Bracket Design for Heavy Duty Casters
Heavy-duty casters commonly utilize metal materials for their brackets, which are typically constructed using various methods such as ordinary steel plate stamping, cast steel forming, and die forging steel forming. These brackets are often assembled using flat plates. The thickness of steel plates in heavy-duty casters typically ranges from 8mm to over 20mm, with common measurements being 8mm, 10mm, 16mm, and even thicker. To ensure the utmost safety of the loaded products, Wanda has designed 12-ton heavy-duty casters for CNPC that feature 30mm thick steel plates and 40mm pallets. This robust construction guarantees the security and stability of the products being transported.
Rotating plate design for heavy duty casters
Double-layer steel ball tracks, stamping, and heat treatment are commonly used in the construction of heavy-duty casters. The rotating plate of an extra-heavy caster typically utilizes plane ball bearings or plane needle bearings that can withstand greater force. These bearings are often paired with conical bearings to enhance the load capacity of the caster. In the case of specialized impact-resistant heavy-duty universal wheels, the rotating plate is made from die-forged steel. This manufacturing process ensures a finished and formed product, eliminating the need for welding connecting plate bolts. As a result, the caster gains increased strength and improved resistance against impact.
