A lifting and positioning apparatus for construction panels such as sheet rock, the apparatus including at least one lifting standard having a base, a fixed strut supported vertically from the base, a movable strut supported from the fixed strut, a guide and latch arrangement for retaining the struts in generally parallel relationship, a handle on the movable strut for elevating same in relation to the fixed strut and the base, and a panel engaging rail supported on the movable strut. The panel engaging rail may be supported at the top of the movable strut, in which case, two of the standards are used to elevate and position a panel against the underside of a ceiling framework. In an alternative embodiment, only one standard is used and includes a cleat-like rail at the bottom of the movable strut to engage the lower edge of a panel to be elevated along a vertical wall framework.
