A support trolley comprises a central leg pillar and at least three legs radiating therefrom, each supported at its outer end by a respective castor wheel assembly. The inner end of each leg joins the lower end of the leg pillar by a sliding engagement of complementary splined surfaces, so that assembly or disassembly is easily effected. The outer end of each leg has a downwardly facing recess which receives the upwardly directed pintle of a respective castor wheel assembly, that pintle being tubular and of resilient material.
