A lifting and moving device, and a method of using the device comprising a frame having a first ground engaging end with at least one wheel for providing a movable first ground engagement and a second ground engaging end with a pointed end for providing a fixed second ground engagement for the frame. A lifting and moving support extending between the first and second ground engaging ends is adjustable in length for providing one or more distances between the first ground engaging end and the second ground engaging end. A lifting device is retractable from a position on the support and the frame is movable about a pivot point provided by the second ground engaging end.

A manhole installation jig including at least one example with: a manhole collar attachment system configured to removably attach the installation jig to a manhole collar having an upper edge, the manhole collar configured to support a manhole lid; a plurality of surface brackets extending outward from the manhole collar; each surface bracket comprising a ground engagement surface configured to engage the ground surface exterior of the manhole collar; and the manhole installation jig configured to support the manhole collar with the upper edge substantially at a vertical position level with the ground surface.

The present invention relates generally to a claw device for installing, removing, and repairing a manhole assembly. Claw device may include a base assembly and two or more arm assemblies. The arm assemblies may be configured to pivot in response to movement of a slide along an axis of a shaft extending upwardly from base assembly. In particular, when a lifting force is applied to the slide, one or more grip pads of arm assemblies may be configured to move inwardly toward the shaft and frictionally grip a surface of the manhole assembly. In one aspect, at least one arm assembly includes an extending member having a plurality of positions for adjusting the length of at least one arm assembly. Advantageously, claw device may be adjusted to accommodate for manhole assemblies of different diameters or other objects having various shapes and sizes.

The present disclosure relates to the field of construction, and, more particularly, to the adjustment of the position of a floating manhole or the replacement of a manhole with a new manhole so that the manhole is aligned with the connecting surface, e.g., the roadway. The object of the disclosure is to make it quicker, easier, and cheaper to adjust the position of a floating manhole, or to replace the manhole with a new manhole by aligning the manhole surface with the connecting surface, e.g., the roadway.

A cap assembly can include a cap holder device with a plug member and a cap holder. The cap holder device is positionable in an end of a conduit positioned along a roadway. The cap holder is carried by the plug member and includes a magnetic element and a connector. The connector is connectable to the magnetic element to the plug member such that the magnetic element is movable relative to the plug member so as to position the magnetic element for releasably holding a cap that covers the end of the conduit when the plug member is positioned in the conduit. The cap assembly can be a debris cap insertable in a conduit, an end of a pipe, or other opening.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

The present specification discloses an anchored hole cover for a bore hole cored from a paved surface that includes a cover plate configured to cover the bore hole and support vehicular traffic. An anchoring mechanism is attached to the cover plate and extends down into the bore hole. The anchoring mechanism is configured to be actuated by a user torque input that is transmitted through a linkage system to cause an anchoring mechanism to selectively engage or disengage the wall of the bore hole. When the anchoring mechanism is engaged with the wall, the anchored hole cover is prevented from being unintentionally extracted from the hole. The anchored hole cover effectively provides a temporary cover for a bore hole in a road, parking lot, or other paved surfaces that supports vehicular traffic, that prevents extraction due to vibrations of passing traffic, thus preventing damage to cars and their occupants.

A manhole cover locking apparatus that can promptly release the pressure in a sewerage pipe, suppress the lifting height of the cover, and stabilize the cover when lifted by pressure, including a lock main body, a hook, an engagement part that engages a claw for opening the cover; and a hook receiver on a receiving frame. The lock main body is attached rotabably about a pivotal support, and has a pressing part on a peripheral side of the cover with respect to the pivotal support part. A claw abutment surface that abuts against the claw is formed on an upper surface of the pressing part. When the hook and the hook receiver engage with each other, the claw abutment surface and an upper surface of the receiving frame are located at substantially the same height.

Embodiments generally relate to modular access covers. Example embodiments relate to an access cover assembly comprising: a first set of modular access covers and a second set of modular access covers, wherein in each set, adjacent covers are coupled; and a support frame comprising end frame pieces, side frame pieces, wall boxes, and a support beam. The end frame pieces and side frame pieces define a support plane to support the first and second sets of modular access covers. The wall boxes define a support surface to support the support beam and the end frame pieces, and the support surface is offset from the support plane and the wall boxes are connected to the end frame pieces and receive respective ends of the support beam.

The use of a self-driving vehicle to automatically find manholes, and for each remove the manhole cover from the manhole, and thereafter put the manhole cover back in position on the manhole. In some embodiments, while the manhole cover is removed, the self-driving vehicle is used to automatically place a tool above or within the manhole. Accordingly, a self-driving vehicle can automatically inspect, repair, or maintain manholes that are positioned in roadways. The data can then automatically be gathered without human intervention.
