A ground tape applicator is configured to apply adhesive tape to ground surfacers. The ground tape applicator includes a plurality of rollers that guide the adhesive tape to the ground surface and apply the adhesive tape to the ground surface. The ground tape applicator includes a blade configured to engage with the adhesive tape to cut the adhesive tape to a desired length.

Ground tape applicator apparatus and method

A handheld sprayer (′) includes a fluid module (′) mounted to a drive module (′) at a static connection (′) and a dynamic connection (′). The static connection (′) supportably attached the fluid module (′) to the drive module (′). The dynamic connection (′) connects a drive () of the drive module (′) to a pump (′) of the fluid module (′) such that the drive () can power the pump (′) by the dynamic connection (′). The fluid contacting components of the handheld sprayer (′) are in the fluid module (′). The fluid module (′) can be mounted to and dismounted from the drive module (′) by a sliding motion.

This disclosure presents several options for spraying paint on large elevated surfaces. In a first example, a lift is equipped with sensors to move a painter along the wall in a serpentine pattern while maintaining a constant separation distance and orientation to facilitate spraying of the wall. In a second example, a spray stamp frame is positioned on the wall in a plurality of different positions to spray discrete portions of the wall by a slide bar that moves along the spray stamp frame at each position. In a third example, one or more cables are strung between vertical supports along the wall and a spray module is moved along or by the cables to spray the horizontal stripe, and this process is repeated to spray a plurality of horizontal stripes at different elevations to spray the wall.

A ground marking apparatus is configured to apply marking material to a ground surface. The ground marking apparatus includes a beam supported by a beam mount and extending along a beam axis. A carriage is disposed on the beam and movable on the beam along the beam axis. A carriage motor operably interfaces with the beam and is configured to move the carriage along the beam. A dispense arm is supported by the carriage and is configured to move relative to the beam as the carriage moves along the beam.

A ground sprayer includes a front portion and a rear portion. A marking fluid is stored in a fluid reservoir removably mounted in the front portion. A pump disposed in the front portion draws the marking fluid from the fluid reservoir through a manifold, and the pump drives the marking fluid out of a nozzle. An actuator is disposed in the rear portion and can activate the pump based on a command from the user. The rear portion includes a handle such that the user can fully support and operate the ground sprayer with a single hand.

An electro-hydraulic actuation system for a sprayer comprises a hydraulic system, a hydraulic actuator, an electric actuator and a sprayer. The hydraulic system is for pressurizing a hydraulic fluid. The hydraulic actuator is powered by the hydraulic system. The electric actuator controls actuation of the hydraulic actuator by the hydraulic system. The sprayer is actuated by the hydraulic actuator.

A pump for a striping machine includes dual check valves within its piston. At least one of the dual check valves is closed during an upstroke of the piston, thereby ensuring that the pump drives fluid during both its upstroke and its downstroke to maintain a desired ratio between a fluid output by the pump and a material solution output by another pump of the striping machine.

A hydraulic proportioning system has a flow divider providing hydraulic fluid to drive two hydraulic pumps. The flow divider provides set amounts of hydraulic oil to each of two pumps, and the pumps each provide one material of the plural component material downstream to a mixing manifold. The two materials are mixed at the mixing manifold before application. The flow divider drives each pump at a set speed depending on the volume of hydraulic oil provided to each pump. The flow divider thus determines the ratio of the first material to the second material provided to the mixing manifold by the pumps.
