A mobile scaffolding ( 10 ) for elevating a worker (not shown) above a floor or ground surface (S) is disclosed. The scaffolding ( 10 ) broadly includes a pair of frames ( 12 ) and ( 14 ), a platform ( 16 ) supported by the frames ( 12,14 ), a pair of casters ( 18, 20 ) and ( 22, 24 ) rollably supporting a respective one of the frames ( 12,14 ), and a brake assembly ( 26, 28, 30, and 32 ) associated with a corresponding one of the casters ( 18,20,22,24 ), respectively. The inventive brake assemblies ( 26,28,30,32 ) enable the worker supported on the platform ( 16 ) to selectively activate and deactivate the respective brake assemblies ( 26,28,30,32 ) from the platform ( 16 ). This enables the worker supported on the platform ( 16 ) to deactivate the brake assemblies ( 26,28,30,32 ), reposition the scaffolding ( 10 ), and then reactivate the brake assemblies ( 26,28,30,32 ) without requiring the worker to dismount from the platform ( 16 ).
