Abstract:
An apparatus for rotating heavy objects, comprising: a table top comprising a first portion and a second portion; a base; a drive system; and an engagement mechanism for reversibly locking the first portion and the second portion together; wherein, the first portion and second portion are independently, pivotally disposed on the base such that each can move between a first, lowered position and a second, raised position; and wherein the first portion is further operatively connected to the drive system, further comprising a first and a second up limit switch; wherein, the first up limit switch prevents the drive system from further rotating the first portion, alone or when locked together with the second portion, when tripped by rotation of the first portion, and the second up limit switch prevents the drive system from further rotation of the second portion when locked together with the first portion, when tripped by rotation of the second portion.
