An operator cabin may include a frame; a seat assembly supported by the frame; and one or more operator controls to control one or more components of a pipelayer machine, the operator controls being supported by the frame. The frame includes a front surface; a rear surface opposite the front surface; a first lateral surface; and a second lateral surface opposite the first lateral surface. The front surface may comprise a first front support structure and a second front support structure opposite the first front support structure. The rear surface may comprise a first rear support structure and a second rear support structure opposite the first rear support structure. A first distance between the first rear support structure and the second rear support structure may exceed a second distance between the first front support structure and the second front support structure.

A crane, in particular a loading crane, includes an arm system that has a plurality of arms. The crane also has a crane controller that is configured, in a coordinate control operating mode, to control the coordinates of the arm system. The crane controller has a user interface, and the user interface has at least one function which can be selected by a user and by way of which at least one of the degrees of freedom of the arm system can be restricted or is restricted in the coordinate control operating mode.

This invention relates generally to a deck with a slidable platform such as for use in construction. In one embodiment, the a deck includes, but is not limited to, at least one fixed member positionable on a floor of a building, the at least one fixed member including at least one drive mechanism coupled thereto or disposed therein; at least one extension member that is coupled to the at least one drive mechanism, the at least one extension member operable to retractably extend from the at least one fixed member beyond an edge of the floor in response to actuation of the at least one drive mechanism; and a platform that is detached from the at least one fixed member and that is coupled to the at least one extension member such that the platform is operable to retractably extend beyond the edge of the floor in conjunction with the at least one extension member, the platform including at least one wheel operable to interface directly or indirectly with the floor of the building for distributing at least some weight from the platform to the floor of the building.

The present invention relates to a lattice piece for a crane boom consisting of a first and a second lattice section element, each comprising a first chord member which extends substantially parallel to the longitudinal direction of the lattice section element, a second chord member which extends substantially parallel to the longitudinal direction of the lattice section element, a first web member which is firmly connected with the first chord member and the second chord member, and preferably extends in the plane defined by the first chord member and the second chord member, wherein a first web member is firmly connected with the first chord member and rises from a plane defined by the first chord member and the second chord member, wherein at its end facing away from the first chord member the second web member includes a fastening means for a releasable connection.

A crane including a traveling body, a boom supported by the traveling body, and a camera supported by the boom, in which an image is taken by the camera, has control apparatus; a display; and a sensor for acquiring coordinates of the camera. The control apparatus acquires map information in a range of the crane, displays the map information on the display, and displays an image taken by the camera at a coordinate position of the camera on the map information.

The focus of the present disclosure is on portable cranes and cantilevered base systems. In particular, portable cranes and cantilevered base systems which are lightweight, easy-to-operate, safe, inexpensive, and have extended reaches with high-load capacities would be advantageous for a variety of applications. A cantilevered support to a pivotable arm that is provided by the present disclosure provides advantages when compared to other portable cranes, such as the ability to: 1) extend an arm and reach of a crane, 2) increase a load that can be lifted or lowered, 3) operate a portable crane and cantilevered base system freestanding without attaching a base to a floor, surface, or bed of a vehicle, and 4) augment the structural capacity of a portable crane and cantilevered base with mechanical devices to support a variety of applications.
