Abstract: A paver installer (10) is described for receiving and carrying a paver from one location to another location. The paver installer has frame (12) comprising a pair of spaced apart frame members (18) and a longitudinal axis disposed between. To add strength, at least one brace member (24) is disposed between the frame members. Proximate the lower portion of the frame is a wheel assembly(26). So that pavers (62) can be place on pedestals (72) having varying heights above grade, the paver installer has a U-shaped platform (46) slidably mounted to the facing away from the wheel assembly. Substantially cylindrically shaped sleeves (54) are mounted to the platform which respectively slidably engage the frame members. To move the platform along the longitudinal axis, a self locking screw lift (34) is mounted to the at least one brace member and the platform. A shim (60) is provided on the platform to prevent damage to the paver and provide an adjustable fit.

Abstract: A small vehicle lift of the parallelogram type is described wherein parallel pivoting legs are pivotally attached at their opposing ends to a base and a support platform, whereby the lift ranges from a lowered state wherein the support platform is in close parallel relation to the base and a raised position wherein the support platform is in spaced parallel relation to the base. Both the support platform and the base pivotally bear the legs within channels and thereby surround the legs at opposing planes adjacent the planes wherein the legs pivot. The channels within the base also have wheels rotatably mounted therein to allow the lift to be easily transported. Two opposing pivoting legs are affixed together by a bridge member which is pivotally connected to a linear actuator, which is in turn pivotally connected to the base. Actuation of the linear actuator thereby raises and lowers the support platform with respect to the base.

In order to make it possible to move the work spindle axially without help of the driving device in the case of an emergency, the connector includes a connection which is stiff in the axial direction of the work spindle, and which includes two parts which are rotatable in relation to each other against a certain friction resistance around an axis, which is concentric to the work spindle.

Abstract: A lifting and moving portable apparatus and method that includes a beam extending across the manhole cover supported at one end by a pivot member resting on the surface outside the manhole periphery and supported at the other end by a pair of wheels riding on the surface outside the manhole periphery. A lifting device is mounted on the center region of the beam for securing the cover and lifting the cover above the cover rim or surrounding surface. Once lifted, the operator can roll the beam and cover assembly through an arc about the pivot axis to expose the entire manhole. Means are provided to stabilize the cover in the horizontal and angular position relative to the beam so that the cover assumes the same angular position relative to the manhole when returned to the closed position.

Abstract: The scaffolding comprises a post having a plurality of vertically aligned and equally spaced studs protruding on one of its surfaces. A frame supporting a work platform can move along the post, a sleeve being attached to the frame for guiding it along the post. The sleeve, the frame and the work platform partially surround the post. A lifting apparatus, installed on the sleeve, comprises a rotatable endless screw which is parallel to the post and which has a peripheral and helical flange which bears on the studs. An engine, an electric power drill or a manual handle will rotate the endless screw via one or two speed reducers. The rotation movement of the endless screw will result in the axial displacement thereof along the post, carrying the frame and work platform along with it. Another embodiment of the invention comprises a work platform which is supported at both of its ends by a lifting apparatus movable along a post.
