Heavy Duty Castors – Fabricated<\/b> Castors<\/b><\/h2>\n

Heavy Duty Castors & Fabricated Castors<\/strong><\/h3>\n

Heavy Duty Castors are manufactured for the most demanding and heavy weight applications, ensuring high performance and longevity are achieved under the most harshest of conditions. Applications using Heavy Duty Castors typically weigh between 5 Tonne to 30 Tonne.<\/strong><\/em><\/p>\n

Fabricated Castor Fork<\/strong><\/h3>\n

One of the primary differences between Standard Industrial Castors<\/a><\/strong> and Heavy Duty Castors<\/strong><\/a> & Fabricated Castors<\/strong> is the manufacturing method used to\"Fabricated
\nproduce the Castor fork.  Standard Industrial Castors<\/strong> are assembled with a pressed steel fork, where the primary part of the bracket is one metal piece manufactured from a “metal pressing” process. Metal pressing is a low cost manufacturing process that is used widely by Castor
\nWheel manufacturers<\/strong>, and is suitable for all but the most demanding applications.  On the other hand, a Fabricated Castor bracket<\/strong> is built (fabricated) using flat steel plate with a much increased steel gauge thickness.  The thick steel plate is cut into sections which are welded together to produce an extremely robust castor fork suitable both high loads and accommodating shock forces.<\/p>\n

Heavy Duty Castor Wheels<\/strong><\/h3>\n

It goes without saying that Heavy Duty Castors<\/strong> require Heavy Duty Wheels<\/strong> in addition to the Fabricated Fork.<\/p>\n

One of the most common Extra Heavy Duty Castor Wheels<\/strong><\/a> is a cast aluminium wheel hub, with a thin layer of polyurethane  tread.  The aluminium provides extremely good loading capacity, whilst the complimentary polyurethane tread provides compliance on hard flooring surfaces, shocks and bumps, in addition to reducing the noise of the wheel during manoeuvring.<\/p>\n

Other common Extra Heavy Duty Castor Wheels<\/strong> include Nylon Castor Wheels<\/strong><\/a>, Solid Polyurethane Caster Wheels<\/strong> and Cast Iron Wheels<\/strong>.<\/p>\n

It is common practice that the Extra Heavy Duty Wheels<\/strong> are manufactured with an increased wheel width, as this increases the size of the wheel, hence its strength but also increases the contact area with the floor, allowing for higher load.<\/p>\n

 <\/b><\/p>\n

Heavy Duty Castor Wheels -Bearings<\/strong><\/h3>\n

Due to the heavy weight that Extra Heavy Duty Castors<\/strong> can carry, the inertia forces that are required to move a heavy piece of equipment are normally very high, resulting in a high roll resistance. This difficulty is increased further due to the increase wheel width as discussed above.  It is therefore important that wheel bearings<\/strong> are used within the Castors wheel<\/strong> to reduce the roll resistance as much as possible.  However due to the heavy weights that castors<\/strong> may need to carry certain bearing types may be less suited.  Therefore the Castor Wheel<\/strong> supplier of bearing supplier should be consulted about the best bearing type for the weight and forces. These may include Ball Bearings<\/strong>, Roller Bearings<\/strong> and Tapered Bearings<\/strong>. Bulldog <\/strong>Range of Extra Heavy Duty Castors are manufactured which European specification Bearings to ensure high load and impact resistance of achieved.<\/p>\n
