摘要：
An apparatus includes a carriage, a platform, an extension member, and a spray tool member. The carriage moves along the track in a lateral direction. The platform is coupled to and positioned above the carriage. The length of the platform is greater than and orthogonal to the width of the platform and transverse to the lateral direction when in an operational state. The platform pivots about a fulcrum positioned between the platform and the carriage such that the front end and the back end of the platform move vertically in opposite directions. The extension member is movably coupled to the platform and has a longitudinal axis parallel to the length of the platform. The extension member extends away from the carriage in a first mode and retracts towards the carriage in a second mode. The spray tool member is coupled to the front end of the extension member.
