The present disclosure provides for a reversible and adjustable stopper assembly comprised of an upper frame, L-bracket, connector portion and stopping member. The stopper can be configured to be secured to at least two main types of press brakes. The stopping portion of the stopper is also reversible, allowing for less sheet metal to be inserted into the press brake, if desired. The stopper assembly can be slid in a horizontal manner, relative to the press brake to preserve the measurement of the sheet metal from one end of the press brake to the other.

A concrete bucket attachment for a track mini skid steer. The concrete bucket attachment includes a frame for supporting a polyurethane tub. The frame includes a connection plate for connection to a standard connector plate of the track mini skid steer. The tub is semitransparent polyethylene. The frame and tub are sized to conform to the lift capacity of the track mini skid steer.

An apparatus for the output of a fluid process material, in particular a process material in the form of concrete, mortar or adhesive, has a distributor boom comprising a plurality of boom arms, connected to each other at joints, having a process material delivery line formed by a plurality of pipe segments, which are preferably joint-connected to each other by pipe bends and rotating couplings. The delivery line is guided along the individual boom arms and fixed thereto. A tool, which is received on the distributor boom, has a device for the output of the process material. The tool has a buffer vessel, which receives the process material from the process material delivery line, and an output element for the output of the process material, fed from the buffer vessel, at an output location.

Methods, systems, and devices, are developed for in-situ placement of a concrete mix that can have the thixotropy to hold vertical dimension without containment, while maintaining pliability to be pumped into place and manipulated to a desired shape, and can be combined with concrete set accelerators, allowing subsequent layers of this concrete mix to be continuously stacked in place to build tall walls and such without the use of forms. Concrete without these special properties is pumped toward the point of placement where it is modified by injecting and mixing, into that line of pumped concrete, an admixture containing thixotropes, thickeners and/or set accelerators or other modifiers to provide these properties and other improvements. This method allows conventional plant batching with commonly available constituent materials for batching an economical concrete that is delivered to a jobsite and then is pumped most of the way to a point of placement.

A method of slip forming a concrete structure can include using a first slip form mold that travels along a path to form a portion of a concrete structure by delivering a first flow of concrete into the first mold through a first hopper. The first hopper can be configured to receive the first flow of concrete. The portion of the concrete structure can be modified using a second slip form mold different from the first mold by advancing the second mold along the concrete structure and, while advancing the second mold, delivering a second flow of concrete into the second mold through a second hopper that is configured to receive the second flow of concrete.

A trough-support system includes a trough, an arm rest and a handle. In some embodiments, the body of the arm rest is designed to curve around the arm of a user. The arm rest and handle can include one or more magnetic tool holders that can hold a tool or instrument. The handle can include a strap with a magnetic tool holder that can hold a tool or instrument. Various parts of the arm rest, handle and/or strap can be made of magnetic material to hold tools.

A funnel is formed with a planar base having a forward edge, a rearward edge, and parallel side edges. The funnel has side walls extending upwardly and outwardly from the side edges at an angle from horizontal. The funnel has a rear wall extending upwardly and rearwardly from the rearward edge at an angle from horizontal. The base and the side walls and the rear wall form a chamber with a forward passageway. A support assembly removably couples the funnel to an edge. The support assembly includes a forward support plate extending downwardly from the forward edge of the base at an angle from horizontal. The support assembly includes a rearward support plate extending downwardly from the base parallel with the forward support plate from a location spaced rearwardly from the forward support plate.
