Employing a microcomputer and a user interface to control the operation of various motors and a linear actuator of a floor stripper improves efficiency and effectiveness while reducing vibration and sound levels during a floor stripping operation.

Floor stripper machine

A drive wheel assembly for a floor stripping machine permits a drive wheel to be selectively locked to and unlocked from a drive axle and reduces the quantity of debris that is able to accumulate on the tire of a wheel during a floor stripping operation.

Wheel coupler and scraper for floor stripper

A floor stripping machine blade of a blade assembly has a leading edge, when the blade assembly is attached to a floor stripping machine, at an angle that is other than perpendicular to the direction of travel of the floor stripping machine, said angle of the blade's leading edge being fixed or adjustable.

Blade arrangement

An improved walk-behind floor scraper incorporates a plurality of isolators between a main plate and cutting head to reduce vibration and a plurality of stops to prevent damage to the isolators.

A locker system includes one or more banks of electronic lockers. Each locker has a door lock that releasably retains the door in the closed position. The locker system also includes at least one barcode scanner selectively unlocks the door of at least one of the lockers. A locker manager is coupled to each of the electronic lockers via an electronic network. The locker manager stores a list of unique barcodes that are each associated with a locker rental plan including at least one locker account. Each locker account includes an activation indication, a use indication, a locker type indication, and a duration. The unique barcodes are printed or otherwise included on wristbands, which may be scanned at the barcode scanner to gain access to one or more of the lockers.

A caster wheel arrangement includes a base; a yoke rotatably mounted to the base via a kingpin; at least a first caster wheel rotatably mounted to the yoke; and an assist arrangement moveably mounted to the yoke. The assist arrangement facilitates travel of the caster wheel arrangement over a surface transition (e.g., a gap, a rise, etc.). Non-limiting example assist arrangements include a leading wheel, a leading variable radius wheel, a trailing wheel, a step member, and combinations thereof.
