Heavy-duty 200 mm red polyurethane plate castor — for trolleys and material-handling platforms carrying loads up to 400 kg per wheel in industrial settings.
The Envoy 8" x 2" Red PU Plate Castor is a heavy-duty swivelling wheel assembly with a 200 mm diameter polyurethane-treaded wheel, 50 mm wheel width, and a 200 × 50 mm top plate for bolting onto trolley frames, equipment bases, and material-handling platforms. At 200 mm diameter it is the largest standard plate castor in the Envoy range, designed for the heaviest wheeled platforms in industrial and warehouse environments. The red polyurethane tread protects sealed concrete and epoxy-coated industrial floors from damage, rolls quietly, and resists oil and mild chemical contamination.
Multi Trade Combines stocks the Envoy castor range — from the compact 75 mm stem-mount to the 200 mm heavy-duty plate castor — at our Guwahati counter. Customers across Assam's manufacturing and warehousing sector, from rice mills in Barpeta to plywood plants in Dimapur and steel fabrication yards in Guwahati, use Envoy plate castors for trolleys and material-handling platforms that move heavy loads daily.
Steel and metal fabrication yards use large plate castors on tray trolleys and component-moving platforms that carry structural steel sections, plate offcuts, and heavy sub-assemblies between workstations. The 200 mm wheel rolls over shop-floor debris, welding spatter, and minor floor cracks without the castor jamming or the load tilting.
Warehouse and logistics operations in Guwahati's growing distribution sector use heavy castors on large picking trolleys, packing carts, and transfer platforms. A 200 mm wheel carries heavy pallet-equivalent loads (drums, machinery parts, bagged goods) without the rolling resistance problems of small wheels on heavy loads — a 100 mm castor under 400 kg takes significant push effort; a 200 mm castor under the same load rolls with noticeably less effort.
Tea factories use heavy-duty castors on withering-trough trolleys, CTC machine maintenance platforms, and bulk-tea storage bins that are moved within the factory between shifts. The PU tread is particularly valued in tea factories where rubber-tread castors leave black marks on the factory floor that contaminate the tea.
This castor pairs with the Envoy 8" plate brake castor to provide a two-brake, two-plain configuration on heavy trolleys — standard practice for trolleys that will be parked on inclined factory floors or near machinery where unattended movement is a hazard.

An 8-inch (200 mm) polyurethane castor typically carries 250–400 kg per wheel, depending on the bearing grade and swivel head design. A heavy-duty trolley fitted with four such castors has a total load capacity of 1,000–1,600 kg — suitable for moving steel coils, heavy machinery components, large pallet loads, and industrial drums. At 200 mm diameter, the castor also clears floor obstructions (cable runs, door thresholds, minor surface irregularities) that a smaller 100 mm castor would struggle with, making it the right choice for platforms and material handling in factory areas where floor uniformity is not perfect.
The 200 × 50 mm plate (8 inch x 2 inch) has four corner bolt holes for bolting the castor to the trolley frame or equipment base. This plate-mount design gives a rigid, secure fit and is the standard for heavy-duty trolley construction in industrial settings. Ensure the trolley frame steel at the mounting point is thick enough to take the bolt load under maximum castor load — 5–6 mm mild steel plate is typically adequate for 400 kg per castor. If bolt access is limited on an existing trolley, stub-axle stem-mount castors may be more practical for retrofitting.
