Some illustrative embodiments of a fire tube implement for extraction and insertion of a fire tube may include an elongate shaft that is configured to extend outward and to be received within an opening in the fire tube. In some embodiments, the elongate shaft may carry at least one extender that is moveable between an extended position and a retracted position normal to a longitudinal axis of the elongate shaft. The at least one extender may be configured to engage an internal surface of the fire tube within the opening when the at least one extender is in the extended position. In some embodiments, a stabilizer may be laterally disposed from an exterior surface of the elongate shaft and securable to the fire tube. The elongate shaft may be operable by a powered machine.

A transport apparatus for use in the transport of a heavy structure includes a shape-adjustable adapter realized to adjust between an initial shape and a mating shape; and an actuator configured to effect a change in shape of the shape-adjustable adapter into its initial shape to facilitate positioning of the adapter relative to the structure; and to effect a change in shape of the shape-adjustable adapter into its mating shape to engage the shape-adjustable adapter with a surface of the structure. A method of securing a frustoconical structure during transport is further provided.

Described herein is a device for upending a tubular element with a longitudinal direction from a support surface at an outer end. The device has a support beam which runs substantially parallel to the support surface and is connected to the support surface at a support point. The support beam guides a coupling tool to which a wall part of an outer end of the tubular element can be coupled. The coupling tool is displaceable relative to the support surface with the support beam, from a clear position to a coupled position in which the tubular element outer end is engaged by the coupling tool. Also described herein, in addition to the device, is a method which makes use of the device.

A pile lifting chuck including a chuck housing which is inserted into an inner diameter of a pile and has extension-installing pockets vertically formed at predetermined intervals to face each other in a radial direction. The pile lifting chuck further includes a pair of extensions which are disposed in the pockets and installed to be movable in the radial direction and a chucking cylinder which has one end connected to any one of the extensions and the other end connected to the other one of the extensions and which is configured to, by using a reaction force on the any one of the extensions, move the other one of the extensions to chuck the pile.

A tool and method for hoisting an longitudinal end of an offshore wind turbine component which is in a horizontal orientation. The tool is after being attached to a lifting block to be moved into a proximate position in which gripping members of the tool are longitudinally spaced from the longitudinal end but the radial contour of the tool at least overlaps with the radial contour of the longitudinal end. While the gripping members are in a retracted position guiding actuators can move the tool from the proximate position into a gripping position longitudinally aligned with the longitudinal end in which the gripping members are movable to engage said surface of the longitudinal end, thereby connecting the longitudinal end to the tool and suspending the longitudinal end from the lifting block so that the longitudinal end can consequently be hoisted.

The present disclosure provides a pile lifting device capable of preventing the overturning of piles that can lift piles by chucking the piles using hydraulic pressure and prevent the overturning of the piles even when chucking is released during lifting, thus preventing accidents. According to an embodiment of the present disclosure, the pile lifting device capable of preventing the overturning of piles, which is connected to lifting equipment and used to lift piles, includes a balance plate which is connected to the lifting equipment to maintain a horizontal balance and a pile lifting chuck which is connected to the balance plate directly or via a plurality of first lifting cable and inserted into an upper inner diameter portion of the pile to hold the pile using a hydraulic force.
