1. An improved flotation drive system for use in conjunction with an existing corner system, the flotation drive system comprising:
a tube leg having an upper flange and a lower flange, the upper flange being adapted to connect to an existing corner system; a gearbox having a top surface, a bottom surface, a pair of opposite front surfaces, a pair of opposite side surfaces and a hollow bore extending between the pair of opposite front surfaces at the center, the gearbox being mounted to the lower flange of the tube leg; a tube extension member with a first end and a second end, wherein the tube extension member further comprises a flange attached to the second end of the tube extension member; a gear motor having a drive shaft coupled to transmit the torque to the gear box, the drive shaft being housed inside the tube extension member, the gear motor being connected to the flange of the tube extension member; and a fully keyed shaft being inserted into the hollow bore of the gear box, wherein the fully keyed shaft extends through the gear box so that the keyed shaft protrudes through each of the pair of opposite front surfaces of the gear box. |
