A lifting clamp for an object comprises a plurality of plates stacked and connected together to form seat for a portion of the object, a lifting portion for connecting to a crane or other machine, a pivot leg pivotally connected to the stacked plates for opening the seat, and a lock for selectively locking the pivot leg in a clamped position whereby it grips the object.

A boom clamp attachment has a gib frame, a boom quick-connect, a shaft arm axle, a shaft arm torque assembly, and at least one gib clamp assembly. The gib clamp assembly has a clamp support member having a first gib clamp at a first end and second gib clamp at a second end. The gib clamp has a fixed finger and a moveable finger, the moveable finger controlled via hydraulics. The boom clamp may hoist, tilt, and position an assembled section of panels.

A rail lifting head (10) comprises a head gate member (20) defining a gate aperture (22), a rail support member (24) removably secured to the gate member (20) and adapted to support a rail vertically within the gate aperture (22), and a head cartridge (100) which is removably secured to the head gate member (20). The head cartridge (100) includes two opposed vertical rollers (128) which support a rail laterally within the gate aperture and a fixing (112) which secures the head cartridge (100) to the head gate member (20). The rail support member (24) is removable from the head gate member (20).

A lifting tool assembly is disclosed, including a crossbar having a long axis spanning between first and second end portions. A first hook member is pivotably suspended from the first end portion and a second hook member is pivotably suspended from the second end portion. The end portions are symmetrically angled relative to the long axis and each hook member includes first and second finger structures.

An articulable lifting attachment is provided for a mechanical articulated arm. The articulable lifting attachment comprises an attachment body, a clamping head and a drivable articulator coupling interposed between the attachment body and the clamping head. The clamping head is configured to provide two different clamping forces from different directions to ensure that irregular objects can be lifted safely.

A method of manufacturing a wind turbine blade (10) is provided, the method comprising the steps of providing a first shell half (38) and a second shell half (36), providing at least one shear web (50) having a web body (61) arranged between a first mounting flange (62) and an opposing second mounting flange (63), and providing a lifting assembly (65). The lifting assembly comprising at least one crane device (68), a lifting rail (69) suspended from the at least one crane device (68), and a plurality of lifting clamps (70, 72), each lifting clamp being connected to the lifting rail (69). The method further comprises the steps of attaching the lifting clamps (70, 72) to the shear web (50), lifting the shear web (50) with the lifting assembly (65), lowering the shear web (50) into the first shell half (38) with the lifting assembly (65), bonding the first mounting flange (62) of the shear web (50) to an inner surface (66) of the first shell half (38), detaching the lifting clamps (70, 72) from the shear web (50), bringing the first and second shell halves (38, 36) together, and bonding the second mounting flange (63) of the shear web to the second shell half (36).

A gantry assembly includes a main beam extending between a first and a second end. A plurality of legs including a pair of first legs and a pair of second legs attached to the main beam. A pair of first trolleys is slidably attached to the main beam. A first girder is attached to each one of the first trolleys and extends outwardly from the first trolleys for movement with the first trolleys. The first girder includes a pair of posts having a first and a second post disposed spaced from one another. The first post is attached to the first girder and extends downwardly from the first girder. The second post is slidably attached to the first girder and is movable along the first girder toward and away from the main beam allowing the gantry assembly to have different widths to accommodate for a single or double railway bridge.
