A crane, a construction machine or an industrial truck, with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components visible from the control station, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, wherein a movement simulation module is provided for determining movements and/or deformations of the machine components according to the inputted control commands, depending on which the graphical simulation module calculates the virtual representation. Proposed is a data emulation using hardware components, which carry out actual actuating movements and thus simulate “actual” actuating movements of the machine to be simulated, in order to provide corresponding movement data more rapidly and with less computing performance, whereby a more realistic simulation can be achieved in real-time or almost real-time.

A pipelayer machine may comprise a machine chassis; an operator cabin supported by the machine chassis; an engine supported by the machine chassis; and a boom coupled to the machine chassis. The operator cabin may include a seat assembly. The operator cabin may be stationary with respect to the machine chassis. The pipelayer machine may comprise a front portion and a rear portion. The engine may be provided in the rear portion. The boom may be provided forward with respect to the seat assembly.

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.

An operator seat is arranged in a cab. An air-conditioning unit is arranged in front of the operator seat. A lower window through which the outside can be seen from the inside of the cab is arranged in front of the operator seat and laterally to the air-conditioning unit.

The present disclosure relates to a frame assembly of a heavy duty vehicle including an operator cabin. The frame assembly may comprise a superstructure frame having a first flange at least partially protruding from the cabin supporting frame mounting portion and having a collar and a plurality of first flange bores. The frame assembly may further comprise a cabin supporting frame having a first mounting section including a plurality of first mounting section bores, a first guiding member, and a second guiding member. The first and second guiding members may be configured to engage the collar for safely guiding the cabin supporting frame relative to the superstructure frame into a final assembling in which the plurality of first flange bores may be aligned with the plurality of first mounting section bores.
