Various embodiments relate to a rivet element supply unit for providing rivet elements, wherein the rivet element supply unit comprises a rivet element provision unit and a handling unit, wherein the rivet element provision unit for conveying the rivet elements comprises a spiral conveyor having a longitudinal axis and a spiral, which extends around the longitudinal axis, wherein the longitudinal axis is inclined to the direction of gravity, wherein the rivet element provision unit has a pick-up region to which the spiral conveyor supplies rivet elements and from which the handling unit picks up the rivet elements for transporting to a rivet element receptacle.

A concrete nailer has a cutout defined by a magazine. The cutout is disposed proximate the drive track of the concrete nailer and provides the concrete nailer with sufficient reach to perpendicularly nail a complete range of U-shaped channels or track available to the job site against concrete, even though the magazine accommodates both long and short nails. The concrete nailer has the added ability to nail thick boards like 2×4's to concrete.

The present invention provides various aspects of support for a fabrication facility capable of routine placement and replacement of processing tools in at least a vertical dimension relative to each other.

Fastener delivery apparatus for automatically selecting and delivering fasteners such as rivets to a setting tool. The fasteners are pre-loaded in a package and dispense via at least one fastener delivery tube that interconnects the setting tool to a fastener feeder device. The fastener feeder device releases selected fasteners from the package into the delivery tube. The fasteners are transportable individually or in groups in the tube from the feeder device to the tool. A transfer station attached to the tool or the delivery tube transfers a fastener from the delivery apparatus into the tool, transfer station is adjacent to the tool so that a delivered fastener may be inserted by the transfer station into the tool and a second position in which it is clear of the tool so as to permit the tool or a portion thereof to move towards a workpiece to insert a smooth, rapid and reliable delivery of fasteners of various sizes and types to the nose of a setting tool in any particular order and provides all the fastener types for any particular work cycle.

A process and tool for installing and removing various kinds of wear parts used with earth working equipment. The process and tool allows the operator to remove and install the wear parts at a safe distance so that the operator is physically remote from the potential risks of the removal and installation process. The tool may be manually operated via an operator or the tool may be a semi-automated or fully automated.

A bolt installation and removal (BIR) system is used for assembling and disassembling a nuclear vessel. The BIR system includes a platform with a stand for supporting the nuclear vessel. A track extends around an outside perimeter of the platform and multiple tool carts include wheels that roll on the track. Tool towers are located on the carts and include tool assemblies configured to install and remove bolts on the nuclear reactor vessel. Magazine towers also extend up from the tool carts next to the tool towers and include magazines that hold bolts for exchanging with the tool assemblies. Drive mechanisms move tool heads in the tool assemblies around a first vertical axis, vertically up and down, and laterally to more simply and reliably install and remove the bolts in a radioactive underwater environment.
