    摘要： A counter-balanced mobile device and a crane are provided. The counter-balanced mobile device comprises a counterweight rack (10), a connection assembly (20), a transmission assembly (30) and a driving member (40), wherein the counterweight rack (10) is configured to be connected with a turntable (100), and the connection assembly (20) is configured to be connected with a counterweight (200); and the connection assembly (20) is rotatably connected with the counterweight rack (10), the driving member (40) is fixed on the counterweight rack (10) and is connected with the connection assembly (20) by the transmission assembly (30) to drive the connection assembly (20) to rotate, so that the distance from the connection assembly (20) to a set reference on the counterweight rack (10) is adjusted. The counter-balanced mobile device can change the position of the counterweight (200) relative to the turntable (100) under the condition that the counterweight amount is unchanged, so that the counter-balancing performance and the stability of the crane are improved.

    摘要： The invention relates to a jack-up offshore platform (1), comprising a work deck (2) and a lifting device (10) for manipulating a load (55) from the work deck (2). The lifting device (10) comprises a main boom (14) for manipulating the load (55), which main boom (14) is pivotally connected to support means (20) at pivot (13a). The support means (20) are provided to support the pivot (13a) in an elevated position with respect to the work deck (2), which allows to manipulate heavier loads and moreover saves space on the work deck. In a preferred embodiment, the platform further comprises counterbalancing means (24) that are connectable to the platform (1) and/or the support means (20). The invention also relates to the use of the platform for assembling and servicing a structure (50) at sea.

    摘要： A telescoping camera crane (30) has mechanical drive (102) and camera platform leveling systems (50,104,342,260,450), allowing for water resistant or submerged operation. Telescoping sections (54,56) of the crane arm (35) are driven by a hydraulic system (100), for smooth and near silent extension and retraction movement. Camera platform leveling and stabilizing systems (50,104,342,360,450) keep the camera level. A shock and vibration isolator (540) for the camera has a vertical axis system, including a base (548), an arm (558) pivotably attached to the base, and at least one spring (566) connected to the base and to the arm. One or more dampeners (590) are connected to the base and to the arm. A horizontal axis system (610) is supported by the vertical axis system. A leveling linkage (602) connects the vertical and horizontal axis systems. The leveling linkage has adjustment features that allow for compensation of camera lens angulation caused by movement of the camera (536) supported on a vehicle (32) rolling over rough or uneven ground.
