    Abstract: In accordance with the present invention, a playground carriage (10) is provided for moving people (100) from one play area to another. The playground carriage comprises a rotatable support pipe (12) having a first end (14) and a second end (16). The support pipe extends between a first vertical column (18) and a second vertical column (20). A manually-operated crank extends between the first vertical column and a third vertical column (48). The first end of the crank is coupled to the first end of the support pipe so that manually turning the crank rotates the support pipe. A carriage (28) for carrying people is mounted to the support pipe. The carriage is advanced along the support pipe by a carrier assembly (102). The carrier assembly comprises a carrier (30) which propels the carriage and a brake (104) which is capable of bringing the carriage to a stop.
