A trolley comprising: a frame 20 comprising a base 25, the base forming a support with four corners and a wheel 30 located at each corner portion of the base. A brake mechanism 60, located at the centre of the trolley, includes a wheel unit and wheel brake apparatus for engaging said wheel unit for braking the trolley. A plurality of handles 50 is located on the frame connected to a plurality of cables 70 for cooperatively engaging with the wheel brake mechanism. This system forms a deadman’s braking system whereby only moving a handle relative to the frame disengages the brake. If the handle is released, the braking system automatically engages again. The support structure of the trolley may be arranged to fold. The braking mechanism may comprise a brake pad which is arranged to urge the wheel to a stationary position. The braking mechanism may comprise an elongate member which couples the both wheels of the wheel unit and may be arranged to rotate, the rotation may be caused by a cam member configured to transfer the linear motion of the cables into rotational movement.
