Abstract: A brake trolley (28) for a continuous belay system comprising a body portion (29) and a stopper (42) connected to the body portion and configured to abut against the pulley. The body portion comprising a slideable support tube (30) configured to be mounted around a riding cable (2), a connection flange (34) attached to a first end of the slideable support tube and configured to be attached to the traction member, and a spacer plate portion (38) attached to the second end of the slideable support tube and interconnecting the stopper to the slideable support tube. The connection flange and the spacer plate portion both extend in transverse directions in relation to an axial direction (A) of the slideable support tube, and the thickness (w1, w2) of the spacer plate portion and the connection flange are smaller than an external diameter (D) of the slideable support tube.
