1:50th Scale Sennebogen 683 Tracked Telescopic Crane

Sennebogen 683

This is the Sennebogen 683 telescopic boomed tracked crane from Ros. The model features a superbly detailed tracked undercarriage with individually linked metal tracks on extending frames. The track frames have rotating idler and drive wheels which are sprung loaded to keep tension on the tracks which rotate freely. The undercarriage casting includes front and rear mounted counterweights complete with lifting eye details.

The cab is mounted to a tilting mechanism which allows about 20degree of movement. There is a access panel below the cab with authentic cutouts while the cab frame has rear view mirror and grab rails added. The operator station is finely detailed with seat, joystick controls, track direction levers and a side mounted control panel all visible through the clear windows.

The main boom is metal with a single hydraulic cylinder which is stiff enough to hold the boom in the raised position. There are four plastic extending booms and the boom head is also plastic with machined metal pulleys and guide rods. One dissapointment is the use of white thread for the rope which looks odd and would have been much better in black although this is something that the collector can easily change.

The rear of the model features two cable drums with the rear one used to raise/lower the main hook. The grey counterweights are cast as one piece but they do look like they are separate which gives the model a more realistic look. The addition of locking chains and the working counterweight lifting mechanism are an excellent tough and it is a shame that Ros chose to fix the counterweight in place. The Sennebogen name is embossed in the lower counterweight sections while the side sections have well defined red and white warning markings.

The side of the model has authentic silver coloured tread plate panels and grab rails along with rear view mirror and access steps. Authentic warning markings have been added and the paint finish is good overall with sharp Sennebogen markings on the sides and boom.

This is another great model with plenty of detail and a heavy feel with great looking metal tracks. I hope this model is also produced in the blue/grey colours as seen at Bauma.
