A portable sawmill which has an elongate central portion, at least one hinged foldable extension portion, laminated rails, detachable axle/wheel combinations, a tow bar, and adjustable legs. Spacers are received between each rail and the respective support structure for both the central portion and the extension portion, including one spacer a first portion of which is disposed between and attached to each rail and support structure of one of the central portion and the extension portion and a second portion of which is slidingly receivable between each rail and support structure of the other of the central portion and the extension portion as the extension is unfolded for use. A pull cable, when an actuation lever is engaged, effects pivotal movement of a cam to which another pull cable is attached for actuating the engine throttle for cutting wood. At least one other pull cable or other actuation member is attached to the cam to actuate at least one other device upon the actuation of the throttle.

A mobile ordnance disposal system to dispose of unexploded ordnance in situ by cutting open the ordnance casing and subjecting the explosive material to heat in order to burn the explosive material held within the casing in a controlled manner instead of generating an explosion to effect disposal. By using the system, the operator may remain at safe, remote distance controlling the system operation.

A sawmill carriage includes a frame having a handle, translation structures connected to the frame towards lateral sides thereof, a sawmill head, and a pair of transportation wheels rotatably connected to the frame towards a longitudinal end thereof. The translation structures are mountable on rails of a log support structure that can support a log. The rails extend in a longitudinal direction and enable travel of the sawmill carriage in the longitudinal direction when the sawmill carriage is mounted thereon. The sawmill head has a saw blade, a portion of which is positionable to cut the log positioned on the log support structure when the sawmill carriage is mounted on the rails, and the sawmill carriage travels in the longitudinal direction. The handle is positioned to enable tilting and/or transportation of the sawmill carriage. A kit and method of using the sawmill carriage are also provided.

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 bandsaw assembly for cutting large diameter workpieces such as turbine rotors, heat exchangers or shafts at a plant or factory and a method of using the same is disclosed. The assembly includes a frame; ground-engaging wheels or a track provided on the frame; a plurality of spaced apart towers extending vertically upwardly from the frame; a rotatable drive wheel mounted on each tower, said drive wheel being horizontally oriented and presenting a vertically oriented circumferential surface; a motor operatively engaged with one or more of the drive wheels; and a bandsaw blade passing around the wheels and being in contact with the circumferential surfaces thereof; said blade being selectively driven by the drive wheels. The towers are variable in length to raise or lower the blade. The assembly is reduced in width for transportation or storage and increased in width for operation.

A band saw machine base structure includes a base box having a receiving space. A seat is connected to an underside of a band saw machine. The base box is mounted to the seat and the band saw machine, or the base box is connected to an underside of the seat. By arranging the base box mounted to the seat to protect the band saw machine to avoid collisions during transportation and facilitate packaging, or by arranging the base box connected to the underside of the seat as a stand to increase the height of operation of the band saw machine.
