The carriage is supplied with electric power and hydraulic fluid from an attached flexible power track system which has a fixed end connected to a source of high pressure hydraulic fluid and a return sump and a source of electric power and a free end attached to move with the carriage. Alternatively, the entire hydraulic system may be carried on board the carriage.
