A sawing machine for cutting steel bar stock includes a rack assembly that has a plurality of stalls that are each configured to hold at least one elongated piece of metal in generally parallel alignment with the others. A chain drive is coupled with the plurality of stalls and is operable to move the plurality of stalls to align a selected stall of the plurality of stalls with a pushing position. A saw is arranged at or near a first end of the rack assembly and has a saw blade positioned perpendicular to the elongated pieces of metal held by the rack assembly. A pusher device is operable to linearly move a pusher member from a second end of the rack assembly toward the first end, such that the elongated piece of metal held by the selected stall is move by the pusher device to a desired cutting position.

Embodiments of the present disclosure provide surface treatment tools, methodologies, and/or treated turbomachine components. A surface treatment tool according to the present disclosure can include a lathe assembly having a lathe chuck for receiving a component thereon, wherein the lathe chuck rotates the component about a first axis of rotation, and wherein the component includes an exposed axial target surface; and a sander or burnishing tool coupled to the lathe assembly and including a sanding or burnishing surface thereon, coupled to a drive system, wherein the sanding or burnishing surface is oriented along a second axis substantially non-parallel with the first axis of rotation, such that the sanding or burnishing surface selectively contacts the target surface of the component to yield a polished target surface.

The application relates to wind turbine tower section production methods and in particular to methods of manufacturing a plurality of elongate tower segments for forming a wind turbine tower section, the tower section constructed from a plurality of elongate tower segments connected along their respective longitudinal edges. The tower section is formed from a plurality of cans connected end to end and is divided into elongate segments by cutting along two or more cut lines extending along the length of the tower. A method of providing a horizontal flange at the end of a wind turbine tower is also discussed, as is a vertical flange preassembly including a pair of vertical flanges for connecting the longitudinal edges of adjacent first and second tower segments.

An apparatus, such as for tree trimming, includes a mobile carriage having a frame and a pedestal supported by the frame. The apparatus further includes a boom, such as a telescoping boom that is secured to the pedestal through a boom support. The pedestal is pivotable with respect to the carriage frame so that the boom may be selectively operated in a variety of orientations. The mobile carriage of the apparatus is sufficiently compact to fit though tight openings, while also being capable of stably supporting boom extension for operation of a distal end of the boom at elevated heights.

A handheld ring cutter is disclosed. The ring cutter includes a body, a blade motor having a motor rotation axis extending in a longitudinal direction, a circular blade, a blade rotation axis extending in a lateral direction, a safety guard, and an electro-mechanical safety guard actuator. The drive shaft protrudes in the lateral direction out of the body, and the circular blade is mounted to the drive shaft outside of the body at a position spaced from the body in the lateral direction. The safety guard is located outside of the body at a position spaced from the body in the lateral direction, and the safety guard is aligned with the circular blade.

An extendable saw can include a blade housing coupled to a main body by at least one extendable member, the blade housing at least partially covers a saw blade and the extendable member can be configured to move the blade housing and the saw blade between a retracted position and an extended position relative to the main body. The extendable saw can also include a motorized unit coupled to the saw blade and configured to rotate or provide other blade movement to the saw blade and a switchable device or unit disposed on the main body and having at least one contact surface that is switchable between a magnetized or vacuum state and a non-magnetized state or non-vacuum state, respectively.

The safe and efficient cutting of window blinds can be accomplished by utilizing a blind cutting system which is configured to support and contain the blinds in a desired position, and to have a cutting saw move along a cutting plane such that a cutting blade will interact with the blinds and cut a predetermined portion from an end thereof. A framework is used to support the cutting saw and allow movement of a cutting blade in a very controlled manner, thus avoiding any possibility that the blade is positioned in a dangerous position during operation. Further, the travel of the cutting blade along a cutting path will create a cutting action in a controlled and defined manner. Further, the cutting blade is shielded on virtually all sides, thus eliminating the possibility of injury or harm to a user.

A flange bolt cutter for separating two connected flanges. The flange bolt cutter contains a circular saw blade connected to an flange mount which can be vertically adjusted relative to the flange mount and/or includes two arms which can be pivotally adjusted relative to each other.
