Dubonnet? is this something like McPherson? some progress

The side movement is more or less zero.

A new driven steeringAxle for an upcoming 6x4/4 chassis. The suspension travel is only roundabout a half stud, but the Frame could be very low. if it works good enough i will make later an .IO and put it in the axle collection thread.

i have only used the hoses from the set.

More than this distance is not possible without extra counterweight. In this condition the rear outriggers are barely touching tne ground @Chipstertrain, its to far away for me.

Test 11 and the stability problems seem to be solved. A new upper collumn and a quarterpiece turntable with 1x1 round tiles between the two parts working finally

standard size when mounted like on the pictures

A few pictures for the hosing. Uppercarriage to the boom 8x 140mm, boom to main actuator 4x140mm, Boom to stick actuators 6x110mm, stick actuators to connection 2x110mm, connection to bucket actuators 4x 140mm

Thank you very much.

For water use on it is neccessary to drill up the intakes in the cylinders. Then it goes much easyer with a liquid fluid.

hm, looks ok. does it block too when the bucket is not mounted on the boom?

Thank you very much.

Test 10 of my self Raising Crane. Unfortunately the Base counterweight is not enough for rotating with the transport chassis on the hook. And i have discovered a small problem with rope suspension of the boom.

The Basic Counterweight is done and should be enough to rise the Crane. Maximum hook height is actually at 95cm and the Boom is 126cm long

Please make a picture of your build

The Rolling chassis is now complete. The Trailer axles are suspended. [ edit: Trailer for counterweights when Crane is upright.

There are nstructions LEGO MOC-29973 Custom RC Dump Truck Muldenkipper (Technic 2019) | Rebrickable - Build with LEGO by the way, the backhoe instruction on custombricks is online. https://www.custombricks.de/CUSTOM-Bauanleitungen/Technic-Mocs/42019-DE.html

Is it only me or is this the silhouette of a countach?

Front Part is done, now the rear axles

A part of the Gooseneck is done

A small break for lunch.

Thank you very much

The white Towers representing the ballast weight which is mounted permanent on the Model. They are filled with roundabout 630 g 6mm Steelballs. Together with the Batterybox this is more than 800g Counterweight. Enough for light duty and on top is space for more. schnelleinsatzkran 2 by Michael Wirth, auf Flickr

The Sled is now working properly with 3 Batteryboxes. Next Problem is the outriggerbase. Under Load it is leaning to the Side.

The winch itself can handle 3 Batteryboxes including their batteries. The sled has problems with this weight to move. Another point to improve.
