[MOC] Skip Loader

[damjan97PL]

Hi Everyone.

It's my new model ,  a skip loader.

Dimensions:

-Lenght: 46cm

-Height: 27,5cm

-Width: 15,5cm

-Weight without container: 2550 grams

-Weight with conatiner: 2900 grams

 

Few years ago I also built a 3 axle skip loader.

This is more advanced and looks better.

Model has a full suspension, tilted cabin under which is a working R6 engine. 

Behind a cabin is a BatteryBox.

Truck is propeled by 1 XL motor with 2.33:1 ratio.

First and last axle are steered. Third axle in opposite direction to first axle. Steering by Servo motor.

A third axle is also lifted with automatically detachable steering with clutch system. 

Operated by 2 M motors, one for lifting a axle and second for clutch steereing.

Rear support foots are operated manually.

I used 2 small linear actuators. 

Lowering the arm is operated by 2 long linera actuators propeled by L motor with 8:1 ratio.

Arm is little to high but its a only one solution to accord a minimum height after lowered the arm and range of arm.

Arm is lowering slowly, almost one minute. 

All functions are controled by sBrick.

Cabin has a openable door and detailed interior.

All functions are working fine and truck is driving and steering good.

I'm waiting for your comments :)

Very attractive model! The 3rd axle especially is very impressive - would you be able to show a picture of it from the underside? Curious to see how it disengages/engages, and still allows suspension travel.

Every time is see a truck with Arocs wheels I really wish Lego would give us one, too :-)

Really nice model!

Dito! I looks like the springs of the third axle are compressed when in the upper position and thats why you need two motors?

Springs are mounted to lifting mechanism, so they are lift with axle.
