The bracket of heavy casters usually adopts metal materials as the main body, including ordinary steel plate stamping, cast steel forming, die forging steel forming and so on. , usually assembled by flat plate. The steel plate thickness of heavy casters is generally above 8mm, 10mm, 16mm and 20 mm. At present, the super-heavy casters designed by Wanda for China petroleum system with the bearing capacity of 12 tons adopt 30mm thick steel plates with 40mm pallets, which effectively ensures the safety of loaded products.
Design of heavy universal wheel turntable
Heavy casters usually adopt double-layer steel ball track, stamping and heat treatment. For the turntable of super-heavy universal wheel, plane ball bearing or plane needle bearing with large stress is generally used, and conical bearing is matched, which effectively improves the bearing capacity of heavy caster. Special impact-resistant heavy universal wheel, the rotating plate is made of die forged steel, which effectively avoids the welding of connecting plate bolts and improves the impact resistance of casters with greater strength.
