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.

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.

The invention relates to a device for cutting concrete piles. The device having a frame, gripping means connected to the frame and including at least two opposing gripping parts, which are movable at least closer to each other to form a closing grip around a pile and further away from each other to release the pile from the closing grip, and sawing means, which are arranged to perform a back and forth sawing movement on the two opposite sides of the pile moving along a horizontal guide rail attached to the frame and which is further arranged to turn towards the pile to be sawed and back around their rotational axis. The invention further relates to computer program means suitable for controlling a device according to the invention to perform a desired sawing profile in the concrete pile.

Disclosed herein are a treatment apparatus and method for a waste steam generator, and an installation method of a treatment apparatus for a waste steam generator. The treatment apparatus includes a cutting part for cutting a body of a waste steam generator, a driving part for driving the cutting part, and a support frame for supporting the cutting part and the driving part, wherein the support frame is coupled to an outer peripheral surface of the body of the waste steam generator in a divided state, and the cutting part is driven and cuts the body in a state in which the support frame is coupled to the outer peripheral surface of the body. Consequently, since the treatment apparatus is easily moved and installed, an installation time of the treatment apparatus may be shortened and an exposure time of a worker can be reduced.

A tool assembly is provided with an integrated support fixture and assemblies for orienting the tool at different angles relative to a workpiece. A guide rail assembly is provided that defines a travel path for the tool slidably supported thereon. The support fixture is configured to support the tool assembly on a workpiece so that gravity can assist movement of the tool across the workpiece. The guide rail assembly is mounted on a miter plate that can be oriented at different miter angles relative to the support fixture. The tool may be supported on the guide rail assembly to permit pivoting of the tool perpendicular to the miter angle. Another assembly may be provided that permits pivoting of the guided rail assembly at an orthogonal angle.

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.

A track saw assembly is provided including a track saw (i.e., a circular saw) having a shoe translatable upon a track. Various mechanisms control plunging of a saw unit and saw blade of the track saw relative to the shoe. For example, a plunge lockout mechanism is provided to prevent engagement of a trigger and prevent movement of a plunge mechanism. Various mechanisms control bevel angle adjustment of the saw unit relative to the shoe. For example, a linkage is provided and is operable to shift between a first position and a second position. In the first position, a bevel angle is restricted within a first bevel angle range. In the second position, the bevel angle is restricted within an expanded second bevel angle range. Other concepts relate to the interface between the shoe and the track and a clamp which secures the track to a workpiece.

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.

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.
