Equipment for self-positioning handling of aluminum profiles for rail vehicle, including a handling and lifting mechanism, a steel beam fixed on and being driven to lift by the mechanism, 2-DOF spatial mechanisms fixed on the steel beam and mechanical clamping jaws fixed on a clamping jaw connecting seat; the 2-DOF spatial mechanisms includes a cylinder supporting seat, four connecting members on an outer ring of the cylinder supporting seat hinged respectively to four first connecting rods; wherein, two of the first rods are hinged to first ends of two ball joint connecting rods of which second ends are hinged to the clamping jaw connecting seat; the other two first rods are hinged to first ends of two second connecting rods of which second ends are hinged to the clamping jaw connecting seat; a piston rod of a cylinder center of the cylinder supporting seat driving the clamping jaw connecting seat.

The present disclosure refers to a mobile telescopic hydraulic crane, which may include at least one service opening in a terminal portion of a telescopic section adjacent to at least one hydraulic connector, wherein said at least one service opening is configured to allow access for a hand tool from the outside of the telescopic section to establish or disassemble a hydraulically sealed connection between a flexible hydraulic pipe and associated hydraulic connector within said telescopic arm. The at least one service opening allows for a quick and simple replacement of each hydraulic pipe within the telescopic secondary arm without significantly reducing the carrying capacity and reach of the crane.

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 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.

An attachment is described that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break out (i.e. disconnection or disassembly) from another section of pipe and/or make up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint to a predetermined torque value, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.

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 hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

The present invention relates to a load handling equipment and, more specifically, to an equipment for handling load bales tied with wire. The equipment of the present invention comprises at least one locating portion (11, 110, 1100), the locating portion (11, 110, 1100) comprising a gripping element (12, 120, 1200) formed by two gripping parts which move away and approximate to get the tie wire, wherein approaching and moving away the gripping parts is accomplished by means of a pneumatic cylinder (14, 140, 1400).
