Waler93's Pneumatic Crane Truck v2

[DLuders]

Waler93 just posted this

of his Lego Technic Pneumatic Crane Truck, Version 2. It is a finalist in the Lego Technic Challenge. It is featured on the LUGPol Forum (in Polish). Here is the English translation:

"I present my first official POWER!

The day has come where I can present completed by the sweat of his forehead and under pressure of time-a Crane Truck. Construction began in early August, and the incentive to commit the model was the Lego Technic Challenge (as already mentioned in the "announcement" model). The model was done forcibly August 15 (last call for sending in the works), but I wanted to make some changes in his appearance. The first version you can see here , and on the http://technic.lego.com/en-us/Competition/voting.aspx where you can vote for him and 19 other models in the competition only for AFOLs.

But to the point.
What truck is, everyone sees, but what it sits - already a hurry to explain.
At the beginning of construction, I set myself, that the model is to be the most bawialny. Look in vain in the weight of motors, receivers, and three pilots for its service. Instead of all this we have a bunch of switches, valves, and cogs.
But I can not say that the model is completely manual, because I lied;)
When we look closely at the model we find

The PF-s:
- 2 Engines Medium
- 3 Swiches
- 2 Sets of LED lights
- 1 bbox
- 1 Extension wire (50cm)

The Pneumatics:
- 4 Pneumatic Actuators
- 2 Small pump
- 1 small cylinder
- 3 Valves
- 1 Airtank
- 1 gauge
- Almost 3 meters in the pipe

One motor PF is responsible for auto compressor. It is connected with two young pompkami 1:1 ratio. By "stick" pressure of approximately 2 bar (a pressure switch is set to this value) the need for less than 30 seconds. Placed air in air tank lasts for a few moves the actuator, then the compressor turns on automatically. By raising the pitch, two actuators are used, and to lift one arm. Crane with a maximum pulling arm is able to lift the 100g. A small load arm compensates for large capacity dump truck. Without the problem is able to pick up two dumbbells (White valve is responsible for carrying packages, green for raising and lowering the bottom of the lift, and the yellow top)
The second engine is responsible for marketing the PF and out of the lift / retraction of the supports. It is connected with the transmission mode Z12 -> Z20. Rotation of the lift is done by the worm, coupled with the clutch, so there is no option grinding mode when it will stop at the market. The same goes for props. Here also is applied to the clutch.
Addition, the truck is equipped with front and rear LED lights, turned on and off switch.

This is the same as applies to pneumatics - used in electrical MOCs

It is typically a manual turning of the wheels, ride, lift cabins, motor boxer 6-cylinder (yes, I know that such a truck is not installed, but otherwise there was no room), opened the door and side dump or lowering feet from the supports. What else goes for a piston engine is that it is driven by a chain. When they were founded pulleys and rubber have been imposed, the engine jumped and walked unevenly. Application of the chain modes Z24 -> Z16 has removed this problem.
A bit about the construction: It is typically liftarmowa, Brick can be found only on the pace and the radiator grille. Bbox can be removed, so there is no problem with changing the battery. Cabin is built of panels and Lifts and slightly resembles that of Scania, but it was modeled on it. To build a truck I used 15 frames, 37 gears, and a slew of 15L and 13L Lifts.

Total weight 2700g, height measures 25 studs, 21 wide and 74 studs long. (Dimensions in mm: 195x167x581)

Specifically, what has changed compared to the previous version of the design of the cab, the crate was lined with brickami, improved stability of the crane and the entire structure has been strengthened."

That's fantastic! it's like the lovechild between the Hauler, Crane Truck and Cherry Picker

I like the back, especially how the outriggers are 'beefed up'. It gives it much more substance and a sense that they're there not just for show. The small operators chair is a nice touch too.

Nice, very nice

Backend looks nice, but somehow the cab and front grille don't really appeal to me.

Looks great! I like it!

An excellent creation. I like both the look and functionality of it!
