A self-aligning mechanical pointer (10), includes a frame (12) attached to the front of a vehicle (14). A guide wheel (16) rides on a road surface and is rotatably carried by a wheel holder (18). The wheel holder (18) is connected to a swing arm (20), which pivots on frame (12) at point (22). An adjustable linkage member (24) connects swing arm (20) to a second swing arm (26). A guide rod (28) provides a sight means for an operator to align the pointer (10) with an intended target.

A tape removal apparatus adapted to be towed behind a vehicle for removing marking tape from a road comprises a road frame hitched to the vehicle and having a pair of wheels to allow the road frame to be towed behind the vehicle and a pickup mast having a center section coupled to the road frame, a lower section extending from the center section toward the road and having a drive roller configured to engage the tape on the road to remove the tape from the road, an upper section extending from the center section toward the vehicle, and a pinch roller. The pinch roller is configured to receive the tape from the drive roller as the tape removal apparatus is towed behind the vehicle.

A traffic stripe including a first profiled portion having improved reflectivity and a second raised portion which provides an audible indication of its presence to a driver. Also, a method and apparatus for applying the traffic stripe including a vehicle having an apparatus for applying the traffic stripe, an applying assembly for dispersing a reflective material over the traffic stripe, another applying apparatus for applying an anti-adhesion agent, and a deformation apparatus disposed rearward thereof for forming interval grooves in the traffic stripe. The application of the anti-adhesion agent directly onto the traffic stripe or onto the deformation apparatus prevents the freshly applied traffic stripe from lifting off the road surface and adhering to the deformation apparatus.

A ribbon marking tool (10) for dispensing a length of warning tape (14) along the ground above a buried conveyance tool includes a housing (20) within which a roll of warning tape (36) is mounted for rotation. A mechanism (32) within the housing serves to feeds the tape out through the housing and to staple the tape to the ground and to sever the tape once a sufficient length of tape is dispensed.

A method and an apparatus are disclosed for cutting rumble strips in the surface of a roadway. The apparatus is a self-propelled machine which includes a frame and a drive mechanism mounted to the frame and adapted for advancing the machine across the surface of the roadway. The machine also includes a generally cylindrical cutting drum that is mounted on the frame for rotation about an axis that is disposed generally parallel to the surface of the roadway. A plurality of cutting teeth are mounted on the outer surface of the drum in a predetermined pattern, and a mechanism is provided for rotating the cutting drum about its axis. The drum is maintained at a predetermined position with respect to the surface of the roadway so that the cutting teeth will cut into said surface a relatively constant, predetermined depth as the drum is rotated about its axis while the machine is advanced along the surface of the roadway. When the drum is rotated about its axis while being maintained at the predetermined position with respect to the surface of the roadway as the machine is advanced therealong, the cutting teeth will cut a series of spaced parallel rumble strips into the surface of the roadway. This improved machine is capable of smooth and uninterrupted cutting operation while advancing along the surface of the roadway at greater speeds and without the vibration that is characteristic of other known machines.

Apparatus and method for applying temporary raised pavement markers (TRPM) to roadway surfaces comprises primary and auxiliary conveyors wherein an upstream end portion of the primary conveyor is able to extend, for example, over the rear bed portion of a roadwork truck so as to permit an operator, stationed upon the bed portion of the truck, to deposit pavement markers upon the primary conveyor. In accordance with a first embodiment of the invention, a slide mechanism is disposed adjacent to a downstream end portion of the primary conveyor and adjacent to an upstream end portion of the auxiliary conveyor for transferring pavement markers from the primary conveyor to the auxiliary conveyor when the absence of a pavement marker upon the auxiliary conveyor is detected. When pavement markers are present upon both conveyors, the pavement markers are conducted to applicator mechanisms for application to the roadway surface. A second embodiment of the invention comprises the use of a pair of wheel applicators for applying the temporary raised pavement markers (TRPMS) to the roadway surfaces.

A striping layout machine is adapted to apply reference marks to a roadway in a safe and expedient manner. The machine has an array of features to enhance the safety of operating personnel as well as passing motorists. Equally effective on surfaces of different types, the machine has the capability to pre-mark as much as twenty miles of roadway in an hour. A unique, telescoping boom produces layout lines which may range from zero to twenty feet. The machine employs a lime and water solution for marking instead of paint. The lime and water solution is not permanent and will wash away at the first rain after the roadway has been striped thereby leaving an unmarred, clean stripe.
摘要:
The bead dispenser is formed from rotational molded plastic such that a hole is cored through the center of the dispenser which allows the linkage to travel through the dispenser and locate the dispenser door on the opposite side of the dispenser from the spray gun. A number of panels across the slot opening may be adjusted upwardly and downwardly to vary the width as desired by the operator.

An assembly is provided for excavating cavities in a road surface for a variety of purposes, among them, the formation of rumble strips, the installation of light reflective road markers, the milling of potholes, boring of holes for various purposes and the like. The system is used in combination with a vehicle having a motor powered vertically movable rear lift gate which in use defines a vertically displaceable substantially horizontal platform. A cutting apparatus is secured to the upward facing surface of the lift gate with the actual cutting portion being mounted on a rotatable drive shaft extending laterally of the gate, such that the cutting portion projects at least partially below the bottom surface of the lift gate, whereby with the gate in a lowered position, the cutting portion can engage the surface of the road on which the vehicle resides. A motor is secured to the upper surface of the gate powers the drive shaft. The vertical position of the lift gate is adjustible with respect to the surface of said road, to control the depth of cut and thus the degree of excavation produced by the cutting apparatus.
摘要:
Apparatus and method for applying temporary raised pavement markers (TRPM) to roadway surfaces comprises a conveyor upon a wheeled vehicle wherein an upstream end portion of the conveyor is able to extend, for example, over the rear bed portion of a roadwork vehicle so as to permit an operator, stationed upon the bed portion of the roadwork vehicle, to deposit pavement markers upon the conveyor. A pair of wheel applicators are used for applying the temporary raised pavement markers (TRPMs) onto the roadway surface. A hitch mechanism is also used to provide hinged movement between the tow bar of the towed wheeled vehicle and the mounting bar of the towing roadwork vehicle so as to permit independent elevational movement of the towed wheeled vehicle relative to the towing roadwork vehicle.
