Video of New Lego Technic 8069 Backhoe Loader

Inventory?

Looks very boring but some usefull parts on it

7 different moving functions is boring? Jeez, you're hard to please.

today rings the doorbell and my two 8069 from amazon arrived me. i was very surprised that they comes at Sunday.

ok, building process is Easy, but the first of the two books contains an optical error. on book 1, page 5 step 6 sits an blue cross to round Bolt in the wrong position. first i had thought this is an new part

there are four mLAs with the number 4612100, and four from the new part with the number 4610371. Sorry i dont know the correct description, but it is the part which is placed on the end of the boom of the new 8067 minicrane.

the size of the Backhoes 8069 and 8455 is nearly the same. only the 8455 digging arm is longer.

i think it is a good prize( 50€ at amazon and 40€ at the real Supermarket in Germany) for the 8069 Backhoe

i have this set, there on the shelfs for 49.99 euro in Belgium. the new LA's seem intresting, but i have some problems with them.

- the new mini LA's feel cheaper than the current LA's. the plastic is not as stiff, you can really feel it on the mounts.

- they dont deliver much power, they seem to click through when they are handling a too heavy load. when i push a bit on the bucket of the 8069, they just click inside, like they really don't want to raise.

i havent really tested them in a model or something, this is just what i concluded while playing with the 8069.

8455 looks better to me, too, but we all have different tastes.

8455 looks better to me too, just because pneumatics look better/more authentic with all those cool hoses!

This new set looks kinda tedious to play with, with all that nob turning.

I like it but im a great fan of pneumatic!! so i go for both

Im also a fan of pneumatics but im starting to prefer la,s simply because there more accurite on diggers etc,pneumatics are not suited for lots of differant things as when u activate them they just go to fast.

That is correct for display models they are fine but to use i prefer L,A's also.

I think it's a good model..to exercise your finger by turning those tiny knobs, especially for all ye spoiled AFOLs who are used to the convenience of PF operations! Hahaha, just kidding! Even though I own the 8043..I still love to manual turn the knobs on my tiny 8047 mini excavator! But seriously, for the price, the many features, the 8069 is really good I'll buy it.

I like the set , but don't know yet if i would buy it , there are usefull parts , i really like the new LA's.

BTW anyone knowes if the LA's are on BrickLink or somewhere else allready ( i could'nt find them )

The new mini Linear Actuators (mLAs) are cataloged on Bricklink as 92637c01 "Technic Linear Actuator Mini with Dark Bluish Gray Head and Orange Axle":

I am not sure how anyone could compare their own model and say it's better than an official Lego one just because theirs is larger and they have added more functions. And after all, it is only a $60 set, so in my opinion you are definitely getting what you pay for here. This small backhoe looks pretty good and yes it is rather simplistic to turn knobs, but this one is a little small for adding battery boxes and motors or running miles of air tubes through. I think that Lego is more concerned with the appearance as well as the functions.

Got it today and I have to say it looks pretty good. I mainly got it for the mini-LA to play around with them and try them. But on a second thoguh I might build the LEGO model first.

In my opinion it has a very good selection of parts. Quite small form factor and loaded with functions.

For me it is definately a

On February 16, 2011, the Lego Technic Designers Blog posted this full-page description of the new mini Linear Actuator (mLA):

"This year we expanded the system with a new smaller linear actuator in the 8069 Backhoe Loader.

A few years ago we introduced the linear actuator in the LEGO Technic system. This year we expanded the system with the new smaller linear actuator in the 8069 Backhoe Loader.

Linear actuators work by converting a rotary motion into a linear motion. Before we had the linear actuators we used different methods of getting the linear movement in to our models. One way can be seen here:

When combining a worm gear (1) with an 8-tooth gear-wheel (2) running on one or more toothed racks (3) you can build your own "linear actuator" by pushing the racks back and forth with the small gear-wheel.

The LEGO Technic linear actuators works in a similar way and fits perfect in to our building system and our models - especially when used together with the Power Functions motors, like in big crane arms. Try to take a look at the 8258 Crane Truck and the 8053 Mobile Crane, which both uses the actuators. Both models also have other ways of linear movement - can you guess what those are?

Because the linear actuators are very powerful, we added a clutch mechanism in both the large and the small actuator. The clutch acts as a safety mechanism; breaking off power to the actuator when the power reaches a certain limit. The clicking sound you can hear from the actuator when it is at its maximum or minimum reach is the clutch being activated.

Now let’s look inside the large linear actuator:

The orange part (1) is where you put the input axle - the rotating movement. On the inside of the orange connector you see the clutch assembly (2). The clutch drives the white threaded tube (3) which pushes the threaded metal-piston (4) in and out.

Because the small linear actuator only is one module wide, it works a little bit different:

The orange part (1) is the input axle which extends all the way through the threaded tube (2) and has a built-in clutch function at the end of it (3). The threaded tube (2) is also the piston of the actuator.

So why not just use pneumatic cylinders instead? Well, all actuators are self-locking, which means you can't push the piston in and out by hand. That gives you the possibility to control the position of the piston very accurately even when lifting heavy loads. When using pneumatic cylinders that is more difficult. However, the big advantage of the pneumatic system is that it is much easier to get the power to the cylinder. You don’t need to build a long drive-train with cross-axles and gearwheels. You just run two pneumatic hoses from the valve to the cylinder and that’s it. So depending on how precise or powerful your function has to be, you have to select either a linear actuator or a pneumatic cylinder."
