A surface treatment vehicle for manufacturing a wind turbine blade is provided, the vehicle including: a transportation unit for locomotion of the vehicle, and a filling unit for applying a filler material on a surface of the blade, wherein the filling unit includes: a dispensing head for dispensing the filler material, the dispensing head being moveably attached to the transportation unit, and a tank for storing the filler material, the tank being attached to the transportation unit and fluidly connected to the dispensing head. Having the surface treatment vehicle with the filling unit allows an easier, faster, safer and more efficient manufacturing of a wind turbine blade.

The present application includes methods, apparatuses, and systems for cleaning an aluminum wheel. In particular instances, a method of treating an exterior surface of an aluminum vehicle wheel comprising: blasting the exterior surface a first occurrence for a first duration at a first velocity using blasting media; blasting the exterior surface a second occurrence for a second duration at a second velocity using blasting media after blasting the exterior surface for a first duration, the second velocity being substantially lower than the first velocity; and, arranging the vehicle wheel in contact with vibratory finishing media and vibrating the vehicle wheel with the vibratory finishing media for a duration after blasting the exterior surface in each of the first and second occurrences.

A walk-behind, wet/dry grinder/polisher adapted for concrete floors does not use of pulleys, belts or chains. Maintenance is significantly enhanced, as such components are typically the first to wear out and cause replacement issues. A frame with forward and rear portions pivots about a single set of right and left wheels. A planetary grinding head, powered by a propane engine, is coupled to the forward portion of the frame. In contrast to all known designs, the engine is directly, mechanically coupled to the grinding head without the use of pulleys, belts or chains. The direct, mechanical coupling to the grinding head preferably uses a centrifugal clutch. A water tank and water feed line from the water tank to the grinding head facilitate wet floor grinding and polishing. The grinding head is also encased in a shroud coupled to a tube for dust collection associated with dry floor grinding and polishing.

A grinding device of a travel path, on which traveling wheels of a rail-type vehicle roll, includes a grinder which grinds a surface layer of a travel path, a frame on which the grinder is provided, and a device traveling wheel mounted on the frame. The device traveling wheel rolls along the travel path on the top surface of the standard rail extending in the extending direction of the travel path.

A method and apparatus is provided for treating a floor surface with zero-tolerance edging. The apparatus includes a frame and wheels mounted to the frame so the frame can travel over the floor surface. The apparatus also includes a motor mounted to the frame and a head assembly including a bottom plate. The bottom plate is operatively coupled to the motor so that the bottom plate is configured to rotate about a first axis. The bottom plate is positioned such that a tooling plate mounted to the bottom plate is configured to treat the floor surface including an edge of the floor surface intersecting a wall surface.

A floor processing system for a skid steer loader includes a shroud having an attachment device configured to removably engage with the skid steer loader; a central motor secured to the shroud and rotatably attached to an arm; a first rotary assembly secured to the arm; and a second rotary assembly secured to the arm. The first rotary assembly includes a first disc rotatably attached to a first motor via a first shaft; and a plurality of first cutters extending from the first disc. The second rotary assembly secured to the arm includes a second disc rotatably attached to a second motor via a second shaft; and a plurality of second cutters extending from the second disc.

A spacer device for a grinding roller, in particular of a grinding machine, including a main body to which at least two rolling bodies are rotatably mounted and wherein the spacer device can be supported by way of the at least two rolling bodies against a surface to be ground during a grinding process. At least one fixing device is arranged, preferably centrally, between the at least two rolling bodies and with which the grinding roller can be preferably releasably fixed to the spacer device. Furthermore, an adjusting device allows the grinding roller in a state of being fixed to the spacer device to be adjustable relative to the main body and/or at least one of the at least two rolling bodies.

A wheel grinder contains: a body, a work table, a vertical limitation frame, a movable adjustment portion configured to move vertically, a grinding wheel portion extending outward from the movable adjustment portion, and a motor fixed on the movable adjustment portion. The vertical limitation frame has two fixing holders, two mountings, and two first screw rods and two second screw rods which are inserted through the two mountings respectively and abut against a bottom of the movable adjustment portion. In addition, a stop cover is covered on the grinding wheel portion and includes a defining plate configured to define a connection shaft and an opening inside the defining plate.

This disclosure provides a floor grinding machine. The floor grinding machine includes: a body bracket; a grinding disc connected to the body bracket, wherein the grinding disc has a first position configured to grind a ground and a second position configured to replace a grinding member provided thereon; a first moving wheel provided on the body bracket; a second moving wheel connected to the body bracket, wherein the second moving wheel has a travelling position in which the second moving wheel is capable moving along the ground and an avoiding position in which the second moving wheel is away from the ground. The floor grinding machine has a first working state configured to grind the ground and a second working state configured to travel or to replace the grinding member. When the grinding disc is in the first position and the second moving wheel is in the avoiding position, the floor grinding machine is in the first working state; and when the grinding disc is in the second position and the second moving wheel is in the travelling position, the floor grinding machine is in the second working state. The floor grinding machine of the present disclosure solves the problem of inconvenient replacement of the cutter head and inconvenience of movement of the floor grinding machine in the prior art.
