A railroad crane with rigged extendable boom.


Topology: quads only.

Units: metric.

Bounding dimensions (in transport pose, with compressed and non-inclined boom, approx.):

Length: 11.5 m;
Width: 3.14 m;
Height: 5.13 m.

Railroad carriage wheel pair width standard: RU/SU 1520 mm (yet wheel pairs could easily be modified to conform to 1435 mm railways).

Materials: all procedural PBR, based on Principled/Emission shaders, thus widely compatible with modern PBR renderers. All details such as bumps, letterings etc. are done via material Nodes mathematically. No texture files (raster images) used.

All objects of the model are properly parented to each other and grouped into single Collection.

Possible manipulations:

Main platform support legs (all four separately) - via LegFL (front-left), LegFR (front-right), LegRL (rear-left) and LegRR (rear-right) rotations (proper local rotation constraints are set for convenience);

Support legs extenders (two for each leg) - have no constraints for extension, typical extensions (used in one of turntables) were 30 cm along Z.

Main platform transport ramp locks open/close rotations (separately for left and right lock) - via PltLockL and PltLockR rotations respectively (proper local rotation constraints are set for convenience).

The whole crane platform against the main platform rotation (360 degrees) - via Rotator rotation (horizontal axes rotation constraints are set for convenience);

Cabin doors (left and right separately) - via DoorLHolder and DoorRHolder rotations (proper local rotation constraints are set for convenience);

Railings side door rotation - via CPltRailingsRDoor rotation (proper local rotation constraint set for convenience).

Crane boom incline - via ArmatureBoom bone rotation (in object mode) - rotation constraint is set; other objects/bones are rigged properly to rotate and extend steel boom supports automatically;

Telescopic boom part extension - via ArmatureBoomExt bone moving (in pose mode) - max extension distance constraint is set for convenience.

UV maps unwrapped, being non-overlapping for every object except springs (those are assumed solid and are quite high-polygonal by themselves anyway).

HDRi environment map (Blue Grotto, public domain) packed in .blend for more realistic reflections, as well as put into supporting items separately.

All imagery is done via Cycles / Filmic, no post-processing.
