A crane system having a gas turbine that has a manhole on the outer housing thereof, the manhole being designed to open up a maintenance access to hot gas parts of the gas turbine in the open state of the manhole, which is provided with a fastening section; the crane system further has a hoisting mechanism that includes a mating fastening section which is connected to the fastening section of the manhole in such a way that the hoisting mechanism introduces weights that same has to lift into the outer housing of the gas turbine.

A jib crane, having a low-weight boom with a proximate end, a distal end, a top, a bottom, and a first length between the proximate and distal ends. A high-strength brace extends along the top of the boom from the proximate end by a second length. The boom is mountable to a support structure by way of the brace. The second length may be less than the first length and the brace is attached to the top of the boom and to a pivoting bracket, which is pivotably mounted to the support structure.

The invention relates to a device (10) for the hand-guided movement of loads by means of a retaining or gripping element (11) as a lifting aid, which retaining or gripping element is attached to a load-bearing rope (2), comprising a load-bearing apparatus (1), which is provided with at least one vertical cantilever (3), over which the load-bearing rope (2) is guided from sides of a rope-winding apparatus (4) on the load-bearing apparatus (1) by means of an adjustable rope articulation point (5), wherein a sensor (6) for measuring a rope angle of the load-bearing rope (2) in relation to the vertical is provided and a controller coupled to the sensor (6) is provided, which controller is designed to simultaneously control an adjustment of the rope articulation point (5) and a rope length of the load-bearing rope (2) on the basis of a measured rope angle.
