The invention relates to a drive device for supplying power to multiple engine pumps (4, 5), provided in the superstructure (3) of a mobile crane for superstructure functions, by way of a drive motor (2) arranged in the undercarriage (1) of the mobile crane, comprising a hydraulic motor (7) which is arranged in the superstructure (3) and hydraulically driven by the drive motor (2) and which comprises a first mechanical output which couples at least one first engine pump (4) to the hydraulic motor (7) and a second mechanical output which couples at least one second engine pump (5) to the hydraulic motor (7). The invention also relates to a mobile crane comprising this drive device.

The invention relates to a mobile construction crane comprising a superstructure and an undercarriage, wherein one or more electrical consumers are provided in or at the superstructure, wherein a supply of the one or more electrical consumers with electrical energy takes place by at least one current generator installed in the lower undercarriage.

A structure installation system which maintains one or more walls in a desired position and orientation during installation of the one or more walls. The structure installation system generally includes a vehicle which is adapted to traverse a ground surface. The vehicle includes an arm having an arm coupler to which a support is connected. One or more walls adapted to be installed in the ground surface may be removably connected to the support, such as by securing the walls to adjustable hangers that are removably connected to the support. By adjusting the positioning of the hangers, the orientation and position of the walls may be adjusted. Once put in position, the vehicle and support will retain the walls in the desired position and orientation while concrete is poured and allowed to cure to form a unitary structure such as a bollard wall.

A pipelayer includes a frame, a plurality of ground engaging members movably supporting the frame, a prime mover, and a boom assembly and a counterbalance assembly supported on the frame. The boom assembly includes a boom. The counterbalance assembly including a counterweight, the counterweight being movably supported on the frame to counterbalance the boom assembly. The counterweight includes a battery box including at least one battery. A control strategy is also disclosed.
