and material handling trolleys are among the most under-specified items in Northeast Indian factories and workshops — and the most common cause of musculoskeletal injuries and floor damage. This guide gives you a systematic method for specifying the right castor type, load rating, wheel material and trolley configuration for your facility.
Written by the counter team at Multi Trade Combines — 35 years supplying NE workshops.
From Guwahati's food-processing plants on the Brahmaputra plains to the hill-terrain garment factories of Shillong and the tea-garden machinery sheds of Dibrugarh and Jorhat, floor conditions vary enormously. A castor specified for a smooth Mumbai warehouse floor will chip and seize on the rough aggregate concrete of a Guwahati fabrication yard. Getting the floor assessment right before ordering is the single most important step.
Choose your configuration based on how the trolley will actually move in your facility.
| Castor type | Description and best use |
|---|---|
| Swivel castor | Rotates 360°; best for tight-space manoeuvring in workshops and warehouses. |
| Fixed castor | Straight-line only; used in combination with swivel castors for directional stability on long runs. |
| Swivel with brake | 360° rotation plus a foot-operated locking brake; recommended for workshop trolleys on slopes or uneven floors. |
| Rigid directional | Fixed axis; used on conveyor dock trolleys and heavy straight-line pallet movers. |
| Recommended config. (workshop) | 2 swivel with brake (rear) + 2 swivel (front) — best balance of manoeuvrability and safety. |
Match the wheel material to your floor surface and the chemicals present.
| Wheel material | Load, floor type, and notes |
|---|---|
| Cast iron | Very heavy loads; rough concrete and outdoor use; low shock absorption; rusts in wet conditions. |
| Polyurethane (PU) | Medium to heavy loads; smooth concrete and tile floors; high shock absorption; oil-resistant; does not mark floors. |
| Rubber | Light to medium loads; all smooth floors; very high shock absorption; swells in oil contact; may mark floors. |
| Nylon | Medium loads; smooth dry floors; low shock absorption; excellent chemical resistance; does not mark floors. |
| Steel / phenolic | Heavy loads; rough or outdoor surfaces; low shock absorption; rusts in humid NE conditions — avoid wet environments. |
The most common mistake when buying castors is underrating for dynamic load. Static load (trolley parked) is always higher than a castor's continuous dynamic load rating. Follow these steps:
Example: A tea-estate machinery trolley carrying 800 kg on rough concrete with 4 castors needs: 800 ÷ 4 × 2.0 = 400 kg per castor. Specify 500 kg rated castors for safety margin.
Beyond individual castors, the trolley frame and deck material matters:
Northeast India presents three conditions most standard castor specs do not account for:
Multi Trade Combines stocks platform trolleys, wheel barrows and industrial castor wheels at our AT Road, Guwahati counter. We can help you specify load ratings and configurations — bring your floor photos and load requirements and our counter team will size the right unit in minutes.
Divide the total trolley load (including the trolley frame itself) by the number of castors, then multiply by a safety factor of 1.3–1.5. So a 500 kg load on a 4-castor trolley needs castors rated at minimum 500/4 × 1.5 = 187.5 kg each — round up to 200 kg rated castors. For dynamic loads (bumps, ramps), increase the safety factor to 2.
For wet or chemically exposed floors, choose stainless steel housing with polyurethane (PU) or rubber wheel material. PU castors resist oil and mild chemicals, cushion vibration and do not mark floors. Avoid cast-iron wheels on wet floors — they rust and can crack on cold concrete. Rubber wheels absorb shock but swell in oil contact.
