An autonomous ground maintenance system comprising a vehicle comprising a chassis supported upon a ground surface by ground support members, a container supported by the chassis, the container defining a discharge outlet operable to disperse treating material held within the container to a target area of the ground surface, a gate adapted to selectively open and close the discharge outlet, a sensor adapted to identify the target area, and an electronic controller supported by the chassis, the controller being in communication with the sensor and the gate. The controller is adapted to position the chassis at a location proximate the target area such that the discharge outlet is capable of delivering the treating material to the target area and energize the gate to open the discharge outlet.

A lifting apparatus has a handle and a scissor grip. The scissor grip is actuated by pushing the handle downward or by lifting it upward. Each end of the scissor grip comprises a bracket for coupling to opposing edges of an object to be lifted. As the handle is raised, the scissor grip actuates, squeezing and holding the object between the brackets. Alternatively, in some embodiments, as the handle is raised, the scissor grip may actuate, expanding and exerting outward force and thus holding an object from an interior. A user may then easily transport the object to the desired location, place the object without bending, and may release the object from the scissor grip by pressing downward on the handle and pivoting it to release at least one bracket from the side of the object.

A memory stores, in advance, target line information indicating an arrangement target of an object to be conveyed and related to a target line denoted by at least one of a curve or a polyline. A controller is configured to: calculate, based on the target line information, target information which is at least one of information about a target coordinate of the object and information about a target direction of the object; calculate, based on the at least one of the coordinate of the object and the direction of the object detected by the detector, detection information which is comparable with the target information; calculate a deviation of the detection information from the target information; and cause a display to display a moving direction of the object which allows the deviation to decrease.

A road plate moving system and method is disclosed that makes it easier, safer, and more economical to move road plates. A frame detachably attaches to a road plate at the centre of the road plate, and the frame is detachably attached to a vehicle, and the frame is attached to rollers that straddle the road plate and are configured to move in the desired direction of travel. Each roller has a lifting mechanism to adjust the height of the frame relative to the bottom of the rollers. In use, the frame is attached to the road plate, and the road plate is lifted off the ground by the rollers lifting the frame, and the frame and road plate are pulled forward or backwards by the vehicle to move the road plate, which is then lowered to the ground. In a second embodiment, the road plate is lifted by a lifter located above the centre of the road plate.

A series of modules serve to provide a base for walkway members to be assembled into a walkway. Modules provide for support and orientation of walkway members and the ability to produce complex walkways with segments at varying orientations. In a preferred embodiment, a base mat is sized to engage walkway members. Using a combination of a number of base mats and walkway members, segments of walkway of any desired size can be readily assembled. Reflective and non-slip surfaces can be applied to increase safety when in use.

An asphalt paving system comprising a plurality of dispensing shafts and a plurality of rolls of pavement reinforcing membrane. The plurality of dispensing shafts are adapted to be mounted on an asphalt paving machine, where at least a portion of at least one dispensing shaft extends from at least one side of the paving machine, and at least a portion of at least one dispensing shaft extends to a front of the paving machine. Each roll of pavement reinforcing membrane is supported by one of the plurality of dispensing shafts. As the asphalt paving machine moves, the plurality of dispensing shafts dispense the pavement reinforcing membrane continuously beneath the asphalt paving machine and the hot asphalt material is dispensed from the hopper on top of the pavement reinforcing membrane beneath the asphalt paving machine.
