ABSTRACT:
Preparation of precast concrete slabs on a casting bed is facilitated through the use of a lay-out cart which moves along over the bed on wheels which engage parallel rails on opposite sides of the casting bed. Production hardware for a days casting can be loaded on the cart and positioned at the proper longitudinal and transverse positions on the bed by workmen riding on the cart and placing the hardware on the bed through an access opening formed through the cart. The access opening is preferably at least as wide as the bed to provide access to the bed across its entire width, and a fixed scale and movable indicator are associated with the access opening to locate specific positions transversely of the bed. A longitudinal scale extends the length of the bed and the cart carries an indicator which is movable along the longitudinal scale to locate positions along the length of the bed.
