摘要： An apparatus for lifting a panel to a ceiling has a post having an upper end and a lower end, a spring in the post between the upper and lower ends for at least limited longitudinal compression of the post against a spring force, and a foot pivoted on the lower end about a foot axis transverse to the longitudinal axis. A handle is pivoted on the post between its ends about a handle axis generally parallel to the foot axis and a panel-engaging support bar is pivoted on the upper end of the post about a bar-pivot axis generally parallel to the foot and handle axes, extends perpendicular to this bar-pivot axis, and has one end provided with an outwardly directed cleat. Thus this bar can be engaged under the panel with the cleat against an edge of the panel. At least one bar spring is operatively engaged between the bar and the post for biasing the bar into a position extending perpendicular to the post.

摘要： A ceiling tile replacing and positioning apparatus is disclosed in which a frustum-shaped frame is provided. An encircling flange on the larger base end of the frustum provides a platform upon which the ceiling tile may be rested. Pins project perpendicular to the flange to hold the tile in place. A handle including a sleeve which is pivotally and releasably attached to the frustum-shaped frame at the frustum smaller base makes the apparatus usable from various angles.

摘要： A reliable swiveling fastening mechanism that allows a plate to be horizontally, obliquely and vertically fastened comprises, in the position of use: a vertical supporting profile to be arranged at the top of the mast, coaxially to the mast; two parallel backing plates mounted so as to swivel on the supporting profile and interconnected on one side by a plate carrier fastening component and on the other side by a U-shaped vertical position stop attached to the backing plates and arranged in such a way that the plate carrier fastening component is parallel to the supporting profile when the supporting profile is in contact with the vertical position stop; and a retractable stop supported by at least one backing plate so that the plate carrier fastening component forms an angle between 10° and 80° with the supporting profile when the supporting profile is in contact with the retractable stop.

摘要： A sheetrock lifting device including a base with a protrusion centrally disposed on a front side of the base. A plurality of locking caster wheels is disposed on the base and on the protrusion. A pair of stanchions is used to house a battery and a manual wench. A pair of support rods supports the device by connecting the stanchions to the protrusion. A pair of stabilizing beams further supports the stanchions. A pulley device containing a pulley arm, pulley, and pulley cable is disposed on the stabilizing beams. An electric wench is disposed between the stabilizing beams and is in operational communication the battery. The electric wench raises and lowers a telescoping tube to which is attached a drywall frame. A manual wench alternately raises and lowers the telescoping tube with a cable hook connected to a ring on the telescoping tube.

摘要： A sprinkler drop ruler is provided for measuring the sprinkler drop from a roughed-in outlet. The sprinkler drop ruler includes a rigid frame having an opening, a handle connected to the rigid frame and in fixed relation to the rigid frame, and a ruler with an end shaped to seat in the opening and configured to move inside or along a side of the handle in order to measure a sprinkler drop. The sprinklerfitter may thus use the sprinkler drop ruler in order to measure the sprinkler drop. In this way, the sprinklerfitter does not need to climb a ladder to measure the sprinkler drop.
