ABSTRACT:
A stepladder for positioning equipment and material. The stepladder includes a head step assembly with one or two openings, and a lifting mechanism mounted to the head step assembly. The lifting mechanism removably receives a shaft at one end and the other end passing through one of the openings and removably receiving the equipment and/or material load. The stepladder is mounted over a wheeled platform. The shaft may include a tubular extension and a spring member for dividing the load weight between the stepladder and the shaft, when the latter is in contact with the supporting hole through the pulley housing that removably holds it. An additional shaft can be removably mounted to one of the openings to provide further stability to the structure.
