After finalizing the Slurry Injection Tanker I
thought it should be easy to reuse the chassis for the development of a tipping trailer,
which was easy to do. The only challenge was the tipping construction itself,
because the technic linear actuator can only extract 5 studs. This was achieved
by building a 'helper trailer bed' which has two functions:
a) make sure that the trailer bed can extract much more then 5 studs,
b) gain more momentum on the trailer bed itself in the first phase of the
tipping process. Important is the axle 7 which connects the linear actuator to
the 'helper trailer bed'; the axle ends do push in the first phase to the bottom
bricks of the trailer bed (see red arrow on last picture of this
page).
As such, this trailer is be able to tip a reasonable load.
The tipping trailer can be connected to the
original LEGO® Technic Tractor set 8284. No Tractor modifications are needed, just the
mounting of a tow-bar.
The technic specifications of the 'Tipping
Trailer' model are:
* Tipping of the trailer bed with steering wheel on the
trailer
* Individual pendular suspension on
each side
* Parking wheel
The dimensions are:
* Length: 34 cm
* Width: 16 cm
* Height: 15 cm
* Weight: 0,9 kg
* Number of parts: 649
* Development time: <25 hours, MLcad time: <15 hours
Children
modification:
Little children want to tip the ‘tipping bed’ with
their hands. They just can not (or don’t want to) operate the tipping bed by
turning the steering wheel which operates the ‘linear actuator’.
Tipping 'by hand' is possible when you disconnect the linear actuator from
the tipping bed as shown on the picture.
And, the linear actuator can still ‘lay flat’ under the tipping bed; you don’t have to remove it.
