The invention discloses a double-brake control trundle which comprises a trundle body, the trundle body comprises a trundle frame and a rolling wheel, the rolling wheel is rotatably connected to the trundle frame, a brake assembly is arranged on the trundle frame, and the brake assembly comprises a first rotating part, a second rotating part and a third rotating part. The first rotating part, the second rotating part and the third rotating part are all rotationally connected to the wheel frame, a first treading part is arranged at one end of the first rotating part, the other end of the first rotating part can abut against a limiting block on the second rotating part, the second rotating part is located below the first rotating part, and a braking part is arranged at the end, away from the limiting block, of the second rotating part. The brake part can abut against the rolling wheel, a jacking part is arranged at one end of the third rotating part, a second treading part is arranged at the other end of the third rotating part, and when the first treading part is treaded, the first rotating part abuts against the rolling wheel. Compared with the prior art, the caster brake assembly can solve the problem that an existing caster brake assembly is unstable in roller fixing.
