发明名称 Compact panel lifter
摘要 A simple, compact, hands free device that allows a single operator to vertically lift and hold construction panels to a desired height for securing to a wall surface. Downward foot pressure on one end of a slotted lever arm causes a panel lifting surface on the other end of the lever arm to rise. This lever arm is supported by a base support which also supports a locking arm. Once the desired height is reached, the device locks the panel into position. The operator is then free to move about, adjust, and finally secure the panel. Once the panel is secured, the locking arm is released by simple forward pressure. With the aid of a foot strap, the device can then be transported to the next panel ready for lifting. This device eliminates the use of hands, bending, or stooping during the process of lifting construction panels.
