Envoy EN-5 heavy-duty castor clamp — 10 mm fabricated mild steel housing for industrial trolleys and heavy material handling carts in workshops and factories.
The Envoy EN-5 is a heavy-duty castor housing fabricated from 10 mm mild steel plate, designed for industrial trolleys, material transfer carts, and heavy-duty platform trucks operating in workshops, factories, and warehouses. Unlike pressed-steel light-duty castor housings, the EN-5 is cut and welded from thick plate, giving it significantly greater resistance to bending and deformation under heavy loads and impact. The clamp is designed to accept standard castor wheels of various tyre materials — rubber, polyurethane, or nylon — making it a versatile base for custom trolley builds and industrial cart fabrication.
Multi Trade Combines stocks Envoy castors and clamps in Guwahati alongside our complete range of castors and trolleys. The EN-5 heavy clamp is particularly popular with engineering workshops and fabrication units building custom industrial trolleys for tea factory material handling, machine shops moving heavy components between machines, and construction sites moving bundles of rebar, formwork panels, and scaffolding equipment within the site compound.
Industrial trolley fabricators and maintenance workshops are the primary buyers of the EN-5 clamp. A small-scale trolley fabricator making workshop carts and platform trucks for factories in Guwahati's Beltola and Amingaon industrial areas specifies the EN-5 for any trolley designed to carry over 400 kg per unit. The 10 mm plate construction ensures the housing does not bend or crack from repeated heavy loading and the impact of loaded trolleys being pushed over floor joints and threshold lips.
Tea estate engineering teams in Upper Assam build heavy trolleys for moving withering troughs, tea chest stacks, and processing machinery components within the factory. They specify fabricated housings rather than pressed-steel castors because the factory floor environments — wet, sometimes uneven, and exposed to tea oil and moisture — can corrode lighter castors rapidly. The 10 mm M.S. construction of the EN-5 can be repainted or galvanised for extra corrosion resistance.
The EN-5 pairs with Techmo rubber and polyurethane wheels from our castors and trolleys range to create a complete heavy castor assembly. Combined with a welded steel platform, the result is a fully capable heavy industrial trolley built for Northeast India's demanding factory conditions.

The Envoy EN-5 heavy clamp uses a fabricated 10 mm mild steel plate mounting bracket designed with adjustable bolt-hole spacing or a universal mounting plate that accommodates the pin-bolt patterns of most standard castor wheels (rubber, PU, and nylon) in the 50–200 mm diameter range. This means you can mount a variety of wheel types on the same EN-5 clamp body without needing a different housing for each wheel type — particularly useful in operations where wheel types need to be swapped for different floor conditions or load requirements.
The load capacity of a castor clamp depends on the structural rating of both the clamp housing and the wheel. The Envoy EN-5, fabricated from 10 mm mild steel plate, is designed for industrial trolley duty — carrying loads significantly heavier than light-duty pressed-steel castors. Exact rated capacity depends on the wheel and bearing combination installed. For heavy workshop trolleys, pallet movers, and industrial carts typically carrying 300–1000 kg (total trolley load on 4 castors), the EN-5 fabricated clamp is the appropriate specification.
