Tipping trailer (2009)
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 must be connected to the original Technic Tractor set 8284. No Tractor modifications are needed, only 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: 624

* Development time: <25 hours, MLcad time: <15 hours

MLcad files:
The Tipping Trailer is made up of several sub models within just one mpd file.

    MLcad files zipped with WINrar

The following MLcad files are used:
* Tipping trailer.mpd                                            
        Tipping trailer.ldr
        Grating.ldr
        Linear Actuator.ldr
        Parking wheel.ldr
        Pendular suspension frame.ldr

        Tipping bed.ldr
        Tipping mechanism.ldr
        Tractor8284 tow bar.ldr
        Wing left.ldr
        Wing right.ldr

MLcad unofficial part list
Please navigate to the 'MLCad parts library' page on this website if you having trouble with the correct reflection of the *.mpd and/or *.ldr files within MLCad or LDview.
Probably you do miss some (or all) unofficial parts I did use within the model.

Adobe PDF building instructions
The building instructions are also available in the Adobe PDF document format.
Please consider that this download takes a while due to the size of the WINrar file (~12 Mbyte). 

MLcad building instructions:
The following information will help you to build the Tipping Trailer model without to much trouble.

1) Technic models nowadays uses frequent 'mounting axles' which must be 'pushed' into a sub-model part which was build separate. Within the MLcad files, these mounting axles are already in 'pushed' position. Keep this in mind when you want to mount individual sub models.

2) Start first with the 'export' of all the sub-models of the .mpd file into one directory. This gives you the opportunity to load every sub-model into the LDview program, so you can take a close look to the sub-model from every perspective.

3) Start to build all the sub-models BEFORE starting to build the 'Tipping trailer.ldr' file. This file starts with the main chassis of the trailer,  but acts as an assembly file for all the other sub-models as well.

4) All the sub-models can be placed as 'one unit' on the Tipping Trailer model.

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.

LDview:
Version 3.0 of LDview will give the correct 3D views of the Tipping Trailer. Previous versions had problems with multiple ldr files loaded into one mpd file.
